If the consensus is the foundation of the blockchain, then the consensus mechanism is the soul of the blockchain.

The first group is data citing the hash of the parent block; the second group is metadata, namely difficulty, timestamp, and Nonce; the third group is the Merkle root of the metadata.

According to the application scenarios and transaction conditions of the data chain itself, the project selects the appropriate consensus mechanism to ensure that each distributed node obtains the data consistency through the algorithm.Three groups of block metadata composition.

and can dynamically apply to different application scenarios of the public chain and the private chain.

However, because Pow has obvious defects such as slow transaction speed, the consensus mechanism of the subsequent data chain in the platform is designed as modular, which can be configured by controlling the chain parameters,

The identity of the subblock changes, and the identity of the sun block also changes, and so on.When a block has many descendants,the block will not change again.

Each block can have only have one parent block and can have multiple subblocks.When the identity of the parent block changes, the identity of the child block also changes

For each block header, a hash is generated by which the corresponding blocks in the blockchain are identified.

It is stored as a flat file or in a simple database.Each block points to the previous block. The data structure is divided into three parts: the block header, the transaction list, and the parent block.

Blockchain is a data structure orderly linked from back and forward by blocks containing transaction information.

The advantage of this structure is that even if some of the nodes fail, it does not affect communication across the entire network。

and eventually the global computer connection becomes a dense network, and the information from one node can eventually spread to all the nodes around the world.

No longer need a central server, each connected computer is an independent individual, connected to thousands of other computers by protocol,

Through a distributed structure, decentralization is achieved, using the P2P network model.

The decentralization effectively avoids data tampering caused by a single node attack.Greatly improves the security of the database.

Distributed storage: After distributed transmission, all data is stored in computers at each node and can be updated in real time.

The message is sent directly to all other nodes of the whole network by a single node through the P2P network layer protocol.

Distributed communication: The nodes of the whole network are connected peer-to-point through the underlying network protocol, without a single centralized server.
