Technical field

The present invention relates to the field of blockchain technology, and in particular, to a method, system, electronic device and computer readable storage medium for transaction on a blockchain.

Background technique

When a smart contract is placed on a blockchain, one issue that must be considered is the management of permissions. The smart contract itself is a series of code running on the blockchain network, so there are many application programming interfaces (APIs) in the smart contract. How to manage which API can be used by which user is a problem often mentioned in the blockchain field. One of the mainstream solutions is to write user rights in a digital certificate that has been certified by a Certification Authority (CA) and then send it to the user. When a user wants to initiate a transaction for a smart contract, the user will send the signed transaction and certificate together to the smart contract, and the smart contract will check the permissions on the certificate to decide whether to continue running.

However, user rights are not permanent. In the Public Key Infrastructure (PKI) system, the revocation list of certificates is stored in a central control system, if the nodes on the blockchain are to verify whether a certificate is verified. Have authority (the purpose of verifying the certificate is to determine whether to permit the execution of a transaction), the node on the blockchain must check from the CA through a trusted mechanism whether the certificate is revoked, which makes each transaction happen, It is necessary to obtain the latest certificate revocation list through the central control system to determine whether the transaction related party has the right to trade, which makes the transaction operation cumbersome and the system overhead.

The system on the blockchain transaction is implemented by the processor 12: after the certificate revocation list is released to the blockchain, the blockchain synchronizes it to each node of the blockchain, that is, the certificate revocation list is directly stored in In the blockchain, when the smart contract receives the transaction request, the certificate revocation list can be obtained in real time directly on the blockchain, and the transaction request and the certificate revocation list carried in the transaction request are revoked according to the accessed authority. The authority to verify, does not need to query the transaction authority from the CA through a trusted mechanism, making the transaction operation simple and fast, reducing system overhead.

As shown in FIG. 2, FIG. 2 is a schematic flowchart of an embodiment of a method for transaction on a blockchain according to the present invention. The method for transaction on the blockchain is applied to an electronic device, and includes the following steps:

Step S1, after the certificate certification authority issues the certificate revocation list to the blockchain, the blockchain synchronizes the certificate revocation list to each node of the blockchain;

Blockchain is composed of a series of data blocks generated by cryptography. Each block contains the hash of the previous block, starting from the genesis block. To the current block, form a blockchain. The blockchain is also a distributed database system involving nodes. It is essentially a decentralized database book that records all transaction records. Take the bitcoin blockchain as an example. Each participating trader is a block network. Nodes, each node has a complete public account book backup that records all transaction information since the birth of Bitcoin. Any node initiated transaction behavior needs to pass relevant information to each node in the block network, so that the books on all nodes can verify the transaction behavior and update accurately. In addition, the books are stored in partition blocks. As the transaction increases, new data blocks are attached to the existing chains to form a chain structure.

After the certificate authority issues the certificate revocation list to the blockchain, the blockchain can use its peer-to-peer (P2P) network and consensus algorithm to synchronize the certificate revocation list to each node of the blockchain. On the other hand, the certificate revocation list is spread to each node of the blockchain. The certificate revocation list contains the information of the revoked certificate revoked by the certificate authority and the revoked certificate information that has not been revoked. If the certificate information has been revoked, there is no right to execute the corresponding smart contract, that is, there is no permission to conduct the transaction. If the certificate information has not been revoked, that is, in the certificate revocation list Without the certificate information, there is permission to execute the corresponding smart contract, that is, the right to conduct the transaction.

In addition, the revoked certificate information in the certificate revocation list may change. At this time, the certificate authority will issue an updated certificate revocation list to the blockchain, and the blockchain will replace the stored certificate revocation list with the update. The subsequent certificate revocation list, or change the stored certificate revocation list based on the updated certificate revocation list.

Step S2, after the smart contract on the node receives the transaction request carrying the transaction parameter, accessing the authority revocation system on the blockchain, based on the authority revocation system, the transaction parameter, and the node The certificate revocation list verifies the authority of the transaction request, and responds or refuses to respond to the transaction request according to the verification result.

In this embodiment, each node on the blockchain stores a smart contract on the running blockchain. A smart contract is a set of promises defined in digital form, including the contract participants can implement these commitments on them. Agreement. When a transaction request carrying a transaction parameter is transmitted to a node of the blockchain, the transaction parameter is recorded on the transaction record corresponding to the node and simultaneously transmitted to the smart contract corresponding to the transaction parameter to run, and The code on the smart contract corresponding to the transaction parameter updates the smart contract's own data.

The transaction parameters include certificate information and corresponding certificate authority, and the certificate information includes a certificate authority, a certificate serial number, a certificate validity period, and a certificate owner user information.

