❶ Cryptocurrencies in 2030: 5 Key Trends to Watch -

Since the advent of Bitcoin in 2009, the concept of cryptocurrency has expanded tremendously. The crypto space has seen an explosion of new companies coupled with a near-frenzy of public interest, and of course its underlying blockchain technology has improved significantly in more than a decade.

Many people have started to believe in and use cryptocurrencies in their daily lives. By 2030, Deutsche Bank expects there to be 200 million Bitcoin users in the public sector. The mass adoption scenario for crypto enthusiasts is now closer to reality than before. Even during the Covid-19 outbreak, many cryptocurrencies such as Bitcoin have performed quite well compared to financial markets.

The rise of blockchain technology

The use of blockchain technology is growing exponentially. Although DLT technology originated in the world of cryptocurrency, it is already being used in a wide range of other industries, including medicine, finance, and education.

It all comes down to trust and the immutability of data linked together. Spend less money because there is no middleman. But can these characteristics prolong the industry's growth?

Looking at today’s blockchain advancements, we present five predictions for the future development of the technology and what it will look like in 2030.

“Cryptocurrency” is a term that was once understood only by a small group of people and is now a household word. We predict that the value of cryptocurrencies will rise to $7 billion by 2030, more than three times its current market cap of $2 billion. It would be foolish for investors, businesses, and brands alike to ignore the growing crypto wave for too long.

These details are critical to understanding general consumer attitudes and predicting consumer behavior regarding cryptocurrencies in a highly uncertain future.

Governments can use virtual currencies with the help of blockchain. Governments will have to find a way to integrate some virtual currencies to keep up with current trends and participate in the economic growth that will follow.

We already have examples such as digital currencies of various countries and Petromoneda, backed by Venezuela’s oil and mineral resources, that have developed their own digital currencies.

Over time, the use of price-stabilizing tokens governed by monetary rules and backed by collateral will begin to gain momentum. Governments that have had less luck with cryptocurrency creation may turn to stablecoins.

Global supply chains can benefit greatly from the use of blockchain technology. Current global trade is characterized by disjointed and unreliable corporate relationships.

Gray markets such as medical devices, pharmaceuticals, clothing, automotive parts, and food supplies can be a source of life-threatening counterfeit products that kill many people every year.

Therefore, it is expected that the majority of global trade will be conducted using blockchain technology. Before this can be achieved, blockchain technology needs to do several things.

This will allow cryptocurrencies to grow in the ecosystem, thereby promoting economic growth and improving conditions and standards based on trust, immutability and transparency.

Thanks to the widespread tokenization possible through the use of blockchain technology, what was previously only available to those with significant financial resources can now be made available to the public. Luxury hotels are an example of an asset that requires significant capital and upfront risk to acquire.

When huge assets are tokenized, everyone can now own a portion of the income-generating assets. Tokenization is becoming a reality at every level, as evidenced by NBA players converting their contracts into digital tokens.

With the rapid development of blockchain technology, some exciting new things may appear in ten years. However, in the long term, it is feasible that blockchain will grow significantly due to the work of various developer groups.

Directed Acyclic Graphs (DAGs) have been considered as an alternative to blockchain. Faster transactions, no need for mining, and more are considered some of its major advantages over blockchain. We’ve already seen some calling them the future of blockchain technology. In the future, there may be better options for consumers than we currently imagine. Time will prove everything.

A truly immutable ID system that claims to eradicate identity theft, and blockchain voting that could even prevent voter fraud are two of the more interesting blockchain applications. From this vantage point, 2030 looks exciting.

❷ Is mining necessary for blockchain?

Mining is not necessary for blockchain. There are many kinds of proof mechanisms, which are not necessarily necessary. To mine.
Blockchain is a
new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
European Crowdfunding is also a blockchain crowdfunding platform developed based on blockchain. Each crowdfunding project will issue a digital currency as an asset certificate, but this digital currency does not necessarily need to be mined. mine.

❸ Blockchain, 4 types, how much do you know

——Hello, I am mentality, focusing on sharing my understanding of blockchain and investment thinking. hope this helps.

Blockchain According to different usage needs and scenarios, blockchainIt is divided into 4 types: public chain, alliance chain, private chain and hybrid chain.

1. Public chain

Public chain means that anyone at any node in the world and at any geographical location can enter the system to read data, send transactions, and compete. Blockchain that participates in consensus such as accounting. No institution or individual can tamper with the data in it, so the public chain is completely decentralized.

