Ⅰ One article to understand Ethereum - ETH2.0, is it worth holding for a long time?

I have been reading information about the London upgrade of ETH these days, let me have a brief chat , in the world of cryptocurrency, whether it is investment institutions, blockchain application developers, mining machine manufacturers, or individual investors, hardware suppliers, game industry practitioners, etc., when it comes to Ethereum, there will be more or less Some understanding.

On the one hand, it depends on the wealth creation effect of the Ethereum token ETH itself. Since the initial issuance in 2014, the return on investment has exceeded 7,400 times.

On the other hand, Ethereum, as the most widely used decentralized application programming platform, has attracted countless developers to develop applications on it. These applications not only generate huge commercial value, but also bring more users to ETH as the DEFI ecology, NFT ecology, and DAO ecology flourish.

As the "London Upgrade Plan" approaches, ETH has once again attracted everyone's attention.

What exactly is Ethereum 2.0? What upgrades are included? How is the progress so far?

What impact will the arrival of Ethereum 2.0 have on the decentralized applications of the existing Ethereum ecosystem?

Is ETH worth continuing to invest? I believe you will make your own judgment after reading it.

If building an application is like building a house, then Ethereum provides modules such as walls, roofs, and floors. Users only need to build the house like building blocks. As a result, the cost and speed of building applications on Ethereum have been greatly improved. The emergence of Ethereum quickly attracted a large number of developers to enter the world of Ethereum to write various decentralized applications, which greatly enriched people's demand for decentralized application scenarios.

Schematic diagram of Ethereum application development model

Ethereum and ETH

Cryptocurrencies in the existing market are only single tokens when blockchain technology is applied in a certain scenario.

Ethereum is no exception. Its full project name is "Next Generation Smart Contract and Decentralized Application Platform", and Ether (Ether) is its The native cryptocurrency, referred to as ETH.

In addition to being used for effective exchange with various types of digital assets, ETH also provides a mechanism to pay transaction fees, which is the GAS fee we now pay when doing on-chain operations. . The emergence of the GAS fee mechanism not only protects applications created on the Ethereum network from being abused by malicious programs, but also because GAS income belongs to miners, allowing more users to participate in the accounting of the Ethereum network and become miners, further Maintained Ethereum network security and ecological development.

Unlike BTC, ETH does not use the SHA256 mining algorithm, preventing the entire mining ecosystem from being dominated by ASIC (Application Specific Integrated Circuit) mining machines. As a result, the systemic risks caused by most of the computing power being controlled by centralized institutions.

Ethereum initially adopted the PoW (Proof of Work) proof-of-work mechanism, and people need to pass proof of work to obtain handling fee returns. We often hear that miners use graphics cards to mine, and what they do is POW proof of work. The more graphics cards and the greater the computing power, the greater the workload and the higher the income.

Currently, the total computing power of the entire Ethereum network is approximately 870.26 TH/s. Compared with the consumer-grade graphics cards we are familiar with, the NVIDIA RTX 3080 graphics card calculates The computing power of the Ethereum network is approximately 92-93 MH/s, which is equivalent to the total computing power of 9.36 million 3080 graphics cards.

The Ethereum white paper clearly mentions that the ledger mechanism of PoW Proof of Work will be upgraded to the ledger mechanism of POS (Proof of Stake) Proof of Stake.

ETH economic model

Unlike the total amount of BTC, which is 21 million, ETH’s There is no upper limit on the total amount, but an additional issuance is added every year based on the amount of ETH in the first pre-sale, and the additional issuance amount is 0.26x (x is the total amount of the sale).

But don’t worry that ETH will continue to inflate indefinitely. In the long run, the number of additional coins issued each year is roughly the same as the number of coins lost each year due to death or carelessness. , ETH’s “money supply growth rate” is approaching zero.

The ETH distribution model includes early buyers, early contribution value, long-termPeriod donations and miner income, the specific distribution ratio is as follows.

Now, 60,102,216 * 0.26 = 15,626,576 ETH will be mined by miners every year. After converting to PoS, the annual ETH output will decrease.

Currently, the total amount of ETH circulating in the market is approximately 116,898,848 pieces, with a total market value of approximately US$275.9 billion.

