Abstract
A method of storing blockchain state data, including: after execution of a transaction in a target block is completed, based on a latest account state of a target account related to the transaction in the target block after update, generating updated data nodes corresponding to the current Merkle state tree of the target block and, based on generated historical data nodes and data nodes other than the reused data nodes corresponding to the target account on the historical Merkle state tree of the previous block of the target block, creating the historical Merkle state tree for the target block.