Bitcoin and Ethereum are both representatives of public chains. Public chains generally encourage participants to compete for accounting (i.e. mining) by issuing tokens to ensure data security and consensus updates.

Bitcoin generates one block every 10 minutes on average, and its POW mechanism is difficult to shorten the block time. The POS mechanism can shorten the block time relatively speaking, but it is more likely to cause forks. So the transaction needs to wait for more confirmations before it is considered safe.

It is generally believed that a block in Bitcoin is secure enough after 6 confirmations, which takes about an hour. Such a confirmation speed is difficult to meet commercial-level applications. Therefore, public chains such as ETH and EOS that support more writing speeds are constantly developing.

2. Alliance chain

Alliance chain refers to a blockchain that is jointly participated and managed by several institutions, with each institution running N nodes.

The data of the alliance chain only allows different institutions in the system to read, write and trade. The PKI-based identity management system transactions or proposals are initiated through digital certificates and are verified by the joint signature of the participants. A consensus is reached, so there is no need for proof of work (POW), and there is no digital currency (token), which improves the efficiency of transaction completion and saves a lot of computing costs (computing hardware investment and electricity energy consumption).

Normally, nodes participating in the alliance chain will be divided into different read and write permissions, which can support more than 1,000 data writes per second.

3. Private chain

Unlike the public chain, which is completely decentralized, the private chain’s access rights are controlled by an organization, and the participation qualifications of each node are controlled by the organization. Authorization control.

Since the participating nodes are limited and controllable, private chains often have fast processing speeds and can support more than 1,000 data writes per second, while reducing the transaction costs of internal nodes.

Nodes can participate under real names and therefore have financial attributes to confirm identity. The value of the private chain is mainly to provide a safe, traceable, non-tamperable, and automatically executed computing platform, which can prevent both internal and external security attacks or tampering of data, which is difficult to achieve in traditional systems.

The application scenarios of private chains are generally within the enterprise, such as inventory management of branches, summary statistics of data from various places, etc. It can also be used in governmentGovernment budgets and implementation are areas that can be subject to public scrutiny. Large financial groups are also currently inclined to use private chain technology.

4. Hybrid chain

When the respective advantages of public and private chains are combined, a hybrid chain will appear. The development of hybrid chains is difficult, but the prospects are broad.

In the future market, there will definitely be giant companies that develop underlying technologies and protocols. These giant companies will set up public chains, private chains or alliance chains for different purposes, based on performance and security. and the different needs of application scenarios, and then grafted on applications in different industries. For example, a communication public chain that supports high concurrency, a payment alliance chain that focuses on security, etc.

(Thanks for reading)

A like and a follow are the greatest support for me. See you tomorrow.

❹ After various places have banned Bitcoin and Ethereum "mining", NFT blockchain will be the next step

Although China bans cryptocurrency transactions and "mining", The exploration of blockchain technology continues. At the just-concluded World Artificial Intelligence Conference, Da Hongfei, founder and CEO of Distribution Technology, said in an interview with China Business News that “the manageability of blockchain” is a recent focus. The current scale and growth rate of the global public chain market is much higher than that of the alliance chain business. However, public chains have many limitations, such as illegal crimes, hacker theft, network risks, regulatory obstruction, etc., and cause huge irreparable losses. Therefore, how to increase the manageability of blockchain will be an important issue for blockchain to become mainstream.

The currency circle has been very unstable in the past two months. On May 21, the Financial Stability and Development Committee of the State Council issued a document stating "Crack down on Bitcoin mining and trading activities." On May 25, the Inner Mongolia Development and Reform Commission issued eight measures (draft for comments) to combat and punish virtual currency “mining”. On June 9, the Qinghai Provincial Department of Industry and Information Technology issued the “About Mining of Virtual Currencies” Notice on Cleaning up and Rectifying the Project", and cleaning up and rectifying the relevant virtual currency mining/mining activities.

On June 18, the Sichuan Provincial Development and Reform Commission issued the "Notice of the Energy Bureau on Cleaning up and Shutting Down Virtual Currency "Mining" Projects. For virtual currency mining/mining, the relevant power in Sichuan Enterprises need to complete the screening, cleaning and shutdown work before June 20.

❺ I want to participate in digital currency transactions, do you have any good suggestions?

If you want to participate in digital currency transactions, you must understand the digital currency ecosystem.

