Events 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. Jinwowo analysis: simple value transmission enables digital assets to circulate freely on the blockchain.

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. 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.

6. In short, a group digs bitcoin on the computer, which is equivalent to a big mine.

7. It's a state transition code
for example, my account a
has 100 yuan
after running contract B,
becomes 80 yuan
the contract changes the status of 100 to 80
the contract itself is also an account, and external time (transaction, event)
can also trigger state transition.
