Ⅰ Consensus Mechanism of Blockchain
1. Goal of Blockchain Consensus Mechanism
What is Blockchain? Simply put, blockchain is a decentralized database, or it can be called a distributed ledger. Traditionally, all databases are centralized. For example, a bank's ledger is stored in the bank's central server. The disadvantage of a centralized database is that the security and accuracy of the data depend entirely on the database operator (i.e., the bank), because anyone who has access to the centralized database (such as bank employees or hackers) can destroy or modify the data in it.
Blockchain technology allows databases to be stored on thousands of computers around the world. Everyone’s ledger is synchronized through a peer-to-peer network, and anyone in the network can Once a user adds a transaction, the transaction information will be notified to other users through the network for verification and recorded in their respective ledgers. Blockchain gets its name because it is a data structure composed of blocks containing transaction information linked in an orderly manner from back to front.
Many people’s question about blockchain is that if each user has an independent ledger, does it mean that they can add to their own ledger? Arbitrary transaction information, and how can thousands of ledgers ensure the consistency of accounting? Solving the problem of accounting consistency is the goal of the blockchain consensus mechanism. The blockchain consensus mechanism aims to ensure that the data in all nodes in the distributed system are exactly the same and can reach agreement on a certain proposal (for example, a transaction record). However, due to the introduction of multiple nodes in a distributed system, various very complex situations will occur in the system; as the number of nodes increases, node failure or failure, network communication between nodes is interfered or even blocked, etc. In addition to common problems, solving various boundary conditions and unexpected situations in distributed systems also increases the difficulty of solving distributed consistency problems.
Blockchain can be divided into three types:
Public chain: full Anyone in the world can enter the system at any time to read data, send confirmed transactions, and compete for accounting in the blockchain. Public blockchains are generally considered "completely decentralized" because no one or institution can control or tamper with the reading and writing of data. Public chains generally encourage participants to compete for accounting through a token mechanism to ensure data security.
Alliance chain: Alliance chain refers to a blockchain in which several institutions jointly participate in management. Each institution runs one or more nodes, and the data in it only allows different institutions within the system to read, write and send transactions, and jointly record transaction data. This type of blockchain is recognizedIt is "partially decentralized".
Private chain: refers to a blockchain whose write permission is controlled by an organization or institution. The qualifications of participating nodes will be strictly restricted. Since the participating nodes are limited and controllable, private chains can often have extremely fast transaction speeds, better privacy protection, lower transaction costs, and are not prone to malicious attacks. , and can meet the necessary requirements of the financial industry such as identity authentication. Compared with centralized databases, private chains can prevent single nodes within an organization from deliberately concealing or tampering with data. Even if an error occurs, the source can be quickly discovered, so many large financial institutions are currently more inclined to use private chain technology.
2. Classification of blockchain consensus mechanisms
The difficulty of solving distributed consistency problems has given rise to several consensus mechanisms, each of which has its own advantages and disadvantages, and is also suitable for different environment and issues. The consensus mechanisms that are common knowledge include:
l PoW (Proof of Work) workload proof mechanism
l PoS (Proof of Stake) ) Equity/Equity Proof Mechanism
l DPoS (Delegated Proof of Stake) Share Authorization Proof Mechanism
l PBFT (Practical Byzantine Fault Tolerance) Practical Byzantine Fault Tolerance Algorithm
l DBFT (Delegated Byzantine Fault Tolerance) Authorized Byzantine Fault Tolerance Algorithm
l SCP (Stellar Consensus Protocol) Stellar Consensus Protocol
l RPCA (Ripple Protocol Consensus Algorithm) Ripple Consensus Algorithm
p>l Pool verification pool consensus mechanism
(1) PoW (Proof of Work) workload proof mechanism
< br />
1. Basic introduction
In this mechanism, every node on the network is using the SHA256 hash function (hash function) Calculate the hash value (hash sum) of a changing block header. Consensus requires that the calculated value must be equal to or less than a given value. In a distributed network, all participants need to continuously calculate the hash value using different random numbers until the goal is reached. When a nodeTo calculate the exact value, all other nodes must confirm with each other that the value is correct. Transactions in new blocks will then be verified to prevent fraud.
In Bitcoin, the above nodes that calculate hash values are called "miners", and the PoW process is called "mining". Mining is a time-consuming process, so incentives have been proposed (such as granting miners a small share of Bitcoin). The advantage of PoW is complete decentralization. Its disadvantage is the waste of resources caused by consuming a lot of computing power, the cycle of reaching consensus is also relatively long, and the consensus efficiency is low, so it is not very suitable for commercial use.
2. Application examples of cryptocurrency
Bitcoin and Litecoin. The first three phases of Ethereum (Frontier, Homestead, and Metropolis) all adopt the PoW mechanism, and its fourth phase (Serenity) will adopt the proof-of-stake mechanism. PoW is suitable for public chains.