Digital currency exchange

It can be said that digital currency exchanges are the most important group in the entire industry.into parts. Digital currency exchanges provide investors and traders with financial channels for buying and selling digital currencies. At the same time, the trading activities of the exchanges determine the current prices of many digital assets.

According to CoinMarketCap, the capital flow of digital currency exchanges is huge, with the average daily trading volume of the top five exchanges exceeding US$3 billion.

There are hundreds of digital currency exchanges around the world, some operating globally for the mainstream market, while some focus on niche markets.

For example, AAX is committed to providing services to digital currency traders and institutional investors, integrating the digital currency world with the global economy, and providing unparalleled first-class technical capabilities using a matching engine powered by LSEG Technology .

Many alternative coins have successfully occupied a certain market share shortly after their launch. What digital currency exchanges have in common is that they jointly provide the development ground for these alternative coins.

Digital currencies are no longer limited to Bitcoin. Other digital currency assets such as ETH, XRP, BCH, USDT, LTC, EOS, XTZ, etc., find a place in the portfolios and diversification strategies of many digital currency traders.

Currently, digital currency trading has many similarities with Forex trading, as the basic principles, tools, indicators, and strategies used in Forex also apply to digital currency trading. AAX Academy’s Digital Currency Trading section discusses these topics in depth and breadth.

Blockchain Protocol

Blockchain is the underlying technology that makes digital currency possible. There are many different blockchain protocols, each with slightly different technical features, pros and cons.

For example, the Bitcoin blockchain relies on mining and POW (Proof of Work) mechanisms to process transactions, while another blockchain may require no mining and use a DPOS (Delegated Proof of Stake) mechanism. In addition to the Bitcoin blockchain, other notable protocols are ETH, Hyperledger, EOS, XLM, IOST, KIN, TRX, and STEEM. Among these blockchain protocols, ETH (Ethereum) deserves credit for driving rapid innovation across the entire digital currency ecosystem.

The Ethereum platform was created by Vitalik Buterin, marking that developers can better utilize the resources of the platform by using its own programming language Solidity. Ethereum made blockchain technology popular, creating a new world of innovative decentralized applications based on smart contracts and custom tokens. Most altcoins currently are based on Ethereum’s ERC20 standard.

The decentralized finance movement, or DeFi for short, is also basically built on the Ethereum blockchain protocol.

Financial Services

For every service that exists in traditional finance, Ethereum-based DeFi applications have corresponding alternative versions for allpeople visit. DeFi applications allow users to create stablecoins, lend funds and earn interest, send and receive payments, obtain loans, conduct transactions, take positions on prediction markets, enter the real estate sector and much more. Smart contracts are the key to making decentralized services possible. Smart contracts automatically perform pre-agreed activities once certain conditions are met.

At the same time, traditional finance has also begun to turn to providing new customized services for the digital currency field. Currently, some fund managers offer investors the option of adding digital currencies to their portfolios, custodians provide security services to investors who have invested large amounts of money in digital currencies, and many analysts in mainstream media (such as Bloomberg) are also concerned about There is a lot of interest in digital currencies.

Cryptocurrency Hardware

For those who prefer to build their own security measures, there is a huge market for cryptocurrency hardware that caters to professional traders and long-term holders (HODLers). Tool of. Trezor and Ledger are the most reputable hardware wallets, and both essentially offer the same value to digital currency traders, namely a more secure way to store digital currency.

Of course, digital currencies stored in hardware wallets cannot be traded on the market. Therefore, digital currency traders often allocate funds between hardware wallets and exchanges at a certain ratio based on their trading style preferences.

Data Aggregators and Blockchain Analytics

There is so much activity across blockchains that a huge amount of data is being generated and has given rise to sub-industries namely Data Aggregators and Blockchain The emergence of the blockchain analytics industry. Companies like CoinMarketCap are the go-to source for quickly checking digital currency and exchange data. They collect trading volume, liquidity, market capitalization, price trends, circulation volume, and industry-wide statistics, such as total currency count, market volume, industry market capitalization, and BTC market capitalization share.

Those who are more interested in blockchain analysis can find the data they need on websites like Blocktivity. Here, you can view relevant data for each individual blockchain protocol, including the number of operations in the last 24 hours, the average number of operations in the last 7 days, market capitalization, and the CUI index, which is what remains after the actual usage of the current blockchain protocol Available capacity. Taken together, these websites can provide valuable insights specific to the blockchain industry.

