The role of blockchain smart contract

1. Smart contract can be simply understood as a piece of code written on the blockchain, which is event driven, has dynamic state, obtains multi-party recognition, and can automatically process the information on the chain according to the preset conditions. Once an event triggers the terms in the contract, the code will be executed automatically. The biggest advantage of smart contract is to use program algorithm to replace human arbitration and contract execution
smart contract is a contract that uses computer language instead of legal language to record terms. Once it is written, it can be trusted by users. The terms of the contract cannot be changed, so the contract cannot be changed. If the procere meets the conditions, it will be carried out, and there is no human interference to ensure absolute fairness
three technical features of smart contract
● data transparency
all data on the blockchain are open and transparent, so the data processing of smart contract is also open and transparent, and any party can view its code and data at runtime
● can't tamper
all data of the blockchain itself can't be tampered, so the code of the smart contract deployed on the blockchain and the data generated by the operation can't be tampered, and the node running the smart contract doesn't have to worry about malicious modification of the code and data by other nodes
● permanent operation
the number of nodes supporting the blockchain network often reaches hundreds or even thousands. The failure of some nodes will not lead to the stop of the smart contract, and its reliability is close to permanent operation in theory, which ensures that the smart contract can be as effective as the paper contract at all times.

2. Chongqing jinwowo analyzes the role of smart contract in blockchain technology as follows:
three characteristics of smart contract in blockchain can be summed up:
1) decentralization. It doesn't rely on the centralized server and runs automatically through the network nodes
2) good trust mechanism. The crisis of trust is greatly reced, and it is not necessary to consider whether the participation is trustworthy
3) high degree of autonomy. Once the condition is triggered, the contract will be executed automatically without interference

3. Chongqing jinwowo analyzes the potential benefits of smart contract in blockchain technology as follows: the potential benefits of smart contract include recing the cost of signing contract, execution and supervision.
4. Chongqing jinwowo network: one of the most promising applications of blockchain technology is smart contract. It can automate business transactions and agreements.
5. Smart contract makes blockchain more scalable and simpler to implement, which makes Ethereum the largest blockchain development platform at present. For convenience of understanding, my definition of smart contract is: smart contract is the executable code in the blockchain environment.
6. The role of smart contract in Chongqing jinwowo analysis blockchain technology is as follows:
smart contract is jointly formulated by multiple users in the blockchain and can be used for any transaction between users. In the agreement, the rights and obligations of each party are specified, and proceres are compiled to specify the conditions for the contract to trigger automatic execution
after uploading to the blockchain, the smart contract can directly control the public welfare project through the code contract, and use the donation or execute the project according to the conditions set by the program, which not only ensures the special use of the donation, but also improves the authenticity and credibility of the project, makes the project execution traceable, and improves the credibility of the charity.

7. Shanghai Heshu Software Co., Ltd. is a professional blockchain technology service provider in China. The smart contract seems to be a script that can be executed accurately. It can also be realized with traditional technology. Why must we use blockchain technology? Personal understanding of blockchain has two characteristics: 1. Data can not be modified or deleted, but can only be viewed and added; 2. Decentralization.
8. Code is the law, no one can tamper with, everything is automatically executed< Make complaints about br / > block chain
9. Take the Feiluo supply chain of fun chain technology as an example. It brings together suppliers (financing demanders), core enterprises, funders, third-party organizations and other participants, covering accounts receivable, credit insurance, asset securitization, digital warehouse receipt, logistics supply chain, green energy and other scene services. It digitizes accounts receivable, digital warehouse receipt and other assets through credit insurance It can build a bridge for the high-quality asset side and the capital side to solve the financing problems of small and medium-sized enterprises.
