Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Some embodiments of the present application provide a method for processing a multi-chain-based blockchain transaction, which is applied to a node device in a blockchain network including a plurality of parallel chains. When generating a creation block of a blockchain, a node device in the blockchain network stores multi-chain configuration information in the creation block, wherein the multi-chain configuration information comprises configuration information of each chain, and the configuration information of each chain at least comprises a chain identifier of each chain.
For example, assuming that three chains, i.e., chain1, chain2, and chain3, are included in the blockchain, chain1 may be included in the multi-chain configuration information stored in the created block: id-123, chain 2: id-456, chain 3: id-567.
In the embodiment of the present application, there may be two or more parallel chains in the block chain system, and the application does not limit the number of parallel chains in the block chain, and the number of parallel chains may be determined according to requirements in practical applications. Only the configuration information corresponding to each chain needs to be stored in the creation block.
In this embodiment of the present application, each node device can only assume the role of one of the chains when being started, and can only serve as a node on one of the parallel chains, and when being started, the node device binds the node identifier of the node device and the chain identifier corresponding to the parallel chain to which the node device belongs together through configuration. The blocks generated by the node device in a packed mode can only be stored in the block chain corresponding to the chain to which the node device belongs.
As shown in fig. 1, chain identifications of three chains, namely chain1, chain2 and chain3, are stored in the created Block, and each chain generates a respective Block chain along with service processing, for example, a Block chain corresponding to chain1 in fig. 1 includes a Block from chain1 to Block1, a Block chain corresponding to chain2 includes three blocks from chain2 to Block1, chain2 to Block2 and chain2 to Block3, and a Block chain corresponding to chain3 includes two blocks from chain3 to Block1 and chain3 to Block 2.
In the blockchain system, the node device generating the created block broadcasts the multi-link configuration information stored in the created block to each node device in the blockchain system. Each node device is thus aware that there are multiple parallel chains in the current network.
Different node devices in the block chain system communicate with each other through a point-to-point Protocol, which may be a TCP (Transmission Control Protocol) Protocol. The node device searches its own neighbor node through a point-to-point protocol, and records the found neighbor node in its own neighbor list (neighbor table). In order to ensure that a plurality of parallel chains in a block chain system operate smoothly and orderly, each node device needs to find out at least one node of each chain when searching for a neighbor node.
Since the process of searching for the neighbor node by each node device is the same, the embodiment of the present application only uses the first node device as an example to describe the search process, and the first node device may be any node device in the blockchain system. Specifically, the first node device sends a neighbor searching request to each second node device, and the second node devices are node devices directly connected to the first node device. The second node device returns the node identifier of the neighbor node recorded in the neighbor list of the second node device and the chain identifier to which the node identifier belongs to the first node device. After the first node device receives the node identifiers and the chain identifiers of the neighbor nodes returned by each second node device, only one of the repeated node identifiers is reserved, and other repeated node identifiers are removed. And storing the rest node identifications and the corresponding chain identifications in a neighbor list of the node, and marking the node identifications of the neighbor nodes which establish the connection relation with the node identifications.
The second node device also obtains the node identifiers of the neighbor nodes from the node devices directly connected with the second node device, and all the node devices in the block chain system are directly or indirectly interconnected, so that the first node device can be ensured to obtain the node identifiers of the node devices on each chain by the above mode.
To facilitate understanding of the above process of finding neighboring nodes, the following detailed description is provided by way of example in conjunction with the accompanying drawings. As shown in fig. 2, the bidirectional arrows between different node devices in the figure indicate that a point-to-point communication connection is established between two node devices. Node 1: chain1 denotes a Node equipment Node1 on Chain1, with Node 1: chain1 is taken as an example, Node 1: chain1 is directly connected to Node2: Chain2, Node4: Chain1 and Node3: Chain 3. Node 1: chan 1 sends neighbor search request to Node2: Chan 2, Node4: Chan 1 and Node3: Chan 3 respectively. Node2, Chan 2, Node4, Chan 1 and Node3, Chan 3 all send Node identifiers and corresponding Chain identifiers in their neighbor lists to Node 1: chain 1. Finally, Node 1: the Chain1 records its own neighbor list as:
Chain1:Node4(connected),Node6
Chain2:Node2(connected),Node5,
CHain3:Node3(connected),Node7。
wherein connected represents that Node 1: the Chain1 is directly connected.
Since network resources are limited, the number of neighbor nodes to which the node device is directly connected is generally less than the number of neighbor nodes recorded in the neighbor list. Because more candidate neighbor nodes are recorded in the neighbor list, when the connection between the node device and a directly connected neighbor node is interrupted due to network instability or neighbor node failure, the node device may select a candidate neighbor node from a plurality of unconnected neighbor nodes in its own neighbor list, and send a connection request to the candidate neighbor node, so as to establish a communication connection with the candidate neighbor node. After establishing communication connection with the candidate neighbor node, a connection identifier is also marked for the node identifier corresponding to the candidate neighbor node in the neighbor list.