For example, Ethereum has averaged 667,000 operations over the past 7 days, with a CUI slightly above 50%, while EOS has averaged 63 million operations over the same time frame, with a slightly lower CUI. at 50%. Technically speaking, the EOS protocol is more powerful than Ethereum. However, this cannot prevent Ethereum from occupying 70% of the total market capitalization of the most mainstream currencies.

Digital Currency Media and Conference

In today’s world, almost everyone is a publisher of content. Without the self-media industry, such a large-scale industry would cease to exist. Digital currency has given rise to a wide range ofThe media landscape covers news media, KOLs and related conferences targeting currencies, public chains and codes.

The leading digital currency media include Coindesk, Cointelegraph, Bitcoin Magazine, Decrypt, CCN, Bitcoinist, NewsBTC, etc. Some KOLs are also famous, and sometimes their audience even exceeds that of the news media.

YouTube celebrities such as DataDash, Dollar Vigilante, Altcoin Buzz, Ivan on Tech and Boxmining all have 200K to 300K subscribers. In the field of digital currency trading, CryptoTwitter’s top stars include VentureCoinist, CryptoCred and CryptoDonAlt, with 211K, 140K and 120K followers respectively.

If you want face-to-face communication with companies and people, the Digital Currency and Blockchain Conference is not to be missed. There are many conferences held every year around the world for investors, blockchain experts, startups, institutional finance, currency or protocol-related communities. In 2019 alone, we sponsored and attended Blockchain Live in London, The Capital Summit hosted by CoinMarketCap in Singapore, and Mobile World Congress in Shanghai. We had exciting meetings with other digital currency companies and major financial institutions, and established relationships with regulators from various jurisdictions.

Digital Currency Regulation

As the market and audience for the digital currency industry continue to grow, in most cases financial regulators are still developing relevant regulations to protect investors and consumers. frame. Regulators can take very different approaches, which is certainly a challenge for companies operating across multiple jurisdictions.

During the ICO boom of 2017 and 2018, many projects were launched before the regulatory framework was established, while some did not comply with the jurisdiction’s guidelines and were halted during the fundraising process. It all stems from how digital assets are classified, and the understanding of classification is constantly changing. Currently, we distinguish digital assets into security tokens and utility tokens.

In the past year, with the introduction of Libra, the regulatory push has also increased. The central bank is also actively exploring the significance of blockchain technology to its policies and economic activities, and continues to publish reports.

The digital currency ecosystem is developing rapidly

These components that make up the digital currency ecosystem are growing and developing in an orderly manner, contributing to an increasingly sound industry. From niche interest in 2009 to an active digital asset economy, digital currencies have come a long way.

However, in order to realize the industry’sTo develop and engage broadly, a strong ecosystem is not enough. We need to create better connections between digital currencies and global finance. The better the integration of digital currency and traditional finance, the easier it will be for newcomers to understand the digital currency ecosystem.

For everyone new, as exchanges, financial services, media and regulators adapt to mainstream consumer expectations, the digital currency industry will further develop, potentially improving investment outcomes.

❻ Ethereum does not need miners after its transformation

img src=' https://p26 . toutiaoimg.com/large/tos-cn-I-qvj 2 LQ 49k 0/cc 3c Fe 23 f 56 f 4395 abed 6162 CB 724352 '/

After the merger, energy consumption will be reduced by 99.95%

According to OKLink data, the world’s most active high-liquid blockchain network Ethereum The block height of 15537393 triggered the merge mechanism, resulting in the first PoS block (height 15537394). Since then, the Ethereum consensus has officially changed from PoW to PoS mechanism, completing this "merger" upgrade. This will bring significant changes to the Ethereum network, including a 99.95% reduction in energy consumption and a 90% reduction in ETH circulation. CoinMarketCap data shows that the real-time price of Ethereum is about $1,590, and the price fell by about 1.11% in 24 hours. Since then, it has regained the US$1,600 mark, with a market value of more than US$190 billion.

The new merger mechanism bids farewell to the "mining" era of large mining machines.

Ethereum is a public blockchain platform and its cryptocurrency is Ethereum ETH. Under the traditional "proof of work" mechanism, in the past few years, a large number of "mining owners" have purchased high-performance graphics cards to mine ETH. For miners, if mining is performed on Ethereum's main network, after the merger, each network will operate entirely based on the PoS proof-of-stake mechanism. By then, traditional proof-of-work (PoW) mining will no longer be possible on Ethereum. Ethermine, the world's largest mining pool for Ethereum, announced the termination of Proof of Work (PoW) related services and will no longer follow up on Proof of Work (PoW) forks in the future.

