The principle
basic concept
- Transaction: one operation, leading to a change in the status of books;
- Block: record transaction and status results occur over a period of time, it is a common understanding of the current state of the books;
- Chain: the blocks are connected in series by one order of occurrence, the entire state change log.
Billing content
- Version Information
- Hash value on a block
- Billing time
- Difficulty value
- Trading Information
Distributed books
- Each node (device) has a copy of the full block chain
- You can verify the correctness of the new transaction by the full block chain
- To synchronize each node by P2P networks
Consensus mechanism Pow (workload proof)
- excitation
- Hash calculation
Technology Architecture
image
- Application layer: a variety of digital wallet, trading sites or various sectors of block-based chain to build a website or App;
- Business layer: the business layer mainly Web3 of operational intelligence contract, of course, there are various unreasonable application of its own business function modules;
- Layer contract: Contract layer is mainly achieved by Solidity of each contract;
- Protocol layer: mainly through consensus mechanisms, P2P networks, cryptography block chain store and related technologies, to achieve the bottom of the block chain;
