Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The blockchain is a distributed account book technology, and is an application set of computer information technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The method has the advantages of decentralized trust, non-tampering traceability, transparent account book disclosure and the like, and the method of the embodiment of the invention is based on the block chain and also has the advantages.
The super ledger framework Fabric is a mature alliance chain bottom layer framework, and alliance chain basic components such as block chain nodes, intelligent contracts, transaction processing and certificate management are achieved. The method of the embodiment of the invention can be applied to the Fabric of the super book framework.
The Fabric framework flow is described below. The Fabric framework provides only a fixed transaction flow, namely:
1. the initiating node submits a transaction proposal to all endorsement nodes;
2. the endorsement node receives and verifies the transaction proposal;
3. the endorsement node uses a private key thereof to digitally sign the verified proposal and sends back to the initiating node;
4. the initiating node waits and collects a plurality of endorsement node signatures;
5. the initiating node submits the transaction and all endorsement signatures to the sequencing node;
6. the sequencing node generates a new block after sequencing the transactions and issues all the nodes;
7. all nodes receive 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 result.
The performance of the existing alliance chain realized by using the Fabric framework is still far from the performance of the traditional centralized application, and the alliance chain is difficult to adapt to high-frequency calling. The following embodiments of the present invention are illustrated by way of example in the Fabric framework of a federation chain, and it is to be understood that the present invention is not so limited.
As shown in fig. 1, an embodiment of the present invention provides a transaction information processing method based on a blockchain, which is applied to an initiating node in the blockchain, and includes:
and step 13, under the condition that the proposal type of the transaction proposal is confirmed to be a verifiable transaction, sending the transaction proposal to a sequencing node in the block chain.
Among them, the transaction proposal types can be divided into two categories, which are defined as follows:
1. the transaction may not be verified. The type of transaction refers to that the member of the alliance chain writes new data into the account book through a transaction proposal. All members can not effectively verify the validity of the transaction data according to the existing data in the local account book.
2. The transaction may be verified. The type of transaction refers to the verifiable modification of account data by the members of the federation chain through a transaction proposal. That is, all members can effectively verify the validity of the transaction according to the existing data in the local account book.
According to the scheme, the initiating node in the block chain receives the transaction proposal and confirms the proposal type of the transaction proposal according to the local ledger data; and in the case that the proposal type of the transaction proposal is confirmed to be a verifiable transaction, sending the transaction proposal to a sequencing node in the blockchain. In the embodiment of the invention, the transaction proposal is directly sent to the sequencing node for the verifiable transaction type, so that an endorsement authorization process is not needed, communication is reduced, and the processing performance of a block chain on transaction information is improved. The embodiment of the invention provides a set of brand-new transaction flow, so that part of transactions without endorsement authorization can use a new flow with less communication and higher performance, thereby greatly improving the performance of a block chain when processing the transactions.
Optionally, after confirming the proposal type of the transaction proposal according to the local ledger data, the method further includes: and updating the local ledger data according to the transaction proposal.
In the embodiment of the invention, the initiating node submits a transaction proposal to the sequencing node, the sequencing node sequences the transaction to generate a new block and sends all the nodes down; all nodes receive 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 result.
Optionally, after confirming the proposal type of the transaction proposal according to the local ledger data, the method further includes:
in the event that the proposal type of the transaction proposal is confirmed to be a non-verifiable transaction, the proposal transaction is sent to all endorsement nodes in the blockchain.
Optionally, after sending the proposed transaction to all endorsement nodes in the blockchain according to the local ledger data, the method further includes:
receiving an endorsement signature returned by an endorsement node in a block chain;
and in the case that the number of endorsement signatures is greater than the threshold, sending the transaction proposal and all received endorsement signatures to the ordering node.
In embodiments of the invention, in the event that the proposal type of the transaction proposal is a non-verifiable transaction, the proposal transaction is sent to all endorsement nodes in the blockchain. The endorsement node receives and verifies the transaction proposal; the endorsement node uses a private key thereof to digitally sign the verified proposal and sends back to the initiating node; after the initiating node waits for and collects a plurality of endorsement node signatures, submitting the transaction and all endorsement signatures to a sequencing node; the sequencing node generates a new block after sequencing the transactions and issues all the nodes; all nodes receive 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 result.
