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: acquiring transaction data, intelligent contract message data and chip research and development data generated by conducting research and development transactions of each chip in a preset time period.
Step 102: and sequentially and circularly carrying out at least one hash operation on the block head by utilizing at least two common identification nodes, wherein each hash operation obtains a hash value, and the block head is obtained according to all transaction data and all intelligent contract message data generated in the preset time period.
Step 103: and determining the target consensus node as an accounting node, wherein the target consensus node preferentially calculates a hash value smaller than a preset autonomous mining target value.
Step 104: and storing all chip development data generated in the preset time period into a distributed under-chain storage system through the accounting node, and storing all transaction data and all intelligent contract message data generated in the preset time period into a 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. The blockchain technology can establish the trust relationship between two transaction parties through a distributed network, a cryptology book with timing sequence being not tampered and a distributed consensus mechanism.
In the embodiment, the consensus nodes sequentially and circularly perform the hash operation on the corresponding block headers, and the consensus node which preferentially calculates the hash value smaller than the autonomous mining target value is determined as the bookkeeping node, so that the time required for electing the bookkeeping node can be shortened, the rapid consensus is realized, and the consensus efficiency is improved. In addition, the probability that the hash value smaller than the autonomous mining target value is calculated by each consensus node is the same, so that the fairness among the consensus nodes in the consensus process is ensured, and the reliability of the consensus process can be ensured.
In detail, 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.
The transaction data can be data such as transaction time, information of both transaction parties and the like, and the data volume is usually not large and can be stored in a 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.
The transaction data of chip research and development transactions and the intelligent contract message data are stored and managed on the block chain, so that the aim of traceability and tamper resistance is fulfilled, the reliable operation of the chain can be ensured, the monitorability is enhanced, and the block discharging speed and the stability of the block are improved. Therefore, the embodiment can construct a novel distributed computing architecture for data storage, circulation and processing based on the block chain technology, and achieve the purposes of difficult data tampering, difficult counterfeiting, traceability, rechecking and the like without using the credit endorsement of a third-party agency.
Example two
The second embodiment is basically the same as the first embodiment, and the same parts are not described again, except that: before the performing at least one hash operation on the block header sequentially and circularly by using the at least two common nodes, the method further includes: the method comprises the steps that at least two consensus nodes are selected from at least two system nodes and at least one authorization node, wherein the system nodes are always online and stably operated nodes, and the authorization node is a professional user node with consensus authority.
In detail, the system node may be a node that can always run online stably in the peer-to-peer network, and belongs to a node that is deployed to ensure that data storage can be performed normally at any time, and thus the system node usually has no corresponding professional or professional. Correspondingly, the authorization node is a professional user node with a consensus right in the peer-to-peer network, that is, the authorization node corresponds to a professional unit or a professional person, and the online state of the authorization node is controlled by the corresponding user. In addition, the above-mentioned professional user refers to an entity or an individual who participates in the chip development and chip transaction process.
In the second embodiment, the composition of the at least two consensus nodes may be implemented in two ways.
In a possible implementation manner of the second aspect, the at least two common nodes do not include a system node.
In detail, because the system nodes are nodes which can always run stably on line, and the number, the running stability and the safety of the system nodes are all reliably ensured, the nodes are selected from the system nodes as consensus nodes, all the consensus nodes are ensured to belong to the system nodes, and the stability of the consensus process of the consensus nodes can be ensured.
In a second aspect, there may be embodiment three described below.
EXAMPLE III
The third embodiment is basically the same as the second embodiment, and the same parts are not described again, except that: the selecting the at least two consensus nodes from the at least two system nodes and the at least one authorized node comprises: screening at least one target authorization node from at least one authorization node, wherein the probability of selecting any authorization node as the target authorization node is in direct proportion to the participation degree corresponding to the authorization node, and the participation degree is determined by the online time and/or the evaluation score of the authorization node; determining the at least two system nodes and the at least one target authorizing node as the at least two consensus nodes.
It should be noted that all target authorized nodes selected from the authorized nodes are in an online state, and the authorized nodes in a non-online state are not selected as the target authorized nodes, so that the subsequent fast consensus process can be performed normally.
For each authorization node, the longer the online time of the authorization node is, the longer the accumulated time for the authorization node to participate in consensus or perform chip development transaction is, the higher the credibility of the authorization node is. In addition, after the authorization node participates in chip development or chip transaction each time, the authorization node is scored according to the actual completion condition of the chip development or chip transaction, and the higher the accumulated evaluation score of the authorization node is, the better the credit of the authorization node is. Therefore, the corresponding participation degree can be determined according to the online time length and the evaluation score of the authorization node, and the higher the online time length and the higher the evaluation score are, the higher the participation degree of the authorization node is, the higher the credibility of the authorization node with the higher corresponding participation degree is.
