Timestamp, usually a sequence of characters, uniquely identifies the time at a certain moment. Digital time stamping technology is an application of a variant of digital signature technology. The timestamp in the blockchain is that what happened at a certain time will be recorded on the blockchain.

⑷ The development status and prospect of blockchain technology

The development status and prospect of blockchain technology
Blockchain technology originated in 2008 by the pseudonym “Nakamoto”. The groundbreaking paper “Bitcoin: A Peer-to-Peer Electronic Cash System” published on the cryptography mailing group by scholars of Satoshi Nakamoto. In the past two years, the research and application of blockchain technology has shown an explosive growth trend. It is considered to be the fifth subversive innovation of the computing paradigm after mainframes, personal computers, the Internet, and mobile/social networks. It is the evolution of human credit. It is the fourth milestone in history after blood kinship credit, precious metal credit, and central bank banknote credit. Blockchain technology is the prototype of the next generation of cloud computing, which is expected to completely reshape the form of human social activities like the Internet, and realize the transformation from the current information Internet to the value Internet. The technical characteristics of blockchain

Blockchain has the characteristics of decentralization, time series data, collective maintenance, programmability, security and trustworthiness. Decentralization: The processes of verification, bookkeeping, storage, maintenance and transmission of blockchain data are all based on the distributed system structure, and pure mathematical methods are used instead of central institutions to establish trust relationships between distributed nodes, thereby forming a decentralized system. Centralized and trusted distributed system; Time series data: The blockchain uses a chain block structure with timestamps to store data, which adds a time dimension to the data and has strong verifiability and traceability; Collective maintenance: The blockchain system adopts a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks (such as the “mining” process of Bitcoin), and select specific Nodes add new blocks to the blockchain; Programmable: Blockchain technology can provide a flexible script code system that supports users to create advanced smart contracts, currencies or other decentralized applications; Secure and trustworthy: Blockchain technology adopts The principle of asymmetric cryptography encrypts data, and at the same time, it uses the powerful computing power formed by consensus algorithms such as workload proof of each node of the distributed system to resist external attacks and ensure that blockchain data cannot be tampered or forged. safety. Blockchain and Bitcoin Bitcoin is by far the most successful blockchain application scenario. Blockchain technology solves the double payment problem and the Byzantine general problem that the Bitcoin system has to face for a long time in the field of digital cryptocurrencies. Different from the credit endorsement mechanism of traditional central institutions (such as central banks), the Bitcoin blockchain forms software-defined credit, which marks a fundamental change from centralized national credit to decentralized algorithmic credit. In recent years, by virtue of its first-mover advantage, Bitcoin has formed a complete ecosystem and industrial chain covering issuance, circulation and financial derivatives markets. Development Context and Trend of Blockchain
Blockchain technology is a universal underlying technical framework, which can bring profound changes to various fields such as finance, economy, science and technology, and even politics. According to the current development of blockchain technology, blockchain technology will experience the blockchain 1.0 mode with programmable digital encryption system as the main feature, the blockchain 2.0 mode with programmable financial system as the main feature and the The blockchain 3.0 model with programmable society as the main feature. However, the above models are actually developed in parallel rather than evolutionarily, and the digital cryptocurrency system of the blockchain 1.0 model is still far from mature, and is actually farther and more difficult from its vision of global monetary integration. At present, the blockchain field has shown a clear development trend driven by technological and industrial innovation, and related academic research is seriously lagging behind and needs to be followed up urgently. The basic model and key technology of blockchain
Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamping technologies; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates various consensuses of network nodesAlgorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, which are programmable features of the blockchain. The application layer encapsulates various application scenarios and cases of the blockchain. In this model, the timestamp-based chain block structure, the consensus mechanism of distributed nodes, the economic incentives based on consensus computing power, and flexible and programmable smart contracts are the most representative innovations of blockchain technology. Application Scenarios of Blockchain Technology
Blockchain technology can not only be successfully applied in the field of digital cryptocurrency, but also has a wide range of application scenarios in economic, financial and social systems. According to the current status of the application of blockchain technology, this paper generally summarizes the current main applications of blockchain into six scenarios: digital currency, data storage, data authentication, financial transactions, asset management and election voting: Digital currency: Bitcoin As a representative, it is essentially a digital currency generated by a distributed network system, and its issuance process does not depend on a specific centralized institution. Data storage: The characteristics of high redundancy storage, decentralization, high security and privacy protection of blockchain make it especially suitable for storing and protecting important privacy data to avoid the damage caused by the attack of centralized institutions or improper rights management. Massive data loss or breach. Data Attestation: Blockchain data is time-stamped, verified and recorded by consensus nodes, and cannot be tampered with or forged. These characteristics make the blockchain widely used in various data notarization and auditing scenarios. For example, blockchain can permanently and securely store various licenses, registration forms, licenses, certifications, certifications and records issued by government agencies. Financial transactions: Blockchain technology and financial market applications have a very high degree of fit. The blockchain can spontaneously generate credit in a decentralized system, and can establish a financial market without central institutional credit endorsement, thus realizing “financial disintermediation” to a large extent; at the same time, the use of blockchain to automate smart contracts and The characteristics of programming can greatly reduce costs and improve efficiency. Asset management: Blockchain enables the identification, authorization and real-time monitoring of tangible and intangible assets. Intangible asset management has been widely used in intellectual property protection, domain name management, point management and other fields; tangible asset management can be combined with IoT technology to form “digital intelligent assets” to achieve distributed authorization and control based on blockchain. Election voting: The blockchain can realize political elections, corporate shareholder voting and other applications in a low-cost and efficient manner. At the same time, based on voting, it can be widely used in fields such as gambling, prediction markets, and social manufacturing. Existing Issues with Blockchain Technology
