A method and system for atomic, consistent and accountable cross-chain rewriting are provided. The method is applicable for a blockchain network comprising a set of correlative blockchains. The method includes: in response to a user redaction proposal for any of the correlative blockchains, generating a set of correlative redaction proposals that involve all related transactions depending on a target transaction to be redacted by the user redaction proposal, based on a transaction dependency graph representing a dependency relationship of transactions, wherein at least one of the transactions in the transactions is to be redacted by the user redaction proposal; validating the user redaction proposal and the correlative redaction proposals, according to a predefined cross-chain redaction policy; calling the correlative blockchains for executing the validated redaction proposals; and updating the transaction dependency graph in response to execution of the validated redaction proposals.