Development history of Ethereum

1. Border stage (2015): online The first fork was carried out shortly afterwards to adjust the difficulty of future mining. This version is in the experimental stage, and the technology is not yet mature. Initially, only a small number of developers can participate in mining. Smart contracts are only for developers to develop applications, and there is no user participation. The Ethereum network is in its infancy.

Frontier phase ETH price: $1.24.

2. Home stage (2016): The Ethereum mainnet conducted its second fork in March 2016 and released the first stable version . This version is the first mature official version, using 100% PoW proof and introducing a difficulty bomb. With the increase in the number of blockchains, the mining difficulty increases exponentially, the performance of the network is greatly improved, and the Ethereum project has also entered a rapid development stage. growth period. In the "Homeland" version, the famous "The DAO attack" also occurred. Ethereum was hard-forked by the community vote into two chains, Ethereum (ETH) and Ethereum Classic (ETC). Buterin stood on ETH's side. side.

Home Phase ETH Price: $12.50.

3. Urban phase (2017~2019): The development of the city is divided into three phases, and the upgrade is divided into three bifurcations, namely in 2017 “Byzantium” in October, “Constantinople” at the end of February 2019, and “Istanbul” in December 2019. These upgrades mainly improve the writing of smart contracts, improve security, add difficulty bombs, and modify some core architecture to assist in the future transition from proof-of-work to proof-of-stake.

In the urban stage, the Ethereum network has officially shown its power and officially entered the mature stage. Smart contracts allow cryptocurrencies on different chains to trade with each other, ERC-20 is also the standard for token issuance in 2017. Thousands of projects are raising funds on the Ethereum network, which is called "Initial Coin Offering (ICO)". I believe that many old people in the currency circle were attracted by ICO at that time. brought in by the wealth creation effect. By 2019, with the rise of the DeFi ecosystem, financial products have officially become the largest industry on the Ethereum chain.

Metropolis ETH price: $151.06.

4. Quiet phase (2020-2023): Similar to the three-phase development of the city, the quiet phase is currently expected to be divided into three branches: Berlin (completed ), London (coming soon), and the third fork later. The "quiet" stage, also known as "Ethereum 2.0", is the final stage of the project. Ethereum will officially shift from the proof-of-work method to the proof-of-stake method, and develop a second-layer expansion plan to improve the operating efficiency of the entire network.

The quiet phase can be said to be the culmination of the Ethereum network. If the first three phases are just an experimental platform for Ethereum’s vision to be demonstrated, the quiet phase After that, Ethereum will officially become a complete entity. It will not only have complete ecological applications, super-fast processing speed, and the coordinated development of many networks, but also the PoS mechanism will be very energy-saving, which truly represents the symbol of the gradual maturity of blockchain technology.

Tranquility Phase ETH Price: The Berlin phase completed on April 15, 2021, the price on that day was $2,454.

Upcoming London Protocol Upgrade

Ethereum Ecology

Ethereum’s ecological development, subordinate division It can be divided into two major categories: one is the construction of Ethereum network ecological applications, and the other is the construction of Ethereum network expansion. The two integrate with each other and achieve each other. Applications need a more robust and powerful network as a carrier, and the network needs application scenarios with complete functions to serve users.

Let’s talk about the application ecosystem first. We can divide the Ethereum ecosystem into the following categories:

p>

1. Decentralized self-made organization (DAO) ecology

What is a decentralized self-made organization? Let’s take the familiar Bitcoin as an example: Bitcoin’s current market value is more than 700 billion U.S. dollars, ranking ninth in the global asset market value category. However, Bitcoin is not a product released by a certain company, and there is no specific company organization to recruit personnel.Perform maintenance. Everything that exists in Bitcoin originates from the distributed organization spontaneously formed by Bitcoin holders and Bitcoin miners. They plan the development route of Bitcoin through voting and voluntarily participate in maintaining the Bitcoin program and network. This is simply because as long as they have In Bitcoin, everyone is a beneficiary of the construction of the Bitcoin network, and all maintenance stems from their own interests.

The invention and successful operation of Bitcoin broke through the company's business structure that was created by the Dutch and has been popular for more than 400 years, and created a new, seamless An organizational, globally distributed business model, this is DAO.

