  • Publication number: 20230353393
    Abstract: The present disclosure discloses methods, apparatus, and storage medium for processing blockchain-based data. The method includes: creating a first world state corresponding to an initial block; updating the first world state according to transactions in the initial block to obtain an initial update state, and performing processing of constructing a clean state tree on the initial update state based on a world state chain to obtain an updated first world state including a clean present world state tree; writing a first world state root corresponding to the clean present world state tree into the initial block to obtain a to-be-on-chained block, writing the to-be-on-chained block into a blockchain when the to-be-on-chained block is approved by consensus, committing the updated first world state to a latest on-chain world state step by step via the world state chain, and determining the updated first world state as a new consensus root world state.

  • Publication number: 20230334009
    Abstract: A data archiving method includes: finding, in local space when an archiving task for a target block header exists, current state trees of block headers, the current state trees including a current state tree that the target block header points to and a current state tree that a first block header before the target block header points to; reconstructing new state trees according to the found current state trees, node reuse information between the current state trees, and target state data corresponding to a second block header after the target block header; and archiving the current state trees stored in the local space to a target archiving server, and deleting the current state trees in the local space after successful archiving.

  • Publication number: 20230090296
    Abstract: A transaction transmitted by a user node in a blockchain network and transaction verification information corresponding to the to-be-verified transaction are acquired. The transaction verification information includes a state read set, a state write set, an initial transaction execution result, and a block identifier of a target block. A first block header of the target block includes the block identifier. A second block header is determined from a block header chain of a light node in the blockchain network. The state read set and the state write set are checked based on a first state snapshot in the second block header. The transaction service is executed to obtain a target transaction execution result corresponding to the transaction service and to-be-written state data. Legitimacy of the to-be-verified transaction is checked based on the initial transaction execution result, the target transaction execution result, the state write set, and the to-be-written state data.
