A decentralized storage network that transforms cloud storage into an account market. Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it.
Filecoin announced, that there will be more delays before its main network is officially launched.
Filecoin developers postponed the release date of their main network to late July to late August 2020.
As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process.
Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market.
Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors.
The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020.
They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit.
The Filecoin team noted the following:
“We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks.
Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet.
The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020.
The updates to the project can be found on the Filecoin Road Map.
Filecoin developers stated:
“This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage.
Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain.
In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards.
Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21.
Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price.
Mining in Filecoin
In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency.
Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data.
Filecoin will contain several types of miners:
Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out.
Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power.
Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network.
The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into.
In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.

Hardware recommendations

The current system specifications recommended for running the miner are:
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars.
Proceed to mining
Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract.
Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually.
After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started.
Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page.
At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention.
Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt.
Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network.
Duration of operation, cutting and penalties
“Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network.
In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error.
Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily.
An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection.
The sector will pay an error fee after the penalty of the sector once the error is discovered.
Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network.
Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function.
Filecoin miners
Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.”
With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices.
Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless.
Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers.
Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network.
However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners.
These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB).
Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development.
“Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital.
“Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said.
Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT.
In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive.
To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day.
As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force.
The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million.
This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs.
After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020.
The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process?
Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance.
In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners:
The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue.
It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown.
It seeks to promote mining using Filecoin Discover
Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day.
Ian Darrow, Head of Operations at Filecoin, commented on the announcement:
“Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”.
Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more.
Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds.
In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations.
The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested.
“The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”.
IPFS and Filecoin
Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure.
IPFS
It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live.
The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides.
Using IPFS
In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data.
Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service.
Using Filecoin
The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone.
Filecoin, powered by IPFS
It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS.
Some advantages of sharing Filecoin with IPFS:
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol.
Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated.
PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage.
In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected.

Ethereum 2.0: Why, How And Then?

Ethereum 2.0: Why, How And Then?
Why update Ethereum? One problem of the Ethereum network that the update should solve is scalability. At the moment, its blockchain can perform to 15 transactions per second, which is over two times more than that of bitcoin. However, this speed is still not enough for a large number of users. For example, the Visa payment system can perform up to 24 thousand transactions per second.
Adding an Optimistic Rollup technology will help to solve the scalability problem. According to Vitalik Buterin, the creator of Ethereum, its implementation will occur after the network’s update and will increase its throughput to 1000 transactions per second.
by StealthEX
Another solution to this problem is a change in the algorithm. Currently, Ethereum runs on the same protocol as Bitcoin, Proof-of-Work, confirmation of transactions in the cryptocurrency network occurs using the computing power of processors.
Using the Proof-of-Work algorithm limits the growth of the Ethereum network bandwidth. To withstand a large load, more miners are needed, but the growth of their number slows down since it becomes more difficult to mine cryptocurrency and, consequently, less profitable.
This is the reason the Ethereum development team is planning to switch to the Proof-of-Stake algorithm. Unlike the PoW, it does not require the use of computing power to confirm blocks. Instead of miners, transactions will be confirmed by validators. To become a validator, the user should have 32 ETH and install a special client. From a technical point of view, this is easier than buying mining devices and maintaining their functionality, as well as looking for access to cheap electricity. Thus, the system will no longer need expensive hardware.
The main solution to the scalability problem will be to implement sharding. Current Ethereum network is a unified database. After the update, the blockchain will be divided into autonomous, interacting blocks — shards, each of which will process particular transactions and smart contracts, which, however, will be recognized by the entire Ethereum blockchain. Nodes that form the shard process information separately, this allows maintaining the principle of decentralization. This is important since the risk of centralization is another big problem of the old algorithm.
Since the complexity of mining has increased over time, and now this process requires having expensive equipment and access to cheap electricity, small participants can not afford to stay in the game. In such conditions, big pools of miners that can provide higher productivity have a decisive advantage. For example, in April, more than 50% of the computing power of the Ethereum network was provided by only two mining pools. This creates a significant risk of centralization and “51% attacks”.
Validators will confirm transactions and get rewards in the form of passive income. According to the project’s roadmap, this amount will vary from 1.81% to 18.1%. The profitability of the stacking will depend on the number of validators. The more of them, the smaller the amount they get. However, there will be some costs. In the same Ethereum 2.0 roadmap, developers mentioned that the cost of validating transactions, based on rough calculations, will be about $180 per year. One of the developers of the project, Justin Drake, predicts that on average the validator will receive an income of 5% per year.

What is the estimated Ethereum 2.0 release date?

The launch of Ethereum 2.0 will take place gradually, in six stages, the “zero” of which is expected this summer. However, it is worth noting that due to finding vulnerabilities, the dates have already been shifted several times–initially, the transition to the new version was planned in 2019.
One of the developers of the project, Afri Schoedon, said that the launch could be postponed to 2021. According to him, under favourable circumstances, the main network can be presented in November of this year, but there are certain difficulties in this.
Schoedon explained that before launching ETH 2.0, all of its clients must be brought to the same specifications. After that, the developer’s team needs to open a unified deposit contract so that users can transfer their assets from the old chain to the new one. Between these stages, developers also need additional time, so they could test all aspects of the new system.
As it usually happens, there’s going to be two parallel blockchains as a result of the hard fork. The first one, ETH1, will continue to work using an old protocol, while the update will be implemented on ETH2. Users will be able to transfer their coins from the old blockchain to the new one, but not vice versa. The appearance of sharding will allow developers to move to phase 1.5 — during this phase, ETH1 will merge with ETH2, becoming one of the 64 “shards” of the updated blockchain. In the second phase, smart contracts become available on ETH2, which can be considered the full start of its economic activity.

And what are expectations?

Updating the Ethereum network will increase its technical capabilities, namely, it will speed up and reduce the cost of transactions, as well as make the blockchain less vulnerable for centralization process.
Currently, the absolute majority of decentralized finance projects are developed using the Ethereum platform. The Ethereum 2.0 release will probably attract even more partners who will use the blockchain for their projects.
Ryan Watkins, Messari Analysis company’s researcher, highly values the importance of updating.
“ETH 2.0 is a much stronger catalyst than the Bitcoin halving simply because it’s an uncertain and fundamental change.” — Ryan Watkins wrote on his Twitter account
And the part about uncertainty is hard to disagree with. Of course, there are some concerns about the bright Ethereum future. The coming hard fork carries with it potential negative consequences. For example, after switching to the PoS algorithm, the US Securities and Exchange Commission (SEC) may well admit Ethereum as a security, which will lead to legal complications similar to those faced by Pavel Durov when trying to launch his TON blockchain platform.
For now, ETH is the most popular coin for mining at home, and most of these miners will probably just leave the network.
There is also a risk that the price of Ethereum may fall. To receive passive income for storing ETH, the user will not only need to have 32 coins but also block them through a special transaction. They will not be able to withdraw these blocked funds immediately. As stated in the project roadmap, the cryptocurrency withdrawal process will take at least 18 hours. This could take even more time if many users request the return of tokens at the same time. Thus, if ETH falls in price, it will be impossible to sell it immediately, and there is a risk of losing some capital and all the income received from stacking.
Nevertheless, investors are mostly optimistic — the volume of Ethereum options on the Deribit exchange has grown to a historical high, which indicates confidence in the future of Ethereum project. The ETH price is also growing, having overcome the consequences of the March collapse of cryptocurrencies.
Most experts agree that Ethereum price will grow after the update. On the one hand, the altcoin will become more expensive, as it will become a more attractive investment. On the other hand, the offer will decrease, as users will start transferring coins from the first version of the network to the second, to block them for passive income.

Users will be able to transfer their coins from the old blockchain to the new one, but not vice versa. The appearance of sharding will allow developers to move to phase 1.5 — during this phase, ETH1 will merge with ETH2, becoming one of the 64 “shards” of the updated blockchain. In the second phase, smart contracts become available on ETH2, which can be considered the full start of its economic activity.

And what are expectations?

