2. Four major highlights in the blockchain field in 2022 | Interface Prophet⑯

There is a core proposition about the "Impossible Triangle" in the blockchain field, which are Security, performance and decentralization. This proposition is the foundation of the evolution of blockchain technology. Whether it is Bitcoin, Ethereum, or the vigorously developed alliance chain, it is essentially a trade-off between the above three elements.

As Ethereum’s core position among blockchain developers is determined, performance has gradually become a bottleneck for its development, so in the foreseeable 2022, improving performance and efficiency will be a long-term and critical issue.

Based on the Ethereum ecosystem, to improve performance within the limits of the "Impossible Triangle", the current path has been clear. The first one is the Layer 1 level, that is, other public chains share the burden of Ethereum. Data pressure.

One of the major trends in 2021 is the increased use of Layer 1. The space is currently dominated by Solana, Avalanche, Terra and Binance Smart Chain, each with a growing ecosystem. The value has exceeded 10 billion US dollars.

The second type is Layer 2, which is based on the Ethereum main network, but transfers settlement to the second layer network to improve efficiency. This is what Ethereum is working on, Layer 2 is often called rollups because they "aggregate" or bundle transactions together and execute them in a new environment before sending updated transaction data back to Ethereum.

As for the most critical data verification link of the blockchain, Layer2 currently has two technical solutions, one is called "Optimistic rollups" and the other is called "ZK Rollups". Both technical routes have teams developing corresponding networks and have ecological support, such as Arbitrum, which chooses "Optimistic rollups", and dYdX, which chooses "ZK Rollups".

Between Layer1 and Layer2, there is another solution called "side chain", which is partially compatible with the Ethereum main network, but does not belong to Layer2. They are specially used to deal with the excess of Ethereum. capacity, rather than competing with Ethereum as a whole, and hosting Ethereum applications in a complementary manner.

Starting with DeFi, which currently has the most active users, according to statistics from DeFi Lama, the amount of DeFi locked on Ethereum has exceeded 100 billion US dollars, and other public chains such as BSC, Solana, and Avalanche have also Attracting nearly US$49 billion in funds, it has become a very active financial scene.

Although the data of many public chains is quite large, different chains are like data islands, and assets on different chains cannot be freely exchanged. In addition, many emerging public chains are not as developed as Ethereum and lack many foundations. Facilities such as stablecoins, NFT games, and more.

Therefore, assets on other chains need to be introduced into one's own public chain through cross-chain. Among the currently commonly used cross-chain methods, in addition to cross-chain currency withdrawals in centralized institutions such as exchange wallets , the most common ones are various decentralized cross-chain asset bridges.

For cross-chain bridges, the most important question is howHow to reach a consensus is to a large extent related to the security of investors’ assets under custody. For now, the cross-chain bridge of a centralized exchange is the most convenient cross-chain bridge for users, but the central There is a single point of failure problem in the cross-chain bridge of exchanges. In addition, the current cross-chain bridge is gradually developing in the direction of non-custodialization in order to further protect the security of users' assets.

The full name of DAO is "Decentralized Autonomous Organization", which is a management model that attempts to get rid of the traditional bureaucracy and uses blockchain technology to complete autonomous operations. organizational form.

Decentralized Autonomous Organizations (DAOs) enable global coordination of individuals using blockchain-based governance. DAOs can be used for many purposes, including managing the operations and capital of a blockchain project (MakerDAO), managing investment capital (The LAO), managing the use of game assets (YGG DAO), coordinating cultural groups (Friends With Benefits), or coordinating purchases Asset (Constitution DAO).

The number of DAOs included in the deep website has reached 187, with total assets under management exceeding US$12 billion and covering more than 1.6 million members. Although in the blockchain field, this is not a huge amount of data. But institutions including Sequoia Capital are beginning to take notice of this new term.

The market value of cryptocurrencies officially exceeded US$2 trillion in 2021 and is now at US$2.5 trillion, an increase of 175% from the beginning of the year. Along with the explosive growth of market value, financing in the encryption field has also increased rapidly. According to statistics, there were 1,529 publicly disclosed primary market financings in the encryption industry in 2021, totaling approximately US$32.6 billion, with a year-on-year growth of an exaggerated 814.2%.

However, equity financing in the crypto field is different from other fields. Under the "VIE" structure, the main exit channel for traditional VC funds is for companies to land on the secondary market for IPO. However, the blockchain field has its own new financing method ICO (banned in China). The key difference of this decentralized financing method is that users can participate in the growth of the community at an earlier stage, while under the traditional venture capital model, only logging in After the secondary market, ordinary investors have the opportunity to share the dividends of corporate growth.

In the field of encryption, first of all, the concept of "company" has been weakened. Due to the existence of "Web3" and "DAO", communities and organizations are more mentioned. Users are naturally interested in There is a sense of distrust in centralized platforms.

