Problems solved by technology

Blockchain technology has the characteristics of decentralization, openness and transparency. As a node device of the blockchain, each computing device can participate in database records, and data synchronization between computing devices can be quickly performed; each node device of the blockchain It is usually necessary to deal with the highly concurrent consensus, verification, and read and write operations of the blockchain system. With the increase of "accounted" blocks, the incremental block data storage will gradually affect the response speed of the memory, which in turn will affect the high-speed response of node devices. Concurrent consensus, verification and response efficiency of read and write operations

Embodiment Construction

[0045] The "block chain" described in the embodiments provided in this manual can specifically refer to a P2P network system with a distributed data storage structure achieved by each node device through a consensus mechanism. The data in the block chain is distributed in time Within the connected "blocks (blocks)", the latter block contains the data summary of the previous block, and according to the specific consensus mechanism (such as POW, POS, DPOS or PBFT, etc.), all or The data of some nodes is fully backed up. Each node device of the blockchain (especially the full node device) usually has to deal with the highly concurrent consensus, verification, and read and write operations of the blockchain system. With the increase of "accounted" blocks, the incremental block data storage will increase. Gradually affect the response speed of the memory, and then affect the response efficiency of node devices for high-concurrency consensus, verification, and read and write operati...

Abstract

One or more embodiments shown in this specification provide a multi-level storage method for blockchain data, where the block data of the blockchain is stored in a multi-level storage system connected to the blockchain; The multi-level storage system includes a first-level storage system for storing the latest block data of the blockchain, and at least one lower-level storage for archiving the block data stored in the first-level storage system system; the method includes: receiving the latest block data of the block chain, and storing the latest block data in the first-level storage system in the multi-level storage system; determining whether the trigger for the A block data migration event of the first-level storage system; if yes, at least part of the block data stored in the first-level storage system is migrated to the lower-level storage system.

Description

technical field [0001] This description relates to the field of network communication technology, and in particular to a method and device for multi-level storage of blockchain data. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Blockchain technology has the characteristics of decentralization, openness and transparency. As a node device of the blockchain, each computing device can participate in database records, and data synchronization between computing devices can be quickly performed; each node device of the blockchain It is usually necessary to deal with the highly concurrent consensus, verification, and read and write operations of the blockchain system. With the increase of "accounted" blocks, the incremental block data storage will gradually affect the response spee...
