Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Example one
As shown in fig. 1, a method for storing transaction data developed by a decentralized chip according to an embodiment of the present invention may include the following steps:
step 101: for any transaction node in the transaction node cluster, when a first transaction node broadcasts at least one chip development transaction requirement for a chip development transaction target, step 102 is executed, wherein an intelligent contract for the chip development transaction target is stored in a block chain, and a transaction execution trigger condition for each chip development transaction requirement is recorded in the intelligent contract.
Step 102: executing for each chip development transaction requirement: and according to the transaction execution triggering condition of the current chip research and development transaction requirement, when the chip research and development transaction aiming at the current chip research and development transaction requirement is determined to occur between the first transaction node and the second transaction node, according to the intelligent contract, corresponding transaction operation is executed aiming at the first transaction node and the second transaction node so as to obtain transaction data, intelligent contract message data and chip research and development data aiming at the chip research and development transaction.
Step 103: and storing all chip research and development data acquired within a preset time period by using a distributed downlink storage system.
Step 104: and storing all transaction data and all intelligent contract message data acquired within the preset time period by using the block chain.
It should be noted that the tamper-proofing of transaction records and the traceability of chip development transaction related data are fundamental requirements for implementing a decentralized chip development transaction mode. In this embodiment, the blockchain is the core key for implementing the decentralized organization, development mode and transaction mode of the integrated circuit. In addition, in consideration of practical application requirements and characteristics of chip development and transaction, a blockchain based on an intelligent contract is proposed as a blockchain architecture. Thus, an embodiment proposes to implement a decentralized chip development transaction model based on both blockchains and smart contracts. In one embodiment, the transaction operation between the two parties of the transaction is based on a predetermined intelligent contract.
The block chain technology can establish mutual trust relationship through a distributed network, a cryptology account book with unalterable time sequence and a distributed consensus mechanism, fulfill a transaction contract by utilizing an intelligent contract, and integrate global integrated circuit talents and industrial resources through decentralized endorsements. It can be seen that for the realization of the decentralized chip research and development transaction mode, the blockchain is the core key, and the customizable automatic mandatory intelligent contract is the execution guarantee and benefit guarantee.
In detail, the block chain technology can construct a novel distributed computing architecture for data storage, circulation and processing through effective combination of technologies such as cryptography, point-to-point network communication, consensus algorithm, intelligent contracts and the like, and the purposes of difficult data tampering, difficult counterfeiting, traceability, rechecking and the like are achieved without using a credit endorsement condition of a third-party agency.
In detail, the intelligent contracts are assembly language programmed on a blockchain. Typically one will not write the bytecode itself, but will compile it from a higher level language, e.g. a proprietary language like Javascript in Solidity. These bytecodes may provide guidance to the functionality of the blockchain so that the code can easily interact with it, such as transferring cryptographic currency and recording events. The execution of the code is automatic, either successfully executed or all state changes are undone, even including information that has been sent or received from the currently failed contract to avoid partial execution of the contract, noncompliance with the other party to reverse the transaction, etc.
In the blockchain environment, the code and the state of the intelligent contract are on the blockchain, so that all people can see the intelligent contract, and the intelligent contract does not depend on a specific hardware device, and the code of the intelligent contract can be executed by all nodes participating in consensus. Thus, from a user perspective, a smart contract may be considered an automatically secured account, such as when certain conditions are met, the process releases and transfers funds. From a technical perspective, a particular contract program may be run on a blockchain based on intelligent contracts that are spanned over the blockchain.
In this embodiment, a chip demanding enterprise can rapidly bring forward detailed development and budget demands on a platform. Wherein, aiming at a chip development transaction target, one or more chip development transaction requirements can be provided. The chip requirement enterprise may correspond to a transaction node in the blockchain network, and the transaction node broadcasts the chip development transaction requirements in the blockchain network. In this manner, each of the other trading nodes may receive this broadcast content. In a blockchain network, data sharing may be achieved through the broadcast of messages.
Based on the above, the transaction node may be: the authorization node with the common identification right is any one of a common node which is not related to the block construction process but has the block reading right, and a guest node which is not related to the block construction process, has no block reading right, has the transaction right and can read the transaction information related to the guest node. The authorization node may include a professional node and a professional node.
