Problems solved by technology

But at the same time, with the increase of transaction data, there is more and more information in the blockchain. If existing nodes and new nodes want to participate in consensus bookkeeping, they have to spend a lot of time and space to save copies of all data, resulting in a large number of transactions. waste of resources

Embodiment 1

[0031] This embodiment provides a segmented block chain storage method, such as figure 1 shown, including the following steps:

[0032] S1. Generate a new block, divide the original block chain into block segments including several blocks; in this embodiment, the block segment preferably includes 2016 blocks, and the block in the block segment is used to save the previous block. Hash way to connect.

[0033] S2. Divide the blocks in each block segment into blocks containing the information of the previous block segment and ordinary blocks;

[0034] S3. Each node in the area chain only needs to download the block segment corresponding to the new block and the block containing the information of the previous block segment of all block segments to participate in the mining, consensus and bookkeeping of the blockchain.

[0035] If there is an offline node in the blockchain, when the offline node re-enters the blockchain, it only needs to save the block segment corresponding to t...

Abstract

The invention belongs to the field of block chains, and relates to a segmented block chain storage method and device, and the method comprises the following steps: S1, generating a new block, and dividing an original block chain into block segments comprising a plurality of blocks; S2, dividing the block in each block segment into a block containing the information of the previous block segment and a common block; and S3, enabling each node in the regional chain to be capable of participating in mining, consensus and accounting of the regional chain only by downloading the block segment corresponding to the new block and the block, containing the information of the previous block segment, of all the block segments. According to the method and the device, the threshold that the newly addednode participates in consensus bookkeeping is reduced, and the interrupt node can quickly synchronize the block information, so that the newly added node and the interrupt node can participate in block chain consensus bookkeeping through relatively short storage time and relatively small storage space.

Description

technical field [0001] The invention relates to a segmented block chain storage method and storage device, belonging to the technical field of block chains. Background technique [0002] Blockchain technology originated from Bitcoin. It is essentially a technical solution for collectively maintaining a reliable database in a distributed and high-trust manner. Its core technologies include distributed ledger technology, asymmetric encryption algorithms, and smart contracts. Features such as distributed, open and transparent, traceability and high trust. [0003] In the existing blockchain consensus bookkeeping mechanism, whether it is a public chain or an alliance chain, nodes must save the information on all existing blockchains in order to participate in consensus bookkeeping, which is the essential requirement of distributed ledgers. It is also the most powerful guarantee to solve tamper-proof. But at the same time, with the increase of transaction data, there is more an...
