Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For ease of understanding, two technical concepts, BFT (Byzantine factory Tolerance) and federation chains are first introduced. The Byzantine fault-tolerant technology BFT is a fault-tolerant technology in the field of distributed computing, the Byzantine assumption in the technology is real-world modeling, and unexpected behaviors of a computer and a network can occur due to hardware errors, network congestion or interruption, malicious attack and the like. Byzantine fault tolerance techniques are designed to handle these abnormal behaviors and meet the specification requirements of the problem to be solved.
A federation chain is essentially a private chain, except that a federation chain is larger than a private chain developed by a single small organization, but not as large as a public chain, it being understood that it is a block chain between a private chain and a public chain. At present, in the consensus transaction process of the alliance chain, a host node packages the whole transaction and issues a consensus proposal. This approach generally causes two problems: firstly, if the transaction amount in the chain is too large, for example, the transaction amount in a unit time period reaches one hundred thousand, the network bandwidth can be easily filled and the message broadcasting speed can be rapidly reduced, and as long as the network shakes, the consensus timeout can be easily caused; second, transaction verification is performed by the consensus master node, and when other consensus nodes receive a block (also called a block) proposal, in order to save time, the transactions in the block are usually not checked repeatedly, so that if the master node does bad, a security problem occurs. In this embodiment, the master node may also be referred to as a leader node or a master node.
Based on the above, embodiments of the present invention provide a transaction consensus method, an apparatus, and an electronic device, where the technology may be applied to a transaction consensus process of various block chains, such as a federation chain, a private chain, and a public chain. To facilitate understanding of the embodiment, a detailed description will be given of a transaction consensus method disclosed in the embodiment of the present invention.
The method is applied to the main nodes in the block chain, the main nodes in the block chain can be selected from all the nodes in the block chain, and all the nodes in the block chain can be alternately used as the main nodes under the control of a certain selection algorithm; the main node stores the transaction to be identified; the main node can be provided with a transaction pool, and the transaction pool stores transactions received by the main node from the client and also includes transactions broadcasted by other nodes; specifically, each node in the block chain is provided with a transaction pool, and the transaction pool of each node stores transactions received by the node from the client and also includes transactions broadcasted by other nodes; for example, for node a, after receiving transaction B from the client, the node checks and stores the transaction B in the transaction pool of node a, then broadcasts the transaction B in the blockchain, so that other nodes also receive transaction B, and after checking and storing the transaction B in their respective transaction pools by other nodes. Thus, in an ideal situation, the transactions held in the transaction pool of each node in the blockchain are identical; the transaction pool of each node transaction holds the transactions to be identified.
As shown in fig. 1, the transaction consensus method includes the following steps:
step S102, determining a target transaction from the transactions to be identified;
the main node is used for triggering a transaction consensus process, the transactions to be consensus can be stored in a transaction pool of the main node, and the transactions to be consensus can be stored in the transaction pool in a queue form. The main node selects a certain number of transactions from the transactions to be identified as the target transactions; in most cases, the number of target transactions selected at one time by the master node is plural, but may be one.
Step S104, generating a transaction block based on the transaction hash value of the target transaction;
in the related technology, after a certain number of target transactions are determined from the transactions to be identified, the complete transaction content of the target transactions is packaged to generate transaction blocks; typically, the transaction content of a transaction includes a variety of data, particularly an input data portion, which is created by, or invoked by, the smart contract code. In most cases, the data size of one transaction can reach 500 bytes, if a transaction block needs to pack 10 ten thousand transactions, the data size of the transaction block can reach 50M, and the bandwidth requirement is very high when a transaction area with such a large data size is broadcast in a block chain. Thus, in the case of a relatively large transaction amount, the consensus process can easily time out at the network level.
In this embodiment, the complete transaction content is not packaged any more, but a transaction block is generated based on the transaction hash value of the target transaction; the transaction block does not comprise the complete transaction content of the target transaction and only comprises the content related to the transaction hash value of the target transaction; in a specific implementation manner, the transaction block includes a transaction hash value of the target transaction; in other ways, other identifying information related to the transaction hash value of the target transaction, such as the encrypted transaction hash value, may also be included in the transaction block. Therefore, the embodiment can greatly reduce the data volume of the transaction block and reduce the problem of consensus timeout.