Security threats are by far the most important issue facing blockchains. Among them, the blockchain based on the PoW consensus process mainly faces the problem of 51% attack, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the computing power of the entire network. Other issues include the potential threat of emerging computing technologies to break asymmetric encryption mechanisms and privacy protection issues. The efficiency of blockchain is also an important factor restricting its application. The blockchain requires each node in the system to keep a data backup, which is extremely difficult for the growing mass data storage. While lightweight nodes can partially solve this problem, industrial-grade solutions suitable for larger scales remain to be developed. Currently, the Bitcoin blockchain can only process 7 transactions per second, and the transaction confirmation time is generally 10 minutes, which greatly limits the application of the blockchain in high-frequency trading scenarios in most financial systems. The PoW consensus process is highly dependent on the computing power contributed by the blockchain network nodes. These computing powers are mainly used to solve SHA256 hash and random number search, and do not produce any actual social value. Therefore, these computing powers are generally considered to be Resources are “wasted”, and at the same time, a lot of power resources are wasted. How to effectively pool the network computing power of distributed nodes to solve practical problems is an important problem that blockchain technology needs to solve. As a decentralized distributed system, the blockchain network will inevitably have a game relationship of mutual competition and cooperation in the interaction process of each node, such as the block interception attack game of the Bitcoin mining pool. The blockchain consensus process is essentially a crowdsourcing process. How to design an incentive-compatible consensus mechanism so that self-interested nodes in the decentralized system can spontaneously perform the verification and accounting of block data, and improve the non-profitability in the system. The cost of rational behavior to suppress security attacks and threats is an important scientific problem to be solved by blockchain. Smart contracts and blockchain technology
Smart contracts are a set of scenario-response programming rules and logic, and are a decentralized, trusted and shared solution deployed on the blockchain.� program code. Usually, after the smart contract is signed by all parties, it is attached to the blockchain data (such as a bitcoin transaction) 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 (such as reaching a specific time or occurrence of a specific event, etc.), and response actions in specific scenarios. The blockchain can monitor the status of smart contracts in real time, and activate and execute contracts by checking external data sources and confirming that certain trigger conditions are met. Smart contracts are of great significance to blockchain technology. On the one hand, smart contracts are the activators of the blockchain, which endow the static underlying blockchain data with flexible and programmable mechanisms and algorithms, and lay the foundation for the construction of programmable financial systems and social systems in the blockchain 2.0 and 3.0 eras. On the other hand, the automation and programmability of smart contracts make it possible to encapsulate the complex behavior of each node in the distributed blockchain system and become a software agent robot in the virtual world composed of blockchain, which helps Promote the application of blockchain technology in various distributed artificial intelligence systems, so that various decentralized applications (Decentralized application, Dapp), Decentralized Autonomous Organization (Decentralized Autonomous Organization, DAO), Decentralized Autonomous Corporation (DAC) and even Decentralized Autonomous Society (DAS) are possible. The main development trend of blockchain and smart contract technology is the evolution from automation to intelligence. The essential logic of various existing smart contracts and their applications is still based on the “IF-THEN” type of conditional response rules of predefined scenarios, which can meet the current needs of automated transactions and data processing. Future smart contracts should have the functions of “WHAT-IF” deduction based on unknown scenarios, computational experiments and a certain degree of autonomous decision-making, so as to realize the leap from the current “automatic” contract to the real “smart” contract. Blockchain-driven parallel society
In recent years, a parallel society based on CPSS (Cyber-Physical-SocialSystems) has emerged, and its core and essential features are virtual-real interaction and parallel evolution. Blockchain is one of the infrastructures to realize the parallel society of CPSS. Its main contribution is to provide a set of effective decentralized data structures, interaction mechanisms and computing models for distributed social systems and distributed artificial intelligence research. And it has laid a solid data foundation and credit foundation for the realization of a parallel society. As far as the basis of data is concerned, management scientist Edward Deming once said: Everyone except God must speak with data. However, in a centralized social system, data is usually in the hands of “a few people” such as the government and large enterprises, and “speaks” for a few people, and its fairness, authority, and even security may not be guaranteed. Blockchain data is stored in highly redundant distributed nodes and is in the hands of “everyone”, enabling true “data democracy”. As far as the credit basis is concerned, a centralized social system will inevitably have the characteristics of a “Mertonian system” due to its high engineering complexity and social complexity, that is, uncertainty, diversity and complexity, the center in the social system. Institutions and rule-makers may have untrustworthy behaviors due to individual interests; blockchain technology helps to realize software-defined social systems. The basic idea is to eliminate centralized institutions and convert unpredictable behaviors into smart contracts. The form is deployed and solidified in the blockchain data in advance, and cannot be forged and tampered with and executed automatically after the event, so that the “Merton” social system can be transformed into a fully observable, actively controlled, and accurately predictable “Newton” social system to a certain extent. “Social System. ACP (Artificial Societies, Computational Experiments and Parallel Execution) method is the only systematic and complete research framework in the field of parallel society management so far. Innovation. The ACP method can be naturally combined with blockchain technology to achieve blockchain-driven parallel social management. First of all, the mechanisms of blockchain’s P2P networking, distributed consensus collaboration, and contribution-based economic incentives are themselves natural modeling of distributed social systems, in which each node will act as an autonomous and autonomous system in the distributed system. Agent. With the improvement of the blockchain ecosystem, the consensus nodes of the blockchain and increasingly complex and autonomous smart contracts will form DACs and DAOs in specific organizational forms by participating in various forms of Dapps, and finally form DAS, that is, in ACP. artificial society. Second, the programmable nature of smart contracts enables blockchains to perform various�� “WHAT-IF” type of virtual experimental design, scenario deduction and outcome evaluation, through which optimal decisions are obtained and automatically or semi-automatically executed through this computational experimental process. Finally, the intelligent assets formed by the combination of blockchain and the Internet of Things make it possible to connect the real physical world and virtual cyberspace, and realize the collaborative optimization of social management and decision-making through the virtual-real interaction and parallel tuning of real and artificial social systems. It is not difficult to foresee that in the future, when all physical assets in the real physical world are registered as smart assets on the chain, it will be the arrival of a parallel society driven by blockchain.