Updating the Ethereum network will increase its technical capabilities, namely, it will speed up and reduce the cost of transactions, as well as make the blockchain less vulnerable for centralization process.
Currently, the absolute majority of decentralized finance projects are developed using the Ethereum platform. The Ethereum 2.0 release will probably attract even more partners who will use the blockchain for their projects.
Ryan Watkins, Messari Analysis company’s researcher, highly values the importance of updating.
“ETH 2.0 is a much stronger catalyst than the Bitcoin halving simply because it’s an uncertain and fundamental change.” — Ryan Watkins wrote on his Twitter account
And the part about uncertainty is hard to disagree with. Of course, there are some concerns about the bright Ethereum future. The coming hard fork carries with it potential negative consequences. For example, after switching to the PoS algorithm, the US Securities and Exchange Commission (SEC) may well admit Ethereum as a security, which will lead to legal complications similar to those faced by Pavel Durov when trying to launch his TON blockchain platform.
For now, ETH is the most popular coin for mining at home, and most of these miners will probably just leave the network.
There is also a risk that the price of Ethereum may fall. To receive passive income for storing ETH, the user will not only need to have 32 coins but also block them through a special transaction. They will not be able to withdraw these blocked funds immediately. As stated in the project roadmap, the cryptocurrency withdrawal process will take at least 18 hours. This could take even more time if many users request the return of tokens at the same time. Thus, if ETH falls in price, it will be impossible to sell it immediately, and there is a risk of losing some capital and all the income received from stacking.
Nevertheless, investors are mostly optimistic — the volume of Ethereum options on the Deribit exchange has grown to a historical high, which indicates confidence in the future of Ethereum project. The ETH price is also growing, having overcome the consequences of the March collapse of cryptocurrencies.
Most experts agree that Ethereum price will grow after the update. On the one hand, the altcoin will become more expensive, as it will become a more attractive investment. On the other hand, the offer will decrease, as users will start transferring coins from the first version of the network to the second, to block them for passive income.

How to succesfully Invest and Basics

This was written for a different group /stocks it got deleted so hopefully this time it works !
Disclaimer
I dont want to sell you or recommend anything ! Just my expierence and little help so enjoy. If you want to ask me anything feel free, I try so answer everything.

