Blockchain information tracking method and system

Abstract

The present invention provides a blockchain information tracking method and system, using an asymmetric encryption algorithm to generate a key pair, using the key pair to encrypt an account, using an electronic signature to sign a file, and obtaining the first encrypted file; using a P2P network For data transmission, through the search of the server, the first node is designated to establish a connection channel with the new node, so that the new node uses the flooding mechanism to broadcast the entire network, and the public key of the key pair is published to the P2P network; the first encrypted file is stored In the designated storage area of ​​the stand-alone machine, the network verifies the transmission request through the private key of the key pair; encrypts the first encrypted file after generating a time stamp to obtain the second encrypted file, and makes the second encrypted file generate a public chain, which includes the file Process information; verify the data read request through the private key of the key pair, read the public chain after the verification is passed, and view the downloaded file. Realize the use of distributed storage for public key information records on the server side to ensure data security performance.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and system for tracking block chain information. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. The application of blockchain technology in information tracking can greatly save the time of information tracking. [0003] Patent document CN107944894A discloses a method for tracking retail goods based on blockchain technology, which is divided into the first step, which defines the initial information of retail goods and adds them to the genesis block in the blockchain system. Define the c...

Problems solved by technology

However, the above-mentioned patent documents have storage defects in the information transmission method. For each information tracking request, all nodes need to participate in the calculation to calculate the best and nearest node position, resulting in a relatively slow overall efficiency.