Although the PoW mechanism has successfully proved its long-term stability and relative fairness, under the existing framework, using the "mining" form of PoW will consume A lot of energy. The energy it consumes is just to continuously perform SHA256 calculations to ensure fair workload, and has no other meaning of existence. The current transaction efficiency that BTC can achieve is about 5TPS (5 transactions/second). Ethereum is currently subject to the upper limit of the total amount of GAS in a single block, and the transaction frequency that can be achieved is about 25TPS, which is the same as the average thousand times per second and peak performance. There is a huge difference between VISA and MASTERCARD, which can achieve processing efficiency of 10,000 times per second.
3. Simple diagram understanding mode
(ps: The process of calculating hash values by A, B, C, and D is "mining". In order to reward the time cost, the mechanism will use a certain number of Bitcoins as incentives.)
(Ps: In PoS mode, your "mining" income is proportional to the age of your currency (number of coins * number of days), and has nothing to do with the computing performance of the computer. We can think that the accumulation of any probabilistic events is proof of work, such as gold mining. Assuming that the gold content of ore is p% mass, when you get a certain amount of gold, we can think that you must have dug 1/p mass of ore. And The more gold you get, the more reliable the proof is.)
(2) PoS (Proof of Stake) Equity/Proof of Equity Mechanism
1. Basic introduction
PoS requires people to prove ownership of the currency amount, and it is believed that people with a large amount of currency are less likely to attack the network. Selection based on account balance is very unfair, as the single richest person is bound to dominate the network, so many solutions have been proposed.
In the proof-of-stake mechanism, whenever a block is created, miners need to create a transaction called "coin rights", which will be determined according to a certain Proportionately sends some coins to miners in advance. Then the equity proof mechanism reduces the mining difficulty of nodes in equal proportions based on the proportion and time of tokens held by each node (coin age) according to the algorithm, so as to speed up the node's search for random numbers and shorten the time required to reach consensus.
Compared with PoW, PoS can save more energy and be more efficient. But since the mining cost is close to 0, it may be vulnerable to attacks. And PoS still essentially requires nodes in the network to perform mining operations, so it is also difficult to apply in the commercial field.
2. Application examples of digital currency
The more mature digital currencies under the PoS mechanism are Peercoin and NXT. Compared with PoW, the PoS mechanism saves energy and introduces the concept of "coin days" to participate in random operations. The PoS mechanism allows more currency holders to participate in the accounting work without the need to purchase additional equipment (mining machines, graphics cards, etc.). The computing power of each unit token is positively related to the length of time it is held. That is, the more tokens a holder holds and the longer the time, the greater the probability that the holder can sign and produce the next block. Once it signs the next block, the currency days held by the currency holder will be cleared and a new cycle will be re-entered.
PoS is suitable for public chains.
3. How to generate block signers
Under the PoS mechanism, Because the signers of blocks are randomly generated, some currency holders will hold tokens for a long time and in large amounts to obtain a greater probability of generating blocks, and to clear as many of their "coin days" as possible. Therefore, the number of circulating tokens in the entire network will decrease, which is not conducive to the circulation of tokens on the chain, and prices will be more susceptible to fluctuations. becauseThere may be a situation where a small number of large investors hold most of the tokens in the entire network, and the entire network may become more and more centralized as the running time increases. Compared with PoW, the cost of doing evil under the PoS mechanism is very low, so for forking or double-spending attacks, more mechanisms are needed to ensure consensus. Under stable conditions, approximately 12 transactions can be generated per second, but due to network delays and consensus issues, it takes about 60 seconds to fully broadcast the consensus block. In the long run, the speed of generating blocks (i.e. clearing "coin days") is much lower than the speed of network propagation and broadcasting. Therefore, under the PoS mechanism, it is necessary to "limit the speed" of generated blocks to ensure the stability of the main network. run.
4. Simple diagram understanding mode
(PS: The more “shares” you own, the easier it is for you to obtain account rights. It refers to how much currency you get, which depends on the workload you contribute to mining and the performance of your computer. The better, the more mines will be allocated to you.)
(In a pure POS system, such as NXT, there is no mining process, and the initial equity The distribution has been fixed, and then only the equity is transferred among traders, very similar to stocks in the real world.)
(3) DPoS (Delegated Proof of Stake) ) Share authorization certification mechanism
1. Basic introduction
Due to various disadvantages of PoS , thus the DPoS (Delegated Proof of Stake), the first equity representation mechanism pioneered by BitShares, came into being. The core element of the DPoS mechanism is election. Holders of each system's native tokens can participate in elections in the blockchain, and the balance of the tokens they hold is the voting weight. Through voting, shareholders can elect board members and express their attitudes on issues related to the development direction of the platform, all of which form the basis of community autonomy. In addition to voting in elections themselves, shareholders can also vote on their behalf by authorizing their election votes to other accounts they trust.