Ethereum initially adopted the PoW (proof-of-work) workload proof mechanism. The "miners" of the nodes competed for packaging rights based on their own computing power and received packaging rewards. Nowadays, Ethereum relies on the PoS (proof-of-stage) equity proof mechanism and bids farewell to the era of large-scale mining machines. Holders can "mine" by staking Ethereum tokens (ETH), and the pledge threshold is 32 ETH.

Will the merger of Ethereum put a large number of traditional blockchain miners out of work?

Will the merger of Ethereum put a large number of traditional blockchain miners out of work? According to Messari's estimate, the merger would force a $19 billionYuan's prisoner-of-war miners looked for another way out. Although miners can contribute some GPU computing power to some Web3 protocols, it is difficult for these protocols to bear all the computing power. Looking at the data, the total market value of GPU mineable tokens other than ETH is only $4.1 billion, accounting for approximately 2% of the market value of ETH. ETH mining income accounts for 97% of the daily income of GPU miners, which means that most existing Ethereum miners cannot find POW mining coins with the same economic benefits on the market.

According to the analysis of Sun Yulin, a senior researcher at Ouke Cloud Chain Research Institute, the graphics card market may be affected to a certain extent. Some miners have expressed their intention to switch to Ethereum Classic (ETC) (Note: Some proof-of-work miners have expressed their intention to resist the merger and have begun to jump back to the older Ethereum blockchain version, now called Ethereum Classic) continue mining. In addition, the merger of Ethereum has also given market opportunities to the Enclosure market, and some Ethereum mining pools have therefore launched transformation plans related to Enclosure.

What impact will the Ethereum merger have on the mining machine industry chain?

What impact will the epic "merger" of Ethereum have on China's related industrial chains? In 2017, with the rise of blockchain in the world, the trend of “mining” services began to emerge. Huaqiangbei computer dealer, which has a large number of high-computing game graphics cards, uses its own resources to transform into "mining." The “mining boom” has brought huge profits to Huaqiangbei computer and graphics card dealers. However, after the "tide" receded, graphics card prices plummeted. Coupled with policy crackdowns, "miners" turned to secret operations in remote areas.

It’s not just miners who are affected, life for miner manufacturers is no longer easy either. On August 26 this year, according to the second quarter financial report released by NVIDIA, revenue from CMP-related businesses such as foundry mining chips fell by 66% year-on-year.

Related Q&A: What is virtual currency mining?

Mining of virtual currency is a process that uses computer hardware to perform mathematical calculations for the virtual currency network to confirm transactions and improve security. As a reward for their services, miners receive fees included in the transactions they confirm, as well as newly created virtual currency.

❼ Will Bitmain sink to the bottom when the blockchain no longer requires mining machines?

At the end of March this year, Bitmain launched an ASIC-based Antminer X3. Mainly targeting Monero (XMR) and cryptocurrencies that rely on the CryptoNight algorithm, Monero immediately issued a counter-statement that it would change the core algorithm to combat the intrusion of ASIC computing power.

What would be the result if this appeared in the world of digital cryptocurrency? That is, wrong calculation results may be carried to the entire network without anyone noticing.

And more importantly, if a "calculator manufacturer" monopolizes the calculator market, it can also deliberately produce such calculators with errors to change the rules of mathematics.

After all, "calculation" in the field of encrypted digital currency is not as simple as 1+2+3. You cannot use paper money to manually verify Bitcoin.

The practical significance of Bitmain’s computing power monopoly

We have learned about attacks based on 51% of the computing power in various articles.

But the reality is that although about 78% of the world’s computing power was previously in mainland China, fortunately they were scattered in different mining pools and controlled by different people.

Although all PoW-based encrypted digital currencies are at risk of being attacked by 51%, few people can actually launch an attack due to the dispersion of computing power.

But what if the miners themselves do not want to launch an attack, but the mining machine manufacturer launches an attack?

Still using the metaphor just now, although each miner subjectively wanted to independently check the questions, the calculators in their hands were remotely tampered with and gave consistent wrong answers. This may pose a great threat to digital cryptocurrencies.

However, Bitmain, the manufacturer that has the absolute say in mining machines, once had such a problem.

