Abstract:
The present disclosure provides a method for hierarchically pruning data in a blockchain transaction, which comprises: acquiring a transaction data set; performing N rounds of pruning on the transaction data set based on a data pruning model to obtain a target data set; and performing processing on the target data set to obtain a target value, wherein the target value is configured as the transaction identification number used when the target data set is on-chain. Based on the customized data pruning model, part of the data in the transaction (e.g., Unlocking-Scripts and Locking-Scripts) can be easily pruned in the process of network transmission, internal storage, or construction of a new transaction (especially the Unlocking-Scripts therein) without affecting the process of verifying the data of other parts of the transaction data, which significantly improves the efficiency of UTXO-based blockchains.