The hottest project in the crypto community in the past two weeks is called "OpenDao", which is an imitation of the leading NFT trading platform "OpenSea".project, and the reason why this project is so popular comes from the dissatisfaction of crypto players with "OpenSea". It has recently been reported that "OpenSea" is undergoing a new round of financing and is preparing for an IPO. However, NFT enthusiasts do not want “OpenSea” to become a monopoly platform like the current Internet giants, so “OpenDao” adopts the concept of decentralization and issues airdrops to all “OpenSea” users.

And at the end of 2021, there was a debate in the encryption community about "Web3", including Tesla Chairman Elon Musk and former Twitter executive Jack Dorsey pointing to contradictions during the debate I have learned about venture capital institutions in crypto finance and believe that VCs have gained too much profit.

In 2021, an investment institution in the form of "DAO" also emerged. This kind of organization includes investors who are very influential in the community and are deeply involved in the technology field. They incubate The project performance even exceeds the results of some traditional VCs.

3. What are the good blockchain projects in 2020?

The history of digital currency has developed for more than ten years since the birth of Bitcoin in 2009, with a total of Tens of thousands of blockchain projects have experienced the blockchain 1.0 and 2.0 eras. Blockchain is about to enter the 3.0 era, that is, the era of token economy. The emergence of commercial platforms has made the 'token economy' possible and brought It has promoted the development of productivity and the transformation of production relations.

Based on this background, NGK Token came into being. The platform has many technologically leading R&D elites and strong support from many powerful investment companies. It is regulated by SEC in the United States. Supervised by the Securities and Exchange Commission.

Since 2018, the NGK.I0 team has been concentrating on researching and launching a profit method that combines the NGK blockchain digital currency fund and industrial ecology to comprehensively create a more complete business ecosystem. Will once again lead the blockchain market

As a barrier-free pass on the NGK.IO platform, the NGK pass can connect online and offline merchants from all walks of life and realize commercial applications. It not only helps traditional Industrial transformation and upgrading have also leveraged the Internet economy and promoted the development of the real economy

NGK.IO has a built-in Turing-complete programming language that users can use to construct and define their own With this feature, you can develop your own applications and blockchain systems, and issue your own currency.

NGK.IO also has side chains that can be customized with one click. NGK.IO provides proprietary cross-chain and cross-contract technology, linking the main chain and side chains together. Whether it is contract assets on NGK.IO or assets not on NGK.IO, they can be used through the cross-chain and cross-smart contract technology of NGK.IO Complete value transfer and exchange freely.

Moreover, NGK.IO does not need to consume GAS at every step like Ethereum when running smart contracts. This makes it possible for users to use Dapps for free, which is more in line with the concept of using Internet products for free and relying on value-added services and advertising to make profits. Business Model

So we can think that Dapps developed based on NGK.IO are real Dapps.

The design goal of NGK.I0 is to exceed 1 million TPS, and it is proposed that the block confirmation time of NGK.IO will reach 3 seconds. Therefore, NGK.IO will have very excellent performance and is expected to change The current situation of blockchain technology being unable to be implemented

From this, we can foresee that in the future, many blockchain entrepreneurial projects will choose to issue tokens based on NGK.IO, develop a large number of Dapps that can be implemented, and attract a large number of Billions of users are using it

NGK.IO is expected to form a rich and complete business ecosystem, and at the same time generate a large demand for transaction tokens.

NGK.IO makes full use of the blockchain and the NGK.IO ecosystem to establish a secure, verifiable, fair, decentralized, trustless, and borderless business and financial area. The blockchain system provides innovative enterprise teams with financial services and industry incubation services such as industrial funds, Internet funds, blockchain funds, Internet of Things and artificial intelligence, and creates a world-class ecological business closed loop.

And through cross-chain, value exchange can be formed for different consumption scenarios, providing certain technical strength for the commercialization process of the global "token economy"!

I believe that in the future NGK.IO will definitely improve the speed of value exchange by leaps and bounds, thereby realizing a truly united and interoperable value network! #digital currency # #blockchaininformation # #currency circle news # #Mining gold rush # #currency circle news #

4. What is the recent development of the blockchain? Are there any formal projects to introduce?

China’s blockchain industry expenditure scale in 2018 And application prospect analysis will be close to 300 million US dollars in 2019, solving shortcomings and promoting economic development

Blockchain technology is expected to be widely used in the economic field

Blockchain technology is important for cultivating new drivers of economic growth, Building an honest society, improving the level of management technology, and alleviating the financing difficulties of small and medium-sized enterprises have strong practical significance and are expected to be widely used in the economic field. At present, the application of blockchain technology is still in the early stage of development and faces many challenges. We must actively promote the application of blockchain in multiple fields, scenarios and environments of the economy and society, create a good industrial development environment, improve the quality of development, and strengthen Blockchain core technology research and development, professional application demonstration, strengthening standard manufacturing, talent training and the construction of public service platforms.

