BLOCKCHAIN-BASED METHODS AND APPARATUSES FOR PROCESSING DATA, DEVICES AND READABLE STORAGE MEDIUMS

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.