When the consensus node is selected from the authorization nodes, the probability that the authorization node with higher corresponding participation degree is selected as the consensus node is higher, but the authorization node with higher corresponding participation degree is not directly selected as the consensus node according to the sequence of the corresponding participation degrees from high to low, so that the fairness of selecting the consensus node from the authorization nodes can be ensured.
In addition, a target authorization node is selected from the authorization nodes, the target authorization node and all system nodes are determined to be consensus nodes, the reliability of the consensus result can be guaranteed due to the existence of the system nodes, and part of the authorization nodes are selected to be used as the consensus nodes to participate in the consensus process, so that the consensus power of the consensus process and the consensus result can be improved.
By combining the two aspects, the node can be selected from the system node only as the consensus node, and the system node and the target authorized node selected from the authorized nodes can also be used as the consensus node, so that the method for selecting the consensus node can be flexibly determined according to the requirements in the actual service implementation process, and the flexibility of consensus can be improved.
Example four
The fourth embodiment is basically the same as the third embodiment, and the same parts are not described again, except that: the method for performing at least one hash operation on the block head by sequentially and circularly utilizing the at least two consensus nodes comprises the following steps:
respectively generating point reward transaction information corresponding to each consensus node, wherein for any consensus node, when the consensus node is a system node, the point reward transaction information corresponding to the consensus node comprises a reward point value and a reward node identifier, the reward node identifier is used for identifying one target authorization node, and when the consensus node is an authorization node, the point reward transaction information corresponding to the consensus node comprises a reward point value;
according to the predetermined node sorting result, each common node carries out at least one hash operation on the corresponding block head in sequence to obtain at least one hash value,
for any first common recognition node in the at least two common recognition nodes, obtaining a first block main body corresponding to the first common recognition node by packaging point reward transaction information corresponding to the first common recognition node and all transaction data and all intelligent contract message data generated in the preset time period, where a first block head corresponding to the first common recognition node includes a hash value of the first block main body, a hash value of a last block on the block chain, and an autonomous mining random number, and the autonomous mining random number changes according to a preset rule, so that when the first block head is subjected to hash operation by the first common recognition node at different times, the first block head includes different autonomous mining random numbers.
For example, the 100 consensus nodes perform hash operation on the block heads corresponding to the consensus nodes in sequence for 10 times according to the determined node sorting result, and perform hash operation on the block heads each time to obtain a corresponding hash value until the consensus nodes calculate a hash value smaller than the autonomous mining target value.
And aiming at any one common node X, when the common node X is subjected to Hash operation according to the node sorting result, the common node X is subjected to Hash operation for 10 times on the corresponding block head X. The block header X may include information such as a hash value of a corresponding block body, a hash value of a last block of the block chain, an autonomous mining random number, a version number, a timestamp, and an autonomous mining target value. The consensus node X performs a hash operation on each pair of the block heads X, and the autonomous ore mining random number in the block head X is incremented by 1, for example, when the consensus node X performs the hash operation on the block head X for the first time, the autonomous ore mining random number included in the block head X is 0, when the consensus node X performs the hash operation on the block head X for the second time, the autonomous ore mining random number included in the block head X is 1, when the consensus node X performs the hash operation on the block head X for the third time, the autonomous ore mining random number included in the block head X is 2, and so on. For another example, no hash value smaller than the autonomous mining target value is calculated in the hash operation performed by each of the common identification nodes before, and when the common identification node X performs the fifth hash operation on the block head X, the calculated hash value is smaller than the autonomous mining target value, and all the common identification nodes stop performing the hash operation on the block head. The consensus node X is the accounting node.
In detail, when the consensus node performs the hash operation on the block header, a POW (Proof of work) algorithm may be specifically used to perform the hash operation on the block header.
In this embodiment, for any one of the consensus nodes, the block header corresponding to the consensus node includes the hash value of the corresponding block body and the autonomous mining random number. Because the credit reward transaction information generated by different consensus nodes can be different, the hash values of the corresponding block bodies corresponding to the different consensus nodes are different, so that the hash values obtained by performing hash operation on the corresponding block heads by the different consensus nodes are different. In addition, for the same block head, since the self-service ore digging random number in the block head changes after the corresponding consensus node performs the hash operation on the block head every time, the self-service ore digging random numbers included in the block head in any two times of hash operations are different, and thus different hash values can be obtained by different times of hash operations of the same consensus node.