China Blockchain in 2019The scale of market expenditure will be close to US$300 million

According to statistics from the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in China's Blockchain Industry" released by the Qianzhan Industry Research Institute, as of 2017, China's blockchain The scale of market expenditure is only US$83 million. In 2018, China’s blockchain market expenditure will reach US$160 million. It is also predicted that China’s blockchain market spending will be close to US$300 million in 2019. At this stage, the overall market size of blockchain is small. This is because most of the blockchain projects on the market are in the experimental stage and the investment is not large. On the other hand, many companies have realized the potential of blockchain and plan to increase their budgets in the future. Affected by this, China's blockchain market will usher in rapid growth, with market expenditures expected to reach US$1.95 billion in 2023. The average annual compound growth rate from 2019 to 2023 is 60.51%.

Statistics and forecasts of China’s blockchain market expenditure from 2017 to 2023

Analysis of unfavorable factors for the development of China’s blockchain

1. The technology is not mature enough. At present, blockchain technology is not yet mature in terms of system stability, application security, and business models, and cannot meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance issues. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion and high-frequency business needs are difficult to meet. Many projects are also working on optimization, but they are far from real scenarios such as banks. There is still a certain distance between the transaction throughput of , stock exchanges, etc. Second, there is the issue of consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, causing the blockchain to waste a lot of computing power and matching power across the entire network. In terms of types, the current blockchain consensus mechanisms are too few in type and will be diversified in the future. In business scenarios, a richer consensus mechanism is inevitably needed to adapt. Third, security issues. Issues such as privacy protection, harmful information on-chain, smart contract vulnerabilities, consensus mechanism and private key protection, computing power attacks, cryptographic algorithm security, etc. all make the blockchain face a severe situation of platform security and application security. Fourth, database issues. Unlike traditional databases, blockchain applications require a large number of write operations, HASH calculations, and verification operations. Database systems specifically for blockchain are still difficult to overcome.

2. The application scenario is unclear

Currently, the blockchain project is still in the exploratory stage, and no specific implementation scenario can be found. At present, promising areas include finance, sharing economy, Internet of Things, public services, etc. However, judging from the maturity of existing blockchain technology, there are still many problems in blockchain applications, and there is still a gap between actual use. First, the immaturity of blockchain technology has restricted commercial applications. Although there are currently many types of core blockchain technologies such as privacy protection algorithms and consensus mechanisms, they are generally not commercially available. Second, the application model of blockchain is stillDuring the exploration, the “irreplaceable” advantages of blockchain have not yet been realized. The blockchain itself represents a consensus system, and a consensus system that conforms to the corresponding business scenario should be built from a higher level, not just "business + blockchain". China has a large number of users, complex business scenarios, and any commercial product will involve a very large traffic and population, and the current blockchain technology cannot satisfy it.

3. Scarcity of professional talents

Blockchain technology is a multi-disciplinary and cross-field technology, which mainly involves operating systems, network communications, cryptography, mathematics, and finance. , production, etc., but currently our country still has shortcomings in interdisciplinary fields and fields, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a huge gap in R&D technical talents. Blockchain technology research and development mainly focuses on programming languages ​​​​such as Go, Javascript, C and C+, and new smart contracts use new functional programming languages ​​​​such as Haskell, Ocaml, and Rholang. There is a huge gap in China's talent market for technical talents with senior R&D experience in relevant languages. On the other hand, there is a lack of design talent at the bottom level. Different from R&D technical talents, blockchain underlying system architecture design talents must master multiple cross-disciplinary professional skills. They must not only have an in-depth understanding of the underlying design principles of blockchain and have experience in the design of various system architectures, but also master the business logic of specific application scenarios. . Although some colleges and universities have launched cross-disciplinary education and blockchain-specific technical disciplines, professional talents are still very scarce.

Analysis of favorable factors for the development of China’s blockchain

1. Favorable policies promote development. In January 2017, the Ministry of Industry and Information Technology released the "Software and Information Technology Service Industry Development Plan (2016-2020)", which proposed requirements for innovation in blockchain and other fields to reach international advanced levels. In August 2017, the State Council issued the "Guiding Opinions on Further Expanding and Upgrading Information Consumption to Continuously Release the Potential of Domestic Demand" and proposed to carry out pilot applications based on new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" proposing to study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on the supply chain.

In March 2018, the Ministry of Industry and Information Technology released the "Key Points of the Standardization Work of the Informatization and Software Service Industry in 2018", proposing to promote the establishment of the National Informatization and Industrialization Integrated Management Standardization Technical Committee, the National Blockchain and Distributed Records Accounting Technology Standardization Committee. In June 2018, the Ministry of Industry and Information Technology issued the "Industrial Internet Development Action Plan (2018-2020)" to encourage and promote the application research of emerging cutting-edge technologies such as edge computing, deep learning, and blockchain in the Industrial Internet.

Since blockchain was first included in the "13th Five-Year Plan" National Informatization Plan in 2016, blockchain has increasingly received attention and attention from the national government. Beijing, Shanghai, Guangdong, Hebei, Jiangsu, Shandong, Guizhou, Gansu, Hainan and other 24Provinces, cities or regions have launched dividend policies, carried out the layout of the blockchain industry chain, and actively explored industry applications based on blockchain.