Therefore, the visitor node, the common node and the authorization node can be used as transaction nodes to conduct transactions with other transaction nodes. Wherein, the visitor node can become a common node after being authorized, the common node can become an authorized node after being authorized, and the authorized node can have the common identity to become a common identity node after being authorized. The system nodes of the platform and the authorized nodes with the consensus right can form a consensus node cluster.
In this embodiment, the transaction between two transaction nodes may be monitored in real time by the consensus node. For example, in step 102, when a transaction occurs between the first transaction node and the second transaction node according to the current chip development transaction requirement, the consensus node may obtain transaction-related data. The acquired data is mainly used for storing the data on the chain and the data under the chain respectively so as to record the transaction related data.
When a transaction occurs between two transaction nodes, the transaction nodes broadcast the transaction information in the blockchain network, so that the consensus node can acquire transaction data, intelligent contract message data and chip research and development data of each chip research and development transaction in real time.
In detail, the transaction data may be data such as transaction time, information of both parties of the transaction, and the data amount is usually not large, and may be stored in the block chain. The intelligent contract message data may be message data generated when the current transaction is matched with the intelligent contract, for example, the time of the current transaction is consistent with the time prearranged in the intelligent contract, and the data amount is usually not large and can be stored in the block chain. The chip development data can include stage products developed, such as design drawings and the like, the data volume is generally large, and the data volume can be stored in a distributed under-chain storage system.
It can be seen that, in this embodiment, the data layer may include two parts, namely an uplink part and a downlink part, where the uplink part may be a distributed block chain ledger, and is a data structure for concatenating blocks into a linked list, and the downlink part may be a distributed storage system.
In detail, the basic technical feature of the blockchain is that transactions occurring within a period of time are organized into blocks, the blocks are linked together cryptographically according to sequence to form a blockchain, the blockchain is copied and shared among the participating nodes of the blockchain network, and the content of the blockchain is maintained collectively by the network formed by the participating nodes according to different consensus mechanisms. Generally, the consensus mechanism on the blockchain can be mainly used to solve the problem of who constructs the blockchain and how to maintain the blockchain uniformity.
In this embodiment, for the block chain, the transaction is the main content constituting the block, the block is the data organization unit of the block chain network, the blocks are connected in series by the linked list, and the hash operation is the connection link.
In this embodiment, for the part on the chain, specifically, the transaction data and the smart contract message data in the latest period of time may be packaged into blocks by the common identification node, and the newly generated blocks are linked to the block chain according to the occurring time sequence. The transaction is similarly packaged into the block and becomes a non-falsifiable transaction, so that the security of the transaction is ensured, namely the transaction is confirmed.
Example two
The second embodiment is basically the same as the first embodiment, and the same parts are not described again, except that: the method may further comprise: storing a target hash value of each chip research and development data acquired within the preset time period by using the distributed type under-link storage system;
the step 104 includes: generating a new block, wherein a block body of the new block comprises each target hash value, all transaction data and all intelligent contract message data acquired within the preset time period, and a block header of the new block comprises a hash value for a last block in the block chain, a hash value for the block body, and a timestamp of a new block generation time; and linking the new block to the block chain according to the sequence of block generation time based on the timestamp.
Each tile may include two parts, a tile header and a tile body. The block main body also comprises target hash values of all chip development data collected in the time period. The target hash value is also present in the distributed storage system under the chain, and is mainly used for address addressing, so that the required chip development data can be quickly inquired from the distributed storage system under the chain based on the block chain.
The hash value of the previous block may be used as the header information of the current block. The header information of the current chunk may also include hash values of those transaction data and smart contract message data that are packaged. The header information includes timestamps that can be used for ordering between blocks. Furthermore, in one possible implementation, the header information further includes version information, information related to a consensus mechanism, and the like. The information related to the consensus mechanism may be, for example, an autonomous ore mining random number, an autonomous ore mining target value, or an ore mining difficulty.
In the second embodiment, the transaction data of the chip research and development transaction and the intelligent contract message data can be stored and managed on the block chain, so that the purpose of traceable and tamper-proof can be achieved, the reliable operation of the chain can be ensured, the monitorability can be enhanced, and the block discharging speed and the stability of the block can be improved.