⑸ Which company has the greatest impact on blockchain, which company should write papers, which company should analyze and write a little

Abstract 2018 is an extraordinary year for blockchain. The sharp rise and fall of digital currencies in 2018 and the vigorous development of various technologies have attracted more and more people’s attention to this field.

⑹ After reading the blockchain three plus one article, talk about your views on them

The entire blockchain industry has developed to this day, and it is impossible to return to the past. The probability of Bitcoin crashing is far less than the probability of Bitcoin hitting $100,000. Recently, a listed company has undergone earth-shaking changes due to the application of a blockchain. Such a magical story will also stimulate more and more giant companies to pay attention to the blockchain, thereby promoting the development of the entire industry. The Chicago Mercantile Exchange will launch a bitcoin futures contract in December, which may be another major turning point, perhaps marking a fundamental change in the rules of the game and market structure for the entire industry. Although we missed the legend of Bitcoin, from the perspective of the entire blockchain industry, incorporating blockchain assets into our asset allocation vision may be just the beginning.

⑻ I want to be a block chain Do you have any recommendations for papers in the direction of research?

You can find sample articles in this area by searching “blockchain” on CNKI.

⑼ Are there any easy-to-understand books or articles about blockchain for recommendation?

Blockchain and blockchain technology have been accepted and used by a wide range of people, but I have always had a limited understanding of blockchain and blockchain technology, and I am even more at a loss about how blockchain works and how it operates. Maybe you have seen a lot of related reports, there are a lot of professional terms and terms, but you are still not very clear. Here, Bit Window will explain it for you in a popular way.
Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
This is usually a summary of the profession we see in the reports, but what is the specific form?
First of all, no matter how big the system or how small the website is, there is usually a database behind it. So who maintains this database? In general, whoever is in charge of operating the network or system will maintain it.
If it is the WeChat database, it must be maintained by the Tencent team, and the Taobao database is maintained by the Ali team. Everyone must think that this method is justified, but blockchain technology is not the case.
Second, blockchain technology is also known as distributed ledger technology. That is, if we think of the database as a ledger: for example, Alipay is a typical ledger, and any data changes are ledger-based. The maintenance of the database can be considered as a very simple accounting method.
The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in bookkeeping. The system will select the fastest and best person to book the account within ten seconds or ten minutes. This person will record the changes in the database and account books during this period. recorded in a block.
We can think of this block as a piece of paper. After the system confirms that the records are correct, it will link the data fingerprints of the past ledger to this piece of paper, and then send this piece of paper to everyone else in the system. . And then over and over again, the system looks for the next person to keep their books fast and well, and everyone else in the system gets a copy of the entire ledger.

Finally, since everyone (computer) has exactly the same ledger, and everyone (computer) has exactly equal rights, there will be nocomputer) loses contact or goes down, causing the entire system to crash.
Since there is an identical ledger, it means that all data is open and transparent, and everyone can see what digital changes are on each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider that the account book with the same number and the largest number is the real account book, and a small number of account books with a different number from others are false books.
In this case, it doesn’t make sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire system has only a few nodes, it may be easy to do, but if it is thousands of hundreds of thousands, and it is distributed anywhere on the Internet, unless one person can control most of the computers in the world, it is not very good. It is possible to tamper with such a large blockchain.
I don’t know if I can understand such a popular explanation?