2. The blockchain industry is gradually taking shape

At present, my country’s blockchain technology continues to innovate, and the blockchain industry is gradually taking shape, starting in supply chain finance, credit reporting, and product traceability. , copyright transactions, digital identity, electronic evidence and other fields are expected to promote technological changes, organizational changes and efficiency changes in our country's economic system, making important contributions to building a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises has increased rapidly. Blockchain applications will be implemented faster, boosting the high-quality development of traditional industries, accelerating industrial transformation and upgrading, using blockchain technology to "reduce costs" and "increase efficiency" for the real economy, and promote the standardized development of traditional industries. In addition, blockchain technology is deriving into new business formats and becoming a new driving force for economic development. Blockchain technology is promoting a new round of business model changes and becoming an important support for building an honest social system.

3. Broad application prospects in the future

In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, the flow of all digital assets can be traced There will be "chains" to check. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, reduce the complexity of transactions, increase the end-to-end speed of transactions, reduce communication costs in the transaction process, and improve the transparency and non-tamperability of transaction records. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, has always been high, and there are complex manual processes. Blockchain technology has data that cannot be tampered with and is traceable, and its application can help reduce financial costs. The cost of reconciliation and dispute resolution between institutions can significantly improve the processing speed and efficiency of payment business, and also make small-amount cross-border payments possible. In addition, the application of blockchain will also extend to many fields such as medical health, education, charity, social management, etc. The market prospects are very broad.

5. Energy Blockchain Research丨Four major blockchain development trends that are expected to become “evergreen trees”

Blockchain technology continues to develop and expand to adapt to the financial market and Internet market needs and continue to provide digital solutions. By integrating blockchain technology in Web3 technology, we are developing decentralized finance (DeFi) services and decentralized applications (DApps) to enhance the digital ecosystem.

Experts estimate that by integrating blockchain technology and solutions, banks can save $12 billion or more annually. The United Nations also uses blockchain technology to address issues related to human rights violations, fund international humanitarian development, and promote environmentally friendly blockchain ecosystem innovation.

One of the challenges with blockchain trends is that they are fleeting because the industry is constantly evolving. Therefore, some companies and developers often have questions about the development of a certain blockchain project. However, after diligent research and analysis, we have discovered the following four itemsThe project has the potential to become an “evergreen” blockchain development trend. What’s more, these four projects are actively providing blockchain solutions to developers in the decentralized finance and decentralized application industries.

1

Blockchain Applications in Enterprises

Developers who want to create high-quality decentralized applications can do so with Jelurida's flagship blockchain Solutions "NXT and Ardor" to build scalable applications that meet market needs. To put it simply, Jelurida is working hard to seamlessly connect physical companies and enterprises with the blockchain industry. Imagine, is a blockchain without practical application still a blockchain?

Futurecoin is the world's first open source blockchain platform that relies entirely on Proof of Stake (PoS) consensus. Proof of Stake is an algorithm based on Byzantine fault tolerance that eliminates computational loss in the Proof of Work (PoW) model and improves transaction security.

Developers can leverage the Futurecoin framework to build and save custom blockchain solutions and create reliable exchanges for tokens. On the other hand, AdoCoin’s sub-chain functionality allows organizations to build permissionless blockchain digital solutions and run smart contracts.

By using these solutions and Ignis, Jelurida has achieved some success. Unlike some blockchain companies, Jelurida has achieved all milestones in its development path and currently operates in several countries on three continents.

Currently, Jelurida has many real-life projects running on its platform, one of which is Cycle4Value, an environmentally friendly gamification system that can control traffic conditions and improve public health.

Speed ​​and data security

When a developer wants to create a decentralized blockchain service with scalability and reliability, Speed ​​and safety are the basic factors he needs to consider. Elrond has done just that, processing more than 10,000 transactions in one second, which is 100 times faster than Bitcoin and Ethereum combined.

Here are some of the “evergreen” trends we need in the coming years.

Elrond uses an adaptive state sharding mechanism to support fast verification and transaction processing. Like Jelurida, Elrond uses proof of stake to save resources and improve transaction security.

With over 90,000 active accounts and a large number of development projects, it’s no surprise that Elrond’s ecosystem valuation has jumped from $10 million to $500 million. Elrond operates in approximately 30 countries and counts more than 115 companies and startups among its clients.

6. 108 knowledge points for getting started with blockchain

1. What is blockchain

< p> Pack the information of multiple transactions and the information indicating the block together. The verified package is the block.

Each block stores the hash value of the previous block, creating a relationship between blocks, that is to say, a chain. Together they are called blockchain.

2. What is Bitcoin

The concept of Bitcoin was proposed by Satoshi Nakamoto in 2009, with a total number of 21 million. The Bitcoin chain generates a block approximately every 10 minutes, and this block is mined by miners for 10 minutes. As a reward to miners, a certain number of Bitcoins will be issued to miners, but this certain number is halved every four years. Now it's 12.5. If this continues, all Bitcoins will be available in 2040.

3. What is Ethereum

The biggest difference between Ethereum and Bitcoin is the smart contract. This allows developers to develop and run various applications on it.