After the smart contract on the node receives the transaction request carrying the transaction parameter, the system revokes the system by accessing the authority on the blockchain to obtain the certificate information and the corresponding certificate authority in the transaction parameter, but the transaction parameter may have the certificate authority. It is also possible that there is no certificate authority. The privilege revocation system is used to handle related privilege issues, such as the privilege revocation system can perform parsing of transaction parameters. When verifying the authority of the transaction request, if the certificate information and the certificate authority can be obtained from the transaction parameter, the certificate information is compared with the revoked certificate information in the certificate revocation list on the node corresponding to the smart contract, Verify that the certificate information is the revoked certificate information. If the certificate information is the revoked certificate information, the transaction request has no permission to conduct the transaction. If the certificate information is not the revoked certificate information, the transaction request has the right to conduct the transaction.

Compared with the prior art, after the certificate revocation list of the embodiment is released to the blockchain, the blockchain synchronizes it to each node of the blockchain, that is, the certificate revocation list is directly stored in the blockchain, when the smart contract is When receiving the transaction request, the certificate revocation list can be obtained in real time directly from the blockchain, and the transaction request and the certificate revocation list carried in the transaction request are verified according to the accessed authority revocation system, and the permission of the transaction request is verified. The authority of the transaction is queried from the CA through a trusted mechanism, which makes the transaction operation simple and quick, and reduces system overhead.

In a preferred embodiment, as shown in FIG. 3, based on the foregoing embodiment of FIG. 2, the foregoing step S2 further includes:

S21: parsing the transaction parameter by using the privilege revocation system;

S22, when parsing the certificate information and the certificate authority, analyzing whether the certificate information belongs to the revoked certificate information in the certificate revocation list, to verify the authority of the transaction request;

S23. If the certificate information belongs to the revoked certificate information in the certificate revocation list, rejecting the response to the transaction request;

S24. If the certificate information belongs to the revoked certificate information in the certificate revocation list, respond to the transaction request.

In this embodiment, if the smart contract running or stored on the node of the blockchain receives the transaction request carrying the transaction parameter, the authorization revocation system on the blockchain chain may be accessed through the predetermined address to request the transaction. The permission is verified. Specifically, when accessing the authority revocation system on the blockchain, the transaction revocation system analyzes the transaction parameters. If the certificate information is parsed but the certificate authority is not resolved, the transaction request is If there is no permission to conduct the transaction, the smart contract rejects the transaction request; if the certificate information and the certificate authority are obtained, the certificate information is further analyzed whether the certificate information belongs to the revoked certificate information in the certificate revocation list. Specifically, the certificate information and the certificate revocation list may be The revoked certificate information is compared one by one to determine whether the certificate information belongs to the revoked certificate information in the revocation list. If the certificate information belongs to the revoked certificate information in the certificate revocation list, the transaction request has no permission to conduct the transaction, and the smart contract refuses to respond to the transaction request; if the certificate information does not belong to the revoked certificate information in the certificate revocation list, the transaction request Have permission to trade, smart contract responds to the transaction request.

In addition, if the certificate information can only be parsed from the transaction parameters, but the certificate authority is not obtained after parsing, the transaction request has no permission to conduct the transaction.

In the embodiment, when verifying the authority of the transaction request, by accessing the authority revocation system on the blockchain, the authority revocation system parses the transaction parameters, and when analyzing the certificate information and the certificate authority, analyzes whether the certificate information belongs to The certificate revocation information in the certificate revocation list is used to verify the authority of the transaction request, which can improve the transaction data processing rate.

In a preferred embodiment, as shown in FIG. 4, on the basis of the foregoing embodiment of FIG. 3, the certificate revocation list may also record information about whether the sub-rights corresponding to the unrevoked certificate information are revoked. In the embodiment, if it is detected that the certificate information does not belong to the revoked certificate information in the certificate revocation list, the step S24 may further include the following steps:

Step S241: Compare each sub-rights corresponding to the unrevoked certificate information with the certificate authority corresponding to each unrevoked certificate information in the certificate revocation list, and determine whether the sub-rights have been revoked. If yes, go to step S242, otherwise, go to step S243.

Step S242, responding to the transaction request.

Step S243, refusing to respond to the transaction request.

In this embodiment, the information in the certificate revocation list records whether the sub-rights corresponding to the unrevoked certificate information are revoked, that is, the information that the sub-rights have been revoked or not revoked is recorded.

In this embodiment, a certificate information corresponds to multiple sub-rights. In order to enable the user to perform other certificate authority transactions on the blockchain through the certificate information after the partial rights are revoked, the embodiment records in the certificate revocation list. If the certificate information is not revoked, if the certificate information is not revoked, the license rights corresponding to the revoked certificate information in the certificate revocation list are further respectively performed. Compare, if there is decentralization If the limit is not revoked, the transaction request is responded to, and if the rights are revoked, the transaction request is refused.