This article is meant to be a small guide that helps you to find your way. Its based on my experience and knowledge, I gained throughout the years. Iam by far no professional. Iam just a guy who loves to invest. If you are new and have few grands to invest this article might help you.
My motivation to write this article was because when I turned 20 I got a small loan of 1 milli.... just few grands from my parents plus the savings I made from working. For me it was clear that I want to invest them. I always liked the idea making money and not really working for it! (Spoiler its kinda true and kinda not)
So I sum up few steps which will helped me to orientate and maybe help you to make your first investement
Step one 1. Where I can Invest?! You can basicly invest in everything. They are infinite options but I just cover up few topics.
They are 5 investments I would like to adress.
  1. Stocks.
    1. Real estate
    2. Options
    3. Start-ups
    4. Krypto n+1. art, old cars, drugs?! (Don’t do or sell drugs pls!)
Stocks (my fav.) I love stocks. I love understanding what the company’s plans are and where they are heading.
They are 3 different types of investment strategies.
  1. Short term (daily) That’s usually daily trading. That means you invest and sell on a daily basis. If your not a expert it can frustrating and the chances that you will lose is high. Many people forget that you have to pay taxes and fees so even if you for example invest 1.000 and sell for 1.050 within 20 min. You will have to pay some fees and taxes and with luck, you are where you started. It only makes sense when you invest a lot, otherwise it makes no sense and to be honest I don’t know any person which makes profit with it.
Difficulty: Hard
Stress Lvl: High
Risk: Medium/High
Profit: Usualy bad
Investement: Medium
  1. Mid term (6month – 1 year+) You buy some stocks for a longer period of time and hope it will go up soon.
This investment is much easier and less risky than short term. You see a stock going up and up so you invest 5k and hope you can ride a little on this upwards trend. Its fairly easy but you have to keep an eye on the market. A good example is VW it dropped because it has some Image problems. Thats a chance to invest! It will most likely to recover because its the biggest automarker in the world and it did. It happend 1000 times and normaly big companies dont fail they are exception but without risk you dont get anywhere
Difficulty: Medium
Stress: Medium
Risk: Medium
Profit: Good
Investment: Low
  1. Long term ( 1-2years – 10 years+) Means you want to invest for a long time you are not only interested in making a quick buck but making a slow and steady progress. You are not interested if the stock goes up or down but you are more interested how much divendend they pay. Usualy they go up very slowly but steady. A good example for this type of stock is Royal Dutch (shell) it has ist up and downs but compared to other stocks ist stable. The dividend is 6% which is insanly good no other big company will pay you that every year. You invest 10.000€ and get every year 600€ which means a holiday for free. Also the work is very little, you only have to check the stocks every few weeks/month You wont get rich but its better than having it in the bank.
Difficulty: Easy
Stress: Low
Risk: Low
Profit: Low
Investment: Low-Medium
Before you invest check the company read the news and get a good overview. I have to admit Iam a fanboy at heart. When a stock of one of my fav. company’s has potential and it does make sense to invest it feels like buying tickets for my favorite Rockband. You support and cheer them on and if they grow you grow with them. BUUUUUUT don’t get my wrong never buy stocks just because you like the company or they have a cool name.
All in all Stocks are a great Investment!
Real Estate
If you want to invest in houses it’s a very save and profitable investment but it depends on your area and country you are coming from. In Germany most objects are overpriced right now so it wouldnt make any sense to buy some. In generell the more money you have the better. They will will be much more people who can afford an cheap flat/condo than the other way around. So expensive objects are better! The optimum is always a shitty apartment in a very good area. Also buying objects in bad areas cause lots of trouble with tenant. Crazy families who refuse to pay, messy people etc. this can end in a stressful situation so beware of that.
If you are already rich af than buy propreties
Example
I went once to an auction and most apartments are sold for double the estimated value. It would take ages (20+ years) to get your investment back. So beware of your market situation.
Difficulty: Easy
Stress: Usualy low/medium
Risk: Low
Profit: Medium
Investment: High
Options
Options are basicly betting that a stock with go up or down. You can bet on nearly everything. You can make lot of money very quick and lose everything even quicker. For me option trading is gambling with few extra steps. The difference is you can lose more than you invest. They are cases where people invest 1000€ and lose -120.000€ because suddelny the market changed.
If you have gambling problems and tendency to gamble this is absolutly not for you. You can see here (in the forum) lots of bad examples where people going full YOLO on something and lose a ton of money. They save up a little, invest in something even more risky and lose again.
I know a friend who makes good money from it but he has a clear head and read many books about this topic he uses software to analyse the situation and everything and he admits that sometimes he doesnt understand what happend. Of course options are not the devils tool but I like to be the voice against it. The truth is in the middle.
Iam a person who likes to understand what am I doing. After reading and learning about it, for more than a year I was more confused than before. It is probably because Iam to stupid for it, so I gave it up and moved on. Options are not for me
Difficulty: very hard (at least for me)
Stress: high
Risk: low - very risky
Profit: It can be everything
Investment: low
  1. Start-ups
Start-ups are also a great business opportunity. I was lucky enough to invest once a little bit into a upcoming company from my firend. He showed me his company and the plans for the future. I already helped him with few shows and stuff so I knew how everything worked.
The biggest bullshit I ever saw are the analyse prediction of the future sales. During the last few years I saw few of them and they all predicted that the company will make an absurd amount of money. It looked like high cool project all shiny and with big numbers. To be honest I dont even know who pay these people to make such bullshit predictions, seriously.
(as you can see I love talking from my life so forgive me my dear)
Long story short I still invested because I understood their model. They existed and already made great progress. I made 50% profit in 3 years. I am still very happy and greatful to had such good chance to invest and would do it again.
They biggest question is how do I find such chances ?
Tell people you are intersted to invest maybe a friend of you will start an company and you can invest or help you to find such a opprtunity. I went to many start up meetings and talk about a lot with my friends. They dont want to hear it but I tell them anyway and if there is a chance they will call me.
Few Tipps:
- Look for already existing companys
- Most companys give you a very good inside look before you invest! If not watch out they hide something.
- Try to understand what they are doing and where they are heading
- Look what the will offer you for your money!
Difficulty: Medium/hard
Stress: Medium/low
Risk: Medium/High
Profit: Good/Very good
Investment: From Low to high
  1. Krypto
Boy oh boy where to start. I heard to many experts saying yeah krypto thats future boyyyyyy I invested everything BOYYYYYYY and in few month I will be rich BOIIIIII. I heard this story so often that Iam allgeric to it now. This irregulated mess based purly on speculations wasnt anything form me. I didnt invest a cent into it and had lots of chances when bitcoin was 300-500 €. It didnt simply fit into my portfolio. It had no function for me. You could pay for your drugs in the deep web and some hipster pizzerias accepted it but in generell it had no function. So investing into kryptos is just speclutions it has no real fundation what I like.
My friends who invested early made a ton of money but all the people on the Hypetrain crashed.
Difficulty: I dont know
Stress: Depends how much storys you make about it on Instagra´m
Risk: Over 9000
Profit: It can be everything from super high to low in just few days
Investment: What ever you want, if this is still to expensive for you, make your own coin and hope some Idiot buys it!
Now you know my knowledge ehh more like my opionen on few things now its time for……. Step. 2. Get a rough overview
Back than I didn’t know where to start so I asked everybody for advice like parents, friends , my parents friends, banks, forums, news etc. and got very different results.
Friends and family can be a good source of information how they did it. Of course often investments are impossible to repeat because they are 20 years ago but they can give some good advice. Its nice to hear few cool stories.
Example
Royal Dutch shell hast wo different stocks. One based in england (B) one Dutch version (A) (explained very simple, not 100% accurate). If you purchase Royal Dutch (A) you have to pay a 15% withholding tax that you wouldnt when you buy Royal Dutch (B).
Banks
Banks are terrible to ask. I always had shitty experience. The lured me into meetings, only to sell some shitty investment models from which they make some good money of me or some stupid insurence. They are not interested in your loses or profits they are interested to sell you the next stupid investement from which the make money. They never keep their promises and if you loose they will cheer you up and show their new hot investement and so on and so on until you loose and they drop you.
My mom works kind of in the finance sector and you wont believe home money older people lost ton of money because of this. I also found few very shady investements opportunities who would be illegal but I wont get into detail cause I dont have 100% proof for it and I also dont want to get in any trouble. As you can see Iam not big fan oft them and do not recommend!
News/charts/indexes/Forums
For me charts & news works the best. It’s easily so see what’s going on and gives you a great overview. The chart showed that a stock dropped 5%?! Good! Read the news/forums and find out what is going on! It’s that easy you don’t need 15 monitors and crazy software to understand what is happening. Dont make it to complicated! Have an easy overview about the market which you would like to invest.
Example
My parents invested around a year ago alot in Tesla. It was before Model 3 was released. Tesla had no expierence in mass production and it was clear (at least to me) that they wont have an easy start. They still made no profit and it was the first step to play with the big boys. Back than the Tesla stock was way over 300€ and it was based a lot on speculation and hype. It couldnt live up to they hype and dropped ≈ 30% - 35%.
  1. Few points & strategies
No Emotions
Never ever let your emotions guide you. Stocks are not based on a stomach feeling or any other emotion. Dont invest just because you like Elon Musk or Apple or anything. If I have a the chance to invest into one because the timing is right. Always make sure you know what you are doing. When it can wait a day, sleep a night about it and be sober! You can get sucked up into this world you will start giving a shit if you lose one grand and start digging deeper and deeper and lose sense the value of it. Stay sober and now when you have to stop.
Making losses
It will happend and dont freak out !
They are two options how to handle it and it depends on few things.
  1. Sell them, you see the ship is sinking and their no possibility you can save it than sell it, It hurts but better early than it is to late. Or you find a better possibility to invest for example a start up than its also fine.
  2. Keep it! Turning a Short/Mid-term investement into a long-term investement. Check first if the company will recover from it. For example the VW stocks dropped a lot due it scandal few years ago but it was clear that they will not go bankrupt so after a while they recover from it. Technically the market will grow infinite so after every crash they reach new heights, if you can wait that long the chances are high that you will make some profit and do not lose any money. Maybe the profit will be small but better than losing everything.
Diversity
Dont put all your eggs in one basket but also dont but every egg in a different basket. Have a good mix that you can still have an overview about your investment. Dont depend on one investment something bad can always happend. Having a good mix is important some investments will go up and few will go down. Its rearly that everything will crash (expect crises). So you can sell the good one and keep the bad ones until they go up.
Scams
Online
Stick to the basics! They are a ton of scammers online who want to show you a way to make fast money. Its mostly some MLM (multi level markting) aka Pryamide sheme, some buying and reselling some stuff from China or some weird option trading platform where pay in and your money is gone in 5 min without any trace o fit (no chance getting it back)! The Instagram advertisment is so ridiculous and I feel stupid mentioning it but hey if it wouldnt work they wouldnt exist. So please dont be this guy….
Offline
I really wanted to invest and have an own start-up. I met many people and visited countless seminars. Few of them offered me to invest but it was a mostly a mess. Onced I got fooled. A friend and I meet a person who had a start up for social media. We had some meetings restaurant he paid everything for us and looked very legit. I worked 3-4 month in this start up 3-4 hours a day, even on weekends for free. Only later to find out I was the only one working in it. (My friend pulled out very early cause he wanted to focus on his PhD) They rest oft he Team did absolute nothing! All the money the company generated was based on my work. They didnt make a lot of money but around 600-800€ a month. The founder spend all the money on vacation and stuff. I never got anything. They wanted to sell me 10% of the company for 15.000€. I always said I need more inside infos, which of course I never got. So I pulled out and they went mad and threaten me to sue me. I feel to this day ashamed that I trusted them and didnt saw it.
If you want get into something like this make a contract dont rely on handshakes people will tell you everything and wont keep it. I learned it the hard way
Be open minded
I met enough people who dont want to share with me their portfolio because they are scared that I will steal something from them. Its stupid! Talk to as many people als possible about your investment. Some amazing things can happend. I meet to many great people because of that and with some I share a 5+ years long friendship maybe we dont share the same ideas but I leanred a lot of it and sometimes I made some profit because of it! Be open !
Prediction & graphic lines
When I did my first Investment (it was gold) I read every morning every article about it I could for at least a solid year. Every monring 20 min Thats rouhly 120 hours. Thats time I will never get back. It was wasted time. The news/articels predicted everything. It was a rollercoaster. I believed it in the beginning because it was new to me. It really messed me up and I spend way to much time overthinking. Its fine to see a prediction but the more extreme it is the more it will never happend.
Also the trendlines are mostly worthless. I read so many people talking about the 50 day trendline or the 200 day trendline. It only idicates if a stock goes up or down but people interepte everything into it. “Oh yeah you can see the restience at 12.50 if it will drop below everbody will sell“. The next day it dropped and nothing happend. Dont believe everything in the internet. (lol)
Keep it simple
Dont make it to complicated you can have the best infos and charts and everything in the world and still lose everything. So dont make it to hard for yourself.
THE MOST IMPORTANT ADVICE
No depts
Dont take a credit just because you know a great investment. No matter how much you could earn DO NOT TAKE A CREDIT. This can not only ruin you financily but also your family and your whole life. This is no joke! Make no depts.
DO NOT MAKE FUCKING DEBTS!
My Strategy
It is a mixture of long term and mid-term stock investments. Its very easy I invested in:
Before I buy some
- Royal Dutch because of the high dividend
- Deutsche Bank when the hit nearly a all time low hoping to recover (still hoping ☹ )
- Lufthansa because they bought few airlines and hopefully will grow but its not (thanks Greta !)
- Tesla because they are low and made some good deals for the future. (update, sold it and made 30-35% in 6 weeks)
Am I rich or making a lot of money?! Hell no! But Iam making enough to pay for my holidays and few extras. I am patient enough to sit out bad times. I never sold anything with loose and I want to keep it that way. I like having a clean record.
Thanks for reading and feel free to ask my everything.

IoT Testing !!!

