Is there a smart contract for the characteristics of blockchain

1.

blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. In short, in the blockchain system, the transaction data generated by each participant will be packaged into a data block after a period of time. The data blocks are arranged in chronological order to form a chain of data blocks. Each participant has the same data chain and cannot be tampered unilaterally, Any modification of information can only be carried out with the agreement of the agreed proportion of subjects, and only new information can be added, and the old information cannot be deleted or modified, so as to realize the information sharing and consistent decision-making among multiple subjects, and ensure that the identity of each subject and the transaction information between subjects can not be tampered with, open and transparent

the technical commonness of blockchain projects: block, account, smart contract and consensus, which constitute the general model of the current blockchain system

today, I want to tell you what is a real dragon ball for blockchain application landing and enabling traditional commerce and trade

first of all, dragon ball technology will develop the electronic business platform integration asset plan, and the cable asset payment facility will serve the upcoming block chain business application landing wave. In the future, valuable assets can be applied to all aspects like WeChat payment and Alipay, which will bring convenience to people's payment and life, and at the same time, increase sales to businesses. This is the commercial value brought by Longzhu. Based on Singapore, the Longzhu foundation in Singapore will radiate the world and aspire to become the leader of new asset technology and contribute to the circulation of global commodity trade

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 coincidence that I happened to study in the hashton blockchain training institution recently. The characteristics of blockchain are tamper proof, distributed, consensus mechanism and smart contract. In the future, we can help customers solve the problem of business trust through chain reform technology.

5.

According to reports, blockchain has the advantages of decentralization, distrust and tamper proof

compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

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

7. These characteristics make the blockchain technology can be applied to many instries. The SMIC blockchain service platform launched by Changsha high tech Zone also solicits enterprises to go on the chain, which is a blockchain + public service mode.

8. Network search area chain fraud routines, take a look at it. Ali, Internet, Tencent and the state are still studying the regional chain, but it has not yet taken shape. Do you think those small sesame companies can run faster than these giants? Can I fly you? Hope to save you.

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.
