Blockchain smart contract technology programmer

1. At present, blockchain is still in its early stage, and then the early (since 2013) research on blockchain contracts are basically multimillionaires, so now basically there is a price without market, and the price rises naturally. By the way, blockchain is the technology behind bitcoin, and contracts are the first and most successful projects of TaiFang, and their prices have increased by at least several thousand times

2. 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.

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. 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.

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

6. The transaction type is nuccerh,
please ask the customer service of the bank for details
run, brother,
good luck.

7. 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.

8. Jinwowo network analysis: e to the immutability of the data in the trust base of the blockchain, the traditional applications are very different. Once they are published on the blockchain, they cannot be modified (they cannot be directly modified and then re published on the original contract).
