Problems solved by technology

[0003] At present, in the process of chip research and development and chip trading, there are trading behaviors between manufacturers that cooperate with each other, and the rules for trading between the two parties are constrained by offline contracts. Data cannot be securely stored for use as evidence, resulting in less secure chip R&D transactions

Embodiment 1

[0083] Such as figure 1 As shown, the smart contract-based chip research and development transaction data storage method provided by the embodiment of the present invention may include the following steps:

[0084] Step 101: Store the smart contract for a chip research and development transaction target on the block chain;

[0085] Step 102: Obtain the transaction data and smart contract message data generated during the process of at least two transaction nodes participating in the chip research and development transaction target according to the smart contract within a preset period of time;

[0086] Step 103: Determine at least two consensus nodes for a preset time period;

[0087] Step 104: Utilize at least two consensus nodes to perform at least one hash operation on the block header obtained according to the transaction data and the smart contract message data sequentially, wherein each hash operation obtains a hash value;

[0088] Step 105: Determine a consensus node ...

Embodiment 2

[0095] On the basis of the smart contract-based chip research and development transaction data storage method provided in Embodiment 1, when the chip research and development transaction target is the chip physical transaction business, the smart contract defines the transaction figure 2 The process method shown is for physical chip buying and selling, which specifically includes the following steps:

[0096] Step 201: Instruct the buyer's transaction node to input the order information;

[0097] Step 202: Determine whether the buyer's transaction node pays the fee corresponding to the order information, if yes, execute step 203, otherwise execute step 201;

[0098] Step 203: Determine whether the seller's transaction node confirms the payment, if yes, execute step 204, otherwise execute step 202;

[0099] Step 204: Instruct the seller's transaction node to deliver the chip in kind;

[0100] Step 205: Determine whether the buyer's transaction node confirms receipt, if yes, ...

Embodiment 3

[0103] On the basis of the smart contract-based chip R&D transaction data storage method provided in Embodiment 1, when the chip R&D transaction target is chip intellectual property trading business, the smart contract defines the transaction image 3 The process method shown in the chip intellectual property transaction, specifically includes the following steps:

[0104] Step 301: Instruct the buyer's transaction node to preview the content of the chip intellectual property sold by the seller;

[0105] Step 302: Determine whether the buyer's transaction node pays the fee corresponding to the intellectual property rights of the chip, if yes, execute step 303, otherwise execute step 301;

[0106] Step 303: Determine whether the seller's transaction node confirms the payment, if yes, execute step 304, otherwise execute step 302;

[0107] Step 304: Instruct the seller's transaction node to download the content of the chip knowledge product, and determine the end of the transact...

Abstract

In the technical field of data storage, provided are a smart contract-based chip research and development transaction data storage method and system. The method comprises: storing a smart contract for a chip research and development transaction target on a block chain (101); obtaining transaction data and smart contract message data generated by at least two transaction nodes in the process of participating in the chip research and development transaction target according to the smart contract in a preset time period (102); determining at least two consensus nodes for the preset time period (103); sequentially circularly performing at least one hash operation on the corresponding block head by using the at least two consensus nodes (104); determining the target consensus node as an accounting node, wherein a target consensus node preferentially calculates a hash value which is smaller than an independent mining target value (105); and storing the transaction data and the smart contract message data in the generated new block by means of the accounting node, and linking the new block to the block chain (106). According to the method and system, the safety of chip research and development and chip transaction can be improved.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a method and system for storing chip research and development transaction data based on smart contracts. 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, i...