Going back to Ethereum, Ethereum’s DAO can be written by smart contracts and user-defined application scenarios. To put it simply, we stipulate the program execution conditions and execution scope. In the real world, as long as the set conditions are triggered, the program will automatically execute and run, and all processes will be decentralized and publicly verified on the Ethereum network. No need for Confirmed manually or by any third-party organization.

The Ethereum DAO ecosystem has evolved into many business scenarios. Some charities use DAO to establish an open and transparent donation and usage mechanism, and some venture capital institutions use DAO to establish fairness. Allocated risk funds.

Many projects in the Ethereum ecosystem adopt DAO autonomy. Representative projects include: Uniswap, AAVE, MakerDAO, Compound, Decred, Dash, etc.

2. Decentralized Finance (DEFI) Ecosystem

In the traditional business world Here, if we need to borrow money, save money, or buy stocks of a certain company, or make corporate loans or financing, as long as we are conducting financial activities, we cannot do without dealing with financial institutions such as banks, securities institutions, and accounting firms.

In a decentralized world, the essence of the blockchain is a large open ledger that collects everyone’s transaction records. We can trace back every transaction very easily. For every transaction that has occurred at a wallet address, the balance information of any wallet address can be queried to evaluate the assets in the wallet address.

For example: The country with the most expensive personal loans in the world is India. The mortgage interest rate for young people in India is currently 8.8%, and the highest has ever been 20%. ; Correspondingly, the country with the lowest personal deposit interest rate in the world is Japan, and the Japanese governmentIn order to encourage people to consume, bank deposit interest rates have been negative for a long time. Japanese people not only receive no interest on bank deposits, but also pay custody fees to the bank. In theory, if the Japanese lend their savings to the Indians, both parties can maximize their benefits, but in real life such a scenario is difficult to happen. First, every country has foreign exchange controls. It is not easy for Japanese people to give money to Indians. Second, it is difficult for Japanese people to evaluate the creditworthiness of Indians. There is no unified standard for everyone. In case the loaned money cannot be returned. , we cannot lose profits but still suffer losses.

But in a decentralized world, such things are much simpler.

If an Indian has Bitcoin in his wallet address, we can use smart contracts and the Indian will pledge his Bitcoin into it. According to Bitcoin at the time At the price, the system automatically gives Indians a credit line, and Indians can use this line to borrow money from Japanese people, and the repayment period and interest rate are stipulated. If the Indians default, the contract will automatically deduct the Bitcoins pledged by the Indians, giving priority to protecting Japan's rights. In this way, the Japanese can enjoy the benefits without worrying about safety issues, and the Indians will also have more money as working capital.

This example is a simple application of decentralized finance. In fact, this is the principle of our participation in DEFI mining and pledge financial management - of course the actual application of the algorithm The scene is much more complicated.

DEFI can be divided into many tracks according to different scenarios, such as stable coins, oracles, AMM exchanges, derivatives, aggregators, etc.

Representative projects of DEFI include: Dai, Augur, Chainlink, WBTC, 0x, Balance, Liquidity, etc.

3. Non-Fungible Token (NFT) Ecology

World Famous Paintings "Mona Lisa", only Leonardo da Vinci's original version can be displayed in the Louvre Museum in France. Even if modern technology can reproduce it with extremely fine details, the imitations do not have the collection value of the original version.

This is the application scenario of NFT. NFTs are tokens that we can use to represent ownership of unique items. They allow us to uniquely tokenize real-life things like art, collectibles, and even real estate. Although the files (works) themselves can be copied infinitely, the tokens representing them can be tracked on the chain and used for purchase.Home provides proof of ownership.

Compared with the dual delivery of physical copyright and property rights in reality, NFT only requires the delivery of the unique token describing the item. NFT works are often stored in distributed storage networks such as IPFS. They can be taken at any time and will never be lost. In addition, the delivery is simple and convenient, and soon attracted a large number of players and investors to collect and resell. The emergence of NFT also provides artists with a new revenue model.

Similar to DEFI ecology, NFT ecology has also produced different tracks according to different application scenarios. Currently, the more popular tracks include NFT trading platform, NFT game platform, NFT art platform, a financial platform that combines NFT and DEFI.