As shown in fig. 2, an embodiment of the present invention further provides a transaction information processing method based on a blockchain, which is applied to a sorting node in the blockchain, and includes:
and step 22, generating a target block after sequencing the transaction proposals, and sending the target block to all nodes in the block chain, wherein the transaction proposals are recorded in the target block.
In the embodiment of the invention, the sequencing node generates a new block after sequencing the transaction and issues all the nodes, thereby completing the recording of the transaction information. In the embodiment of the invention, for the transaction which can be verified in the proposal type, the initiating node can directly send the transaction proposal to the sequencing node, and the sequencing node still sequences the transaction proposal and generates the block under the condition that the transaction proposal sent by the initiating node is received and the endorsement signature is not sent, so that the endorsement authorization process is not needed, the communication is reduced, and the processing performance of the block chain on the transaction information is improved.
Optionally, after receiving the transaction proposal sent by the initiating node, the method further includes:
under the condition that the endorsement signature is not sent by the initiating node, acquiring an intelligent contract of the block chain;
and under the condition that the intelligent contract allows the initiating node to directly send the transaction proposal to the sequencing node, executing the step of generating the target block after sequencing the transaction proposal.
In the embodiment of the invention, a configuration item can be newly added to the intelligent contract to control whether the function of the method flow is started. Therefore, for the condition that all transactions require endorsement, the user can close the flow of the method through the configuration items of the intelligent contract. And if the intelligent contract is not configured with the opening, the sequencing node refuses to accept the transaction proposal without the endorsement node signature.
The present invention will be described below by way of examples.
1. Three banks B1-B2-B3 form a alliance chain, respectively have peer nodes, and realize a cross-bank transfer service through an intelligent contract C with a new process opened. The initial account book is empty:
{}
2. the user P1 opens the service account at the B1 counter and stores it in 100 yuan. At this time, B1 constructs a transaction proposal directed to smart contract C, which contains the data:
{ P1 has deposit 100 Yuan at B1, account number P1A }
And submitted to the peer node of B1. The peer node judges whether to be according to the existing account book data:
{}
and judging that the validity of the transaction cannot be verified, and guiding the transaction to the original flow, namely submitting the sequencing node after requesting endorsement signatures to the nodes B2 and B3.
3. User P2 opens the service account at the B2 counter and does not deposit money. At this time, B1 constructs a transaction proposal directed to smart contract C, which contains the data:
{ P2 has deposit 0 Yuan at B2, account number P2A }

{ P1 has deposit 100 Yuan at B1, account number P1A }
And judging that the validity of the transaction cannot be verified, and guiding the transaction to the original flow, namely submitting the sequencing node after requesting endorsement signatures to the nodes B1 and B3.
4. The user P1 initiates a transfer transaction through B1, transferring 50 dollars to P2. At this time, B1 constructs a transaction proposal directed to smart contract C, which contains the data:
{ P1 transfer 50 Yuan to P2 }
And submitted to the peer node of B1. The peer node judges whether to be according to the existing account book data:
{ P1 has deposit 100 Yuan at B1, account number P1A }
{ P2 has deposit 0 Yuan at B2, account number P2A }
And judging that the validity of the transaction can be verified, and guiding the transaction to a new process, namely directly submitting the sequencing node to write in a new block.
When all nodes receive the new block, the data of the local existing account book are basically:
{ P1 has deposit 100 Yuan at B1, account number P1A }
{ P2 has deposit 0 Yuan at B2, account number P2A }
The transaction validity can be verified, the transaction is confirmed, and the local account book is updated as follows:
{ P1 has 50 Yuan of deposit at B1, account number P1A }
{ P2 has 50 Yuan of deposit at B2, account number P2A }
5. The user P1 again initiates a transfer transaction through B1, transferring 150 dollars to P2. Node B1 is based on local ledger data:
{ P1 has 50 Yuan of deposit at B1, account number P1A }
{ P2 has 50 Yuan of deposit at B2, account number P2A }
And judging that the transaction is illegal and directly refusing.
