[0037] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] Blockchain is a distributed ledger technology, which is a collection of computer information technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. It has the advantages of decentralized trust, tamper-proof traceability, and open and transparent ledgers. The method of the embodiment of the present invention is based on blockchain and also has these advantages.

[0039] Hyperledger Fabric is a mature alliance chain underlying framework that implements alliance chain basic components such as blockchain nodes, smart contracts, transaction processing, and certificate management. The method of the embodiment of the present invention can be applied to Hyperledger Fabric.

[0040] The following is an explanation of the Fabric framework process. The Fabric framework only provides a fixed transaction process, namely:

[0041] 1. The initiating node submits the transaction proposal to all endorsing nodes;

[0042] 2. The endorsing node receives the transaction proposal and verifies it;

[0043] 3. The endorsing node uses its own private key to digitally sign the verified proposal and sends it back to the initiating node;

[0044] 4. The initiating node waits and collects enough signatures from endorsing nodes;

[0045] 5. The initiating node submits the transaction and all endorsement signatures to the sorting node;

[0046] 6. The sorting node sorts the transactions and generates a new block, which is then sent to all nodes;

[0047] 7. All nodes accept the new block, verify the transactions in the block one by one according to the local ledger data, mark success / failure, and update the local ledger data based on the results.

[0048] The performance of the existing alliance chain implemented using the Fabric framework is still far behind that of traditional centralized applications, and it is difficult to adapt to high-frequency calls. The following embodiments of the present invention are illustrated by taking the Fabric framework of the alliance chain as an example, but it is understood that the present invention is not limited to this.

[0049] like Figure 1 As shown, an embodiment of the present invention provides a transaction information processing method based on blockchain, which is applied to an initiating node in a blockchain, including:

[0050] Step 11, receiving transaction proposal;

[0051] Step 12: Confirm the proposal type of the transaction proposal based on the local ledger data;

[0052] Step 13, when confirming that the proposal type of the transaction proposal is a verifiable transaction, the transaction proposal is sent to the sorting node in the blockchain.

[0053] Among them, transaction proposal types can be divided into two categories, which are defined as follows:

[0054] 1. Unverifiable transactions. This type of transaction refers to the consortium chain members writing new data into the ledger through transaction proposals. All members cannot effectively verify the legitimacy of the transaction data based on the existing data in the local ledger.

[0055] 2. Verifiable transactions. This type of transaction refers to the consortium chain members making verifiable changes to the ledger data through transaction proposals. That is, all members can effectively verify the legitimacy of the transaction based on the existing data in the local ledger.

[0056] In the above scheme of the present invention, the initiating node in the blockchain receives the transaction proposal, and confirms the proposal type of the transaction proposal based on the local account book data; when the proposal type of the transaction proposal is confirmed to be a verifiable transaction, the transaction proposal is sent to the sorting node in the blockchain. In the embodiment of the present invention, for the proposal type of a verifiable transaction, the transaction proposal is directly sent to the sorting node, thereby eliminating the need for an endorsement authorization process, reducing communications, and improving the blockchain's processing performance for transaction information. The embodiment of the present invention provides a new set of transaction processes, allowing some transactions that do not require endorsement authorization to use new processes with less communication and higher performance, thereby greatly improving the performance of the blockchain when processing such transactions.

[0057] Optionally, after confirming the proposal type of the transaction proposal according to the local ledger data, the above method also includes: updating the local ledger data according to the transaction proposal.

[0058] In an embodiment of the present invention, the initiating node submits a transaction proposal to the sorting node, which sorts the transactions and generates a new block, which is then distributed to all nodes; all nodes accept the new block, verify the transactions in the block one by one according to the local ledger data, mark success / failure, and update the local ledger data based on the results.

[0059] Optionally, after confirming the proposal type of the transaction proposal according to the local ledger data, the method further includes:

[0060] When the proposal type of the transaction proposal is confirmed to be a non-verifiable transaction, the proposal transaction is sent to all endorsing nodes in the blockchain.

[0061] Optionally, after sending the proposal transaction to all endorsing nodes in the blockchain according to the local ledger data, the method further includes:

[0062] Receive the endorsement signature returned by the endorsing node in the blockchain;

[0063] When the number of endorsement signatures is greater than the threshold, the transaction proposal and all received endorsement signatures are sent to the sorting node.

[0064] In an embodiment of the present invention, when the proposal type of the transaction proposal is a non-verifiable transaction, the proposed transaction is sent to all endorsing nodes in the blockchain. The endorsing node receives the transaction proposal and verifies it; the endorsing node uses its own private key to digitally sign the verified proposal and sends it back to the initiating node; after the initiating node waits for and collects enough signatures from the endorsing nodes, it submits the transaction and all endorsement signatures to the sorting node; the sorting node sorts the transactions and generates a new block, which is sent to all nodes; all nodes accept the new block, verify the transactions in the block one by one according to the local ledger data, mark success / failure, and update the local ledger data according to the results.