Representative NFT projects include: CryptoKitties, CryptoPunks, Meebits, Opensea, Rally, Axie Infinity, Enjin Coin, The Sandbox, etc.

4. Standard Token Protocol (ERC-20) Ecology

and NFT Non-fungible tokens correspond to fungible tokens. For example, the RMB we use is a homogeneous token. We can use RMB for value exchange. Even if the serial numbers are different, its value will not be affected. If the denomination is the same, different banknote serial numbers will make no difference to the holder.

BTC, ETH and all the cryptocurrencies we are familiar with are fungible tokens. There is no difference between one Bitcoin and another Bitcoin of the same type, with the same specifications and uniformity. In a transaction, it is only necessary to pay attention to the number of tokens handed over, whose value may change depending on the time interval of the exchange, but its essence does not change.

Ethereum’s ERC-20 is the standard protocol that defines this kind of token. Anyone can use the ERC-20 protocol and publish it through a few lines of code. Own cryptocurrency on the Ethereum network.

Currently, there are millions of token types running on the Ethereum network. Most of the projects mentioned above have also been released on the Ethereum network. Own fungible token.

Representative projects of ERC-20 are: USDT, USDC, WBTC etc.

Ethereum network scalability

Let’s first introduce a concept: blockchain The impossible triangle means that no matter what method we use, we cannot achieve scalability, decentralization, and security at the same time. We can only get two of the three.

This is actually easy to understand. If we want to decentralize and secure, we need more nodes to participate in the network for verification, which will lead to an increase in the number of verifiers. Network efficiency is reduced and scalability is reduced. Network performance construction is to find a balance between the three.

Using data as an example, Bitcoin can currently handle 7 transfers/second, Ethereum can handle 25 transfers/second, and VISA can handle an average of 4,500 transfers/second. The peak value reaches tens of thousands of transactions per second. This difference in business processing capabilities can be simply understood as the "throughput" gap. If you want to improve throughput, you need to expand the business processing capabilities of the blockchain, which is called scalability.

According to different optimization methods, Ethereum network performance expansion solutions can be divided into:

1. Layer 1 on-chain extension, an extension solution where all transactions are retained on Ethereum, with higher security.

The essence of on-chain expansion is to improve the Ethereum main chain itself, so that the entire system has higher scalability and operating efficiency. There are two general methods, either changing the consensus protocol, for example, ETH will change from PoW to PoS; or using sharding technology and optimization methods to make the network more efficient.

2. Layer 2 off-chain expansion, layering solutions for each scenario separately on top of the Ethereum protocol, with better scalability.

Off-chain expansion can be understood as taking calculations, transactions and other business processing scenarios outside the Ethereum main chain for calculation, and finally transmitting the calculated results back to the main chain. Chain, the main chain only reflects the final result without caring about the process. In this way, no matter how complex the application is, it will not have an impact on the main chain.

We do not need to understand the specific technical implementation, we only need to know: Compared with the Layer 1 solution, the Layer 2 solution network will not interfere with the underlying blockchain protocol. It can take on most of the calculation work for Layer 1, thereby reducingThe burden on the main network improves network business processing efficiency, which is currently recognized as a better expansion solution.

Ethereum 2.0

Finally talking about Ethereum 2.0, back to the topic.

By looking back at the development history of Ethereum, Ethereum 2.0 is not a new project. It is just the last stage of the development process of Ethereum. It will be dominated by the entire Ethereum Multiple teams in the ecosystem work together to make Ethereum more scalable, secure and sustainable, and eventually become mainstream and serve all mankind.

ETH2 construction goals:

1. More scalable. Supports 1000 transactions per second to make the application faster and cheaper to use.

2. More secure. Ethereum has become more secure against all forms of attacks.

3. More sustainable. Improve network performance while reducing energy consumption and better protecting the environment.

The most important change is that ETH2 will upgrade from the PoW (Proof of Work) proof-of-work mechanism used by ETH1 to the POS (Proof of Stake) proof-of-stake mechanism. . Instead of using computing power as a verification method, the amount of pledged cryptocurrency is used as a verification method. Miners can mine without a graphics card, which not only saves time and electricity costs, but also improves the utilization of ETH, which is very similar to earning interest by depositing money in a bank.

The main technology used by ETH2 is sharding and layering technology to expand the entire network.

