Embodiment 1

[0042] Such as figure 1As shown, a decentralized chip research and development transaction data storage method provided in Embodiment 1 may include the following steps:

[0043] Step 101: Obtain the transaction data, smart contract message data, and chip research and development data generated by each chip research and development transaction within a preset period of time.

[0044] Step 102: Utilize at least two consensus nodes to perform at least one hash operation on the block header sequentially, wherein each hash operation obtains a hash value, and the block header is based on all transaction data and all smart contract message data.

[0045] Step 103: Determine the target consensus node as an accounting node, wherein the target consensus node preferentially calculates a hash value that is less than the preset autonomous mining target value.

[0046] Step 104: Through the bookkeeping node, store all chip research and development data generated within the preset time per...

Embodiment 2

[0055] Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: before using at least two consensus nodes to perform at least one hash operation on the block header sequentially, it further includes: from at least two The at least two consensus nodes are selected from system nodes and at least one authorization node, wherein the system node is a node that is always online and operates stably, and the authorization node is a practitioner user node with consensus authority.

[0056] In detail, the system node can be a node in the peer-to-peer network that can always run stably online, and belongs to the node deployed to ensure normal data storage at any time, so the system node usually does not have a corresponding employer or individual practitioner. Correspondingly, the authorized node is a practitioner user node with consensus authority in the peer-to-peer network, that is, the authorized node corresponds to a pract...

Embodiment 3

[0062] Embodiment 3 is basically the same as Embodiment 2, and the similarities will not be repeated. The difference is that: selecting the at least two consensus nodes from at least two system nodes and at least one authorization node includes: selecting from at least two system nodes and at least one authorization node. At least one target authorization node is selected from an authorization node, wherein the probability of any authorization node being selected as the target authorization node is proportional to the participation degree corresponding to the authorization node, and the participation degree is determined by the online time of the authorization node and / or determining by evaluating scores; determining the at least two system nodes and the at least one target authorization node as the at least two consensus nodes.

[0063] It should be noted that the target authorized nodes selected from the authorized nodes are all online, and the offline authorized nodes will n...

Abstract

A method and system for storing decentralized chip research and development transaction data, wherein the method comprises: acquiring transaction data, smart contract message data and chip research and development data, which are generated by each chip research and development transaction within a preset time period (101); using at least two consensus nodes to perform at least one Hash operation on a block header in turn, obtaining one Hash value from each Hash operation, and the block header is obtained according to all the transaction data and all the smart contract message data generated within the preset time period (102); determining the consensus node that preferably calculates a Hash value less than a preset autonomous mining target value as an accounting node (103); storing all the chip research and development data generated within the preset time period into a distributed off-chain storage system through the accounting node, and storing all the transaction data and all the smart contract message data generated within the preset time period into a blockchain (104). Data can be separately stored on the chain and off the chain, which is therefore suitable for storing a large amount of chip research and development transaction data.

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...