IoT is a whole ecosystem that contains intelligent devices equipped with sensors (sensors) that provide remote control, storage, transmission and security of data. The Internet of Things (IoT) is an innovative solution in various areas such as healthcare, insurance, labor protection, logistics, ecology, etc. To unleash the full potential of using IoT devices, it is necessary to solve many problems related to standards, security, architecture, ecosystem construction, channels and device connection protocols. Today in the world, large organizations such as NIST, IEEE, ISO / IEC, and others make enormous efforts in addressing the issues of standardization, security, and the architecture of developed devices. Analysis of recent scientific research in the field of solving information security issues and data privacy of IoT devices showed positive results, but these methods and approaches are based on traditional methods of network security. The development and application of security mechanisms for IoT devices is a complex and heterogeneous task. In this regard, ensuring information security and the protection of sensitive data, as well as the availability of IoT devices, is the main purpose of writing this article. Given the above, many questions arise related to the security status of IoT devices, namely: What are the current standards and protocols for IoT? What are the requirements for ensuring information security of IoT devices? What security mechanisms do IoT devices have? What methods of testing IoT devices exist? Manufacturers and developers of IoT devices do not pay enough attention to security issues. With the development of cyber-attacks, attack vectors are becoming more sophisticated and aimed at several infrastructure elements at the same time. IoT infrastructure typically includes millions of connected objects and devices that store and share confidential information. Scenarios of theft and fraud, such as hacking and falsifying personal data, pose a serious threat to such IoT devices. Most IoT devices use the public Internet to exchange data, which makes them vulnerable to cyber-attacks. Modern approaches to information security often offer solutions to individual problems, when multi-level approaches offer increased resistance to cyber-attacks.
Challenges of testing IoT devices
To a request to name essential items, many would answer: food, a roof over your head, clothes … With one caveat: this was the case in the last century.
Since then, the species Homo Sapiens has accumulated needs. We need automatic sensors to control the lighting, not just switches, for smart systems to monitor health and car traffic. The list goes on … In general, we can make life easier and better.
Let’s try to figure out how all this Internet of things works before moving on to testing.

The Internet of things (or IoT) is a network that combines many objects: vehicles, home automation, medical equipment, microchips, etc. All these constituent elements accumulate and transmit data. Through this technology, the user controls the devices remotely.

Examples of IoT devices

# 1) Wearable technology: Fitbit Fitness Bracelets and Apple Watch smart watches sync seamlessly with other mobile devices.

IoT – watches and bracelets

Itís easier to collect health information: heart rate, body activity during sleep, etc.
# 2) Infrastructure and development The CitySense app analyzes lighting data online and turns lights on and off automatically. There are applications that control traffic lights or report on the availability of parking lots.
# 3) Health Some health monitoring systems are used in hospitals. The basis of their work is indicative data. These services control the dosage of drugs at different times of the day. For example, the UroSense application monitors the level of fluid in the body and, if necessary, increases this level. And doctors will learn about patient information wirelessly.
Technologies that are present in IoT RFID (Radio Frequency Identification), EPC (Electronic Product Code) NFC (ìNear Field Communicationî) provides two-way communication between devices. This technology is present in smartphones and is used for contactless transactions.
Bluetooth It is widely used in situations where near-field communication is sufficient. Most often present in wearable devices. Z-Wave. Low frequency RF technology. Most often used for home automation, lighting control, etc. WiFi. The most popular network for IoT (file, data and message transfer). IoT Testing Consider an example : a medical system that monitors health status, heart rate, fluid content, and sends reports to healthcare providers. Data is displayed in the system; archives available. And doctors are already deciding whether to take medication for the patient remotely.
IoT architecture
There are several approaches for testing the IoT architecture.
# 1) Usability: It is necessary to provide usability testing of each device. A medical device that monitors your health should be portable.
Sufficiently thought out equipment is needed that would send not only notifications, but also error messages, warnings, etc. The system must have an option that captures events, so that the end user understands. If this is not possible, event information is stored in the database. The ability to process data and exchange tasks between devices is carefully checked. # 2) IoT Security: Data is at the heart of all connected devices. Therefore, unauthorized access during data transfer is not ruled out. From the point of view of software testing, it is necessary to check how secure / encrypted the data is. If there is a UI, you need to check if it is password protected. # 3) Network features: Network connectivity and IoT functionality are critical. After all, we are talking about a system that is used for health purposes. Two main aspects are tested: The presence of a network , the possibility of data transfer (whether jobs are transferred from one device to another without any hitch). The scenario when there is no connection . Regardless of the level of reliability of the system, it is likely that the status of the system will be ìofflineî. If the network is unavailable, employees of the hospital or other organization need to know about it (notifications). Thus, they will be able to monitor the condition of the patient themselves, and not wait for the system to work. On the other hand, in such systems there is usually a mechanism that saves data if the system is offline. That is, data loss is eliminated. # 4) Efficiency: It is necessary to take into account the extent to which the healthcare solution is applicable in specific conditions. In testing, from 2 to 10 patients participate, data is transmitted to 10-20 devices. If the entire hospital is connected to the network, this is already 180-200 patients. That is, there will be more actual data than test data. In addition, it is necessary to test the utility for monitoring the system: current load, power consumption, temperature, etc. # 5) Compatibility testing: This item is always present in the plan for testing the IoT system. The compatibility of different versions of operating systems, browser types and their respective versions, devices of different generations, communication modes [for example, Bluetooth 2.0, 3.0] is extremely important for IoT. # 6) Pilot testing: Pilot testing is a mandatory point of the test plan. Only tests in the laboratory will allow us to conclude that the system is functional. In pilot testing, the number of users is limited. They make manipulations with the application and express their opinion. These comments turn out to be very helpful, they make a reliable application. # 7) Check for compliance: The system, which monitors the state of health, undergoes many compliance checks. It also happens that a software product passes all stages of testing, but fails the final test for compliance [testing is carried out by the regulatory body]. It is more advisable to check for compliance with norms and standards before starting the development cycle. # 8) Testing updates: IoT is a combination of many protocols, devices, operating systems, firmware, hardware, network layers, etc. When an update occurs – be it a system or something else of the above – rigorous regression testing is required. The overall strategy is being amended to avoid the difficulties associated with the upgrade.

IoT testing challengesIoT testing

# 1) Hard / soft IoT is an architecture in which software and hardware components are closely intertwined. Not only software is important, but also hard: sensors, gateways, etc.
Functional testing alone will not be enough to certify the system. All components are interdependent. IoT is much more complicated than simpler systems [only software or only hard].
# 2) Device Interaction Model Components of the network must interact in real time or close to real. All this becomes a single whole – hence the additional difficulties associated with IoT (security, backward compatibility and updates).
# 3) Testing data coming in real time Obtaining this data is extremely difficult. The matter is complicated by the fact that the system, as in the described case, may relate to the health sector.
# 4) UI An IoT network usually consists of different devices that are controlled by different platforms [iOS, Android, Windows, linux]. Testing is possible only on some devices, since testing on all possible devices is almost impossible.
# 5) Network Availability Network connectivity plays an important role in IoT. The data rate is increasing. IoT architecture should be tested under various connection conditions, at different speeds. Virtual network emulators in most cases are used to diversify network load, connectivity, stability, and other elements of load testing . But the evidence is always new scenarios, and the testing team does not know where the difficulties will arise in the future.