[0065] like Figure 2 As shown, an embodiment of the present invention further provides a transaction information processing method based on blockchain, which is applied to an ordering node in a blockchain, comprising:

[0066] Step 21, receiving the transaction proposal sent by the initiating node;

[0067] Step 22, after sorting the transaction proposals, a target block is generated and sent to all nodes in the blockchain, wherein the target block records the transaction proposals.

[0068] In the embodiment of the present invention, the sorting node sorts the transaction and generates a new block, which is sent to all nodes to complete the recording of transaction information. In the embodiment of the present invention, for the proposal type of verifiable transaction, the initiating node can directly send the transaction proposal to the sorting node. After receiving the transaction proposal sent by the initiating node and without sending the endorsement signature, the sorting node still sorts the transaction proposal and generates a block, thereby eliminating the need for an endorsement authorization process, reducing communication, and improving the blockchain's processing performance for transaction information.

[0069] Optionally, after receiving the transaction proposal sent by the initiating node, it also includes:

[0070] Obtain the smart contract of the blockchain when the initiating node does not send the endorsement signature;

[0071] When the smart contract allows the initiating node to send the transaction proposal directly to the sorting node, the step of sorting the transaction proposal and generating the target block is performed.

[0072] In the embodiment of the present invention, a new configuration item can be added to the smart contract to control whether to enable the function of the above method flow. Therefore, in the case where all transactions require endorsement, the user can turn off the above method flow through the configuration item of the smart contract. If the smart contract is not configured to enable this item, the sorting node will refuse to accept transaction proposals without the signature of the endorsing node.

[0073] The present invention is described below by way of examples.

[0074] 1. Banks B1, B2 and B3 form a consortium chain, each with its own peer node, and implement an inter-bank transfer business through a smart contract C that opens a new process. The initial ledger is empty:

[0075] {}

[0076] 2. User P1 opens an account for this service at counter B1 and deposits 100 yuan. At this time, B1 constructs a transaction proposal pointing to smart contract C, including data:

[0077] {P1 has a deposit of 100 yuan in B1, account number is P1A}

[0078] And submit it to the peer node of B1. The peer node judges based on the existing ledger data:

[0079] {}

[0080] The legality of the transaction is judged to be unverifiable, and the transaction is directed to the original process, that is, requesting endorsement signatures from nodes B2 and B3 and then submitting it to the sorting node.

[0081] 3. User P2 opens the business account at counter B2 without depositing money. At this time, B1 constructs a transaction proposal pointing to smart contract C, including data:

[0082] {P2 has a deposit of 0 yuan in B2, account number is P2A}

[0083] And submit it to B2's peer node. The peer node determines based on the existing ledger data:

[0084] {P1 has a deposit of 100 yuan in B1, account number is P1A}

[0085] The legality of the transaction is judged to be unverifiable, and the transaction is directed to the original process, that is, requesting endorsement signatures from nodes B1 and B3 and then submitting it to the sorting node.

[0086] 4. User P1 initiates a transfer transaction through B1 and transfers 50 yuan to P2. At this time, B1 constructs a transaction proposal pointing to smart contract C, including data:

[0087] {P1 transfers 50 yuan to P2}

[0088] And submit it to the peer node of B1. The peer node judges based on the existing ledger data:

[0089] {P1 has a deposit of 100 yuan in B1, account number is P1A}

[0090] {P2 has a deposit of 0 yuan in B2, account number is P2A}

[0091] It is determined that the legitimacy of the transaction can be verified, and the transaction is directed to a new process, that is, directly submitting it to the sorting node and writing it into a new block.

[0092] When all nodes receive the new block, the existing local ledger data is:

[0093] {P1 has a deposit of 100 yuan in B1, account number is P1A}

[0094] {P2 has a deposit of 0 yuan in B2, account number is P2A}

[0095] The legitimacy of the transaction can be verified, the transaction is confirmed, and the local ledger is updated as follows:

[0096] {P1 has a deposit of 50 yuan in B1, account number is P1A}

[0097] {P2 has a deposit of 50 yuan in B2, account number is P2A}

[0098] 5. User P1 initiates a transfer transaction through B1 again, transferring 150 yuan to P2. Based on the local ledger data, B1 node:

[0099] {P1 has a deposit of 50 yuan in B1, account number is P1A}

[0100] {P2 has a deposit of 50 yuan in B2, account number is P2A}

[0101] The transaction is judged to be illegal and rejected directly.