Specifically, DPoS was invented by the Bitshares project team. Stakeholders elect their representatives to generate and verify blocks. DPoS is similar to a modern corporate board of directors system. The BitShares system refers to token holders as shareholders, and shareholders vote to elect 101 representatives. These representatives are then responsible for generating and verifying blocks. If a currency holder wants to be called a representative, he must first use hisRegister your public key on the blockchain and obtain a unique identity identifier with a length of 32 bits. Shareholders can vote on this identifier in the form of transactions, and the top 101 votes will be selected as representatives.
Representatives take turns to generate blocks, and the profits (transaction fees) are equally divided. The advantage of DPoS is that it greatly reduces the number of nodes participating in block verification and accounting, thereby shortening the time required for consensus verification and greatly improving transaction efficiency. From a certain perspective, DPoS can be understood as a polycentric system, which has the advantages of both decentralization and centralization. Advantages: It greatly reduces the number of nodes participating in verification and accounting, and can achieve second-level consensus verification. Disadvantages: Voting enthusiasm is not high, and most token holders do not participate in voting; in addition, the entire consensus mechanism still relies on tokens, and many commercial applications do not require the existence of tokens.
The DPoS mechanism requires that before generating the next block, it must be verified that the previous block has been signed by a trusted node. Compared with PoS's "National Mining", DPoS uses a system similar to the "Congress" to directly select trusted nodes, and these trusted nodes (i.e. witnesses) exercise power on behalf of other currency holders. Witnesses Nodes are required to be online for a long time, thus solving a series of problems such as delays in block production that may be caused by PoS block signers not always being online. The DPoS mechanism can usually reach a transaction speed of 10,000 transactions per second, and can reach the level of 100,000 seconds when the network delay is low, which is very suitable for enterprise-level applications. Because Gongxinbao Data Exchange has high requirements for data transaction frequency and long-term stability, DPoS is a very good choice.
2. Institutions and systems under the share authorization certification mechanism
The board of directors is the authority of the blockchain network. The candidates for the board of directors are elected by system shareholders (i.e. currency holders). Board members have the right to initiate motions and vote on motions.
One of the important responsibilities of the Board of Directors is to adjust the variable parameters of the system as needed. These parameters include:
l Fee related: rates for various transaction types.
l Authorization related: parameters related to charges and subsidies for third-party platforms that access the network.
l Block production related: block production interval, block reward.
l Identity review related: review and verify the information of abnormal institutional accounts.
l At the same time, matters related to the interests of the Board of Directors will not be set by the Board of Directors.
inIn the Finchain system, witnesses are responsible for collecting various transactions broadcast when the network is running and packaging them into blocks. Their work is similar to miners in the Bitcoin network. In the Bitcoin network using PoW (proof of work), A lottery method in which the probability of winning depends on hash power determines which miner node produces the next block. In a financial chain network that adopts the DPoS mechanism, the number of witnesses is determined by voting by the board of directors, and the candidates for the witnesses are determined by voting by currency holders. The selected active witnesses package transactions and produce blocks in order. After each round of block production, the witnesses will randomly shuffle the cards to determine the new order before entering the next round of block production.
3. Application examples of DPoS
Bitshares uses DPoS. DPoS is mainly suitable for alliance chains.

(4) PBFT (Practical Byzantine Fault Tolerance) Practical Byzantine Fault Tolerance Algorithm
1. Basic introduction
PBFT is an algorithm based on strict mathematical proof, which requires three stages of information interaction and local consensus to achieve the final unanimous output. The three stages are pre-prepare, prepare, and commit. The PBFT algorithm proves that as long as there are more than 2/3 normal nodes in the system, it can ensure that a consistent consensus result can be output in the end. In other words, in a system using the PBFT algorithm, it can tolerate no more than 1/3 of the total number of nodes in the system (including nodes that intentionally mislead, intentionally damage the system, time out, repeatedly send messages, forge signatures, etc., also known as " Byzantium" node).
2. Application examples of PBFT
The famous alliance chain Hyperledger Fabric v0.6 uses PBFT, and v1.0 launched an improved version of PBFT, SBFT. PBFT is mainly suitable for private chains and consortium chains.