IoT Testing ToolsIoT and software

There are many tools that are used in testing IoT systems.
They are classified depending on the purpose:
# 1) Software: Wireshark : An open source tool. Used to monitor traffic in the interface, source / given host address, etc. Tcpdump : This tool does a similar job. The utility does not have a GUI, its interface is the command line. It enables the user to flash TCP / IP and other packets that are transmitted over the network. # 2) Hard: JTAG Dongle: A tool similar to debuggers in PC applications. Allows you to find defects in the code of the target platform and shows the changes step by step. Digital Storage Oscilloscope : checks various events using time stamps, power outages, signal integrity. Software Defined Radio : emulates a transmitter and receiver for various wireless gateways. IoT is an emerging market and many opportunities. In the foreseeable future, the Internet of things will become one of the main areas of work for tester teams. Network devices, smart gadget applications, communication modules – all this plays an important role in the study and evaluation of various services.
Total The approach to testing IoT may vary depending on the specific system / architecture.
Itís difficult to test IoT, but at the same time itís an interesting job, since testers have a good place to swing – there are many devices, protocols and operating systems.
PS You should try out the TAAS format (“tests from the user’s point of view”), and not just fulfill the formal requirements.
—————
Smart watches, baby-sitters, wireless gadgets and devices such as, for example, a portable radio station have long been part of everyday life.
Hackers have already proven that many of these attacks on IoT are possible.
Many people in general first learned about IoT security threats when they heard about the Mirai botnet in September 2016.
According to some estimates, Mirai infected about 2.5 million IoT devices, including printers, routers and cameras connected to the Internet.
The botnetís creators used it to launch distributed denial of service (DDoS) attacks, including an attack on the KrebsonSecurity cybersecurity blog.
In fact, the attackers used all devices infected with Mirai to try to connect to the target site at the same time, in the hope of suppressing the servers and preventing access to the site.
Since Mirai was first published on the news, attackers launched other botnet attacks on IoT, including Reaper and Hajime.
Experts say that such attacks are most likely in the future.
The Internet of Things (IoT) can bring many advantages to modern life, but it also has one huge drawback: security threats.
In its 2018 IOT forecasts, Forroter Research notes: ìSecurity threats are a major concern for companies deploying IoT solutions – in fact, this is the main task of organizations looking to deploy IoT solutions.
However, most firms do not regularly prevent IoT-specific security threats, and business pressure suppresses technical security issues. î
IoT security risks can be even more significant on the consumer side, where people are often unaware of potential threats and what they should do to avoid threats.
A 2017 IoT security survey sponsored by Gemalto Security Provider found that only 14 percent of consumers surveyed consider themselves IoT-aware.
This number is particularly noteworthy because 54 percent of the respondents owned an average of four IoT devices.
And these IoT security threats are not just theoretical.
Hackers and cybercriminals have already found ways to compromise many IoT devices and networks, and experts say that successful attacks are likely to increase.
Forrester predicted: “In 2018, we will see more attacks related to IoT … except that they will increase in scale and loss.”
What types of IoT security threats will enterprises and consumers face in 2018?
Based on historical precedent, here are ten of the most likely types of attacks.
  1. Botnets and DDoS attacks
  2. Remote recording The possibility that attackers can hack IoT devices and record owners without their knowledge is not revealed as a result of the work of hackers, but as a result of the work of the Central Intelligence Agency (CIA).
Documents released by WikiLeaks implied that the spy agency knew about dozens of zero-day exploits for IoT devices, but did not disclose errors, because they hoped to use vulnerabilities to secretly record conversations that would reveal the actions of alleged opponents of America.
Documents pointed to vulnerabilities in smart TVs, as well as on Android and iOS smartphones.
The obvious consequence is that criminals can also exploit these vulnerabilities for their vile purposes.
  1. Spam In January 2014, one of the first known attacks using IoT devices used more than 100,000 Internet-connected devices, including televisions, routers, and at least one smart refrigerator to send 300,000 spam emails per day.
The attackers sent no more than 10 messages from each device, which makes it very difficult to block or determine the location of the incident.
This first attack was not far from the last.
IoT spam attacks continued in the fall with the Linux.ProxyM IoT botnet.
  1. APTs In recent years, advanced persistent threats (APTs) have become a serious concern for security professionals.
APTs are carried out by funded and widespread attackers such as nation states or corporations that launch complex cyberattacks that are difficult to prevent or mitigate.
For example, the Stuxnet worm, which destroyed Iranian nuclear centrifuges and hacking Sony Pictures 2014, was attributed to nation states.
Because the critical infrastructure is connected to the Internet, many experts warn that APTs may launch a power-oriented IoT attack, industrial control systems, or other systems connected to the Internet.
Some even warn that terrorists could launch an attack on iOT, which could harm the global economy.
  1. Ransomware Ransomware has become too common on home PCs and corporate networks. Now experts say that it is only a matter of time before the attackers begin to block smart devices. Security researchers have already demonstrated the ability to install ransomware on smart thermostats. For example, they can raise the temperature to 95 degrees and refuse to return it to its normal state until the owner agrees to pay a ransom in Bitcoins. They can also launch similar attacks on garage doors, vehicles, or even appliances. How much would you pay to unlock your smart coffee pot first thing in the morning?
  2. Data theft Obtaining important data, such as customer names, credit card numbers, social security numbers, and other personal information, is still one of the main goals of cyber attacks.
IoT devices represent a whole new vector of attack for criminals looking for ways to invade corporate or home networks.
For example, if an improperly configured device or IoT sensor is connected to corporate networks, this can give attackers a new way to enter the network and potentially find the valuable data that they need.
  1. Home theft As smart locks and smart garage doors become more commonplace, it is also more likely that cybercriminals can become real thieves.
Home systems that are not properly protected can be vulnerable to criminals with sophisticated tools and software.
Security researchers are unlikely to have shown that itís quite easy to break into a house through smart locks from several different manufacturers, and smart garage doors do not seem to be much safer.
  1. Communication with children One of the most disturbing IoT security stories came from children.
One couple discovered that the stranger not only used his monitor for children to spy on their three-year-old son, this stranger also spoke with his child through the device.
Mother heard an unknown voice: ìWake up, boy, dad is looking for you,î and the child said that he was scared because at night someone was talking to him on an electronic device.
As more and more children’s gadgets and toys connect to the Internet, it seems likely that these frightening scenarios may become more common.
  1. Remote control of a vehicle As vehicles become smarter and more accessible on the Internet, they also become vulnerable to attack.
Hackers have shown that they can take control of a jeep, maximize air conditioning, change the radio station, start the wipers, and ultimately slow down the car.
The news led to the recall of 1.4 million cars, but whitehat researchers, following the original exploit, said they discovered additional vulnerabilities that were not fixed by the Chrysler patch applied to the recalled cars.
Although experts say the automotive industry is doing a great job of ensuring vehicle safety, it is almost certain that attackers will find new vulnerabilities in such smart cars.
  1. Personal attacks Sometimes IoT covers more than just devices – it can also include people who have connected medical devices implanted in their bodies.
An episode of the television series Homeland attempted a murder aimed at an implanted medical device, and former vice president Dick Cheney was so worried about this scenario that he turned off the wireless capabilities on his implanted defibrillator.
This kind of attack has not yet happened in real life, but it remains possible, as many medical devices become part of the IoT.

AMA in the community

Q1:- What is SpockChain & its Current Progress? What are the Problems SpockChain trying to solve?

Ans:- Spock has been launched its mainnet on 8/13 2019, it’s the first public blockchain support Solidity smart contract with PoC consensus. In the last month, we have achieved several goals: 1.launched the mainnet, 2.been listed on 6 exchanges, and also Spock has won the voting competition for free list on MXC. 3. Spockpool is online to help small miners to union their capacity and get share of the mining reward. Spock is building a decentralized application network with PoC consensus, which is a more cost saving, environment friendly solution for blockchain system. Spock is going to release is first smart contract in the following months.

Q2:- What is the Use-case Of Spok Coin In Your Ecosystem? How can Holders & Investors Generate Rewards Using Spock Platform?

Ans:- In Spock Network, People can publish/run the apps on the network, all the dapps running on the network needs SPOK. and besides PoC consensus, Spock also involves the concept of PoS, which is that miners need to stake some coins to mine the coins, if not, the miner cannot get the 100% of the block reward, so in SpockPool, coin holders can lend the coins to the miners, when miners mined the reward, it can share with the coin holders.

Q3:- What is the Need & Importance Of SpockChain project in Blockchain Industry?

Ans:- First of all, I think PoC consensus will be a serious option besides PoW and PoS in future, and there must be a significant project stands for PoC consensus, currently Burst or BHD maybe the one, but these two projects has a common problem is that they do not have ecosystem, they only created a coin with PoC consensus, that’s too simple to today’s blockchain world. Spock will be the star project in this area not only just created a coin with PoC consensus, but also it supports smart contract, Ethereum dapps, games can be easily migrated to Spock network.

Q4:- What are the Milestones SpockChain has achieved from the starting of this project? What are the Long Term Targets?

Ans:- For the first question, I have answered in the previous one. Like launch the mainnet, got investment from Continue Capital and other token funds, IEO/IGO on the several exchanges, got free list on MXC by won the voting competition, released explorer, dashboard, desktop wallet, Android wallet, and SpockPool, all these things above happens in the last month!!! For the short-term goal, Spock is trying to be the Ethereum with PoC consensus, so for the following 6 month to 1 year, Spock will expand the developer community to increase the dapps/tokens on its network. And also the final goal of Spock is to upgrade the consensus not only store the hash value, but also store documents, music, videos, etc. We’re still working on that part.

Segment 2 Questions

Q5:- What are your major goals to archive in the next 3-4 years? Where can we Spockchain ecosystem in this period? What are your plans to expand and gain more adoption?

Ans:- 1. Spreading the Proof of Capacity consensus, let more people know there is another way of mining to gain. 2. Build the developer economy on Spock Network, on Spock Network, not only smart contract, but a new type of tokens will be supported, which is not like the ERC-20, it’s tokens that generated as the block generated, but the developer can define the tokens generation rules, we call them mining-tokens. 3. Search the new way to upgrade the storage network, to finally achieve the goal that the a decentralized storage network can serve the internet users, that would be a totally new future of blockchain world.

Q6:- As a team member of Spockchain, what is your long-term vision about the industry which Spockchain is working at? Are you afraid someday there will be another project with more innovative technology can replace?

