Problems solved by technology

The large size of the digital certificate blockchain has been emphasized as a scalability problem. The heavy storage load will increase the cost of the full node, reduce the number of full nodes, and eventually lead to the blockchain being controlled by fewer full nodes. The idea of ​​decentralization contradicts

Embodiment Construction

[0044]The present disclosure provides a digital voucher blockchain compression method based on reducing transaction input. By replacing the hash pointer in the transaction input with an index pointer, the transaction size in the digital voucher blockchain is compressed, that is, using the block height and transaction The index pointer composed of the index replaces the hash pointer in the transaction input. When a new blank node joins the network, the full node applies the compression algorithm to compress the blockchain data and then transmits it, which can reduce the amount of data transmission, and the blank node decompresses the data after receiving the data to obtain the complete blockchain data. Full nodes can also apply this method to reduce the storage space required for local blockchain data, and complete verification of new transactions and blocks based on local information.

Abstract

The invention provides a digital certificate blockchain compression method based on reduction of transaction input, and the method comprises the steps: carrying out the compression of all-node blockchain data, replacing a hash pointer of the transaction input through an index pointer of the transaction input, compressing the transaction size in a blockchain, and obtaining compressed data. According to the method, the index pointer is adopted to replace a hash pointer in transaction input, and the transaction size is compressed, so that the data transmission amount can be reduced during block transmission; meanwhile, for all nodes in the digital certificate block chain, the method can be applied to reduce the storage space required by local blockchain data.

Description

technical field [0001] The present disclosure relates to the technical field of block chains, in particular to a method for compressing digital credential block chains based on reducing transaction input. Background technique [0002] Blockchain technology has the advantages of decentralization, collective maintenance, non-tamperable information, and no need for trust in data storage. Digital certificate technology uses blockchain technology to achieve distributed consensus and prevent double payment. The blockchain is maintained by a group of nodes with consensus protocols (proof of work, proof of equity and proof of equity authorization), and each full node retains the entire block A local copy of the chain, so each node can access historical information, complete search transactions and calculate balances. However, as the amount of data contained in the blockchain gradually increases, its required storage space continues to increase. For example, a complete digital cred...
