What is blockchain CSAT

1. blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past. Now there are many procts and applications based on blockchain technology. Lifechain is a medical and nursing enterprise based on blockchain technology. You can learn about it.

2. 1. Public chain, no official organization and management organization, no central server, participating nodes freely access to the network according to the system rules, not controlled, and work based on consensus mechanism among nodes Subversive: absolutely credible and open) < br > typical case: digital currency represents bitcoin < br > 2. The private chain is built within a group. The operation rules of the system are set according to the requirements of the group, and the modification or read permissions are limited to some extent, while maintaining the authenticity and partial decentralization of the blockchain Typical case: R3 < br > 3. Alliance chain, jointly initiated by several institutions, is between the public chain and the private chain, and has the characteristics of partial decentralization. The read permission on the fast chain in this area may be public or partially public, that is to say, multiple pre selected nodes are designated as bookkeepers internally, and the pre selected nodes compete for bookkeeping permission, Other access nodes can participate in the transaction, but not the accounting process The abilities of the candidates should not be uneven< Br > (relatively credible and open) < br > existing cases: Super ledger < br > example:? In the case of loan diversion, when the user jumps to the other party's website for registration through our link, the docking party can choose to cheat and say that it has not received the user's registration request. However, if we put the user registration behavior into the block, if the docking party wants to receive the user registration behavior, it must pay us at the same time.

3. CVT is the abbreviation of the encrypted digital currency token issued by cybervein. In the future, after the main chain of cybervein goes online, CVT will become the gas (service charge) of on chain transactions, which has practical application. If more people use cybervein, the greater the value of CVT will be.

4. In a narrow sense, blockchain is a kind of data structure which is connected in sequence according to the sequence of data blocks. In a broad sense, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus to update data, and uses password to ensure the security of data transmission and access A new distributed infrastructure and computing paradigm using smart contract programming operation data from self script code group

please adopt it if you are satisfied, thank you

5. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography. In a broad sense, 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.
