Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the protection of the present application.

Nodes can divide nodes into two different roles according to their computing power. Nodes with larger computing power can prove transactions between nodes in the entire system, which can be called proof nodes (such as nodes that win the right to bookkeeping); Nodes with less computing power that conduct computing power transactions can be called transaction nodes. Two types of roles can coexist on the same node, which can be called transaction nodes/proof nodes. The specific distribution of nodes in the network is shown in Figure 2, and the proof nodes can be set to obtain transaction commissions, and the transaction nodes pay commissions by initiating transaction requirements. Among them, the computing power of a node can be measured by the comprehensive capability of the node, which can include storage capability, computing capability, and network connection capability.

A transaction node (or "demand node") can issue a computing power transaction request. The computing power transaction request can include computing power demand and computing power quotation, and the computing power demand can include information such as transaction type, computing power to be traded, and node account amount. Among them, the transaction type includes the type of computing power to buy or the type of computing power to sell, so the computing power to be traded can be the amount of computing power to be bought or the amount of computing power to be sold. After the computing power transaction request is released, the proving node will give a computing power transaction scheme according to the transaction requirements in the computing power transaction request. The computing power transaction scheme is a combination scheme of at least one processing node in the network. The nodes that trade computing power charge transaction commissions, and then publish the computing power trading plan, and the proof nodes with accounting rights record the computing power trading plan into the blockchain. The demand node and the processing node establish a computing power circulation channel according to the transaction scheme, and finally combine the computing power trading scheme with the smart contract to complete the final computing power circulation transaction.

It can be seen that the computing power transaction process in the above network does not depend on a specific node. This application does not have strict requirements on the type of resources that provide computing power, which can make resources of different computing types common, and can avoid the waste of computing resources to the greatest extent.

FIG. 4 is a schematic flowchart of a blockchain-based computing power circulation method provided by an embodiment of the present invention. As shown in Figure 4, the method may include:

Step 410: The demand node issues a computing power transaction request.

The computing power transaction request may include information such as the transaction type, the computing power to be traded, the identification of the demanded node, the public key of the demanded node, the credit rating of the demanded node, and the transaction implementation commission of the demanded node. Among them, the transaction type includes the type of computing power to buy or the type of computing power to sell, so the computing power to be traded includes the amount of computing power to be bought or the amount of computing power to be sold.

Before performing this step, the demand node collects the computing power and computing power reference quotations of each network node, and stores them. Each network node includes a processing node and a demand node; the processing node is at least one of the network nodes processing the computing power to be traded. Nodes, processing nodes can collect the information of this node, and broadcast and output the information of the tradable computing power of this node.

The demand node obtains the computing power demand, which includes the transaction type, the computing power to be traded by the demand node, and the account amount of the demand node;

In order to improve the accuracy of computing power transactions, the transaction computing power and the total computing power of the storage processing nodes, as well as the account amount of the demand node and the computing power reference quotation are respectively verified.

If the computing power to be traded is within the range of the total computing power of the processing nodes, and the account amount of the demanded node meets the computing power reference quotation, a reasonable commission for transaction implementation will be allocated, and then the computing power transaction request of the demanded node will be issued; If it is not within the range of the total computing power of the processing node and/or the account amount of the demand node does not meet the computing power reference quotation, it will refuse to issue a computing power transaction request, or output an alarm of wrong demand.

Step 420: The proof node determines the computing power transaction scheme based on the computing power transaction request and the stored computing power of each node in the network.

Before executing this step, in order to improve the accuracy of computing power transactions, it is necessary to verify whether the credit level of the demand node meets the preset credit level, verify whether the computing power to be traded is within the range of the total computing power of the stored processing nodes, and whether the demand node Whether the account amount meets the computing power reference quotation.

If the credit level of the verification demand node does not meet the preset credit level, the verification to-be-transaction computing power is not within the range of the total computing power of the stored processing nodes, and/or the account amount of the demand node does not meet the computing power reference quotation, the transaction error will be output. 's warning.

If it is verified that the credit level of the demand node satisfies the preset credit level, the computing power to be traded is within the range of the total computing power of the stored processing nodes, and the account amount of the demand node meets the computing power reference quotation, then based on the computing power transaction request, from In each node of the stored network, a combination scheme of processing nodes that satisfies the computing power to be traded is searched as a computing power trading scheme.

The computing power transaction scheme includes the transaction type, the computing power to be traded, the identification of the demanded node, the public key of the demanded node, and the node information of the processing node. The node information of the processing node includes the node identification of the processing node and the computing power of the processing node. It can be seen that the computing power transaction scheme is a computing power transaction between a demand node and at least one processing node, that is, a one-to-many computing power transaction relationship, which avoids business coupling.

Optionally, in order to reduce the waste of resources, the processing node combination scheme with the least resource waste among the processing node combination schemes satisfying the computing power to be traded is selected as the computing power transaction scheme.

For example, the transaction type of the demand node is to buy storage computing power, and the computing power to be traded is to buy 4M of storage computing power. In each node of the storage network, processing node A has a storage computing power of 3M, processing node B has a storage computing power of 2M, and processing node C has a storage computing power of 1M. The processing node combination scheme that satisfies the purchase of 4M storage computing power includes: the combination of processing node A and processing node B, and the combination of processing node A and processing node C. The storage computing power of the combination of processing node A and processing node B is 5M, and the storage computing power of the combination of processing node A and processing node C is 4M. It can be seen that the combination of processing node A and processing node B will have 1M. Therefore, the optimal computing power transaction scheme is the combination of processing node A and processing node C.

Further, after the computing power trading plan is determined, the computing power trading plan is uploaded to the blockchain for transaction confirmation, and then the transaction implementation commission is charged.

Step 430: The processing node acquires the computing power output information based on the node identifier.

The node information of the processing node may include the identification of the processing node and the computing power of the processing node.

Regularly query the computing power transaction scheme confirmed on the blockchain, and obtain the computing power output information of the processing node's output computing power when the node ID is queried. The computing power output information is the information encrypted with the public key of the demand node, and the computing power output information may be the computing power output interface of the processing node.

Based on the computing power output information of each processing node, establish a computing power circulation channel between the demand node and each processing node, so as to conduct computing power circulation transactions.

Step 440: The processing node and the demand node execute a preset smart contract based on the computing power transaction scheme and the computing power output information, and generate transaction information, where the transaction information includes transaction data and transaction results.

The demand node receives the computing power output information broadcast by the processing node, and uses its own private key to decrypt the received computing power output information;

Based on the decrypted computing power output information, the demand node and the processing node establish a computing power circulation channel, execute the computing power transaction plan and preset smart contracts on the computing power circulation channel, generate transaction information, and complete the final computing power circulation transaction.

Compared with the prior art that only uses computing power to perform hash value operation, this step uses the computing power in the computing power transaction scheme to execute the preset smart contract through the established computing power circulation channel between the demand node and each processing node, so as to realize Diversification of computing power usage.

Further, after the transaction information is generated, the processing node uploads the transaction information to the blockchain, and collects the current computing power of the processing node and the demand node for storage update.

The method issues a computing power transaction request based on the computing power demand of the demand node, and the computing power transaction request includes the transaction type, the computing power to be traded, and the identification of the demanded node; Power trading scheme, the computing power trading scheme includes the transaction type, the computing power to be traded, the identification of the demanded node and the node information of the processing node. The processing node is at least one node processing the computing power to be traded in each node of the network; , to obtain the computing power output information of the processing node; based on the computing power transaction plan and computing power output information, execute the preset smart contract to generate transaction information, which includes transaction data and transaction results.