3. Simple diagram understanding mode
The above figure shows a simplified PBFT protocol Communication mode, where C is the client, 0 – 3 represents the service node, where 0 is the master node and 3 is the fault node. The basic process of the entire protocol is as follows:
(1) The client sends a request to activate the service operation of the master node;
(2) When the master node receives the request, it starts a three-phase protocol to broadcast the request to each slave node;
(a) Sequence number allocation phase, the master node assigns a sequence number n to the request, broadcasts the sequence number allocation message and the client's request message m, and will construct a pre-prepare message to each slave node;
(b) In the interaction phase, the slave node receives the pre-prepare message and broadcasts the prepare message to other service nodes;
(c) In the sequence number confirmation phase, after each node verifies the request and sequence in the view, it broadcasts the commit message, executes the received client request and responds to the client.
(3) The client waits for responses from different nodes. If m+1 responses are the same, the response is the result of the operation;

(5) DBFT (Delegated Byzantine Fault Tolerance) authorized Byzantine fault tolerance algorithm
1. Basic introduction
DBFT is based on PBFT. In this mechanism, there are two types of participants, one is the "super node" who specializes in accounting , one is an ordinary user who does not participate in accounting in the system. Ordinary users vote for super nodes based on the proportion of their equity holdings. When a consensus (accounting) needs to be passed, a spokesperson is randomly selected among these super nodes to formulate a plan, and then other super nodes use Byzantine fault tolerance to algorithm (see above), that is, the principle of majority submission. If more than 2/3 of the super nodes agree with the speaker plan, a consensus is reached. This proposal becomes the final published block, and the block is irreversible, and all transactions in it are 100% confirmed. If a consensus proposal has not been reached within a certain period of time, or if illegal transactions are discovered, other super nodes can reinitiate the proposal and repeat the voting process until a consensus is reached.
2. DBFTApplication examples
NEO, a domestic cryptocurrency and blockchain platform, is the developer and adopter of the DBFT algorithm.
3. Simple diagram understanding mode
Assume that there are only four super nodes in the system voted by ordinary users. When a consensus needs to be passed, the system will randomly select one of the representatives to speak. People make plans. The spokesperson will hand over the prepared plan to each representative. Each representative will first determine whether the speaker's calculation results are consistent with their own records, and then discuss with other representatives to verify whether the calculation results are correct. If 2/3 of the representatives unanimously agree that the calculation results of the speaker's plan are correct, then the plan is passed.
If less than 2/3 of the representatives reach a consensus, a new speaker will be randomly selected and the above process will be repeated. This system is designed to protect the system from leaders who are unable to function.
The above figure assumes that all nodes are honest and reach 100% consensus, and plan A (block) will be verified.
Given that the spokesperson is a randomly selected representative, he may be dishonest or malfunctioning . The above figure assumes that the spokesperson sends malicious messages to 2 of the 3 representatives (scenario B), and at the same time sends a correct message to 1 representative (scenario A).
In this case, the malicious information (Option B) cannot pass. The calculation results of the representatives in the middle and on the right were inconsistent with those sent by the spokesperson, so they could not verify the plan drawn up by the spokesperson, causing the two people to reject the plan. The representative on the left received correct information that was consistent with his own calculation results, so he was able to confirm the plan and successfully completed a verification. However, this plan still failed to pass because less than 2/3 of the representatives reached a consensus. A new spokesperson will then be randomly selected and the consensus process will begin again.
The above picture assumes that the speaker is honest, but One of the representatives experienced an anomaly; the representative on the right sent incorrect information to the other representatives (B).
In this case, the correct information (A) formulated by the speaker can still be verified, because both the honest representatives on the left and the middle can verify that the correct information (A) formulated by the spokesperson Prepared by the spokespersonplan and reached a 2/3 consensus. The representative can also determine whether the speaker is lying to the node on the right or the node on the right is being dishonest.
(6) SCP (Stellar Consensus Protocol) Stellar Consensus Protocol
1. Basic introduction
SCP is a consensus algorithm developed and used by Stellar (a decentralized global payment protocol based on the Internet). It is based on the Federated Byzantine Agreement ( Federated Byzantine Agreement). Although traditional non-federated Byzantine protocols (such as PBFT and DBFT above) ensure that consensus can be reached through distributed methods and achieve Byzantine fault tolerance (can tolerate at most failed nodes that do not exceed 1/3 of the total number of nodes in the system), it is a Centralized system - The number and identity of nodes in the network must be known and verified in advance. The difference of the Federated Byzantine Agreement is that it can be decentralized and Byzantine fault-tolerant at the same time.

(7) RPCA (Ripple Protocol Consensus Algorithm) Ripple Consensus algorithm
1. Basic introduction
RPCA is Ripple (an Internet-based Open source payment protocol, which can realize decentralized currency exchange, payment and settlement functions) consensus algorithm developed and used. In Ripple's network, transactions are initiated by the client (application) and broadcast to the entire network through the tracking node or validating node. The main function of the tracking node is to distribute transaction information and respond to client ledger requests. In addition to all the functions of the tracking node, the verification node can also add new ledger instance data to the ledger through the consensus protocol.
