DISTRIBUTED BLOCKCHAIN DATA STORAGE UNDER ACCOUNT MODEL

摘要

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain data storage. One of the methods includes identifying an account identifier (ID) of a blockchain account involved in the transaction, wherein the transaction is included in a current block to be appended to a blockchain associated with the blockchain network based on performing a consensus algorithm; updating an account state corresponding to the account ID of the blockchain account to an updated account state based on the blockchain transaction after the current block is appended to the blockchain; hashing the updated account state to generate a hash value of the updated account state; identifying the hash value of the account state corresponding to the blockchain account based on the account iD of the blockchain account; and updating, in the current state database, the hash value of the account state to the hash value of the updated account state.