The ETH2 upgrade will be divided into three phases:

1. Phase 0 (Ongoing): Creation and merging of the beacon chain. The beacon chain is the main chain of ETH2, just like the human brain, and is the basis for ETH2 to operate.

2. Phase 1 (expected to be 2022): Creation and application of shard chains. When the merger of the beacon chain and ETH1 is completed, it will enter the development stage of the shard chain. The shard chain can be understood as the ETH2 mainThe entire block of data in the chain is split and stored according to certain rules, and a new chain is created separately to share the data pressure on the main chain. The current plan is to establish 64 shard chains.

For example, from Beijing to Shanghai, the original means of transportation was only one highway, and all vehicles needed to run on it, which would make it very crowded; now Through sharding technology, more modes of transportation such as high-speed trains and airplanes are available, and the diverted vehicles arrive at the same time faster. This is the role of the sharding chain.

Schematic diagram of the interaction between shard chain and main chain

3. Phase 2 (expected to be 2023): Integration of the entire network functions. At this stage, the functions of the entire system begin to be fully integrated, the functions of the shard chain will become more powerful, and new processing mechanisms will begin to support the creation of accounts, smart contracts, development tools, new ecological applications, etc.

This stage is the final form of the Ethereum network. Network performance has been comprehensively improved and ecological applications have exploded. But to serve all mankind, ETH2’s 1,000 transaction efficiency per second is obviously far from enough, and Ethereum will continue to optimize for its goals.

What impact does ETH2 have on everyone?

1. For Ethereum ecosystem developers. When deploying an application, ETH2 needs to choose which shard network the application will be deployed on. The reason for this difference is that cross-shard communication is not synchronized, which means that developers need to make different combinations according to their own development plans.

2. For ETH holders. The data of ETH2 and ETH1 are completely synchronized, and the tokens will not change. You can continue to use your current wallet address to hold ETH.

3. For miners. Although PoW and PoS will continue to exist in parallel for some time, it is expected that the output of PoW mining machines will be less and less, and investment in PoW mining machines should begin to be reduced and start to shift to the PoS mechanism.

4. For users. ETH2 is faster, has lower transaction fees, and the network experience will be very good. The only thing worth noting is that since Dapps are deployed on different sharded networks, you may need to manually select the application’s network options.

Is ETH worth investing in?

ETH is the benchmark for markets other than BTC. A clear understanding of ETH2 is very helpful for us to understand other blockchain projects and the secondary market.

Let’s briefly summarize a few points:

1. Through Ethereum projects From the analysis, we can clearly see that after Bitcoin, the development history of the Ethereum project is the development history of the current blockchain application ecosystem. Regardless of DEFI ecology, NFT ecology, DAO ecology or token, contract, and protocol ecology, it was actually foreseen when Ethereum released the white paper, and the projects that emerged later were all verified around Ethereum.

2. Among the co-founders of Ethereum, only Buterin is still contributing to the cause of Ethereum, but this does not affect the prosperity and development of Ethereum . The initial team of Ethereum just created it, and subsequent development is the result of the joint efforts of the community, developers, miners and users. The current Ethereum is no longer the thinking of one person, it is the joint crystallization of all Ethereum ecological participants. It belongs to all mankind.

3. Ethereum has been developing along the established development trajectory in the past few years, although there was a crisis midway and Ethereum was "dead" Hundreds of times, Ethereum has still developed tenaciously and has a prosperous ecosystem. It will take two or three years for ETH2 to be implemented, and there are many variables in the process, such as other public chains taking the lead. However, it is foreseeable that Ethereum after ETH2 will be more robust.

4. Do not hold on to any false propositions that BTC will die and the blockchain industry will disappear. BTC and ETH allow us to see the existence of a new unorganized business model that breaks through the original company organizational structure. This business model is obviously more in line with the development needs of this era, no matter whether the project initiating team is present or not, no matter what the governments of various countries do Suppression, as long as technology contributes to mankind, it will be maintained by people's voluntary organizations. Blockchain technology is a revolution.