Ripple's consensus occurs between verification nodes. Each verification node is pre-configured with a list of trusted nodes, called UNL (Unique Node). List). Nodes on the list can vote on the transaction. The consensus process is as follows:
(1) Each verification node will continuously receive transactions sent from the network, and communicate with the local accountAfter this data is verified, illegal transactions will be discarded directly, and legal transactions will be summarized into a transaction candidate set. The transaction candidate set also includes transactions left over from the previous consensus process that could not be confirmed.
(2) Each verification node sends its own transaction candidate set as a proposal to other verification nodes.
(3) After the verification node receives a proposal from other nodes, if it is not from a node on UNL, it will ignore the proposal; if it is from a node on UNL, it will compare it with the proposal. Transaction and local transaction candidate set, if there is the same transaction, the transaction gets one vote. Within a certain period of time, when a transaction receives more than 50% of the votes, the transaction enters the next round. Transactions that do not exceed 50% will be left for the next consensus process to be confirmed.
(4) The verification node sends transactions with more than 50% of the votes as proposals to other nodes, and at the same time increases the threshold of the required votes to 60%, repeating steps (3) and (4) until the threshold Reach 80%.
(5) The verification node formally writes the transactions confirmed by 80% UNL nodes into the local ledger data, which is called the last closed ledger, which is the last (latest) status of the ledger.
In Ripple's consensus algorithm, the identities of participating voting nodes are known in advance. Therefore, the algorithm is more efficient than anonymous consensus algorithms such as PoW. Transactions The confirmation time only takes a few seconds. This also determines that the consensus algorithm is only suitable for alliance chains or private chains. The Byzantine Fault Tolerance (BFT) capability of the Ripple consensus algorithm is (n-1)/5, which means it can tolerate Byzantine errors in 20% of the nodes in the entire network without affecting the correct consensus.

(8) POOL verification pool consensus mechanism
Pool verification pool The consensus mechanism is a mechanism developed based on traditional distributed consensus algorithms (Paxos and Raft). The Paxos algorithm is a consensus algorithm based on message passing and highly fault-tolerant proposed in 1990. In the past, Paxos has been the standard for distributed protocols, but Paxos is difficult to understand and even harder to implement.now. Raft is a consensus algorithm released in 2013 that is simpler than Paxos and can realize the problems solved by Paxos. The process of reaching consensus in Paxos and Raft is like an election. Candidates need to convince the majority of voters (servers) to vote for them and follow their actions once selected. The difference between Paxos and Raft lies in the specific process of election. The Pool verification pool consensus mechanism is based on these two mature distributed consensus algorithms, supplemented by a data verification mechanism.
II Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results
Zhang Ping, chief engineer of the Cyberspace Administration of Hebei Provincial Committee, introduced, Blockchain is one of the hot spots of this expo. The "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year clarified the development goals of Hebei Province's blockchain technology and industrial application - By the end of 2022, there will be 20 leading companies and leading companies in blockchain-related fields in Hebei Province, cultivating a number of blockchain application products, and striving to create 1-3 nationally renowned blockchain brands and form 3 regionally influential brands.

IV How to define blockchain and what are the application scenarios of blockchain?
Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
In terms of the definition of blockchain technology, the United StatesChinese scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized database in her book "Blockchain: A New Economic Blueprint and Introduction".
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past has become classic, while others said To say that everything is hype is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the thirdFang’s electronic signature platform eShanbao revealed the latest progress in blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao’s new intellectual property protection solution based on timestamp + blockchain starts from the user’s real-name authentication and solidifies the information generated during the real-time solidification process. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
Through the following limited cases, I hope everyone can understand the actual performance of blockchain technology, thereby stimulating interest in such solutions.
1. Administrative Services
Over the centuries, the roles and responsibilities of public administration have not changed significantly – or rather, what has changed dramatically is actually the size of the data and the specific ways in which public agencies handle it. While various digital technologies already exist to help collect and process data, issues such as anonymization, portability and the immutability of large amounts of data remain.However it was not resolved.
Sasha Ivanov, founder, entrepreneur and CEO of Waves Platform and Vostok projects, said, "What the public administration currently lacks is a more convenient user experience (UX) for data use. To improve the user experience , we should introduce some kind of layer to it that acts as a trusted public environment that is transparent and can store data anonymously and immutably."
Governments are working on this by launching the U.S. Federal agency and enterprise-level initiatives such as the Federal Blockchain Initiative are gradually confronting the existence of such problems. The United States held its first federal government blockchain forum in July 2017, and the U.S. General Services Administration currently has more than 200 related use case repositories. Ivanov explained, “Distributed systems can really help us build such a reliable environment, improve our big data work, and even integrate all emerging technologies – including artificial intelligence and the Internet of Things. In fact, , whenever we face any kind of technology, it always embodies the sum of certain other technologies."