After the blockchain system including a plurality of parallel chains is established in the above manner, transaction processing is performed based on the blockchain system, which is shown in fig. 3, and the method specifically includes the following steps:
step 101: the node device receives a transaction processing request, wherein the transaction processing request comprises a transaction identifier, an account address of a transfer party, a transaction amount, a transaction signature, a public key and transaction expiration time.
When a user needs to perform a transaction, a transaction processing request is sent to any node device in the blockchain system. The node equipment receives a transaction processing request sent by a user, and analyzes a transaction identifier, an account address of a transfer party, a transaction amount, a transaction signature, a public key, transaction expiration time and the like from the transaction processing request. The transaction signature can be a ciphertext obtained by performing hash operation on transaction information such as a transaction identifier, an account address of a transfer party, a transaction amount, transaction expiration time and the like to obtain a transaction hash value, and then encrypting the transaction hash value by using a private key.
For example, assume that the node device receives a transaction processing request corresponding to transaction Tx0001, transaction Tx0001 contains the following information:
{"params":{"from":"addressFrom","to":"addressTo","account":100},
"signature":"sdfosdg","pubkey":"sdfsdgtt","expireTimestamp":2021/08/23 14:51:39}
wherein, the address from is the address of the transfer party account, the address to is the address of the transfer party account, the account 100 is the transaction amount, the sdfosdg is the transaction signature, the sdfsgtt is the public key, and the expireTimestamp 2021/08/2314, 51 and 39 are the transaction expiration time.
After receiving the transaction processing request, the node device first determines whether the transaction corresponding to the transaction processing request is an effective transaction based on the transaction signature.
Specifically, the node device decrypts the transaction signature by using the public key included in the transaction processing request, and obtains the transaction hash value. And carrying out hash operation on transaction information including the transaction identification, the transfer party account address, the transaction amount, the transaction expiration time and the like included in the transaction processing request to generate a transaction hash value. And comparing whether the currently generated transaction hash value is the same as the transaction hash value obtained by decryption in the transaction signature, and if the currently generated transaction hash value is the same as the transaction hash value obtained by decryption in the transaction signature, determining that the transaction corresponding to the transaction processing request is an effective transaction. Otherwise, determining that the transaction corresponding to the transaction processing request is an invalid transaction.
If a valid transaction is determined, the node device forwards the transaction processing request to a neighboring node directly connected to the node (excluding the neighboring node that forwarded the transaction processing request to the current node), and determines whether the current node device is capable of processing the transaction by the following manner of step 102. If an invalid transaction is determined, the transaction processing request is discarded.
Step 102: and the node equipment respectively determines the chain identification of the parallel chain where the transfer party is positioned and the chain identification of the parallel chain where the transfer party is positioned according to the account address of the transfer party, the account address of the transfer party and the preset number of the parallel chains.
And the node equipment utilizes the account address of the transfer party to carry out remainder taking operation on the number of the preset parallel chains, and the obtained remainder is used as the chain identification corresponding to the parallel chain where the transfer party is located. And performing remainder taking operation on the number of the preset parallel chains by using the account address of the transfer party, and taking the obtained remainder as the chain identifier corresponding to the parallel chain where the transfer party is located.
Step 103: and the node equipment determines the processing measures to be taken for the transaction processing request according to the chain identification corresponding to the roll-out party, the chain identification corresponding to the roll-in party and the chain identification corresponding to the node equipment.
And the node equipment judges whether the chain identification corresponding to the roll-out party is the same as the chain identification corresponding to the roll-in party. If the determined chain identification corresponding to the transfer-out party is the same as the chain identification corresponding to the transfer-in party, the transaction is only processed by the parallel chain corresponding to the chain identification, and the transaction belongs to single-chain transaction. In this case, the node device determines whether the chain identifier corresponding to the roll-out party and the roll-in party is the same as the chain identifier of the parallel chain to which the node device belongs, and if so, determines that the node device can process the transaction processing request, and the processing measures taken for the transaction processing request include a roll-out operation and a roll-in operation. If not, determining that the node equipment cannot process the transaction processing request, and taking a processing measure for the transaction processing request to discard the transaction processing request.
And if the chain identification corresponding to the transfer-out party is different from the chain identification corresponding to the transfer-in party, the transaction is indicated to be cooperatively processed by two different parallel chains, and the transaction belongs to cross-chain transaction. In this case, the node device determines whether the chain identifier of the parallel chain to which the node device belongs is a chain identifier corresponding to the roll-out party or a chain identifier corresponding to the roll-in party. And if the self corresponding chain identification is judged to be the chain identification corresponding to the roll-out party, determining that the node equipment can process the transaction processing request, and the processing measure is roll-out processing of roll-out transaction amount from the roll-out party account address. And if the self corresponding chain identification is judged to be the chain identification corresponding to the transfer-in party, determining that the node equipment can process the transaction processing request, and the processing measure is transfer-in processing for adding the transaction amount in the account address of the transfer-in party. And if the self corresponding chain identification is judged to be neither the chain identification corresponding to the transfer-out party nor the chain identification corresponding to the transfer-in party, determining that the node equipment cannot process the transaction processing request, wherein the processing measure is to discard the transaction processing request.