In this embodiment, for the part under the chain, the chip development data related to the chip development transaction may be stored as the data under the chain in the unified distributed storage system under the chain. In detail, the distributed linked-down storage system may include a cloud storage server, and/or a system node that is always on-line and stably operating.
In detail, for the cloud storage server, a node of the cloud storage server is to be used for storing non-uplink traffic data. The cloud storage server may provide a high throughput, content-addressed block storage model and content-addressed hyperlinks. And storing unstructured data such as resources, videos and documents in the platform through a cloud storage server. After the uploading and downloading operations of the user are verified by the authority of the application server, an operation request can be made to the cloud storage server.
EXAMPLE III
The third embodiment is basically the same as the second embodiment, and the same parts are not described again, except that: the method may further comprise: according to the intelligent contract, when an acquisition request of a transaction node for any chip research and development data of the chip research and development transaction is received, a target hash value of the requested chip research and development data stored on the block chain is fed back to the transaction node, so that the transaction node acquires the chip research and development data corresponding to the target hash value obtained by feedback from the distributed under-chain storage system.
In detail, when the chip research and development data is stored in the down-link storage server, in order to facilitate the query, the down-link storage server also stores the hash value of the chip research and development data correspondingly, and the hash value is used as the addressing address together with the target hash value. Correspondingly, the target hash value is correspondingly stored in the block chain. The file address based on the Hash algorithm can provide the best safety guarantee for distributed data storage.
In detail, when a chip development data needs to be queried, the corresponding transaction node can broadcast the data query request, so that the consensus node can find the target hash value of the chip development data from the block chain according to the intelligent contract to feed back the target hash value to the transaction node. Correspondingly, the transaction node can acquire chip research and development data corresponding to the hash value stored under the link according to the hash value obtained by feedback.
In summary, the present embodiment can store the chip research and development transaction data based on a link-up-link-down combination manner, so as to be suitable for storing the chip research and development transaction data with a larger data volume.

In the fourth embodiment, for any chip research and development transaction requirement, chip research and development enterprises corresponding to other transaction nodes can automatically bid, and the chip research and development enterprise who wins the bid is responsible for the research and development operation of the chip research and development transaction requirement. The transaction node corresponding to the winning bid chip research and development enterprise is the second transaction node. Therefore, the transaction node in the embodiment can be a chip research and development transaction demand party and a chip research and development execution party.

In detail, the transaction execution trigger condition may include an agreement transaction trigger condition and a contact transaction trigger condition. For example, when the transaction operation between the two transaction parties meets the trigger condition for reaching the transaction, the generated transaction data, intelligent contract message data and the like can be written into the block chain, and the transaction operation required to be executed when the transaction is reached, which is preset in the intelligent contract, is executed, such as the transfer of transaction funds and the like. When the transaction operation between the two transaction parties meets the trigger condition for releasing the transaction, the generated transaction data and the transaction data of the intelligent contract can be written into the block chain, and the transaction operation required to be executed when the transaction is released, which is preset in the intelligent contract, is executed, such as compensation of the transferred transaction fund and the like.
As a result, the intelligent contract as a chain code has the advantages of high-efficiency real-time updating, accurate execution, no human intervention, distributed supervision and arbitration, low running cost and the like. The two parties of the transaction are directly connected together based on the intelligent contract without the existence of an intermediary, thereby avoiding the existence of high intermediary cost. Based on the intelligent contract and the block chain, due verification of all transactions and messages can be ensured, the diversity, the intelligence, the safety and the expandability of the transactions are ensured, and the reliability, the manageability and the stability of a research and development transaction platform are enhanced.
The chip development transaction can be a development transaction, a trading transaction and the like, so the intelligent contract in the fifth embodiment can be applied to a multi-level intelligent contract system so as to deal with various complex chip development transactions and finished chip transactions.
EXAMPLE six
As shown in fig. 2, based on the first to fifth embodiments, a sixth embodiment provides another method for developing transaction data storage by using a decentralized chip, so as to develop a contract example, which may include the following steps:
step 201: for any transaction node in the transaction node cluster, when the common node a broadcasts 3 Chip development transaction requirements for SoC (System on Chip), step 202 is executed, wherein a development contract for SoC is stored in the block chain, and a transaction execution trigger condition for each Chip development transaction requirement is recorded in the development contract.
