Penalty","a":"The main components of a blockchain include blocks, chains, distributed databases, decentralization, smart contracts, encryption algorithms, etc. Blocks are the basic building blocks of a blockchain,  used to store data and information. Chains are formed by connecting blocks through specific linking information, creating a data structure arranged in chronological order. Distributed databases enable distributed recording and storage of data information. Decentralization refers to the mutual cooperation of nodes in a blockchain network, allowing data verification and storage without a central server. Smart contracts are automatic programs used to handle transactions on a blockchain. Encryption algorithms ensure the security and privacy of blockchain data."}]}],"pr":"d75d41de22608ba0dec3519ce10682699bb9ae07c1f1df278830f55fcca2bf99"}