4. Distributed ledger

It is a database that is shared, replicated and synchronized among network members. To put it bluntly, all users on the blockchain have accounting functions and the content is consistent, which ensures that the data cannot be tampered with.

5. What is quasi-anonymity?

I believe everyone has a wallet, and the wallet address (a string of characters) used to send transactions is quasi-anonymity.

6. What is open transparency/traceability

The blockchain stores all data from history to the present, anyone can view it, and can also view any data in history.

7. What is tamper-proof

Historical data and current transaction data cannot be tampered with. The data is stored in the block on the chain and has a hash value. If the block information is modified, its hash value will also change, and the hash values ​​of all blocks following it must also be modified to form a new chain. At the same time, the main chain is still conducting transactions to generate blocks. The modified chain must always generate blocks synchronously with the main chain to ensure that the length of the chain is the same. The cost is too high, just to modify a piece of data.

8. What is anti-DDoS attack

DDoS: Hackers control many people’s computers or mobile phones and allow them to access a website at the same time. Since the bandwidth of the server is limited, a large amount of traffic The influx of data may cause the website to fail to function properly, resulting in losses. But the blockchain is distributed. There is no central server. If one node fails, the other nodes will be affected.Nodes are not affected. Theoretically, if more than 51% of the nodes are attacked, problems will occur.

9. Definition of main chain

Taking Bitcoin as an example, at a certain point in time, a block is mined by two miners at the same time, and then 6 blocks are generated first. The chain of blocks is the main chain

10. Single chain/multi-chain

Single chain refers to the data structure that handles everything on one chain. The core essence of the multi-chain structure is composed of public chain + N sub-chains. There is only one, but in theory there can be countless sub-chains, and each sub-chain can run one or more DAPP systems

11. Public chain/alliance chain/private chain

Public Chain: Everyone can participate in the blockchain

Alliance chain: Only alliance members are allowed to participate in accounting and query

Private chain: Writing and viewing permissions are only controlled by one person In the hands of the organization.

12. Consensus layer, data layer, etc.

There are six overall structures of the blockchain: data layer, network layer, consensus layer, incentive layer, contract layer, and application layer. Data layer: a layer that records data, belonging to the underlying technology; network layer: a structure for building a blockchain network, which determines how users are organized. Consensus layer: Provides a set of rules to allow everyone to reach agreement on the information received and stored. Incentive layer: Design incentive policies to encourage users to participate in the blockchain ecosystem; Contract layer: Generally referred to as "smart contracts", it is a set of contract systems that can be automatically executed and written according to their own needs. Application layer: Applications on the blockchain, similar to mobile apps. Former Distributed Storage R&D Center

13. Timestamp

The timestamp refers to January 1, 1970 Day 0 hours 0 minutes 0 seconds 0... The total number of seconds from the current time to now, or the total number of nanoseconds and other very large numbers. Each block is generated with a timestamp indicating when the block was generated.

14. Block/block header/block body

Block is the basic unit of blockchain, and block header and block body are components of blockchain. The information contained in the block header includes the hash of the previous block, the hash of this block, timestamp, etc. The block body is the detailed data in the block.

15. Merkle tree

Merkle tree, also called binary tree, is a data structure for storing data. The bottom layer is the original data contained in all blocks, and the upper layer is each The hash value of a block, the hash of this layer is combined in pairs to generate a new hash value, forming a new layer, and then upwards layer by layer, until a hash value is generated. Such a structure can be used to quickly compare large amounts of data without downloading the entire dataYou can quickly find the lowest level historical data you want.

16. What is expansion?

The size of a Bitcoin block is about 1M and can save 4,000 transaction records. Expansion means making the block larger so that more data can be stored.

17. What is a chain?

Each block will save the hash of the previous block, creating a relationship between the blocks. This relationship is a chain. Data such as block transaction records and status changes are stored through this chain.

18. Block height

This is not the height mentioned in terms of distance. It refers to the total number of blocks between the block and the first block on the chain. This height indicates which block it is, and is just for identification purposes.

19. Fork

Two blocks were generated at the same time (the transaction information in the block is the same, but the hash value of the block is different), and then in Two chains are forked from these two blocks. Whoever generates 6 blocks from these two links first will be the main chain, and the other chain will be discarded.

20. Ghost Protocol

Mining pools with high computing power can easily generate blocks faster than mining machines with low computing power, resulting in most of the blocks on the blockchain being generated by these mining pools with high computing power. However, the blocks generated by mining machines with low computing power are not stored on the chain because they are slow, and these blocks will be invalid.

The ghost protocol allows blocks that should be invalidated to remain on the chain for a short time, and can also be used as part of the proof of work

. In this way, miners with small computing power will contribute more to the main chain, and large mining pools will not be able to monopolize the confirmation of new blocks.

21. Orphan block

As mentioned before, orphan blocks are blocks generated at the same time. One of them forms a chain, and the other does not form a chain. Then this block that does not form a chain is called an orphan block.

22. Uncle block

The orphan block mentioned above, through the ghost protocol, makes it part of the proof of work, then it will not be discarded and will be saved in the main chain superior. This block is the next

23 replay attack

The hacker resends the message that has been sent to the server. Sometimes this can deceive the server into responding multiple times.

