A. How to manage national digital currency

1. Establish the theory of “common votes” and face the role of digital currency

< p> To sort out the meaning of digital currency in different contexts, it can be considered that the essence of digital currency is: a new equity certificate and distribution mechanism generated under the new organizational method based on blockchain in the digital economy era.

However, the term digital currency is rich in meaning, but it cannot accurately express this meaning. In fact, what blockchain brings is more conceptual innovation, which is essentially the embodiment of the concept of crowdfunding. The so-called digital currency is the return given after attracting voluntary investment from outside the system. This return realizes value through the operation of the blockchain system.

The owners and system participants of this "return" are both contributors (investors) and users (consumers) of the blockchain system, and they are also based on democratic participation. Decision makers (managers) of the blockchain system. This trinity of features fully realizes the value of crowdfunding.

In order to use the crowdfunding system to guide the healthy development of the blockchain industry, return to its roots, and correct chaos, the author proposed the "Coken" theory. "Co-voting" is a shared distribution mechanism on the blockchain that integrates investors, consumers and managers. It can also empower, confirm and empower data, and can stimulate new momentum for the digital economy with data as the core. .

For digital currency governance, "shared votes" is more important because it points out that the prospect of digital currency development returns to the original intention, releases the driving force of technological innovation, and serves the real economy. In the governance of digital currency, the "shared vote" theory should be applied, the value of digital currency in the digital economy era should be faced squarely, and the healthy development of digital currency should be guided.

2. Establish a legal chain and use the chain to govern the chain

Digital currency, as an incentive tool on the blockchain, has innovative significance, and its regulation needs to go beyond traditional thinking. To effectively regulate blockchain and digital currencies, it is also necessary to introduce blockchain technology as a tool to establish a legal chain and use chains to govern chains.

Blockchain-based regulatory systems will help improve the effectiveness of management. Management technology based on blockchain technology can solve the problem of dual failures of the government and the market, and take an organic management path that takes into account the characteristics of the technology itself. Only by making better use of technological governance can we effectively deal with the risks and challenges brought about by new technologies.

3. Use the trading platform as a starting point to convey policy intentions

Overall, my country’s management of digital currencies needs to continue to be strengthened, and there is still a gap between social reality and management goals. Despite the distance, some trading platforms are still very active in our country, and managers and the managed maintain a delicate balance.

The trading platform is currently the key and leader of the entire digital currency. It almost controls the voice of the entire digital currency industry. Managing the trading platform effectively can effectively convey policy intentions to digital currency market participants. It should be done in detail. At the management and operational level, we need to grasp its impact on society and the difficulty of implementation.

On the one hand, top trading platforms should be managed under the guidance of the principle of proportionality and strict management requirements are put forward;

On the other hand, small and medium-sized trading platforms should strictly enforce the law. A large number of operators of small and medium-sized trading platforms have a small number of operators and low professionalism. Criminals regard investors' principal as their target, and those involved in illegal and criminal activities must be dealt with resolutely in accordance with the law.

B. What is blockchain technology? What are the core components of blockchain technology?

What is blockchain technology? What are the core components of blockchain technology?

What is blockchain technology:
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
The core components of blockchain technology:
Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
The first one is called distribution A type of ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction and can also jointly testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
The second one is called asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with authorization from the data owner. This ensures data security and personal privacy.
The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to determine the validity of a record. This is not only a means of identification, but also a way to preventmeans of tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. [8]
Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
The last technical feature is called smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.
In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

What is the core layer of blockchain technology?

Chongqing Jinwowo Analysis: The consensus mechanism is the core of blockchain technology. The consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, and also determines other users’ views on the blockchain. The degree of trust in online data

What is the core component of blockchain technology?

Analysis by Chongqing Jinwowo: Blockchain technology consists of three core technologies: consensus mechanism, common defense mechanism, and distributed storage.
The three core technologies are supported by machine trust, that is, through the support of network technology, breakthroughs in difficult problems such as point-to-point transactions, decentralization, non-tampering of recorded information, irreversible transactions, and information encryption are achieved through network technology support.