5. With the launch of ETH2, the parallel PoW rewards and PoS rewards in the short term may cause the total inflation rate of ETH to surge in the short term. In the long term, the inflation rate of ETH will remain unchanged. maintain balance. Coupled with ETH's own ecology and application scenarios, ETH is worth investing in. Currently, there is no possibility of other public chains replacing the Ethereum public chain. The launch of ETH2 will even cause a "siphon effect" to other public chains. The chain is unified.

Ⅱ What is Ethereum/Ethereum ETH

Ethereum (English: Ethereum) is an open source A public blockchain platform with smart contract capabilities. It provides a decentralized virtual machine (called the Ethereum Virtual Machine) through its dedicated cryptocurrency Ether (also known as "Ether") to process peer-to-peer contracts.

The token on the Fang blockchain is called Ether, code is ETH, and can be traded on the foreign exchange market of many cryptocurrencies. It is also used on Ethereum to pay transaction fees and Media for computing services.

The concept of Ethereum was first proposed by programmer Vitalik Buterin between 2013 and 2014, inspired by Bitcoin. It roughly means "the next generation of cryptocurrency and decentralized application platform" and was approved by ICO in 2014. Crowdfunding was able to take off. As of February 2018, Ethereum is the second-largest cryptocurrency by market capitalization, after Bitcoin.

Information expansion:

Ethereum was originally proposed by Vitalik Buterin in 2013. Vitalik was originally a programmer involved in the Bitcoin community. He once suggested to the Bitcoin core developers that the Bitcoin platform should have a more complete programming language for people to develop programs, but he did not get their consent, so he decided to develop a new one. platform for this purpose. Buterin believes that many programs can use principles similar to Bitcoin to achieve further development. Buterin wrote the "Ethereum White Paper" in 2013, outlining the goals of building decentralized programs. Then in 2014, development funds were obtained through online public fundraising, and investors used Bitcoin to purchase Ethereum from the foundation.

The Ethereum program was originally developed by Ethereum Switzerland GmbH, a company in Switzerland, and was later transferred to a non-profit organization, the Ethereum Foundation.

Ⅲ What are the current problems with Ethereum (eth) in the blockchain?

What are the current problems with Ethereum (eth) in the blockchain?
The Ethereum blockchain currently exposes three major problems, which its founder Vitalik
Buterin has been unable to explain for a long time. The first is the overall low performance and TPS of the Ethereum blockchain; the second is the lack of isolation of resources. The CryptoKitties virtual cat incident once occupied
20%
of the entire Ethereum traffic, directly causing The inability of Ethereum network users to carry out timely transactions is the biggest pain point of non-isolation of resources; the third problem lies in the reflection of Ethereum’s governance structure. Blockchain is a decentralized distributed ledger. Ethereum has been, the founder team has led the development of its network, and the overly centralized governance model has caused the current Ethereum to have forks such as ETH, ETC, and ETF, and the Ethereum community is currently in a state of fragmented governance. In the view of "aelf" founder and CEO Ma Haobo, the various shortcomings currently occurring in the Ethereum network are unacceptable. Therefore, the positioning of "aelf" was born to benchmark the next generation of decentralized underlying computing platform of Ethereum, focusing on solving the current problems of insufficient performance, lack of resource isolation, and governance structure of Ethereum.

IV Top Ten Blockchain Mining Apps

The ranking of mobile mining apps is as follows:

1. ETH mobile mining. ETH mobile mining is a software that allows you to make money through mobile mining. Users can trade with confidence in this software. All transaction information is open and transparent, and the latest monetary policies can be seen every day.

2. HBC environmental protection chain. HBC Environmental Chain is a very easy-to-use investment and financial management app. Users can redeem environmental coins by completing mining tasks, and the mining gameplay provided here is very simple.

3. Fire brush horizon mining. Fire Brush Vision is a new blockchain money-making platform, where users can directly receive tasks and complete tasks to obtain rewards. There is no need for any investment or energy, as long as they use their spare time to purchase mining machines. That's it.

4. ABEL trading platform. A professional mobile phone mining software, users can easily obtain a variety of digital currencies here, and can also conduct various digital currency transactions here at any time.

5. Secoin Star Ecology. A very easy-to-use mobile mining software that provides users with a very convenient and easy-to-use mining machine. They only need to use some daily rest time to obtain a variety of digital currencies.