In April 2017, the Antbleed backdoor was discovered in Bitmain mining machines. Although this is described as a "bug" in Chinese circles, Antbleed is more like an implemented and designed feature.

Anonymous personnel discovered that after an Antminer machine produced by Bitmain was connected to the Internet, it would regularly communicate with a domain name held by Bitmain and send the miner’s serial number, MAC address and IP address. Sent back to Bitmain’s servers. And if Bitmain's server gives a negative signal, the mining machine will terminate its operation.

Although Bitmain responded that they cannot shut down any mining machines that do not belong to them. However, the Bitcoin Core team proved in experiments that this function does not have any verification, and anyone can shut down the mining machine by forging DNS - but this also means that Bitmain has the ability to shut down any sold mining machine.

Afterwards, Bitmain fixed this "loophole", but it triggered heated discussions in the community. This also sets the tone that almost all PoW blockchain communities are biased against Bitmain.

A few months later, under the leadership of Bitmain, ViaBTC dug out the first block and conducted a hard fork of the Bitcoin blockchain. From then on, there was Bitcoin Cash (BitcoinCash) in the world. ).

Will the monopoly of mining machines destroy the distributed system?

Faced with this question, we should now have a clear answer. That is, the monopoly of mining machines will definitely affect the safe operation of PoW digital cryptocurrency.

This issue does not lie in whether Bitmain and its founder Wu Jihan are trustworthy, but in that one of the values ​​of any blockchain system should be to exclude any risk to any single company or individual. Operate safely with trust.

Even if the ASIC mining machine is not monopolized by Bitmain, the ASIC mining machine itself will increase the concentration of computing power.

ASIC pairing for miningThere are great requirements for wind, electricity and space, and it has no use except for mining. At the same time, due to the powerful computing power, it increases the computing difficulty of the entire network.

This makes it difficult for external players to download software on their computers and start mining like they did 5 years ago. The recent frequent hacking incidents of centralized exchanges also prove that concentration in this unregulated market will definitely lead to insecurity.

Assuming that the Bitcoin network is running on 1 million miners, no one can shut it down. And if the Bitcoin network is running on 20 large mining farms, it will be much easier to shut it down.

As of the end of 2017, 78% of the computing power was concentrated in mainland China, which led to the possibility that Chinese regulatory authorities would actually launch a fatal attack on Bitcoin.

Moreover, most of the usage scenarios of digital cryptocurrency are related to "decentralization". Once centralized, it will mean that these usage scenarios will no longer exist. As a result, a potentially valuable project turns into an air coin that is a pure waste of computing power.

So, what measures should we take to face this situation?

First of all, as a project party, it may be time to abandon the pure PoW mechanism. In fact, in many projects that issue encrypted digital currencies, especially in asset securitization projects. PoS, which is similar to the stock concept in the real world, is inherently more reasonable than PoW.

We often hear the saying "Bitcoin wastes a lot of computing power and is worthless" in the media who don't understand the blockchain. This makes sense to a certain extent. It is difficult for blockchains based on PoW to bind the value of the project itself to the digital cryptocurrency issued - because the real value behind the price of the currency does not come from the project, but from the cost of maintaining computing power.

The hybrid model of PoW+PoS is more like the future. In the hybrid model, both currency holders and miners can participate in major decisions of this community. And if a decision is widely recognized, the blockchain will be soft-forked to the latest state without excessive intervention by developers, and there will be almost no private resistance from miners or mining machines.

Secondly, as a retail miner, if you are still mining a pure PoW mechanism currency, then you should unconditionally support the fork activities initiated by the community to resist ASIC mining machines, even if this will Cause your mining machine to fail.

This may sound contradictory, but from a long-term perspective, it is better to promote the reform of the community and gain more benefits than to fish in a currency controlled by a computing power monopoly. Because, in many conflicts between computing power and the community in the past, the final result was that the computing power master would forcefully retain the old algorithm and perform a hard fork of the blockchain.

Just like ETH and ETC, the classic Ethereum (ETC), which is dominated by computing power, has lost the support of developers and has become an air currency without vitality and impossible to develop applications.

As a retail investor, you should be cautious when tradingNon-mainstream digital currencies (except Bitcoin) supported by Yibitmain mining machines avoid falling into a blockchain where the computing power is completely controlled by Bitmain.

Finally, if you were Bitmain, what should you do?