24. Directed acyclic graph

Also called data set DAG (directed acyclic graph), DAG is an ideal multi-chain data structure. Most of the blockchains mentioned now are single chains, that is, oneBlocks are connected to one block, and DAG is connected to multiple blocks. The advantage is that several blocks can be generated at the same time, so the network can process a large number of transactions at the same time, and the throughput will definitely increase. However, there are many shortcomings and it is currently in the research stage.

25. What is mining

The mining process is to perform a series of conversions, connections and hash operations on the above six fields, and continue to try them one by one. The random number you are looking for, and finally successfully find a random number that meets the conditions: the value after hashing is smaller than the hash value of the preset difficulty value, then the mining is successful, and the node can broadcast the area to neighboring nodes. block, neighboring nodes receive the block and perform the same operation on the above six fields to verify compliance, and then forward it to other nodes. Other nodes also use the same algorithm to verify. If there are 51% of nodes in the entire network If all verifications are successful, even if this block is truly "mined" successfully, each node will add this block to the end of the previous block, delete the list in the block that is the same as its own record, and resurrect again. the above process. Another thing to mention is that regardless of whether the mining is successful or not, each node will pre-record the reward of 50 Bitcoins and the handling fees of all transactions (total input-total output) in the first item of the transaction list (this is " The most fundamental purpose of "mining" is also the fundamental reason to ensure the long-term stable operation of the blockchain), the output address is the address of this node, but if the mining is unsuccessful, the transaction will be invalidated without any reward. Moreover, this transaction called "production transaction" does not participate in the "mining" calculation.

26. Mining machines/mines

Mining machines are computers with various configurations, and computing power is the biggest difference between them. A place where mining machines are concentrated in one place is a mining farm

27. Mining pool

Miners unite to form a team, and the computer group under this team is a mining pool. Mining rewards are distributed based on your own computing power contribution.

28. Mining difficulty and computing power

Mining difficulty is to ensure that the interval between generating blocks is stable within a certain short time, such as Bitcoin is issued in 10 minutes

p>

Block 1. The computing power is the configuration of the mining machine.

29. Verification

When verification in the blockchain is a confirmation of the legality of the transaction, each node will verify the transaction once when the transaction message is propagated between nodes. Whether the transaction is legal. For example, verify whether the syntax of the transaction is correct, whether the transaction amount is greater than 0, whether the entered transaction amount is reasonable, etc. After passing the verification, it will be packaged and handed over to the miners for mining.

30. Transaction broadcast

The node sends information to other nodes through the network.

31. Mining fees

The blockchain must be likeIt works non-stop like a perpetual motion machine, requiring miners to maintain the system. Therefore, the miners must be given favorable fees to make it sustainable.

32. Transaction confirmation

When a transaction occurs, the block recording the transaction will be confirmed for the first time, and will be confirmed in every area on the chain after the block. Block is reconfirmed: When the number of confirmations reaches 6 or more, the transaction is generally considered safe and difficult to tamper with.

33. Double transaction

That is, I have 10 yuan, I use the 10 yuan to buy a pack of cigarettes, and then instantly use the 10 yuan that has not yet been paid. Bought another cup of coffee. So when verifying the transaction, you need to confirm whether the 10 yuan has been spent.

34. UTXO unspent transaction output

It is a data structure containing transaction data and execution code, which can be understood as digital currency that exists but has not yet been consumed.

35. Transactions per second TPS

That is throughput, tps refers to the number of transactions the system can process per second.

36. Wallet

Similar to Alipay, it is used to store digital currencies, and blockchain technology is more secure.

37. Cold wallet/hot wallet

A cold wallet is an offline wallet. The principle is to store it locally and use QR code communication to prevent the private key from touching the Internet. A hot wallet is an online wallet. The principle is to encrypt the private key and store it on the server. When it is needed, it is downloaded from the server and decrypted on the browser side.

38. Software Wallet/Hardware Wallet

A software wallet is a computer program. Generally speaking, a software wallet is a program that interacts with the blockchain and allows users to receive, store, and send digital currencies and can store multiple keys. Hardware wallets are smart devices that specialize in handling digital currencies.

39. Airdrop

The project sends digital currency to each user’s wallet address.

40. Mapping

Mapping is related to the issuance of blockchain currency and is a mapping between chains. For example, there are some blockchain companies that have not completed the development of the chain in the early stage. They rely on Ethereum to issue their own currency. The issuance and transactions of the early currency are all operated on Ethereum. With the development of the company, the company's own chain development has been completed. The company wants to map all the previous information on Ethereum to its own chain. This process is mapping.