For example, the chip development transaction demander puts 3 chip development transaction requirements, namely, a digital IP (Intellectual Property) requirement, a simulation IP requirement and a radio frequency IP requirement, through a development contract according to the system performance requirement.
In detail, the research and development contract may specify the performance index, interface standard, process parameter and other requirements that each chip research and development transaction requirement finally needs to meet, and the condition, form and payment paid by the enterprise for developing each chip research and development transaction requirement.
Step 202: executing for each chip research and development transaction requirement: the consensus node C receives bidding data broadcast by each of the other trading nodes for the current chip development trading needs.
After the demand is released, all users on the platform, including enterprises and individuals, can carry out demand development work in a bidding mode, and finally, as long as submitted bidding data meet the requirements of contract development, the users have the opportunity to win in final bidding selection.
Step 203: and the consensus node C determines an authorized node B which broadcasts the target bidding data to bid, wherein the research and development contract target bidding data meets the transaction execution triggering condition of the research and development trade requirement of the current chip of the research and development contract.
For example, the delivery form agreed in the development contract may be that, on the premise of meeting the performance index requirement, the earliest submitter wins, and then the developer at the earliest system submission time can bid the bid and will automatically obtain the corresponding reward through the development contract.
For another example, taking the digital IP requirement as an example, the transaction execution triggering conditions of the data IP requirement set in the development contract may include successful bidding triggering conditions, so that the consensus node may screen out each bidding data meeting the successful bidding triggering conditions from the bidding data of all the bidding data IP requirements, and automatically and intelligently sort the picked bidding data based on the preset sorting rule. Thus, the enterprise can select bidding data of winning a bid according to the sequencing result and broadcast the winning bid result in the block chain. And then, the consensus node can execute corresponding transaction operation on the enterprise and the winner according to the transaction execution triggering condition of the data IP requirement. For example, when the final product broadcasted by the transaction node of the winning bidder meets a preset transaction achieving triggering condition, the transaction is determined to be ended, and the corresponding transaction information data is written into the block chain.
Step 204: the consensus node C executes transaction data recording processing based on the block chain when determining that a chip research and development transaction occurs between the common node A and the authorized node B, or executes transaction release processing based on the block chain when determining that a transaction trigger condition is met, so as to acquire transaction data, intelligent contract message data and chip research and development data aiming at the chip research and development transaction.
The consensus node C may be any one of all consensus nodes.
In detail, any transaction operation of both transaction parties can be automatically triggered and executed by a transaction triggering condition of a preset intelligent contract, corresponding transaction data and intelligent contract message data are written into a block chain, and the research and development and transaction of a chip are not required to be completed through traditional centralized companies and organizations.
Step 205: the consensus node C stores all chip research and development data acquired within a preset time period and a target hash value of each chip research and development data acquired within the preset time period by using the distributed cloud storage server.
Assuming that the common node C has the accounting right after all the common nodes are common, a new block is generated by the common node C. In detail, the consensus node C may send the data needing to be stored in the link to the distributed cloud storage server, so that the distributed cloud storage server performs the link distributed storage.
Step 206: and the consensus node C generates a new block, wherein the block body of the new block comprises each target hash value, all transaction data and all intelligent contract message data acquired within a preset time period, and the block header of the new block comprises the hash value of the last block in the block chain, the hash value of the block body and a timestamp of the new block generation time.
Step 207: and linking the new block to the block chain by the consensus node C according to the sequence of the block generation time based on the timestamp.
Step 208: and the consensus node D feeds back a target hash value of the requested chip research and development data stored in the block chain to the common node E when receiving an acquisition request of the common node E for any chip research and development data of the chip research and development transaction according to the research and development contract.
It is assumed that the development contract records that the common node E has access right to chip development data of the chip development transaction, so that any consensus node, for example the consensus node D, can return a target hash value for address addressing through the development contract when receiving a corresponding acquisition request.
Step 209: and the common node E acquires chip research and development data corresponding to the target hash value obtained by feedback from the distributed cloud storage server.
