example 1

[0196] This method is suitable for scenarios where a large number of blocks can be deleted, and requires the local node to record several sets of parameters, and each set of parameters corresponds to a set of consecutive deleteable blocks. Each set of parameters consists of the following:

[0197] Head pointer: Record the hash value of the parent block header of the first block in a set of consecutive deleteable blocks.

[0198] Tail pointer: Record the hash value of the sub-block header of the last block in a group of consecutive deletable blocks.

[0199] Check value: operate on the hash values ​​of all block headers in a group of consecutive deletable blocks, and save the operation result as a check value. See the example below for the calculation method.

[0200] by Figure 5 Take the block chain shown as an example. The hash value of the block header of block k is recorded as hk. If block i to block j need to be deleted, the node needs to calculate the following parame...

Abstract

The embodiment of the invention discloses a blockchain light-weight processing method, a blockchain node and a storage medium. The method applied in the first blockchain comprises the steps of: generating a reference block based on continuously distributed N blocks to be deleted in a transaction chain, wherein N is a positive integer; deleting the N blocks in the transaction chain; storing the parameter block, wherein the parameter block and the block without being delete in the transaction chain commonly form an optimal chain, wherein the father block of the reference block is the previous block of the deleted N blocks in the transaction chain, and the sub area of the parameter block is the next region of the deleted N blocks in the transaction chain.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a block chain lightweight processing method, a block chain node and a computer storage medium. Background technique [0002] The blockchain technology that has emerged in recent years is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures that it cannot be tampered with and cannot be forged. The core technology of blockchain is to use block chain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, and use cryptography to ensure the security of data transmission and access. [0003] A big problem with the blockchain is that it will contain all historical transactions. As the transaction volume increases, the blocks in the blockchain will also increase, and the data of the entire blockchain will become larger and larger. The demand for...
