DECENTRALIZED CHIP RESEARCH AND DEVELOPMENT TRANSACTION DATA STORAGE METHOD AND SYSTEM

摘要

A decentralized chip research and development transaction data storage method and system. The method comprises: a transaction node broadcasts chip research and development transaction requirements of a chip research and development transaction target; for the chip research and development transaction requirements, according to a corresponding smart contract on a block chain, when it is determined that a chip research and development transaction occurs between the transaction node and the other transaction node, obtain corresponding transaction data, smart contract message data, and chip research and development data; store all chip research and development data and target hash values thereof in a preset time period by using a distributed off-chain storage system; generate a new block, the block body comprising the target hash values and all the transaction data and smart contract message data in the preset time period, and the block head comprising a hash value of a previous block, a hash value and a timestamp of the block body; and link the new block to the block chain on the basis of the timestamp. Due to the fact that data can be stored separately in an on-chain and off-chain manner, the method is suitable for storing a large data volume of chip research and development transaction data.