Now, the system supported by the blockchain can actually work - this This view has been unanimously recognized by all experts and has become the most important theoretical basis. In other words, what we need to do next is create more production-ready solutions.
2. Payment services
The government needs to process transactions, many of which involve the exchange of funds with citizens. Blockchain technology has huge potential application value in reducing the cost of fund transfers - including using new blockchain-based cryptocurrencies as intermediate transaction carriers, or using blockchain as a means of fund transfer, etc. Once a perfect solution is discovered, the business opportunities will be endless - especially for those who need to conduct frequent cross-border or Internet transactions.
The Jasper project was developed by the Bank of Canada to help it further think about how central banks and other financial institutions should implement payment operations between different banks based on distributed ledgers. The Bank of Canada has also developed its own digital currency variant, “CAD Coin,” to test the feasibility of using a national currency on top of the blockchain.
This project brings to an interesting conclusion that we should say no to proof-of-work public chain systems. In a paper titled "Project Jasper: Is a Distributed Batch Payment System Feasible?" the author observed that "Proof-of-work systems are not suitable for such large transaction processing systems because they assume that all transactions in the system are There is a need for openness and observability to a certain extent.”
3. Digitization and intellectual property
Governments are responsible for maintaining copyright records and databases. These records prove ownership of intellectual property. The blockchain-based system allows artists of all types,Performers and writers can time-stamp their work and theoretically detect copyright infringements and even keep a permanent record of their rights. In fact, many governments have already taken important exploratory steps in this direction.
Iran recently announced that it will deploy this technology. "Iran Financial Tribune" quoted Morteza Mousavian as saying that "the Digital Media Department of the Ministry of Culture has reached an agreement with a blockchain company to jointly design a system that can be used to protect online copyrights." He also added that "the relevant procedures will It will soon be released to users in an easy-to-use format."
This work is still in the early exploratory stages, but it offers enterprise customers the possibility of preserving records through replication technology. From a theoretical level, companies can use blockchain solutions to conduct financial accounting and discover errors in real time.
4. Welfare distribution
The government has the responsibility to create a level playing field for citizens. Citizens who are chronically poor or economically disadvantaged certainly need government support and assistance to ensure that they are able to sustain themselves and develop. However, welfare distribution is neither simple nor often straightforward. Problems such as corruption and impersonation have been wreaking havoc on various distribution channels within government schemes.
In China, the National Council of Social Security Fund is conducting early research on how to use blockchain technology to improve the delivery of national benefits to citizens. At the same time, India is also taking action. Andhra Pradesh and Telangana are already using blockchain to support their civilian resource supply systems.
It is said that many companies, including Microsoft, are also considering using the same technology. These solutions, which will touch individual employees and functional roles, are expected to gradually appear in small businesses in the near future.
5. Bidding activities
In order to build public infrastructure or provide related services, the government hopes to achieve economies of scale and competitive gains through bidding as much as possible. However, the bidding process is often not fair or transparent. Public procurement has long been a major scene of rampant corruption around the world. Transparency International noted that “many governments will award project contracts to a certain supplier in the absence of fair competition. This allows companies with greater political resources to improperly win over competitors; or companies in the same industry Bids will be negotiated in advance between companies, ensuring that each company gets a share of the tender. This will significantly increase the cost of delivering services to the public - we have found that corruption issues can increase project costs by 50%."
So, how can blockchain technology solve the tendering problem? According to Ivanov, “Unlike decentralized centralized systems, independent ledgers powered by blockchain will be able to improve tendering.Or any other financial process that needs to be tracked for transparency. The intervention of blockchain technology will help track the use of funds and ensure that they are paid out as expected and within the allowed time. ”
Currently, Japan’s Ministry of Interior and Communications has announced a blockchain-based bidding system, which means that in industries with serious collusion problems, small and medium-sized enterprises are expected to usher in a more transparent bidding method and Brighter development prospects.
Although quite a few of the cases mentioned previously are far from finalized, they do provide many possibilities for enterprises and governments. Of course, the key lies in implementation; and we All this should also be viewed with optimism, that is, although blockchain technology is often misunderstood by people, it is and will eventually find a direction in which it can exert its own energy!
In layman's terms, blockchain is like There are more than a dozen beacon towers on the Great Wall. If an enemy comes at one place, they will send out smoke. The other beacon towers will know about it and enter a defensive state together. In technical language, it is a distributed ledger, and each node will keep accounts separately. The failure of a single node will not affect the entire network.
How is this distributed network different from the distributed servers of Google Network? Google Network and others The distributed servers still belong to the Google network and are controlled by their central scheduling algorithm. The distributed nodes in the blockchain do not know each other and have no legal affiliation. If you want to go offline and shut down That's fine, but because of the currency rewards, there will always be people who will start up as new nodes to support this network.
