Blockchain is too technical

1. First, the characteristics of decentralization
as the name suggests, a blockchain does not need a centralized server, and all information is stored on each node in the chain in a distributed form. Even if a node is damaged or tampered, the operation of the whole blockchain will not be affected, and the data will not be disordered
Second, consensus mechanism
consensus mechanism plays an important role in the trustworthiness of data on blockchain. Due to the decentralized architecture, any two nodes in the chain do not need to trust each other's identity to establish a connection, and there is no need to trust each other for data exchange. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud. When a transaction is completed, all nodes on the blockchain will synchronize this information, so the consensus mechanism is based on the distributed architecture to ensure the data can not be tampered with
Third, smart contract
before we talk about blockchain + smart contract, let's first clarify the meaning of smart contract: a set of commitments defined in digital form, on which contract participants can implement these commitments. Generally speaking, it is a smart contract. In a computer system, when certain conditions are met, the contract can be executed automatically.

2. The following points are the characteristics of the blockchain summarized by jinwowo group:

1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network

2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud

3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<

4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information

5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

3. There is a risk that the hyped currency may become worthless. It should refer to the speculation of some virtual currencies.

4. It seems that it is not within the scope of demolition for the time being

5. In fact, in our lives, we use the money in the digital money Alipay, the money in the bank card, and the risk of choosing a good platform is not great. DCPRO is very suitable.

6. Take laikelib, a project launched by Shanghai Heshu software, a blockchain company, as an example. Through blockchain and big data technology, we can eliminate the defects of traditional network mutual aid mode and establish a new open and transparent network application development platform
the technical characteristics of the blockchain determine that the underlying framework of laikelib blockchain technology has the following characteristics:
first, independent research and development. Anyone can develop their own applications on the chain; Moreover, all capital flows are open and transparent, and can not be forged or tampered with. Every user can exercise the right of supervision; Second, it's easy to be small. The time of block extraction is short. The transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention; Finally, each user's personal sensitive information will be highly encrypted, and no one else can access it.

7. Take the first project of concentric mutual aid launched by the blockchain start-up company Abbott Financial Technology Co., Ltd. as an example, through blockchain and big data technology, we can eliminate the defects of traditional network mutual aid mode and establish a new open and transparent network mutual aid platform
e to the technical characteristics of blockchain, concentric mutual aid has three characteristics:
first of all, all capital flows are open and transparent, which can not be forged or tampered with, and each user can exercise the right of supervision
secondly, the transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention
finally, each user's personal sensitive information will be highly encrypted, and other people can't access it
based on the above three points, the problems existing in the traditional network mutual assistance mode have been solved one by one.

8. Chongqing jinwowo network analysis:
blockchain technology, which is needed by all enterprises, has begun to penetrate into the whole society, and has developed rapidly in the market. All aspects of technology can be seen everywhere, but there are few good technologies, and blockchain technology is just the first choice to meet the needs of the instry.