Ans:- I think the infrastructure of Blockchain world today has only two main directions: 1. cross chain Technoledge like Cosmos, Polka-dot. 2. Decentralized storage like IPFS. As long as we're heading to the right direction, we won't get a very bad result, even we have failed, but the way we passed through can be borrowed to other projects, there must be some projects success in this area. I feel confident about the project going and what we have done comparing to the other competitors, as currently so many projects claim that they want to be Ethereum in PoC, but none of the has launched the mainnet except SPOCK.

Q7:- Why Spock Network have Chosen Proof of Capacity Consensus Mechanism ? Any advantage over other consensus?

Ans:- Here is the description in the white paper about advantage of PoC:
Environmental protection: When a mining machine is initialized, the mining cost is relatively small, requiring only a small amount of disk access and a small amount of calculations per block.
• Economy: Many PCs have unused disk space. The marginal cost of using these spaces for mining is small, with immediate rewards and can be used for mining. It is not necessary to consider the cost of electricity as a bitcoin mining machine.
• Equality: Today Bitcoin has become the world of Asics mining machines and large mines, and small-scale investors have struggled to participate in the bitcoin mining ecology, while POC-based mining machines are hardly faced with bitcoin-like The mining machine is constantly updating its iterations so that it is completely eliminated.
• “computing power” sharing: BCH is a BTC hard fork chain, so BTC's proprietary mining machine can also dig BCH, but it can't dig BTC and BCH at the same time, and the POC mechanism can make the hard disk for different chains. The spatial "computing power" data structure is consistent, and these "computing power" can be used to dig assets on these chains at the same time.
I think the value of PoC is under-estimated today, that’s why we want to promote the consensus.

Q8:- What are the competitors of Spock Network? How Spock Network is better than their competitors ?

Ans:- In storage domain, they can be: Filecoin/Storj/Sia/Lambda/Filestorm/Yotta
In PoC consensus domain, there are: Burst/BHD/LHD/Boom/Newbi/Disc
In PoC+Smart contract domain, there are: Spock/Galaxy Network/BSN/EHD
Currently, in a completely decentralized blockchain network, there is no such consensus can distribute the coins as the miners contribute the hard disk and network, all these projects take some trade-off to make that happen except File coin, File coin uses Proof of Replication and Proof of Space-time consensus, that may be an option to solve this problem, but its mainnet has not launched, it would take time to achieve that. The Burst, BHD, and other similar projects only uses PoC consensus to created a mining coin, but the usage and scenario are very limited, it’s not year 2013, you can simply create an alt coin and people will buy it. The PoC consensus needs find some usage and scenario to make the network more solid and strong, the smart contract can be the way. As I listed, all the projects have not launched its mainnet except Spock.

Q9:- How Scalable Spock Network have , How many TPS achieved so far ?

Ans:- Spock has its own advantage about improve TPS, because nodes running in the network has much hard disks and network traffic, basically we can increase the size of block header to increase the TPS, and also we're investigating other ways to improve the TPS.

Q10:- Why the name of Project " SPOCK" . What does it signify about your project?

Ans:- Spock is the leading character of Star Trek, we choose the name to inspire the team to keep exploring the possibility of the blockchain world, sand the slogan of Spock is “live long and prosper”, which is also the hope of the team for the project, nowadays, too many fake mining projects out there, Spock wants to show the honesty and integrity by continually showing the code and improving the project.

Q11:- Followed your whitepaper, Spock has a leaderless PoC protocol, does not use a committee or an authority. How this use for? What benefit does it have for Spock?

Ans:- In the consensus level, there is indeed no such organization can change or control it, just like PoW, when the network needs to upgrade its consensus, the community will join the discussion and the dev team will follow the result of it. That's the spirit of Satoshi and all the early blockchain projects.

Q12:- What is the form of Spock mining? What are the conditions for miner application?

Ans:- To mine spock, you can just use normal computer with several hard dist with plotted files, there are tutorials on thehttps://www.spockchain.org

Q13:- What next technology updating after building a decentralized storage data application network in 2021? Will Spock expand to other areas in long term development?

Ans:- I think after the infrastructure is completed that we will focus on the application ecosystem and adoption of the ecosystem, Spock dev team will continue working on the infrastructure and other scenarios/applications to promote the adoption, I think in a very long time, Spock project will only focus on decentralized storage domain.

Q14:- Does your team have a plan to add DAO module into your project since its its effiency on autonomy, decentralization and transparency?

Ans:- Spock will run DAO mode for autonomy, the Spock team is still working on the details of it.

Q15:- What is the role of Smart Contract in Spock Chain? Does your team have a security system to check the operation of whole project?

Ans:- Smart Contract will be the key feature that distinguish Spock and other projects with PoC consensus, Spock leverages lots of work from Ethereum, so Spock is standing on the shoulders of giants, which potential lower-level security risks can be avoid, and we also have a security team to improve the smart contract, like before you submit your smart contract, there is a service to help to analysis the code to help you avoid some common mistakes.

Q16:- What is Spockchain vision and what's your biggest challenges?

Ans:- Spock is trying to be Ethereum with PoC consensus in a short-term, that goal seems to be very promising as everything goes well so far. Spock’s long-term goal is trying to provide a decentralized storage network for all the internet users, that would be challenging from both technical side and business side.

Q17:- Spockchain looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Spockchain to give it the importance it deserves? What are you planning to achieve with your project goal?

Ans:- I think code and time talks, Spock is not a simply ERC-20 token, it’s a mining coin. If you checkout the top 50 projects on CMC, most of them are mining projects, because mining coins are very fair way to distribute the coins. And Spock provides another option for mining, you don’t have to search for low-cost electricity power, you can just set up the mining machines at home to mine the coins. It’s a potential mining way to mine cryptocurrency, if you have mined BTC/ETH, you can have a try about Spock/Burst/BHD, etc.

Q18:- Blockchain projects is not a child play. While creating spok projects, have u for once been discouraged to the extent of wishing to stop since its all about intelligent contract and users poc consensus.

Ans:- Honestly, we do. there is so many hard work to combine the smart contract and poc consensus, but we believe the technology and engineering, and we believe the judgement about the trend of blockchain technology, that's what encourage us to the place we have achieved.

Q19:- How the SpockChain project planning process is ensure? The market needs constant progress of project! How to avoid the spok Project idleness?

Ans:- We're continuously building and expanding the community and miner groups, both online and offline side. currently most miners are from Asia(China mostly),there are only several miners in Europe and US, we do want to spread spok ecosystem across other continents, if anyone in other countries is interested in promoting Spock, please directly contact me!

Q20:- Can anyone run a POC mining and does it require much processing power? Is the cost of POC mining high?

Ans:- Yes, anyone can run a PoC mining, it's electricity power insensitive. the electricity power of each petabytes of a day is only several dolloars, while the cost of a petabytes will be about 30000 dollars.

Q21:- Is POC exploitation cost high? What is it suitable for? What is the number of SPOCK user statistics today? Does SPOCK have a plan to attract users?

Ans:- you can check out the websites, Official website: https://www.spockchain.org Spock Explorer: http://www.spock.network Miner Dashboard: https://dashboard.spock.network

Q22:- What is the function of SPOCK? Are there any benefits to SPOCK holders? How do I earn SPOCK?