Step S106, the transaction block is broadcasted to the nodes except the main node in the block chain, so as to perform consensus processing on the transaction in the transaction block.
After the data volume of the transaction block is reduced, even if the network is crowded or network jitter occurs, the transaction block can be stably broadcast to other nodes except the main node in the block chain; taking a node A in other nodes as an example, the transaction block received by the node A only includes the content related to the transaction hash value of the target transaction; because the transaction pool of the node a contains the same to-be-consensus transaction as that in the transaction pool of the master node, the node a can obtain the complete transaction content of the target transaction from the transaction pool of the node a based on the content related to the transaction hash value of the target transaction in the transaction block, and then perform subsequent consensus processing, such as a commit stage, an execute stage, and the like.
In the transaction consensus method, after a target transaction is determined from the transactions to be agreed, a transaction block is generated based on a transaction hash value of the target transaction; and then broadcasting the transaction block to nodes except the main node in the block chain so as to perform consensus processing on the transaction in the transaction block. In the mode, the transaction block is generated based on the transaction hash value of the target transaction, the data volume of the transaction block can be greatly reduced, even under the condition of large transaction volume, the transaction block can be quickly and stably broadcast to each node in the block chain, and the transaction consensus efficiency is improved.
As described in the previous embodiments, each node broadcasts a transaction to other nodes in the blockchain after receiving the transaction from the client, and thus, in most cases, the transactions held in the transaction pool of each node in the blockchain are the same. Therefore, after receiving the transaction block, the node may obtain the transaction content of the target transaction from the local transaction pool of the node based on the transaction hash value of the target transaction in the transaction block. However, in actual implementation, the transaction broadcast is not timely or missed, so that the node does not store all transactions to be identified, and at this time, the node cannot acquire the transaction content of the target transaction from the local transaction pool.
To obtain the transaction content of the target transaction, the other node may send a request to the master node. Specifically, if the transaction content of the target transaction K is not obtained from the local transaction pool, a transaction obtaining request is generated based on the transaction hash value of the target transaction K in the transaction block, where the transaction obtaining request includes the transaction hash value of the target transaction K. For the main node, if a transaction acquisition request sent by a first node except the main node is received, extracting a transaction hash value of a transaction to be acquired from the transaction acquisition request; the transaction to be acquired here belongs to one or more transactions in the target transactions; acquiring transaction content of the transaction to be acquired from the transaction to be identified based on the transaction hash value of the transaction to be acquired; and sending the transaction content of the transaction to be acquired to the first node. Generally, after receiving the transaction content of the transaction to be acquired, the first node performs signature verification on the transaction content of the transaction to be acquired. After the signature is checked, the first node can obtain the transaction content of each transaction in the transaction block, and at this time, a commit stage, an execute stage and the like in the transaction consensus process can be executed.
To further understand the transaction consensus method of the present embodiment, the transaction consensus method is described below from the perspective of the first node except the master node; the method is applied to a first node except a main node in a block chain; the first node stores the transaction to be identified; as shown in fig. 2, the method comprises the steps of:
step S202, if a transaction block sent by the master node is received, a transaction hash value of a target transaction contained in the transaction block is obtained;
the transaction block typically contains transaction hash values of a plurality of target transactions, and the transaction hash values of the plurality of target transactions are stored in the transaction block in a list form, where the list form may be [ hash1, hash2, …, hash ]. Because the transaction block only comprises the transaction hash value, even if the transaction block comprises 10 thousands of transactions, the data volume of one transaction block is usually less than 1M, the data volume of the transaction block is greatly reduced, the transmission of a network layer is facilitated, and the consensus speed can be increased.
Step S204, acquiring the transaction content of the target transaction corresponding to the transaction hash value from the transaction to be identified; and performing consensus processing on the target transaction based on the transaction content of the target transaction.
The local transaction pool of the first node stores the transactions to be identified in the current block link network, so that the first node can acquire the transaction content of the target transaction corresponding to each transaction hash value included in the transaction block from the local transaction pool, and perform identification processing on the target transaction based on the transaction content of the target transaction acquired from the local transaction pool.
