Abstract

The invention discloses a blockchain data archiving method and device. The method includes: a blockchain node receiving a writing request of transaction data; detecting whether the first blockchain satisfies a preset archiving condition; if not, Write the transaction data into the first block chain; if yes, create a second block chain and write the transaction data into the second block chain, wherein the creation of the second block chain The world block points to said first blockchain. Because in the embodiment of the present invention, when the blockchain node detects that the first blockchain meets the preset archiving conditions, it archives the first blockchain and creates a second blockchain for transaction data Write, because the address of the newly created second blockchain is not limited by the address of the first blockchain, the blockchain node can establish the second blockchain in any storage device in the blockchain node for subsequent The writing of the generated transaction data avoids the problem of storage bottleneck and transfer of transaction data.

Description

technical field

[0001] The present invention relates to the field of block chain technology, in particular to a block chain data archiving method and device. Background technique

[0002] The blockchain system is a data network system that uses node consensus algorithms to generate and update transaction data, uses cryptography to ensure the security of data transmission and access, and generates non-tamperable and non-forgeable distributed ledgers. In the blockchain system, the transaction ledger is stored in a block chain structure, and each blockchain node will store the complete transaction data of the blockchain system. As the running time of the blockchain system increases, the block height of the blockchain and the amount of transaction data stored on the blockchain also increase linearly, which will make the transactions used to store the blockchain in the blockchain nodes Data storage devices face storage bottlenecks.

[0003] Because the address of the blockchain...
