Embodiment 1

[0072] Such as figure 1 As shown, the chip research and development transaction data storage method provided by the embodiment of the present invention may include the following steps:

[0073] Step 101: Store the smart contract for each chip research and development transaction target on the blockchain;

[0074] Step 102: For each chip R&D transaction target, obtain the transaction data, smart contract message data and chip R&D data generated during the process of at least two transaction nodes participating in the chip R&D transaction target according to the corresponding smart contract within the preset time period ;

[0075] Step 103: For each acquired chip research and development data, store the chip research and development data and the index hash value used to index the chip research and development data in the distributed off-chain storage system;

[0076] Step 104: Determine at least two consensus nodes for a preset time period;

[0077] Step 105: Use at least two...

Embodiment 2

[0086] On the basis of the chip research and development transaction data storage method provided in Embodiment 1, after storing the chip research and development data in the distributed off-chain storage system and storing the index hash value on the blockchain, the nodes with read permission The chip R&D transaction data can be read according to the index hash value. The specific process is as follows: figure 2 As shown, the following steps may be included:

[0087] Step 201: Receive a read request sent by an access node with read authority for the research and development data of a target chip;

[0088] Step 202: Obtain the target index hash value corresponding to the target chip research and development data from the blockchain according to the received read request;

[0089] Step 203: Send the target index hash value to the access node, so that the access node can read the target chip research and development data from the distributed off-chain storage system according ...

Embodiment 3

[0093] On the basis of the chip R&D transaction data storage method provided in Embodiment 1, the smart contract corresponding to a chip R&D transaction target can be any one or more of a virtual intellectual property transaction contract, a virtual intellectual property authorization contract, and a chip R&D contract , where the virtual intellectual property transaction contract is used to define the rules for buying and selling chip research and development data between two trading nodes, the virtual intellectual property authorization contract is used to define the rules for authorizing the use of chip research and development data between two trading nodes, and the chip research and development The contract is used to define the rules of at least two transaction nodes employed to develop chip research and development data.

[0094] By storing different types of smart contracts on the blockchain, smart contracts can be used to control chip intellectual property transactions,...

Abstract

The invention relates to the technical field of data storage. The invention provides a chip research and development transaction data storage method and system. The method comprises the steps of obtaining transaction data, intelligent contract message data and chip research and development data generated by at least two transaction nodes participating in a chip research and development transactiontarget process according to corresponding intelligent contracts in a preset time period; Storing the obtained research and development data of each chip and the index hash value for indexing into a distributed chain storage system; Determining an accounting node from at least two consensus nodes corresponding to a preset time period by using a rapid consensus algorithm; And storing the obtained transaction data, the intelligent contract message data and the index hash value in the generated new block through the accounting node, and linking the new block to the block chain. The scheme can enable chip research and development transaction data to be traceable and tamper-proof.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and system for storing chip research and development transaction data. Background technique [0002] Chips are also known as microcircuits, microchips, and integrated circuits (ICs), specifically referring to silicon chips containing integrated circuits, which have a small size and are usually an important component of computers and other electronic equipment. part. Chip R&D is a complex process, which generally requires software to realize chip functions, form a comprehensive netlist, circuit diagram design, performance simulation verification, layout layout and wiring, layout-to-circuit diagram verification, process design rule verification, physical verification of the layout, and tape-out verification and other links, so the development of a chip usually requires the cooperation of multiple manufacturers. [0003] At present, in the process of chip research an...
