What are the advantages of smart contract blockchain

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. With the breakthrough of blockchain technology, the smart contract has a chance of rebirth. The smart contract based on blockchain technology can not only give play to the advantages of smart contract in cost efficiency, but also avoid the interference of malicious behavior on the normal execution of the contract. The smart contract is written into the blockchain in digital form, and the characteristics of blockchain technology ensure that the whole process of storage, reading and execution is transparent, traceable and unchangeable; At the same time, the strong security consensus mechanism does not need the intervention of three parties: a set of state machine system is constructed by the consensus algorithm of the blockchain, so that the intelligent contract can run efficiently.

3. 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

4. In a word, the blockchain technology has realized the smart contract. Specifically, you can go to the app of lianpai community to learn about it. The lecturer in the app said that the blockchain related content is very simple, easy to understand and professional

5. It's a state transition code
for example, my account a has 100 yuan. After running contract B, it became 80 yuan. The contract is to change the status of 100 to 80. The contract itself is also an account, and external time (transaction, event) can trigger state transition.

6. Is smart contract used to explain blockchain

7. Code is the law, no one can tamper with, everything is automatically executed< Make complaints about br / > block chain

8. The so-called smart contract is a set of commitments defined in form, which controls the digital assets and includes the rights and obligations agreed by the contract participants, and is automatically executed by the computer system
the relationship between smart contract and blockchain: jinwowo Group believes that it can do this analysis:
blockchain technology is decentralization, which can be used to transform into many different digital assets and create different values through transformation
the area center function of blockchain technology can be used to create, confirm and transfer various types of assets and contracts
the smart contract based on blockchain technology can not only give full play to the advantages of smart contract in cost efficiency, but also avoid the interference of malicious behavior on the normal execution of the contract.

9. Chongqing jinwowo: smart contract has the advantages of transparency and credibility, automatic execution and compulsory performance
the important reason is that for a long time, there is no environment to support trusted code running, so automatic enforcement cannot be realized. For the first time, blockchain has made the concept of smart contract a reality.

10. The characteristics of smart contract in Chongqing jinwowo analysis blockchain technology are as follows:

1. 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 check its code and data at runtime

2. Can't tamper

all data of the blockchain itself can't be tampered, so the smart contract code deployed on the blockchain and the data output 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

3. Permanent operation

the nodes supporting the blockchain network often reach 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.
