It is composed of several key components:\n\n1. Blocks: The fundamental unit of blockchain, each block contains a set of transactions that have been verified and encrypted. Blocks are linked to each other in a linear chain, with each block containing the hash of the previous block, forming a continuous chain of blocks.\n\n2. Mining: The process of verifying and adding new transactions to the blockchain. Miners use computational power to solve complex puzzles associated with the transactions, which ensures the security and integrity of the blockchain.\n\n3. Consensus Mechanism: A protocol that ensures all participants in the network agree on the validity of transactions and create new blocks. Popular consensus mechanisms include Proof of Work (PoW) and Proof of Stake (PoS), which incentivize participants to maintain the security and integrity of the network.","a":"The core architecture of  blockchain is divided into five layers, including data layer, network layer, consensus layer, incentive layer, and application layer. The data layer is responsible for storing and managing transaction data on the blockchain, including block headers and block bodies. The network layer is responsible for implementing information exchange between nodes in the blockchain network, adopting a peer-to-peer (P2P) communication mode. The consensus layer determines whether new blocks are added to the main chain, and all nodes on the network need to reach consensus according to unified rules. The incentive layer is responsible for encouraging participants to maintain the security and stability of the blockchain network, stimulating node participation through reward mechanisms. The application layer demonstrates the practical application of blockchain technology in real-world scenarios."}]}],"pr":"1cc0c49fc7486f8a0f67c8d0a1c63daa911d6ef024be9643bc424dc00078a4fa"}