What are the advantages of blockchain technology? Classification of blockchain technology?

The development of blockchain technology is becoming more and more prosperous with the continuous expansion of applications. This powerful development force coming from the needs of various industries has caused rapid changes in blockchain technology, allowing various industries to achieve great results. The results are attracting more and more attention, and professional technology and resources are constantly concentrated in this industry, thus bringing the development of blockchain technology to a new stage, and the impact of this development of blockchain technology has also much attention.
When talking about blockchain technology, Bitcoin has to be mentioned. As many people know, the electronic currency Bitcoin does notIt does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.
How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.
"Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a 'machine that creates trust.'" Bubi Company It is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.
The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it has a time stamp that cannot be tampered with. It can effectively solve problems such as data tracking and information anti-counterfeiting.
Will it become the next trend of Internet finance?
Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.
In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems and "anti-money laundering" "wait.
"The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. It has various functions for payment, clearing, transaction, confirmation of rights, etc. A profound impact," Li Yan said.
Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the rules of the existing financial system.improvements and build a shared and win-win financial development ecosystem.
Blockchain technology will affect many industries
"Blockchain technology has been widely used in the era of big data." Li Yan said frankly that in addition to the Internet financial field, blockchain technology has been used in many industries. It has been applied in many fields and has shown great prospects.
For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.
In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.
"Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any production and life that lacks trust In all fields, blockchain technology will have its place."
The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries. This The impact of this driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.

What is blockchain technology? What does blockchain technology mean?

The so-called blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization. , open and transparent, allowing everyone to participate in database records.
Explained in layman’s terms: If the database is assumed to be a ledger, reading and writing the database can be regarded as a bookkeeping behavior. The principle of blockchain technology is to find out the fastest and best bookkeeping within a period of time. This person will keep accounts, and then send this page of information to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.

What is the core technology of Jinwowo blockchain technology?

Chongqing Jinwowo analyzes the core technologies of blockchain technology as follows:
Distributed ledger technology, asymmetric encryption technology and smart contracts.

What is the core of Jinwowo blockchain technology?

The core of the blockchain is that it stores all information in an independent personal computer network, making it a decentralized and distributed structure.
This means that the system is not owned by a controlling company or person, but that everyone can use and run the system.

peopleWhat are the core functions of Human Chain blockchain technology?

What is blockchain technology?

Blockchain has been hyped up like crazy, but you know nothing about it!

Blockchain is a distributed database system participated by different nodes and an open ledger system.

It is composed of a series of data blocks or data packets generated according to cryptographic methods, that is, blocks. Each block of data information is automatically timestamped, thus Calculate a data encryption value, that is, a hash value (hash).

Blockchain technology is essentially a distributed accounting technology. It allows everyone to have an instantly synchronized account book in their hands. Every transaction that occurs in the entire network will have thousands of backups and synchronous records. When perpetrators attempt to tamper with ledger data, they must change the ledger in the hands of the majority of people to achieve their goal.