After the popular and technical explanation, I hope You already understand. Then the first application scenario is finance. I put the money in Alipay. If Alipay doesn't recognize it one day, there is nothing you can do. But on the blockchain, it is useless if a node does not recognize it. Because other nodes still have my records. The second one is the contract. Nowadays, contracts are signed on paper, which is easy to forge, but it cannot be forged if it is placed on the blockchain.
There are more application scenarios. It is recommended to check the top 100 digital Huobi online to understand the corresponding projects behind them and become a blockchain expert.
Area Blockchain technology was first used in Bitcoin. Blockchain provides a reliable and credible means of organizing data for cross-subject business scenarios. JD.com is essentially a supply chain company, and blockchain technology will first be used in the supply chain In many scenarios.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
Currently, there are more calls for it. The highest application industry is the financial industry.
The application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to conduct full traceability of some products sold. ConsumersPurchased goods can be traced back to their origin. There are also many blockchain applications in the digital advertising industry. Since digital advertising traffic fraud causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
What is blockchain If you use non-technical terms to explain blockchain, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone, so In the Internet, a place where data and information are exploding, having such a place would be like a magical treasure.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
Both parties involved in the transaction do not need to know who the other party isNo one needs a third party for trust endorsement. They only need to trust the common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15,728.64 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
IV It’s 2021, what will be the development trend of my country’s blockchain technology in the future
Domestic blockchain technology has been conceptualized a few years ago , has now been widely used in actual business scenarios, such as the rice we eat, the QR code on the packaging
Traceability is the application of blockchain technology. Companies like Shanghai Wanglian Technology entered the market earlier and are currently developing very well.
VI The significance of the establishment of the Blockchain Alliance
The 2018 Global Media Blockchain Summit was held on the 19th at the Financial Hall of the Hong Kong Stock Exchange. Many media attending the meeting focused on the development prospects of blockchain , industry trends and other topics, they made suggestions on deepening media blockchain cooperation and promoting the healthy development of the industry, and jointly announced the establishment of the Global Media Blockchain Alliance.
According to reports, the alliance will provide an open access mechanism for media members, integrate resources, and create a trustworthy media blockchain platform. At the meeting, the Global Media Blockchain Alliance released the "Hong Kong Initiative", advocating that media disseminate advanced concepts, encourage ecological innovation, and continuously provide high-grade, high-quality information and services in the dissemination of information in the blockchain field.
Yu Guoming, Executive Dean of the School of Journalism and Communication of Beijing Normal University, pointed out at the summit that only through full development of media blockchain can a more sound and good media ecosystem be formed. Mainstream media must consciously assume social responsibilities in the development of media blockchain and become organizers and builders to promote technological progress and business innovation.
Ding Laibin, secretary-general of the Global Media Blockchain Alliance, said that blockchain technology is expected to bring new changes to society and its healthy development needs to be protected. In terms of public opinion supervision in the blockchain field, the media should give full play to its role in exploring the value of the industry, combating industry fraud, and contributing to the development of the blockchain industry.

Ⅶ The reason why the world blockchain organization does not have the right to issue ICO licenses and exchange licenses
But The WBO related page shows, "This organization is not in consultative status with ECOSOC", which means that the WBO has no affiliation with the United Nations.
The above-mentioned industry insiders said that non-governmental organizations (NGOs) are private and autonomous, which means that such organizations are institutionally independent from the government. They are not part of the government system. NGOs are engaged in the issuance of licenses and The license issuance business is unheard of in the industry. The person said that judging from the type and content of services provided by WBO, it is far different from NGOs and more like a government regulatory department.
He said that the registration threshold for NGOs in the United Nations is actually very low, but there are some requirements in terms of organizational form. According to United Nations Resolution 1296, if an NGO wants to register with the United Nations, its members must adopt a democratic approach. To participate in organizational activities, there should be a democratic decision-making mechanism, arrangements for accountability mechanisms and transparency of the decision-making process, and information on its budget and funding sources should be submitted to the United Nations.
The industry insider said that NGOs are still on the fringes of the existing international system, and their influence on major decisions is limited. However, precisely because they can be registered with the United Nations, they are used as endorsement tools by many organizations and individuals.
It is understood that a similar NGO organization appeared in China as early as 2017. The organization is called the Global Asset Digital Cryptocurrency Committee (WADCC), claiming to be a United Nations first-level international organization and becoming a member of the Economic and Social Council. It is the first global super-sovereign third-party financial regulatory agency (NGO) under the Council. However, according to Synchronous Financial Inquiry, WADCC, like WBO, has no affiliation with the United Nations and is only registered with the United Nations Department of Social and Economic Affairs.
