Specifically, distributed ledgers are decentralized digital ledger technology used to record transaction data; consensus mechanisms are methods for nodes to reach agreement; encryption technology is used to ensure the security of data transmission and access; smart contract programming is used to define and execute business logic on the blockchain; and node monitoring and maintenance software helps ensure the stable operation of nodes. On some well-known blockchain platforms, such as Ethereum and  Hyperledger Fabric, corresponding development tools and resources are also provided."}]}],"pr":"9be9b91202d8463bbe30ed2ca820492d3062146c40a9ce409909148f373142d8"}