Ans:- All the smart contract runs on Spock will cost SPOK, and miners want to mine SPOK will need some amount of SPOCK to stake. You can get the Spock on the exchanges that lists Spock, MXC, Coinex, VB, Bihodl, etc.
Q23:- So What does SPOCK ecosystem include? What all problems SPOCK will solve in Crypto market?
Ans:- Spock is trying to be the Ethereum with PoC consensus, the biggest advantage of PoC consensus is that it saves much electricity than PoW, the “computing power “ is kind of like stored on the hard disk, so the system will be changed to be storage-incentive from computing-incentive., that would change the way of crypto mining, and also Spock introduced the Solidity smart contract in such blockchain system, which make the developers easily migrated their dapps from Ethereum to Spock.
Q24:- How Proof of Capacity Consensus works in SPOCK Chain?
Ans:- The core function about PoC in Spock is just like the PoC consensuse implementation in Burst project, which is the first project uses PoC consensus since year 2014. In high level, the PoC consensus is an algorithm which preprocessing the hash calculation by plotting the whole hard disk with hash values, when generating a new block, the node will scan the hard disk and find the most proper "answer" in the disks and submit to the network, the node submitted the most proper answer will get the mining reward.
Q25:- How Spock and other storage platform i.e. Google drive are different and what benefits you have over them?
Ans:- Basically Spock and Google drive is totally different, as Spock today only stores consensus data. I’d like to talk about the overall differences between decentralized storage and centralized storage services.
Traditional centralized storage platforms generally use cloud storage. Most of the data is stored on a few cloud platforms, which leads to data accumulation and serious centralization problems. There are also problems including higher cost, slower transfer rate, and lower data security. The decentralized storage application platform encrypts and distributes data through a distributed network, meaning that no data other than the data owner can access the data, ensuring security.
And another core feature is the protection of private data, the open decentralized platform can do better, just like the assets of the cryptocurrency, the ownership of the assets represented by the private key, in the decentralized storage platform The private key can represent the disposition and access rights of the data.
Q26:- What do you think is the biggest problem Spock Network will solve which is not solved by other projects yet and why is the problem important to solve?I mean how unique SPOCK Network have?What are the Real world use-cases & utility of SPOK ?
Ans:- 1. I think there are so much projects uses PoC consensus, but all of them are lack of economy, with smart contract feature, Spock will be the first public blockchain support Solidity smart contract and with lower energy cost for running.
2. First of all, the usage of the smart contract will cost SPOK , and the mining policy makes miners need to stake SPOK to mine. and other industry is trying to looking for the adoption of Spock as it's a storage network with smart contract, there is very much possibility we can explore.
Q27:- Will the mining on SPOCK CHAIN Platform Profitablein bear Market? In which form will the output of Mining?
Ans:- The PoC mining is the most anti-bear-marketing mining way I think, you know when BTC comes to 15000$, Bitmain miners S9’s price goes to 4000$, this year, when the BTC prices comes to 3000$, S9’s price is less than 100$. Miners takes all the risk for the price going down, because the manufactory of BTC/BCH miner machines are limited and united. While the miner machines of PoC consensus does not have that problem, because the supplyment of hard disk is very sufficient, and the price is very stable.
Q28:- Why does Spockchain use POC and not POW or POS? Are there advantages of POC compared to POW and POS? There are many projects using POC such as: BHD, BSN, .... Is Spockchain different from these projects?
Ans:- 1. The main issue of PoW is that it’s energy waste and it limits the miners nowadays, people basically cannot mine any PoW coins at home, they have to buy equipments and send them to some place with lower-cost electricity power which makes difficulty to ordinary people. The biggest advantage of PoC is that it save tremendous money on electricity power.
The PoS basically cost nothing to generate new coins, I think it would also be problem for the price, as people get the coins so easy, they may not value it.
2.I have a list about PoC coins (the list is growing..) I do want to share some opinion about all these PoC projects including Spock.
I categorized the projects into two:
PoC consensus only: Burst/BHD/LHD/DISC/Boom/Newbi/Lava
PoC consensus + Smart Contract: Spock/BSN/Galaxy Network/EHD
For the projects in first list, these projects only talks about consensus and coins, but lack of usage and scenarios.
For the second lines, please check out and compare all the projects, none of them have launched the mainnet except SPOCK, while those projects started to mine with ERC-20 tokens.
I think the chanlledge is lack of acknowledge of Proof of Capacity consensus all over the world, the PoC introduce a new way to mine cryptocurrency, currently, Spock has a lot of miners in China, but not much in other places, spreading the consensus takes time. I think code/products shows hoesty and integrity, we have lots of plan to develop the network, while so many projects with similar ideas still runs on ERC-20, with time goes by, people will distinguish that.
Q29:- Currently, what are risks affecting the Spockchain project? In order to develop project in long term and attract investors, which method do you use to manage, minimize the negative impact of risks? I mean that, what are the risks and how do you deal with them?
Ans:- do you mean cheat when mining? First of all, you cannot have fundamental issue on the consensus basis, then if there is some way for smart miners to cheat to gain more rewards, we can update the full node program which can prevent the cheat. I think if that happen, community will support us to update the nodes in the network.
Q30:- How can a cryptocurrency mining algorithm be detected and prevented? What makes them so difficult to detect?
Ans:- According to the stats, 2016-2018, the supply of hard disk is 1.2billion, if we count as average capacity 4T, which is 48,000,000P, while currenlty the largest network with PoC consensus is BHD, which has capacity at about only 1500P.

What Are the Biggest Alleged Crypto Heists and How Much Was Stolen?

What Are the Biggest Alleged Crypto Heists and How Much Was Stolen?
https://preview.redd.it/svrbgh5fcyg31.jpg?width=2000&format=pjpg&auto=webp&s=9d5b11523cdd8873d37becbef5726d68dc821460

As the appeal of cryptocurrency has grown, so has the opportunity for scammers to part naive investors from their money. 2019 has been no exception, with cryptocurrency and blockchain forensics company Ciphertrace dubbing it “the year of the exit scam.”
Exit scams are not a new phenomenon, with a 2018 report conducted by Statis Group revealing over 80% of initial coin offerings (ICOs) in that year to have been fraudulent. Here, Cointelegraph explains exit scams and how to spot them, as well as a look at some of the biggest scams that have been discovered by various researchers.

What are exit scams?

The premise of cryptocurrency is simple, a new ICO launches, claiming to offer lucrative returns for investors. Investors can’t believe their luck and clamor to buy in. The business runs for some time on the back of the invested capital, but, sooner or later, disaster strikes and the company shuts down, often with no explanation.
After a while, it becomes obvious that the company is gone for good, along with the invested funds. The poisoned chalice of crypto’s decentralized nature often means that investors are left in the dark when trying to recoup or trace their pilfered funds.

How to spot an exit scam

Many exit scams have tell-tale signs that investors should look out for. The financial content site Investopedia has a handy list of key characteristics.
First, exit scams often have inconsistent or misleading information about the team behind the project. When scouting potential investment opportunities, investors should scour for information on key members of any ICO.
It’s important to remember that online credibility can be faked by purchasing likes, profiles and followers on social media. Celebrity endorsements with verified accounts could also ring alarm bells for investors. A fake Twitter account purporting to be Elon Musk, with a supposedly verified twitter account, raised over $155,000 as part of a 2018 Bitcoin scam.
Investors should verify the credentials of backers, team leaders and promoters of cryptocurrency projects. Although individuals may seem to be legitimate at first glance, brand new social mediaprofiles and few followers or connections should raise eyebrows.
The most significant characteristic unifying exit scams in cryptocurrency is the promise of a huge return on investment (ROI) — chances are that it’s probably too good to be true. Investors should always look through even the smallest details of what they are required to invest and what the company purports to be able to give back to them.
ICOs usually come with a white paper, setting out the design details of the project along with a business plan and other information. Investors should pursue all available information for ICOs, as any vagueness in the white papers should signal a big red flag.
When investing in an ICO, it’s vital to get an understanding of the business model. Investopdia writes that anything powered by concept alone should be a warning to anyone tempted to buy in. Although cryptocurrency projects can and do launch off the back of technological advances, investors should be wary of projects looking to gather millions of dollars before taking a sober look at the project’s ability to return the investment from the published information.
Heavy promotion of an upcoming ICO can also be a sign of an exit scam. Past scams have employed bloggers to promote via numerous forums. Ads both online and in print media could also be suspicious.