And each consensus node sequentially and circularly carries out Hash operation on the corresponding block head, and the consensus node which preferentially calculates the Hash value smaller than the autonomous mining target value is determined as an accounting node, so that the time required by electing the accounting node can be shortened, namely, the rapid consensus is realized, and the consensus efficiency is improved. In addition, the probability that the hash value smaller than the autonomous mining target value is calculated by each consensus node is the same, so that the fairness among the consensus nodes in the consensus process is ensured, and the reliability of the consensus process can be ensured.
EXAMPLE five
The fifth embodiment is basically the same as the fourth embodiment, and the same parts are not described again, except that: the method may further comprise: and arranging the at least one target authorization node behind the at least two system nodes according to the sequence of the corresponding participation degrees from large to small, and obtaining the node ordering result according to the arrangement sequence of the common nodes.
Since the system node has high credibility and participates in consensus in the generation process of each block, the system node is arranged in front of each target authorized node. The participation degree of the target authorization nodes can represent the credibility of the target authorization nodes, and the higher the participation degree is, the higher the credibility of the corresponding target authorization nodes is, so that the target authorization nodes with higher corresponding participation degrees are arranged behind the system nodes according to the sequence of the corresponding participation degrees from large to small, the target authorization nodes with higher corresponding participation degrees can preferentially perform hash operation on the target authorization nodes with lower corresponding participation degrees, on one hand, the fairness of the consensus process is ensured, and on the other hand, the safety of the consensus result is ensured.
EXAMPLE six
The sixth embodiment is basically the same as the fourth embodiment, and the same parts are not described again, except that: after the determining the target consensus node as the accounting node, further comprising: when the accounting node is a system node, issuing points corresponding to a first reward point value to a target authorization node identified by a first reward node identification according to the first reward point value and a first reward node identification included in point reward transaction information corresponding to the accounting node; and when the accounting node is an authorized node, issuing points corresponding to a second reward point value to the accounting node according to the second reward point value included in the point reward transaction information corresponding to the accounting node.
And when the system node is determined as the accounting node, the point is issued to a target authorization node randomly determined by the accounting node according to the point reward transaction information generated by the accounting node. And when the target authorization node is determined as the accounting node, distributing the points to the accounting node according to the point reward transaction information generated by the accounting node, wherein the points are used as rewards for generating a new block and carrying out uplink processing.
By generating point reward transaction information and after determining the accounting node, points are issued to an authorization node participating in the consensus process according to the point reward transaction information, the points can improve the participation degree of the nodes, and can be used as virtual currency for currency payment in chip research and development and chip transaction processes, so that the authorization node can be stimulated, the authorization node is ensured to actively participate in the consensus process, and the consensus process can be ensured to be normally carried out.
EXAMPLE seven
The seventh embodiment is basically the same as the fourth embodiment, and the same parts are not described again, except that: the storing all transaction data and all intelligent contract message data generated in the preset time period into a block chain comprises the following steps: generating a new block, wherein the new block comprises a block head and a block main body, the accounting node performs hash operation on the block head of the new block to obtain a hash value smaller than the autonomous mining target value, and the block main body of the new block is a block main body corresponding to the accounting node; linking the new block to the block chain.
Since the self-service ore excavation random numbers in the block heads are different when the same consensus node performs hash operation on the block heads each time, the block heads corresponding to the accounting nodes which calculate the hash values smaller than the self-service ore excavation target values need to be obtained. In addition, the block body comprises the point reward transaction information corresponding to the accounting node, so that the point reward transaction information is also stored in the block chain, and the point reward transaction information can be read from the block chain subsequently to trace the point method process, so that the fairness of the point method process is ensured.
Example eight
The eighth embodiment is substantially the same as the first embodiment, and the same parts are not described again, except that: before the acquiring transaction data, intelligent contract message data and chip development data generated by performing each chip development transaction within a preset time period, further comprising: for any transaction node in the transaction node cluster, when the first transaction node broadcasts at least one chip research and development transaction requirement aiming at a first chip research and development transaction target, executing the following steps aiming at each chip research and development transaction requirement: according to an intelligent contract stored on a block chain and aiming at a first chip research and development transaction target, when a first chip research and development transaction aiming at a current chip research and development transaction requirement is determined between a first transaction node and a second transaction node, transaction data, intelligent contract message data and chip research and development data aiming at the first chip research and development transaction are obtained.