C. The blockchain technology that blockchain electronic invoices rely on is

Technical principles of blockchain electronic invoices
1. Distribution of private ledgers
Generally, the flow of invoices requires a third-party agency to ensure data security. Since the blockchain has the characteristics of a distributed ledger, it can check and confirm transaction information without relying on a third party, which can reduce tax collection and administration costs.
2. Hash function encryption
The hash function is a simple mathematical function. Simply put, it transforms an input of any length into a fixed-length output through a hash algorithm. The output value is A hash value, usually a combination of letters and numbers. Using hash function encryption to completely record every transaction of a company or individual in the blockchain makes it difficult for someone to tamper with the data, reducing problems such as invoice fraud.
3. Consensus mechanism and smart contracts
The consensus mechanism is a blockchain governance system. It is a set of mechanisms designed by combining economics, game theory and other disciplines to ensure that all nodes in the blockchain are Methods that can maintain the blockchain system are the core to maintaining the safe and stable operation of the blockchain. Smart contracts are programs that digitize contracts in life and automatically execute them when certain conditions are met. Under the influence of the two, blockchain electronic invoices realize the seamless connection of "invoicing as soon as the transaction is completed, and reimbursement as soon as the invoice is issued".
With the continuous development of blockchain technology, it is also undergoing more profound integration with the tax industry. In addition to Beijing, Guangzhou, Shenzhen, Hangzhou and other places have also launched blockchain electronic invoice projects, coveringCovering retail, catering, transportation and other industries, it provides consumers with great convenience. In the future, blockchain electronic invoices will definitely cover our lives more widely and meet people's daily needs.

D. What is the Metaverse and what are its core technologies?

The Metaverse mainly has the following core technologies: one is extended reality technology, including VR and AR, and the other is the ability of digital twins to Mirror the real world into the virtual world, and the third is to use blockchain to build an economic system. The metaverse cannot simply be equated with video games, nor can it be equated with the virtual world. It is creative play, open exploration and connection with reality.

With the explosion of the concept of the Metaverse, virtual digital humans have once again become the focus of public attention. Recently, A-Soul, the leading domestic virtual idol group developed by ByteDance and operated by Lehua Entertainment, caused a chain reaction due to the suspension of its members, making the virtual idol industry and its ecology once again attract the attention of all walks of life. With the fermentation of the idol group A-Soul incident, other virtual people who are one of the investments of the Byte family have also been pushed to the forefront.

It is understood that at the beginning of this year, ByteDance invested in "Li Weike", "Li Weike" and the team behind it: Hangzhou Li Weike Technology Co., Ltd. has also received much attention from the industry and media. focus on. Recently, Hangzhou Li Weike Technology Co., Ltd. launched two new virtual human characters: Lingxia and Xiaoke. The company stated that the new characters, together with Li Weike, will eventually be implemented in AR glasses products.

E. What is the core of the shared vote theory?

"Common vote", one means "community", builds consensus, raises and pools wisdom together, is a truly shared stock, and is consistent with The ideal of communism; the second is "ticket", a ticket for payment, circulation, distribution and rights.

F. Is there any relationship between central bank digital currency and cloud data trade?

There is no direct relationship between central bank digital currency and cloud data trade.

Central Bank Digital Currency (CBDC) refers to a digital currency issued and managed by the central bank, using technologies such as blockchain to realize the digitization of monetary forms. Cloud Data Trading refers to a digital asset trading platform based on financial technologies such as blockchain technology and digital currency. It is an asset trading platform based on blockchain.

Although central bank digital currency and cloud digital currency both involve blockchain technology and digital currency, their nature and application scenarios are quite different. Central bank digital currency is a digital form of legal tender issued and managed by the central bank. It is designed to strengthen the implementation of monetary policy and the effectiveness of financial supervision. Cloud Digital Currency is a digital asset trading platform that provides digital asset trading, savings, Services such as loans are an important direction for the development of the digital economy.

Of course, with the rapid development of digital economy and blockchain technology, central bank digital currency and cloud digital trade may also intersect in some aspects in the future, but there is currently no obvious connection between the two. direct relationship.

