Embodiment 1

[0041] Such as figure 1 As shown, a decentralized chip research and development transaction data storage method provided by the embodiment of the present invention may include the following steps:

[0042] 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, perform step 102. A smart contract for the target of the chip research and development transaction, where the smart contract records transaction execution trigger conditions for each of the chip research and development transaction requirements.

[0043] Step 102: Execute for each of the chip research and development transaction requirements: According to the transaction execution trigger conditions of the current chip research and development transaction requirements, between the first transaction node and the second transaction node, there is a transaction for...

Embodiment 2

[0062] Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the method may further include: using the distributed off-chain storage system to store the data acquired within the preset time period. The target hash value of each chip R&D data;

[0063] The step 104 includes: generating a new block, wherein the block body of the new block includes each of the target hash values, and all transaction data and all smart contract messages obtained within the preset time period data, the block header of the new block includes the hash value for the last block in the block chain, the hash value for the block body and the timestamp of the generation time of the new block; based on the Timestamp, linking the new block to the block chain according to the order of block generation time.

[0064] Each block can include two parts, block header and block body. Among them, the transaction data and smart contract message data co...

Embodiment 3

[0070]Embodiment 3 is basically the same as Embodiment 2, and the similarities will not be described again. The difference is that the method may further include: according to the smart contract, after receiving a transaction node to develop any chip for the chip development transaction When requesting R&D data acquisition, feed back the target hash value of the requested chip R&D data stored on the blockchain to the transaction node, so that the transaction node obtains the feedback obtained from the distributed off-chain storage system The chip development data corresponding to the target hash value.

[0071] In detail, when the chip research and development data is stored in the off-chain storage server, for the convenience of query, the corresponding hash value will also be stored in the off-chain storage server, which is the same as the above-mentioned target hash value, and used as an addressing address. Correspondingly, the target hash value will be correspondingly stor...

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: a transaction node broadcasts each chip research and development transaction demand of a chip research and development transaction target; for Research and development transaction requirements of all chips, according to a transaction execution triggering condition of a current chip research and development transaction demand in a smart contract stored on the block chain, when it is determined that a chip research and development transaction for the current chip research and development transaction demand occurs between the intelligent contract node and another transaction node, corresponding transaction operation is executed for the intelligent contract node and the other transaction node according to the intelligent contract, so that corresponding transaction data, intelligent contract message data and chip research and development data are obtained; And all chip research and development data in a preset time period is stored by using a distributed chain storage system, and all transaction data and all intelligent contract message data in the preset time period is stored by using a block chain. Due to the fact that data can be stored separately in a chain-up and chain-down mode, the method is suitable for 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...