$2.9 billion PlusToken scam could be largest exit scam ever

A 2019 report shared with Cointelegraph by the cryptocurrency and blockchain forensics company Ciphertrace dubbed 2019 the year of the exit scam and highlighted the billions of dollars stolen in multiple scams this year alone.
The report shines a light on what, if confirmed, could be the biggest crypto scam ever, with an estimated loss of around $2.9 billion after Chinese police uncovered an alleged Ponzi schemeinvolving the South Korean wallet provider and exchange PlusToken. Although more is being uncovered about PlusToken, mystery still surrounds the key events.
Ciphertrace reports that the platform has enshrouded several Chinese nationals, the government of Vanuatu, the Chinese police and the company’s co-founders — a South Korean man operating under the alias of “Kim Jung Un” and a Russian known only as “Leo.” The alleged PlusToken scam centers around an app with which the wallet provider claimed investors could invest in PlusToken (PLUS).
According to the report, the firm claimed that the token, based on the Ethereum blockchain, was developed by a major technology company. PlusToken is also said to have falsely stated that it could deliver wallet holders an ROI of between 8% and 16% per month, with a minimum deposit of $500 in crypto assets.
Ciphertrace also reported that no verifiable source of revenue existed other than the proceeds from new membership. Those were onboarded per the traditional method of a Ponzi scheme, which require a constant stream of new investment in order to support its semblance of growth. Investors were incentivized to recommend new users with an invitation, which was the only way to join.
Although this was enough for some members to dismiss the legitimacy of the project outright, Leo, the company’s co-founder, published a press release that claimed he had met with Prince Charles, the future head of the English royal family, providing photos as proof. Ciphertrust reported that it had contacted the Prince Charles Foundation, which confirmed that Leo had indeed attended the event, but would not provide other information about the individual due to European Union General Data Protection Regulation, or GDPR.
PlusToken’s fate was seemingly sealed on June 28, after members of the Chinese police touched down in Vanuatu, detained six people involved with the project and extradited them back to mainland China. Ciphertrace reported that the so-called “PlusToken Six” were either Vanuatu citizens or applying for citizenship at the time of their arrest.
Soon after, PlusToken members found that they were unable to withdraw funds from their accounts. Customers were informed that withdrawals via the app were frozen due to “technical difficulties.” By June 20, the PlusToken app had ceased operations due to purported system maintenance.
For investors, there seems to be no secure lead on the final resting place of the allegedly billions of dollars of stolen funds. The Chinese government has yet to comment. A July 12 post from PlusToken stated that the six Chinese individuals were simply service users and not actually involved with the running of the company itself, stating that users should ignore the rumors and not try to log in until they receive confirmation that the servers are back online.

Pincoin

On April 9, 2018, two ICOs — iFan and Pincoin — operating under the umbrella of company Modern Tech based in Vietnam, went silent after reports outed them as scams that had scalped 32,000 investors out of an alleged $660 million in tokens, according to Tuoi Tre News.
Victims claim that the damages amount to roughly 15 trillion Vietnamese dong ($660 million) in token sales. Angered investors held a demonstration outside Modern Tech’s Ho Chi Minh City headquarters on April 8.
One of the initial characteristics that could have alarmed investors was the fact that Pincoin offered service users bonuses for successfully bringing other people on board. Pincoin did initially pay out cash until January 2018, when the company switched to iFan tokens, TechCrunch reported.
The owner of Modern Tech’s office building said that the company left its offices in March and that no one knew their current whereabouts. The firm left behind only an incomplete website that is now inactive. Modern Tech initially tried to pass itself off as a mere representative of both coins in Vietnam, prior to media reports confirming that seven of its Vietnamese executives were in fact behind the projects.
TechCrunch reported that the ambiguous mission statement from the then-functional site is typical of the vague and jargon-filled copy used by exit scammers:
“The PIN Project is about building an online collaborative consumption platform for global community, base on principles of Sharing Economy, Blockchain Technology, and Crypto Currency”
Financial scam directory Behindmlm released a report in February 2018 that found its buy-in method was typical of an ROI Ponzi scheme. Pincoin’s website is currently down, though iFan’s is still online.

QuadrigaCX — regulators catch on

The death of 30-year old Gerald Cotten shook the crypto world — not only because Cotten was the co-founder and CEO of Canada’s largest cryptocurrency exchange, QuadrigaCX, but also because his control of the passwords and keys to accounts rendered all the assets on the exchange forever inaccessible after his death. Cotten took over $195 million of stolen cryptocurrency with him to the grave.

Commenting on the May 9 Ernst & Young report, Ciphertrace said Cotten had played fast and loose with customer funds for many years in order to support a lavish lifestyle for both himself and his wife. Cotten allegedly exercised complete control over the exchange and used his position to perform “unsupported deposits” — i.e., fabricated transactions not represented by either fiat or cryptocurrency.
Cotten also used significant volumes of customers’ cryptocurrency via transfers from the platform into other exchanges he controlled. As per the EY report, Cotten shifted significant amounts of fiat and cryptocurrency between alias accounts, although less than 1% of these transfers was supported by documentation. Ciphertrace notes that as the admin, Cotten was in a perfect position to hide his fraudulent activities.
In a pattern that may now seem familiar, Cotten used customer funds to pay for QuadrigaCX operating costs after the company suffered liquidity issues due to his reported fraudulent use of user deposits. As QuadrigaCX began to struggle to stay afloat, EY reported that Cotten gambled customer funds in off-platform margin accounts to meet margin calls.
The report also states that Cotten traded unsupported deposits for legitimate funds thereby generating artificial trading markets, abused his position to override Know Your Customer requirements and hoarded all passwords:
“The Monitor understands passwords were held by a single individual, Mr. Cotten and it appears that Quadriga failed to ensure adequate safeguard procedures were in place to transfer passwords and other critical operating data to other Quadriga representatives should a critical event materialize (such as the death of key management personnel).”
As of April 12, EY estimated that Quadriga held around $20.8 million in assets and around $160 million in liabilities. The debts and assets are spread over three subsidiary companies, 0984750 B.C. LTD. (the “Quadriga Estate”), Quadriga Fintech Solutions and Whiteside Capital Corporation. On July 31, the Supreme Court of Nova Scotia approved over $1.6 million in fees for parties seeking remuneration from the exchange, according to court documents.PDF) seen by Cointelegraph.

CFTC action launched after $147 million BTC scheme

On June 18, 2019, the United States Commodity Futures Trading Commission (CFTC) initiated a civil enforcement action against now-defunct Control-Finance Limited for a scheme involving $147 million worth in Bitcoin.
It is alleged that Control-Finance Ltd. defrauded over 1,000 investors by laundering around 22,858 Bitcoin. In mid-September 2017, its website was abruptly taken offline, payments to clients were suspended and advertising content from social media accounts was deleted.
The firm initially said that it would reimburse customers by late 2017. However, the company allegedly began transferring laundered Bitcoin by using the crypto wallet service CoinPayments. According to Ciphertrace’s Q2 2019 Anti-Money Laundering (AML) report, the CFTC complaint charges the company and its founder Benjamin Reynolds with:
“Exploiting public enthusiasm for crypto assets by fraudulently obtaining and misappropriating at least 22,858.22 Bitcoin from more than 1,000 customers through a classic high-yield investment (HYIP) Ponzi scheme called the Control-Finance Affiliate Program.”
Per the CFTC, the company claimed that investors who buy Bitcoin through the firm would be guaranteed daily profits thanks to their team of expert cryptocurrency traders. The complaint also stated that the firm falsely claimed market volatility would ensure funds invested through Control-Finance would result in profit.
The CFTC also alleged that Control-Finance misleadingly promised that it could earn customers a 1.5% ROI daily and 45% monthly. Control-Finance is also reported to have sent partial amounts of new clients’ BTC deposits to other customers, which were disguised as profit from trading, a tactic typical of Ponzi schemes. The legal action seeking civil monetary penalties and permanent trading bans continues.

Co-owner of Bitmarket found shot dead after alleged exit scam

On July 8, the Poland-based exchange Bitmarket shut down, citing liquidity issues. According to Ciphertrace’s Q2 2019 AML report, the shutdown cost users around 2,300 Bitcoin, approximately $23 million. Users attempting to log on to the site were met with the following message:
“We regret to inform you that due to the loss of liquidity, since 08/07/2019, Bitmarket.pl/net was forced to cease its operations. We will inform you about further steps.”
Ciphertrace reports that Bitmarket had a history of partners pulling out. In 2015, the firm lost payment processors CashBill and BlueMedia after the companies' banks requested they end their working relationship with Bitmarket. PKO Bank Polski, Bitmarket’s own bank, also terminated its relationship with the firm only six months after Bank BPH had done so earlier in 2015.
Bitmarket’s two founders, Marcin Aszkiełowicz and Tobiasz Niemiro, have contradicting accounts about the misplaced user funds. Aszkiełowicz claimed that the exchange had been hacked for 600 BTC in 2015, an incident from which the company was unable to recover.
Niemiro, however, claimed that he was not responsible for activities on the exchange. Niemiro also purported to have been told that the company was purchased with a deficit of 600 BTC, which he allegedly repaid with his own money. Niemiro said he could not confirm that his partners had indeed used the money to purchase the 600 BTC.
Two weeks after the interview, Niemiro was found dead in a forest near his home with a gunshot wound to the head, which the police deemed to be self-inflicted. The District Attorney’s Office stated that it is not looking into the involvement of third parties in Niemiro’s death, but are still actively investigating the misappropriation of funds.
