A. In what form is the recorded data stored in the blockchain?

Encrypted code. A new block is generated every few minutes, which stores different information composed of different passwords (double keys).

B. About storing information on the block

How to store information on the blockchain: call the API provided by the blockchain platform

General The blockchain platform will provide corresponding interfaces, such as RPC, JSON-RPC, HTTP, etc. Of course, different platforms have different degrees of friendliness

Some companies that specialize in APIs, such as BlockCypher, can provide friendly calls. Interface, it is not very convenient to write answers on mobile phones, just search for it

As for the stored content, I would like to add that on the file hash record chain, in addition to conventional cloud storage, file entities are also based on blockchain. Storage solutions, such as ipfs, storej, etc.

C. In what form is the data in the blockchain stored?

Blockchain is a distributed data storage, but different chains The specific storage forms are different. Distributed storage technology does not store complete data on each computer, but cuts the data and stores it in different computers. It's like storing 100 eggs, not in the same basket, but in different places, the total sum

D. Where is the data in the blockchain stored

< p>Blockchain data all exists in the terminal or in the server. Because we are talking about blockchain, its user terminal can also be a server, and the server can also be a user terminal, so it is all stored on these devices.

E. How to store blockchain transaction information

Blockchain is a large distributed ledger. If detailed data is to be stored on the longest chain, it must be stored on the blockchain. Xilai verifies data. Only data verified by most nodes can be saved on the longest chain. The latest data can be synchronized between nodes, while achieving distributed storage of data, which is not easy to tamper with. Each transaction corresponds to a timestamp, and the status of each transaction can be queried based on the timestamp, which is traceability.