Mobile mining is very simple. Just download the APP and register an account. The ways to obtain rewards are similar. If you want to use this mobile mining APP and increase your computing power, you must use facial recognition, Alipay, and Taobao authorization. , Xuexin.com authorization, operator authorization, JD authorization, binding GXS wallet, backup wallet, inviting friends, and checking in online every day.

Possible disadvantages of mobile phone mining:

1. Stealing user privacy. Some apps pretend to be mining, but are actually collecting user information and C-side traffic, which may cause problems such as user information leakage.

2. Greatly shorten the life of mobile phones. For mobile phones with mining systems installed, apps quickly drain battery power, generate excessive heat, or put unnecessary pressure on device resources.

3. The most important thing is that mobile phone mining is actually mining for candy, and mainstream coins cannot be mined. It is difficult to achieve the technology of mining mainstream coins with mobile phones. Nowadays, mainstream coins such as Bitcoin and Ethereum cannot be mined with the computing power of mobile phones.

IV What is eth

eth is the abbreviation of Ethereum, Ethereum blockThe token on the chain is called Ethereum, code is ETH, and can be traded on the foreign exchange market of many cryptocurrencies. It is also the medium used to pay transaction fees and computing service fees on Ethereum.

Ethereum is an open source public blockchain platform with smart contract functions. Provides a decentralized virtual machine to process peer-to-peer contracts through its dedicated cryptocurrency Ethereum.

The concept of Ethereum was first proposed by a programmer between 2013 and 2014 after being inspired by Bitcoin. It roughly means "the next generation of cryptocurrency and decentralized application platform" and was launched through ICO in 2014. Crowdfunding was able to take off.

VI Is How to Make Money with Blockchain a Scam?

It is not a scam. Generally speaking, the blockchain is still in its infancy, and many projects have not yet been implemented. Only those who respect the law of growth can Only by cultivating it step by step under certain conditions can it gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How blockchain and digital currency will develop in the future depends on the values ​​​​and civilization of the controller.
Blockchain can allow you to make money in this industry, but it can also make you bankrupt. Therefore, I would like to remind users that they need to be cautious when investing. Don’t let yourself get involved without making money, and the gain outweighs the loss. There are also many blockchain scams. We must also be more vigilant to avoid being deceived and causing unnecessary economic losses.
Expand information
Pre-loan stage
Blockchain technology can first be applied to the logistics supply chain to help banks and other lending institutions more comprehensively and accurately grasp the real main business, transaction background, and financing of small and micro enterprises. Downstream affiliated enterprises, as well as their negotiating position in the supply chain, product sales, rhythm and path of payment, etc., on the one hand, help more asset-light, high-growth and high-quality enterprises obtain financing support through transaction bills, logistics documents, etc. On the one hand, it prevents problematic enterprises from falsifying their business background and capital needs to obtain loans.
In addition, blockchain can also be applied to the provident fund interconnection to help banks understand the actual payment status of social security, provident fund, etc. of shareholders, executives, and ordinary employees of borrowing companies, so as to reasonably evaluate the size of the company's personnel and operating conditions, and provide credit and loans. Provide sufficient basis for approval decisions.
Loan stage
Blockchain technology can be applied to corporate loan information review and mortgage and pledge review to help banks improve approval efficiency and ensure approval quality. In the financing process of enterprises, especially small and micro enterprises, they often need to provide contracts and other necessary materials. Paper-based contracts with multiple signatures and seals are not only inefficient, but also have a series of problems such as forgery, alteration, and false signatures, which bring problems to bank approval. Greater counterfeiting, fraud and credit risks.
With the support of blockchain technology, relevant real-name information subjects, orders and ordering processes, electronic contracts, agreement signing processes, subsequent supplementary agreements, and photo materials can be preserved in real time, and all stored certificates cannot be tampered with. Ensure the bank’s rapid certification and approval, and ensure that when disputes arise,Efficient solution. In addition to traditional real estate, other assets owned by enterprises and business owners, including bank financing and other financial assets, can also be used for transfer and pledge, becoming a qualified basis for credit enhancement that can be accepted by banks, improving the availability and immediacy of corporate credit. .
Post-loan stage
Blockchain technology can be applied to the timely assessment of an enterprise's production and operation status and ability to perform repayments, helping banks to effectively grasp credit risks and adjust post-loan risk control strategies at any time. In the past business practice, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of the company's operations in warehousing and exiting on the market value of the remaining mortgages and pledges. The ability to control new loan types such as warehouse receipt pledges is relatively low.
After switching to digital warehouse receipts supported by blockchain technology, product quality, quantity, specifications, photos and other information can be completely and standardized on the chain, authenticity and traceability are fully guaranteed, and banks can technically prevent Enterprises and warehousing institutions fabricate warehouse receipts and inconsistencies between warehouse receipts and warehouse entry and exit information to ensure that post-loan management is effective. In addition, information such as factory buildings and office building leasing of borrowing companies can also be fully shared with banks, upstream and downstream enterprises and other intermediary service agencies through blockchain technology, minimizing the risk of money being lost and other issues such as "people leaving the building empty".