G. Blockchain TechnologyWhat are the core technologies of blockchain?

What is the hottest topic on the Internet right now? You don’t need to tell me that it is blockchain technology, but many friends have only heard of it. There is not much in-depth understanding of this technology, so what are the blockchain technologies? Below we will bring you an introduction to the core technology of blockchain for your reference.
What are the core elements of blockchain technology?
Blockchain technology can be a public ledger (visible by anyone) or a permissioned network (visible only by those authorized), which solves supply chain challenges , because it is an immutable record that is shared among network participants and updated in real time.
Blockchain technology----data layer: designing the data structure of the ledger
Core technology 1. Block + chain:
Technically speaking, block is a data structure that records transactions. Reflects the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain.
Each block consists of a block header and a block body. The block body is only responsible for recording all transaction information in the previous period, mainly including the number of transactions and transaction details; the block header encapsulates the current version number, previous A block address, timestamp (recording the time when the block was generated, accurate to seconds), random number (recording the value of decrypting the answer to the math question related to the block), target hash value of the current block, and Merkle number Root value and other information. From a structural point of view, most functions of the blockchain are implemented by the block header.
Core technology 2. Hash function:
The hash function can convert data of any length into a set of fixed-length codes through the Hash algorithm. The principle is based on a cryptographic one-way hash function. This kind of function is easy to verify, but difficult to crack. Usually, the industry uses y=hash(x) to represent it. This hash function implements operations on x to calculate a hash value y.
Commonly used hash algorithms include MD5, SHA-1, SHA-256, SHA-384 and SHA-512, etc. Taking the SHA256 algorithm as an example, inputting any string of data into SHA256 will result in a 256-bit Hash value (hash value). Its characteristics: the same data input will get the same result. As long as the input data changes slightly (for example, a 1 becomes a 0), a completely different result will be obtained, and the result cannot be predicted in advance. Forward calculation (calculating the corresponding Hash value from the data) is very easy. Reverse calculation (cracking) is extremely difficult and is considered impossible under current technological conditions.
Core technology 3. Merkle tree:
Merkle tree is a hash binary tree, which can be used to quickly verify the integrity of large-scale data. In the blockchain network, the Merkle tree is used to summarize all transaction information in a block, and ultimately generates a unified version of all transaction information in the block.The hash value of any transaction information in the block will cause the Merkle tree to change.
Core technology 4. Asymmetric encryption algorithm:
Asymmetric encryption algorithm is a key secret method that requires two keys: public key and private key. The public key and the private key are a pair. If the public key is used to encrypt data, only the corresponding private key can be used to decrypt it, thereby obtaining the corresponding data value; if the private key is used to sign the data, then only the corresponding public key can be used to sign the data. In order to verify the signature, the sender of the verification information is the holder of the private key.
Because encryption and decryption use two different keys, this algorithm is called an asymmetric encryption algorithm, while symmetric encryption uses the same key in the encryption and decryption processes.
Blockchain technology----network layer: realize the decentralization of accounting nodes
Core technology 5. P2P network:
P2P network (peer-to-peer network), also known as point-to-point technology, is no Central server, Internet system that relies on user groups to exchange information. Unlike a centralized network system with a central server, each client in a peer-to-peer network acts as both a node and a server. Domestic Xunlei software uses P2P technology. The P2P network has the characteristics of decentralization and robustness.
Blockchain technology----Consensus layer: allocate the task load of accounting nodes
Core technology 6. Consensus mechanism:
Consensus mechanism is how to reach consensus among all accounting nodes to identify The validity of a record is both a means of identification and a means of preventing tampering. There are currently four main types of consensus mechanisms: PoW, PoS, DPoS and distributed consensus algorithms.
PoW (Proof of Work, proof of work): PoW mechanism, which is like Bitcoin’s mining mechanism, miners package existing transactions that have not been recorded by the network into a block, and then continue to traverse and try to find a random number , so that the hash value of the new block plus the random number meets certain difficulty conditions. Finding a random number that meets the conditions is equivalent to determining the latest block of the blockchain, and is also equivalent to obtaining the current round of accounting rights of the blockchain. Miners broadcast blocks that meet the mining difficulty conditions in the Yuanfu network. After verifying that the block meets the mining difficulty conditions and that the transaction data in the block meets the protocol specifications, other nodes in the entire network will each Blocks are linked to their own version of the blockchain, thereby forming a network-wide consensus on the current network state.
