Blockchain contract execution ensures data consistency

1. 1. What is the technology of blockchain?

2. Jinwowo, Chongqing: artificial intelligence has the ability to analyze massive data at high speed. As the basis of artificial intelligence, data must be accurate and safe, and there must be no forged data
if the blockchain technology is used, the authenticity and security of data can be guaranteed
by combining the two, consciousness chain forms a data pool, creates an efficient data exchange center, and finally constructs a three-dimensional and multi-functional artificial intelligence ecosystem.

The term "smart contract" can be traced back to at least 1995 and was proposed by the prolific interdisciplinary legal scholar Nick Szabo. He mentioned the concept of smart contract in several articles published on his website. His definition is as follows:

"a smart contract is a set of promises defined in digital form, including the agreements on which the contract participants can implement these commitments."

Let's explore the meaning of his definition in more detail

commitment

a set of commitments refers to the (often mutual) rights and obligations agreed by contract participants. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods and the buyer promises to pay a reasonable price

digital form

digital form means that contracts have to be written into computer-readable code. This is necessary, because as long as the participants reach an agreement, the rights and obligations of smart contract establishment are executed by a computer or computer network

(1) when will the parties to the smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, the contract is discovered when the parties are committed to the execution of the contract by installing the contract on the contract host platform

(2) the real meaning of "execution" also depends on implementation. Generally speaking, implementation means active implementation through technical means

(3) computer readable code

in addition, the specific "digital form" required by the contract is very dependent on the agreement that the parties agree to use

protocol

protocol is technical implementation, on this basis, the contract commitment is realized, or the contract commitment is recorded. Which agreement to choose depends on many factors, the most important of which is the nature of the assets being traded ring the performance of the contract

again, take the sales contract as an example. Suppose that the participants agree to pay in bitcoin. The chosen protocol will obviously be bitcoin protocol, on which the smart contract will be implemented. Therefore, the "digital form" that the contract must use is bitcoin scripting language. Bitcoin scripting language is a non Turing complete, imperative, stack based programming language, similar to forth

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved" blockchain technology professional "pilot workstation of" smart learning workshop 2020 Xueshuo innovation workstation "launched by the school planning, construction and Development Center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system

4. The distributed architecture and tamper proof features of blockchain technology help to solve the problems of bill authenticity and information opacity. When participants need to check whether the bill has been tampered or transferred, blockchain can provide indisputable proof of consistency
digital currency also makes use of this feature of blockchain. Puyin is a kind of tea standard digital currency developed based on blockchain technology.

5. 1> If you have more wuxingshi, you can make money by natural synthesis of high-grade wuxingshi (the unit price of grade 6 is between 600-700g, which may be different in different areas), consume less energy, and the demand is stable< br />2> If you don't have a lot of Wuxing stones on hand, the new version of mining is OK for the time being. Zhenshan iron mine and Yutong copper mine are in demand for 80-90 forging and punching skills, as well as ingots for advanced equipment forging and enchanting. The price of each ingot is 700-900g. However, a single 90 mining specialization consumes 40 physical strength and proces 2-4 ingots each time, so it consumes a lot of physical strength. Later mining is certainly not as stable as wuxingshi market
it is suggested to find a guild to mine in zhurongshan regularly, but don't forget to leave some physical strength value to reset the .

Through the deep use of cryptography algorithm, specially designed data structure and multi-party consensus algorithm, blockchain uses machine algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records, which has a natural strong correlation with electronic data storage

at present, the electronic contract signed on the advanced electronic contract platform has realized the distributed storage of digital fingerprints of electronic documents through the blockchain technology, which further strengthens the legal effect of the platform electronic contract

7. Laikelib blockchain infrastructure operation team analysis: blockchain technology is a breakthrough in network security, because it can ensure the highest level of data confidentiality, availability and security.

If the electronic contract wants to have legal effect, it needs to lock the identity of the contracting party, keep the documents from being tampered with, and accurately record the time. For the electronic documents, it also needs to consider the security of storage

through the deep use of cryptography algorithm, specially designed data structure and multi-party participation consensus algorithm, machine algorithm is used to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records, which has a natural strong correlation with electronic data storage

First of all, the electronic contract signing records are stored in a shared account book jointly maintained by multiple parties, which can not be tampered with, denied or lost

secondly, the text and elements of the electronic contract are encrypted, including the participants of the electronic contract. Only the participants can decrypt and view the data to protect the privacy of the parties

thirdly, the machine strictly implements the pre-defined rules (smart contract), and no longer relies on a single agreement with a third party. KYC service based on blockchain automatically checks and verifies the validity and identity of certificates, and ensures the authenticity of participants' identities on the basis of privacy

blockchain technology is popular in the market because it can rece intermediate links, rece fraud caused by data consistency, improve business efficiency and speed, rece the risk of counterparties, increase revenue and save costs

9. Blockchain has the characteristics of being unforgivable. It can guarantee the authenticity of the contract. Blockchain technology can also be applied to other fields. The blockchain service platform project initiated by Changsha high tech Zone, which has a SMIC blockchain service platform project, is a blockchain + public service mode, and is recruiting enterprises to join the chain. In the future, relevant enterprise affairs and government affairs can cooperate on the chain. It is also one of the key blockchain projects in Hunan Province.