VIII Blockchain opens the "Great Copyright Era" with value
With the development of the Internet, the digitalization process of the cultural industry has accelerated, and traditional copyright technology has been unable to meet the needs of copyright protection. The industry believes that in order to cope with the copyright protection challenges brought about by digital development, in addition to national policy guidance, the application of new technologies such as blockchain and big data will also play an important role. Recently,Xinhua News Agency China Picture Group stated that it will join hands with the DCI system to create a national image copyright service platform that integrates new technologies such as blockchain and digital watermarking.
In fact, in recent years, the country has continuously introduced various policies to support the development of the blockchain industry and encourage the innovative application of blockchain technology.
In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which for the first time included blockchain into the category of new technologies and made a cutting-edge layout.
On March 13, 2021, the "Fourteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals for 2035" was announced, and blockchain was listed as one of the seven digital economies. One of the key industries.
On July 16, 2021, the People's Bank of China released the white paper "Research and Development Progress of China's Digital RMB". Data shows that as of June 30, 2021, there have been more than 1.32 million digital RMB pilot scenarios, covering Living payment, catering services, transportation, shopping consumption, government services and other fields.
Recently, there is constant news about the positive development of the copyright industry and the innovation and development of blockchain technology. First, the China Copyright Protection Center will cooperate with Huawei to build my country's independently innovative DCI (Digital Copyright Identifier, Digital Copyright Unique Identifier) system and create a new ecosystem for the Internet copyright industry based on blockchain technology; second, Xinhua News Agency China Picture Group said , will join hands with the DCI system to jointly explore innovative research in the field of image content copyright in the 5G era, build a national image copyright service platform, and jointly build a new ecosystem for Internet visual copyright transactions.
The "Blockchain Digital Copyright Asset Transaction" channel jointly built and promoted by Alibaba Auction and Xinbian Chain was also launched nationwide recently and started previewing. The Alibaba auction platform is an innovative application of blockchain technology in the digital copyright industry. According to reports, the "Blockchain Digital Copyright Asset Transaction" project provides copyright owners engaged in literature, games, animation, music, art, etc. with the verification and on-chain transactions of digital works based on the "New Version Chain". The copyright of the work generates a unique digital copyright asset certificate in the "New Edition Chain". After the transaction, the legal holder of the copyright asset certificate will have all rights except the signature right of the digital work.
It is worth noting that the national image copyright service platform created this time will use new technologies such as blockchain, image invisible digital watermarks, network-wide image copyright detection, big data, and artificial intelligence. The industry believes that digital watermark technology can currently be used in eight scenarios, including radio and television content monitoring, media asset retrieval, film and television drama review and leakage prevention, advertising monitoring and statistics, movie projectors, Internet copyright protection, military information confidentiality, and IP product anti-counterfeiting. , the cumulative market size exceeds 2 billion yuan. Absolute technology and resourcesThe advantages are obvious, and the revenue scale of digital watermarking business is expected to expand significantly in the future.
Blockchain naturally solves the ownership confirmation problem in the information storage process based on mathematical principles. The recording, transmission and storage results of copyright information are all effective and credible. Once produced, the information recorded in the blockchain will be permanently recorded and cannot be tampered with. Only by possessing more than 51% of the computing power of the entire network can it be possible to modify the relevant copyright information.
In traditional intellectual property rights protection activities, a series of phenomena such as low execution efficiency of third-party agencies, difficulty in obtaining evidence, high costs, low compensation, and long cycle are common. In the information exchange and interconnection in the blockchain global network, efficiency can be greatly improved without the need for third-party processing. Generally speaking, blockchain solves the problem of being unable to tamper with registration time and content, while digital watermark technology solves the problem of providing evidence.
Relevant personnel of Hanbang Hi-Tech once said: "I found that someone pirated my content and included my watermark. This can provide evidence to prove the problem of piracy and copyright confirmation." Analysis by industry insiders It is pointed out that if watermarks are put on the chain and blockchain + digital watermarks are combined, the core pain points of cumbersome confirmation of rights in the original copyright protection technology can be perfectly solved, and it has high technical value.
Blockchain is closely related to our future. It is an imaginative concept. Many people think that blockchain is only related to digital currency, but actual exposure to blockchain may occur more in: health codes, online ride-hailing, stock trading... In fact, blockchain and its technology Derivative applications can be said to be the hottest emerging industry at the moment.
Blockchain cannot represent the future, but its future has great possibilities. Regarding the application scenarios of blockchain technology in copyright protection, what still needs to be done is to conduct in-depth research on the core technology of blockchain and understand the application nature of blockchain-enabled industries. The application of technology will be in place, the process will be standardized, the information security on the chain will be solved with focus, and it will be truly and effectively implemented in the physical field, so that the future industrial blockchain will usher in a new era of rapid development.