PoS (ProofofStake, Proof of Stake): PoS mechanism requires nodes to provide proof of a certain number of tokens to obtain a distributed consensus mechanism for competing for blockchain accounting rights. If you rely solely on the token balance to determine the bookkeeper, you will inevitably make the rich win, which will lead to the centralization of bookkeeping rights and reduce the fairness of the consensus. Therefore, different PoS mechanisms use different methods to increase the amount of money based on the proof of equity. The randomness of accounting rights avoids centralization. For example, PeerCoin’s PoS mechanism has the mostBitcoin with a longer multi-chain age has a greater chance of obtaining accounting rights. NXT and Blackcoin use a formula to predict the next accounting node. The more tokens you own, the greater the probability of being selected as an accounting node. In the future, Ethereum will also switch from the current PoW mechanism to a PoS mechanism. Judging from the information currently available, Ethereum's PoS mechanism will use nodes to place bets on the next block. The winner of the bet will receive an additional Ethereum currency award. Those who do not win will be deducted Ether coins to reach consensus on the next block.
DPoS (DelegatedProof-Of-Stake, share authorization certificate): DPoS is easy to understand and is similar to the modern corporate board of directors system. The DPoS mechanism adopted by BitShares is that shareholders vote to select a certain number of witnesses. Each witness has two seconds of authority to generate blocks in order. If the witness cannot generate a block within the given time slice, The block generation authority is given to the witness corresponding to the next time slice. Shareholders can replace these witnesses at any time by voting. This design of DPoS makes the generation of blocks faster and more energy-saving.
Distributed Consistency Algorithm: Distributed Consistency Algorithm is based on traditional distributed consistency technology. Among them are Byzantine fault-tolerant algorithms that solve the Byzantine Generals problem, such as PBFT (Byzantine fault-tolerant algorithm). In addition, distributed consensus algorithms (Pasox, Raft) that solve non-Byzantine problems are not explained in this article. This type of algorithm is currently a commonly used consensus mechanism in alliance chain and private chain scenarios.
Taken together, POW is suitable for public chains. If you build a private chain, it is more suitable to use POS because there is no trust problem in verification nodes; and because there are untrustworthy local nodes in the alliance chain, it is more suitable to use DPOS.
Blockchain technology----Incentive layer: Develop a "salary system" for accounting nodes
Core technology 7. Issuance mechanism and incentive mechanism:
Take Bitcoin as an example. Bitcoins are initially rewarded by the system to miners who create new blocks, and this reward is halved approximately every four years. At the beginning, miners were rewarded with 50 Bitcoins for each new block recorded, and this reward is halved approximately every four years. By analogy, by around AD 2140, newly created blocks will no longer receive rewards from the system. By then, the total number of Bitcoins will be approximately 21 million. This is the total number of Bitcoins, so it will not increase indefinitely.
Another source of incentives is transaction fees. When there are no system rewards for newly created blocks, the miners' income will change from system rewards to transaction fees. For example, when you transfer, you can specify 1% of it as a handling fee to be paid to the miner who records the block. If the output value of a transaction is less than the input value, the difference is the transaction fee, which will be added to the incentive for that block. As long as a given amount of electronic currency has entered circulation, the incentive mechanism can gradually be converted to rely entirely on transaction fees, so there is no need to issue new currency.
Blockchain technology----Contract layer: giving the ledger programmable features
Core Technology 8. Smart Contract:
Smart contract is a set of scenario-based programmed rules and logic, which is implemented through decentralized, trustworthy and shared script code deployed on the blockchain. Usually, after the smart contract is signed by all parties, it is attached to the blockchain data in the form of program code, and is recorded in a specific block of the blockchain after being propagated through the P2P network and verified by nodes. Smart contracts encapsulate a number of predefined states and transition rules, scenarios that trigger contract execution, response actions under specific scenarios, etc. The blockchain can monitor the status of smart contracts in real time, and activate and execute the contract by checking external data sources and confirming that specific trigger conditions are met.
