Problems solved by technology

[0004] As the running time of the blockchain increases, the storage capacity of the blockchain will increase linearly, and the growth rate of this data will even exceed the growth rate of the storage medium capacity. Therefore, blockchain data storage will become a restricted area Important factors in the development of blockchain technology

Embodiment Construction

[0022] The purpose and effect of the present invention will become more obvious by describing the present invention in detail according to the accompanying drawings and specific embodiments.

[0023] Such as figure 1 Described, a kind of block chain data archiving method comprises the following steps:

[0024] (1) Initiate a snapshot request: the system administrator initiates a data snapshot request to the blockchain node, which includes the block height for data snapshot production, and at the same time, the blockchain node returns a random string with a length of 32 as the label of the snapshot;

[0025] (2) Check the legitimacy of the data snapshot request:

[0026] First check the identity of the request initiator through the CA certificate: if the initiator does not have the authority to make snapshots, the request will be directly regarded as an illegal request;

[0027] Secondly, check the correctness of the request content: if the request is an instant trigger requ...

Abstract

The invention discloses a block chain data filing method. The block chain data filing method is divided into two steps of: data snapshot: initiating a snapshot production request to a block chain node by a system manager, carrying out backup on locally maintained account book data by the block chain node after receiving the request, carrying out full-dose hash calculation on the account book data and storing the calculation result as metadata; and data dump: carrying out data dump by the system manager on the basis of a snapshot point after the data snapshot, and carrying out dump on block data, block heights of which are smaller than a block height of the snapshot point, and related transaction data, receipt data, account book modification log data and illegal transaction record data, so as to complete data filing.

Description

technical field [0001] The invention relates to block chain technology, block chain type storage technology, a decentralized block chain CA certificate system, and in particular to a block chain data archiving method. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Completed, the consensus algorithm guarantees its consistency. A public ledger is maintained on the blockchain. The public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. [0003] The blockchain-style blockchain data structure is an important data structure in the blockchain ledger, storing core transaction information. The blockchain is a data structure that is sequentially linked from the back to...