It should be noted that, if the master node makes a malicious result and tampers with the transaction content of the target transaction, the first node may detect the hash value of the target transaction in the transaction block; in addition, because the first node is the transaction content of the target transaction acquired from the local transaction pool, even if the master node tampers the transaction content of the target transaction, the first node does not perform subsequent consensus processing, such as commit processing, on the tampered transaction content of the target transaction; the first node uses the transaction content of the target transaction which is not tampered in the local transaction pool to perform subsequent consensus processing, so that the safety of the block chain data is improved.
In the transaction consensus method, if a transaction block sent by a main node is received, a transaction hash value of a target transaction contained in the transaction block is obtained; acquiring the transaction content of the target transaction corresponding to the transaction hash value from the transaction to be identified; and performing consensus processing on the target transaction based on the transaction content of the target transaction. In the mode, the main node generates the transaction block based on the transaction hash value of the target transaction, the data volume of the transaction block can be greatly reduced, even under the condition of large transaction volume, the transaction block can be quickly and stably broadcast to each node in the block chain, each node obtains transaction content from a local transaction pool based on the transaction hash value in the transaction area, the transaction content does not need to be transmitted through a network, and the transaction consensus efficiency is improved.
In addition, the method can also prevent the master node from tampering the transaction content, the first node except the master node uses a local transaction pool, the transaction content of the target transaction which is not tampered is subjected to subsequent consensus processing, even if the master node tampers the transaction content, the subsequent consensus processing based on the tampered transaction content cannot be performed, and the safety of the block chain data is improved.
When the transaction block comprises transaction hash values of a plurality of target transactions, acquiring transaction contents of each target transaction from a transaction pool of the first node aiming at the transaction hash value of each target transaction; in most cases, the first node stores all transactions to be identified, but there may be a few situations where the broadcast is not timely or missed, and at this time, the first node may not store the transaction content of the target transaction.
Based on the above, when the transaction content of the target transaction corresponding to the transaction hash value is obtained, the transaction content of the target transaction corresponding to the transaction hash value is inquired from the transactions to be identified; if the target transaction hash value of which the transaction content cannot be inquired exists in the transaction hash values, generating a transaction acquisition request based on the target transaction hash value; and sending the transaction acquisition request to the main node so as to acquire the transaction content of the transaction corresponding to the target transaction hash value from the main node.
The transaction acquisition request comprises transaction hash values of one or more target transactions which are not inquired from the transaction pool of the first node; after the transaction acquisition request is sent to the main node, the main node acquires the transaction contents of the target transactions from the local transaction pool of the main node and then sends the transaction contents to the first node, so that the first node can obtain the transaction contents of each target transaction in the transaction block, and the subsequent consensus process can be executed after the transaction contents of each transaction in the transaction block are complete.
After the first node sends the request to be acquired to the main node, transaction content of the transaction corresponding to the target transaction hash value returned by the main node can be received; and carrying out signature verification processing on the transaction content of the transaction corresponding to the target transaction hash value. In the block chain, each node needs to check the received transaction, and after the check passes, the transaction can be stored in a local transaction pool; for the transaction contents of the target transactions which are not inquired in the first node, after the transaction contents of the target transactions are obtained from the main node, signature verification processing is required to be carried out, and then the transaction contents can enter a transaction pool of the first node; therefore, for the first node, after the first node acquires the transaction content of the target transaction from the transaction block, if the transaction content of the target transaction is already stored in the transaction pool of the first node, it indicates that the first node has already performed one-time signature verification on the transaction content of the target transaction, and at this time, the transaction content of the target transaction in the transaction block is subjected to one-time signature verification again, which is equivalent to that the first node needs to perform two-time signature verification on the transaction content of the target transaction, so that the time consumption of the consensus process is increased undoubtedly.

In the mode, the transaction block is generated based on the transaction hash value of the target transaction, the data volume of the transaction block can be greatly reduced, even under the condition of large transaction volume, the transaction block can be quickly and stably broadcast to each node in the block chain, and the transaction consensus efficiency is improved.