41. Position

51. Long (long)

The buyer believes that the currency price will rise in the future, buys the currency, and waits for the currency price After rising, sell at a high price to take profits

52. Short position (short selling)

The seller believes that the currency price will fall in the future, and sells the currency he holds (or borrows it from the trading platform) (coin) sell, wait for the price of the currency to fall, buy at a low price to take profits

53. Open a position

Buy virtual currencies such as Bitcoin

54 . Cover the position

Buy Bitcoin and other virtual currencies in batches, for example: buy 1 BTC first, and then buy 1 BTC later

55. Full position

All funds are purchased at one time to buy a certain virtual currency

56. Rebound

When the currency price falls, the price rebounds and adjusts because it falls too fast

57 .Consolidation (sideways)

The price fluctuation is small and the currency price is stable

58. Yin fall

The currency price declines slowly

59. Diving (waterfall)

The currency price fell rapidly and to a large extent

60. Cutting meat

After buying Bitcoin, the currency price fell, as Avoid expanding losses and selling Bitcoin at a loss. Or after borrowing the currency to go short, the currency price rises, and you buy Bitcoin at a loss

61. Holding up

Expect the currency price to rise, but unexpectedly the currency price falls after buying; Or expect the currency price to fall, but unexpectedly the currency price rises after selling

62. Unwinding

After buying Bitcoin, the currency price fell, causing a temporary book loss, but then The currency price rebounded, turning losses into profits

63. Going short

After selling Bitcoin because of the bearish market outlook, the currency price continued to rise, and I failed to buy it in time, so I failed to make a profit. Gain profits

64. Overbought

The currency price continues to rise to a certain height, the buyer's power is basically exhausted, and the currency price is about to fall

65. Oversold< /p>

The currency price continues to fall to a certain low, the seller's power is basically exhausted, and the currency price is about to rise

66. Lure bulls

The currency price has been consolidating for a long time and has fallen. It is more likely that most of the short sellers have sold Bitcoin, and suddenly the short sellers pulled up the price of the currency, inducing many parties to think that the price of the currency will rise and buy one after another. As a result, the short sellers suppressed the price of the currency and locked up the long parties.

67. Short-selling

After buying Bitcoin, bulls deliberately suppress the price of the currency, making short sellers think that the price of the currency will fall and sell them one after another. As a result, they fall into the trap of bulls

< p>

68. What is NFT

The full name of NFT is "Non-Fungible Tokens", which is non-fungible tokens. Simply put, it is on the blockchain. An indivisible copyright certificate, it is mainly used to confirm and transfer the rights of digital assets. The difference from digital currency is that it is unique and indivisible. In essence, it is a unique digital asset.

69. What is the Metaverse

The Metaverse is a collection of virtual time and space, consisting of a series of augmented reality (AR), virtual reality (VR) and the Internet (Internet) Composed of digital currency, which carries the function of value transfer in this world.

70. What is DeFi

DeFi, the full name is Decentralized Finance, which is "decentralized finance" or "distributed finance". "Decentralized finance", as opposed to traditional centralized finance, refers to various financial applications based on open decentralized networks. The goal is to establish a multi-level financial system based on blockchain technology and cryptocurrency. As a basis, re-create and improve the existing financial system

71. Who is Satoshi Nakamoto?

72. Bitcoin is different from Q Coin

Bitcoin is a decentralized digital asset with no issuing entity. Q Coin is an electronic currency issued by Tencent. It is similar to electronic points. In fact,Not currency. Q Coin requires a centralized issuing institution. Q Coin can only be recognized and used because of the credit endorsement of Tencent. The scope of use is also limited to Tencent's games and services. The value of Q coins is entirely based on people's trust in Tencent.

Bitcoin is not issued through a centralized institution, but it is widely recognized around the world because Bitcoin can self-certify its trust. The issuance and circulation of Bitcoin are jointly accounted for by miners across the entire network, and are not A central authority is also needed to ensure that no one can tamper with the ledger.

73. What is a mining machine?

Taking Bitcoin as an example, a Bitcoin mining machine is a professional equipment that competes for accounting rights by running a large amount of calculations to obtain new Bitcoin rewards. It is generally composed of a mining chip, a heat sink and a fan, and only performs A single calculation program consumes a lot of power. Mining is actually a competition between miners for computing power. Miners with more computing power have a greater probability of mining Bitcoin. As the computing power of the entire network increases, it becomes increasingly difficult to mine bits with traditional equipment (CPU, GPU), and people have developed chips specifically for mining. The chip is the core part of the mining machine. The operation of the chip will generate a large amount of heat. In order to dissipate heat, Bitcoin mining machines are generally equipped with heat sinks and fans. Users download Bitcoin mining software on their computers, use the software to assign tasks to each mining machine, and then start mining. Each currency has a different algorithm and requires different mining machines.

74. What is quantitative trading?

Quantitative trading, sometimes also called automated trading, refers to the use of advanced mathematical models to replace human subjective judgments, which greatly reduces the impact of investor sentiment fluctuations and avoids extreme fanaticism or pessimism in the market. make irrational investment decisions. There are many types of quantitative trading, including cross-platform trading, trend trading, hedging, etc. Cross-platform trading means that when the price difference between different target platforms reaches a certain amount, sell on the platform with a higher price and buy on the platform with a lower price.

75. Blockchain asset over-the-counter trading

Over-the-counter trading is also called OTC trading. Users need to find their own counterparties and do not need to match the transaction. The transaction price is determined by negotiation between the two parties. The two parties can fully communicate through face-to-face negotiation or telephone communication.

