Abstract

An embodiment of the present invention provides a method for blockchain data migration, comprising: terminating a transaction corresponding to at least one smart contract in the first blockchain system based on first transaction information, and deriving the first transaction User status data corresponding to the at least one smart contract in a blockchain system; deploy the at least one smart contract in the second blockchain system based on the second transaction information, and report to the second blockchain The system imports the user state data; and based on the third transaction information, starts a transaction corresponding to the at least one smart contract in the second blockchain system. The user state data is user state information corresponding to the at least one smart contract in the first blockchain system when the transaction corresponding to the at least one smart contract in the first blockchain system is terminated . Embodiments of the present invention also provide an apparatus, medium and computing device for blockchain data migration.

Description

technical field [0001] Embodiments of the present invention relate to the field of Internet technologies, and more specifically, embodiments of the present invention relate to a method, device, medium and computing device for blockchain data migration. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the existing blockchain technology, whether it is a public chain or an alliance chain, all transactions fall on each blockchain node. Blockchain nodes usually use the MPT (Merkle Patricia Tree) data structure for data storage. Among them, the MPT data structure is used to store all transactions, all account data and all receipts in the blockchain system. In the MPT data structure, the data access of a storage node requires multiple disk read and write operations, and eac...
