Abstract

The invention provides a transaction evidence storage method based on a block chain. The method is applied to a first decentralized application terminal. The method comprises the following steps of responding to the transaction between the first decentralized application terminal and the second decentralized application terminal, and obtaining and storing transaction data corresponding to the transaction, and sending the transaction data to the block chain in response to the connection of the first decentralized application to the block chain, so that the block chain stores the transaction data. The invention further provides a transaction evidence storage method based on the block chain, the method is applied to the block chain, and the method comprises the following steps: receiving transaction data from a first decentralized application end, storing the transaction data, and sending evidence storage information about the transaction data to the first decentralized application end.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to a block chain-based transaction certificate storage method, device, electronic equipment, and computer-readable medium. Background technique [0002] Blockchain is a distributed ledger technology with the characteristics of decentralization, non-tampering, and traceability. Current public chain products, such as Bitcoin or Ethereum, use block storage technology and encrypted signature technology to ensure that the decentralized application (DApp) based on the public chain cannot double-spend its own digital assets . [0003] However, in the process of implementing the concept of the present invention, the inventor found that there are at least the following problems in related technologies: when using DApps based on alliance chain technology, digital assets issued by alliance chains will be transferred between DApp terminals that may be disconnected from the ...