Bitmain’s goal is to become Intel, AMD and Nvidia, make greater contributions to the entire computer industry, and become a great company, rather than just focusing on the immediate benefits of mining.

Wall Street financiers have long seen through the violence caused by Nvidia graphics card mining. The company’s stock price has risen and fallen in line with the price of Bitcoin, and is even said to be affected by the digital currency market. Impact. Citron, a well-known short-selling agency, has recently been short on Nvidia, believing that the company focuses too much on providing services for digital currency miners instead of focusing on serious businesses such as artificial intelligence, games and driverless driving.

The mission of chip manufacturers is to provide more powerful chips to drive more intelligent services, and finally contribute to the real world, rather than becoming a monopoly tycoon in the virtual world. When everyone no longer enters the door of the virtual world, what is left is just a deserted wasteland.

In an interview with US media last year, Wu Jihan revealed that he would conduct an IPO with a market value of billions of dollars. As a company that is about to go public, Bitmain must not only be responsible to investors, but also accept questions from investors about the sustainability of the business, "What should you do if your mining machine encounters a fork when it goes public?"

This question, which needs to be asked after it is listed, has already appeared: the current price of XMO, the forked currency after the Monero team forked, is 7.5 US dollars, while the current price of the real Monero XMR is At $194, the forked currency was completely abandoned by the Monero community.

Before Bitmain becomes a name spurned by all blockchain communities, it can completely rely on the huge capital accumulated in the past few years to transform into an artificial intelligence chip company along the previous plan, instead of continuing to develop various Various digital currency mining machines come to extract the last drop of oil before ecological collapse.

❽ How to make money with blockchain and how to make money with blockchain

The development of blockchain technology has made it a Planting a new currency has also become a new way to make money. So, how to make money with blockchain and how to make money with blockchain?

itialg) project to obtain income, this is a new financing method in which investors can directly invest in ICO projects and obtain newly issued cryptocurrency.

Again, you can make money through trading. Cryptocurrency trading refers to the buying and selling of cryptocurrencies, that is, investors can earn profits by buying and selling cryptocurrencies. Investors can buy and sell cryptocurrencies on exchanges, as well as on other platforms. In the process of trading cryptocurrency, investors can make profits by buying at low prices and selling at high prices.

, you can also make money by developing applications. Investors can develop applications based on blockchain technology to gain income. Blockchain technology can be used to develop various applications, such as financial services, smart contracts, supply chain management, etc. Investors can develop applications based on blockchain technology to earn profits.

In short, there are many ways to make money using blockchain, including mining, investing, trading, and developing applications. Investors can choose the appropriate method to obtain returns based on their own circumstances. However, before investors use blockchain to make money, they also need to understand market dynamics and control risks.

❾ How to identify the real blockchain digital currency

Whether a certain digital currency is a valuable currency is basically in the "angel round" stage at present. There are three judgment criteria, one is the team, the other is the economic model, and the third is industry demand.

The randomness of the team is too great and will not be discussed here. This article first conducts a detailed analysis of the economic model of digital currency. In subsequent articles, the author will analyze some digital currencies according to different industries.

Strictly speaking, the economic model involved in this article is not completely equivalent to the concepts described in economics. Specifically refers to the consensus mechanism and incentive mechanism of currency in digital currency.

1. Consensus Mechanism

The consensus mechanism is the strategy and method for each node in the blockchain system to reach agreement, and should be flexibly selected according to the system type and application scenarios.

Commonly used consensus mechanisms mainly include PoW, PoS, DPoS, PBFT (and their variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this article evaluates the technical level of various consensus mechanisms according to the following dimensions:

a) Compliance supervision: whether it supports Super The authority node supervises the nodes and data of the entire network;

b) Performance efficiency: the efficiency of the transaction reaching consensus and being confirmed;

c) Resource consumption: the CPU, Network input, output, storage and other computer resources;

d) Fault tolerance: the ability to prevent attacks and fraud.

1 Industry background

Find industry pain points: Asset management requires a professional team and knowledge, but most digital currency investors now do not have it; digital The currency market fluctuates greatly, and investors are unable to preserve the value of their assets when the market falls.

2 Own advantages

Having been deeply involved in the stock and futures markets for many years, it has a mature and high-quality asset management team; the AI ​​big data team has strong technical strength.

3 Market Research

After conducting market research, it is estimated that the market value of asset management will be approximately US$1 billion in the next five years.

4 Total amount of digital currency
