Embodiment 1

[0033] Such as figure 1 As shown, Embodiment 1 provides a decentralized chip research and development transaction data storage method, which may include the following steps:

[0034] Step 101: For any trading node in the trading node cluster, when the first trading node broadcasts at least one chip research and development transaction demand for a chip research and development transaction target, execute step 102.

[0035] Step 102: Execute for each of the chip research and development transaction requirements: according to the smart contract for the chip research and development transaction target stored on the block chain, between the first transaction node and the second transaction node are determined, When there is a chip research and development transaction for the current chip research and development transaction demand, the transaction data, smart contract message data and chip research and development data for the chip research and development transaction are obtained...

Embodiment 2

[0053] Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is: the first transaction node is: an authorized node with consensus power, which does not involve the block construction process but has the right to read the block Ordinary nodes, any of the visitor nodes that do not involve the block construction process, do not have block reading rights, have transaction rights and can read transaction information related to themselves;

[0054] The second transaction node is: any one of the authorized node, the normal node and the visitor node;

[0055] The authorized nodes include business entity nodes and business individual nodes.

[0056] In detail, guest nodes, ordinary nodes and authorized nodes can all be used as transaction nodes to conduct transactions with other transaction nodes. Among them, the guest node can become an ordinary node after being authorized, the ordinary node can become an authorized node after b...

Embodiment 3

[0059] Embodiment 3 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the method may further include: performing at least one transaction data and all smart contract message data included in the block body. The double-hash algorithm is combined with two-by-two splicing operations to obtain a Merkle tree root hash value as the hash value for the block body.

[0060] Correspondingly, the hash value of the previous block can also be the root hash value of the Merkle tree of the previous block.

Abstract

The invention relates to a decentralized chip research and development transaction data storage method and a decentralized chip research and development transaction data storage system. The method comprises the following steps of using a transaction node broadcasting chip to research and development the chip research and development transaction demands of the transaction targets; for each chip research and development transaction demand, according to a corresponding intelligent contract on the block chain, when it is determined that a chip research and development transaction occurs between the chip research and development transaction demand and another transaction node, obtaining corresponding transaction data, intelligent contract message data and chip research and development data; storing all chip research and development data and target hash values thereof in a preset time period by using a distributed chain storage system, wherein the block main body comprises each target hash value and all transaction data and smart contract message data in a preset time period, and the block head comprises a hash value of a previous block, a hash value of the block main body and a timestamp; and linking the new block to the block chain based on the timestamp. Due to the fact that data can be stored separately in a chain-up and chain-down mode, the method is suitable for the storing chip research and development transaction data with large data volume.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for storing decentralized chip research and development transaction data. Background technique [0002] Integrated circuits are the cornerstone of the information industry, and the development of the integrated circuit industry requires a solid technical foundation and long-term accumulation. At present, the development of integrated circuits needs to go through links such as hardware code, circuit, simulation, process, layout, tape-out test verification, packaging, etc., and each link needs to be maintained by a professional team. [0003] At present, chip research and development transaction data can be stored based on the traditional Ethereum data layer. Among them, Ethereum is an open source public blockchain platform with smart contract functions. In this way, it is not suitable for storing chip research and development transaction data with a...