76. What is a timestamp?

The blockchain ensures that each block is connected sequentially through timestamps. Timestamps enable every piece of data on the blockchain to have a time stamp. Simply put, timestamps prove when something happened on the blockchain and cannot be tampered with by anyone.

77. What is a blockchain fork?

Upgrading software in a centralized system is very simple, just click "Upgrade" in the app store. However, in decentralized systems such as blockchain, "upgrading" is not that simple, and may even causeBlockchain forks. Simply put, a fork refers to a disagreement when the blockchain is "upgraded", resulting in a fork in the blockchain. Because there is no centralized organization, every code upgrade of digital assets such as Bitcoin needs to be unanimously recognized by the Bitcoin community. If the Bitcoin community cannot reach an agreement, the blockchain is likely to form a fork.

78. Soft fork and hard fork

Hard fork means that when the Bitcoin code changes, the old nodes refuse to accept the blocks created by the new nodes. Blocks that do not comply with the original rules will be ignored, and miners will follow the original rules and create new blocks after the last block they verified. A soft fork means that old nodes are not aware of the changes to the Bitcoin code and continue to accept blocks created by new nodes. Miners may work on blocks they have no understanding of, or validation of. Both soft forks and hard forks are "backwards compatible" to ensure that new nodes can verify the blockchain from scratch. Backward compatibility means that new software accepts data or code generated by old software. For example, Windows 10 can run Windows XP applications. Soft forks can also be "forward compatible".

79. Classification and application of blockchain projects

Judging from the current mainstream blockchain projects, blockchain projects mainly fall into four categories: Category 1: Currency; The second category: platform category; the third category: application category; the fourth category: asset tokenization.

80. USDT against the US dollar

USDT is Tether USD, a token launched by Tether that is against the US dollar (USD). 1USDT=1 US dollar, users can use USDT and USD for 1:1 exchange at any time. Tether implements a 1:1 reserve guarantee system, that is, each USDT token will have a reserve guarantee of 1 US dollar, which supports the stability of the USDT price. The unit price of a certain digital asset is USDT, which is equivalent to its unit price in US dollars (USD).

81. Altcoins and alternative coins

Altcoins refer to blockchain assets that use the Bitcoin code as a template and make some modifications to its underlying technology blockchain, among which Those with technological innovations or improvements are also called alternative coins. Because the Bitcoin code is open source, the cost of plagiarism in Bitcoin is very low. You can even generate a brand new blockchain by simply copying the Bitcoin code and modifying some parameters.

96. What is a token?

The token economy is an economic system with Token as the only reference standard, which is equivalent to a pass. If you own Token, you have rights and interests, and you have the right to speak.

Big data is the means of production, AI is the new productivity, and blockchain is the new production relationship. Big data refers to a collection of data that cannot be captured, managed and processed within a certain time range using conventional software tools. It is a massive, high-growth and high-volume data set that requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. Diverse information assets. Simply understood, big data is massive data accumulated over a long period of time and cannot be obtained in the short term. Blockchain can be used as a way to obtain big data, but it cannot replace big data. Big data is only used as a medium running in the blockchain and has no absolute technical performance, so the two cannot be confused. (A simple understanding of production relations is labor exchange and consumption relations. The core lies in productivity, and the core of productivity lies in production tools)

ICO, Initial Coin Offering, initial public token issuance, is the first step in the blockchain digital currency industry. Crowdfunding. It is the most popular topic and investment trend in 2017, and the country launched a regulatory plan on September 4. Speaking of ICO, people will think of IPO, and the two are fundamentally different.

99. Five characteristics of digital currency

The first characteristic: decentralization

The second characteristic: having open source code

The third feature: independent electronic wallet

The fourth feature: constant issuance

The fifth feature: global circulation

100. What is decentralization?

It has no issuer, does not belong to any institution or country, and is a publicly issued currency designed, developed and stored on the Internet by Internet network experts.

100. What is measurement (scarcity)?

Once the total amount of issuance is set, it is permanently fixed and cannot be changed or exceeded at will.Global Internet surveillance is acceptable. Because the difficulty of mining and mining changes over time, the longer the time, the greater the difficulty of mining, and the fewer coins are mined, so it is scarce.

101. What is open source code?

The alphanumeric code is stored on the Internet. Anyone can find out the source code of its design, everyone can participate, can mine it, and it is open to the world.

102. What is anonymous transaction? Private wallet private?

Everyone can register and download the wallet online without real-name authentication. It is completely composed of encrypted digital codes. It can be sent and traded globally in real-time point-to-point without resorting to banks or any institutions. It cannot be traced by anyone without my authorization. ,Inquire.

A contract transaction refers to an agreement between a buyer and seller to receive a certain amount of an asset at a specified price at a certain time in the future. The objects of contract trading are standardized contracts formulated by the exchange. The exchange stipulates standardized information such as commodity type, transaction time, quantity, etc. A contract represents the rights and obligations of the buyer and seller.