Ⅶ Has the era of blockchain begun or has it ended? Which projects have long-term significance

First of all, what is blockchain? Nowadays, all major mainstream media are positioning blockchain technology as a technology. In fact, I have a different opinion. I think blockchain is more like a more effective solution to credit problems.

We all know that there are currently several types of credit systems in the world: First, based on morality, relying on moral bottom-line constraints to solve credit problems. Second, based on faith, I believe that God’s arrangements are absolutely fair. Third, the banking system is based on the government. As long as the government of each country exists, the numbers in the bank where people's money is located are valuable and can be used as a medium of commodity exchange. When you shop, the transaction amount will be held in custody on a third-party platform. Only after the transaction is successful can the seller get the amount paid by the buyer, based on the credit guarantee of the banking system.

After the emergence of blockchain, there is another cornerstone of the credit system in the world---algorithm. The word algorithm originates from a concept in the computer world. The characteristic of an algorithm is consistency. Regardless of time and place, as long as the input is determined and the algorithm is processed, the output will be determined. This is the basic definition of the consistency of the algorithm. Blockchain is a new credit system developed based on this characteristic.

Ⅸ How does blockchain mining make money

The principle of making money by mining: PoW and mining.

In the beginning, Bitcoin could be mined using graphics cards, but in 2013, it was no longer possible to mine Bitcoin BTC using general-purpose computing programs for graphics cards. Bitcoins are now all mined using ASIC mining machines. ".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the history of Litecoin mining using graphics cards. The current digital currencies that graphics cards can "mine" are Ethereum ETH, Ethereum Classic ETC, and Zcash Zerocoin ZEC.

Graphics card "mining" is not a profitable business, in fact, the earlier you start, the higher the income will be, and the income will decrease as more miners and graphics cards are added.

To put it bluntly, buying a high-priced graphics card to enter "mining" will definitely kill you. Purchasing a professional mining machine is a more cost-effective choice. Nowadays, the essential tool for personal mining is a mining pool. The function of a mining pool is to gather a large number of mining machine computing power to increase your chances of mining coins. At the same time, the coins you can mine in the future are evenly distributed to your account in advance.

Take Bitcoin as an example. If the entire Bitcoin network now generates a block every 10 minutes, this block contains 25 Bitcoins. Assuming that there are 10,000 people in the world participating in mining, then within these 10 minutes, only one lucky person will take away the 25 Bitcoins.

Others have nothing to gain. The principle of the mining pool is that everyone forms a team to mine and allocate according to the agreed distribution method, so that the miners' mining returns tend to be stable and the miners' risks are reduced.

In order to enhance the cost performance, you can also purchase some practical mining machines like Wanke Cloud, which can be used as ordinary hardware products and can also be used for mining, killing two birds with one stone.

(9) Snowball Blockchain eth Crystal Extended Reading

There are several core operating cores of blockchain transactions and digital currencies:

The transaction network connected by decentralized databases is called the blockchain. All our clients (including mining machines) keep accounts together, confirm transfer transactions, and issue a certain amount of digital currency according to time.

Because the winner takes all, small and medium-sized retail miners have to unite to form a "mining pool" and record the cumulative workload in Shares. The higher the joint computing power, the greater the probability that the mining pool consortium will find the digital currency first. Large, increase the probability of finding newly issued digital currencies, and divide the mined digital currencies. This is called the PoW workload proof mechanism.
