Evidence storage and recovery method for blockchain account balance

Abstract

The invention discloses an evidence storage and recovery method for a blockchain account balance. A third-party supervision mechanism, a mobile terminal, a bank terminal, a block chain client and a pre-stored node device are included. The output end of the third-party supervision mechanism is connected with the input end of the mobile terminal. The mobile terminal is in bidirectional connection with the blockchain client through a wireless network, the blockchain client is in bidirectional connection with the bank terminal through the wireless network, the output end of the bank terminal is connected with the input end of the mobile terminal, and the blockchain client is in bidirectional connection with the pre-stored node device through asymmetric encryption. According to the evidence storage and recovery method for a blockchain account balance, firstly, the system can log in only through personal verification, and a third-party supervision mechanism is added to the accuracy of information to carry out secondary confirmation, so that the accuracy of evidence storage data is improved, the safety effect of the evidence storage data is ensured, and the problem of information loss ordata inaccuracy is avoided.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for depositing and restoring block chain account balances. Background technique [0002] Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains A batch of bitcoin network transaction information is used to verify the validity of the information (anti-counterfeiting) and generate the next block. In a narrow sense, the blockchain is a system that connects data blocks sequentially in chronological order. A chained data structure composed of various methods, and a non-tamperable and unforgeable distributed ledger guaranteed by cryptography. In a broad sense, blockchain technology uses a block-chain data structure to verify and store data. A new distributed infrastructure and computin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for depositing and recovering a block chain account balance, so as to solve the problem in the above-mentioned background technology that the existing account balance is likely to cause data loss during the process of calculating and depositing certificates, and immediately after the data is lost The accuracy of transaction history information cannot be well guaranteed, which affects the accuracy and traceability of transactions, and the information of general account balances is easily intercepted during settlement, so that information is easy to leak, resulting in security in the transaction process falling problem