For example, suppose the node device calculates the address from% of the roll-out party account by a preset number of parallel chains chainNum, and the obtained chain identifier is id-123, i.e. the roll-out party belongs to chain 1. And calculating the address addressTo% of the account of the transfer party to preset the number of parallel chains, namely chainNum, and obtaining a chain identifier of id-456, namely that the transfer party belongs to chain 2. And if the link identifier corresponding to the node equipment is id-456, determining that the node equipment can execute the processing of increasing the transaction amount in the account address of the transfer party.
Step 104: and the node equipment executes the transaction processing operation corresponding to the determined processing measure on the transaction processing request.
If the processing measure determined in step 103 is discarding processing, the node device discards the transaction processing request and does not perform other processing except forwarding broadcast on the transaction processing request.
If the transaction is determined to be a single-chain transaction in step 103 and the determined processing measures include roll-out processing and roll-in processing, the node device first determines whether the transaction processing request has expired. Specifically, the node device acquires the timestamp of the last block from the local chain, determines whether the transaction expiration time included in the transaction processing request is earlier than the timestamp of the last block, and if so, determines that the transaction has expired, discards the transaction processing request, and does not perform subsequent processing any more.
If the transaction is judged to be not expired, the transaction amount included by the transaction processing request is subtracted from the transfer-out account address included by the transaction processing request, and the transaction amount is added to the transfer-in account address. The node device packages the transaction results into a new block after processing is complete and stores the new block on the local link. The local chain of the node device is a block chain corresponding to the parallel chain to which the node device, the roll-out party and the roll-in party belong.
After the uplink storage, the node device further sends the new block to each of the other node devices belonging to the same parallel chain in the block chain system, so that each of the other node devices stores the new block in the respective local chain.
If it is determined in step 103 that the transaction is a cross-link transaction and the determined processing measure includes roll-out processing, the node device also determines whether the transaction processing request is expired according to the above-mentioned manner, and the specific determination process is not described herein again. If the transaction processing request is not expired, the transaction amount included in the transaction processing request is subtracted from the roll-out account address included in the transaction processing request. The node apparatus packs a new block after the out-of-process is completed, and stores the new block in the local chain. The local chain of the node device is a block chain corresponding to a parallel chain to which the node device and the forwarding party belong.
After the uplink storage, the node device further sends the new block to each of the other node devices belonging to the same parallel chain in the block chain system, so that each of the other node devices stores the new block in the respective local chain.
If it is determined in step 103 that the transaction is a cross-link transaction and the determined processing measure includes a transfer-to-process, the node device also determines whether the transaction processing request is expired according to the above-mentioned manner, and the specific determination process is not described herein again. And if the transaction processing request is not expired, adding the transaction amount included in the transaction processing request from the transfer-in account address included in the transaction processing request. The node apparatus packs a new block after the transfer process is completed, and stores the new block in the local chain. The local chain of the node device is a block chain corresponding to a parallel chain to which the node device and the transfer-in party belong.
After the uplink storage, the node device further sends the new block to each of the other node devices belonging to the same parallel chain in the block chain system, so that each of the other node devices stores the new block in the respective local chain.
In the application scenario of the cross-chain transaction, there may be a case where the parallel chain responsible for executing the roll-out process has completed the roll-out process, and the parallel chain responsible for executing the roll-in process fails to execute the roll-in process. When this occurs, a compensation operation needs to be performed on the roll-out account address to re-transfer the amount of the transaction that has been rolled out to the roll-out account address.
In order to deal with the above situation, in the embodiment of the present application, if the processing measure determined in step 103 is roll-out processing, the node device needs to perform real-time monitoring on a parallel chain executing the roll-in operation while executing the roll-out operation according to the above manner, so as to determine whether the roll-in operation is successfully executed.
Specifically. And the node equipment determines the node identifier corresponding to the link identifier from the neighbor list of the node equipment according to the link identifier corresponding to the transfer party. If the node identifier marked with the connection identifier exists in the node identifiers corresponding to the chain identifiers, the node device periodically sends a monitoring request to the neighbor node device marked with the connection identifier and corresponding to the node identifier, and the monitoring request carries the transaction identifier corresponding to the transaction processing request. If the node identifier marked with the connection identifier does not exist in the node identifier corresponding to the chain identifier of the transfer-in party in the neighbor list, the node device firstly randomly selects one node identifier from the node identifiers corresponding to the chain identifier of the transfer-in party, establishes communication connection between the node device and the neighbor node device corresponding to the selected node identifier, and then periodically sends a monitoring request to the neighbor node device. After receiving the monitoring request, the neighbor node device searches whether a block corresponding to the transaction identifier is included in the local chain according to the transaction identifier included in the monitoring request.
Since there is a block rollback in the blockchain, since consensus in the blockchain is delayed, it usually takes 15-20 blocks to confirm 99.9999999% success in Taifang. The number of security blocks for each parallel chain, which may be 6, 10, 15, or 20, etc., may be set according to the consensus policy of each parallel chain itself.
The neighbor node device may calculate a difference value by subtracting the number of security blocks corresponding to the parallel chain in which the neighbor node device is located from the total number of current blocks. And searching whether the block corresponding to the transaction identifier is included in the previous difference blocks in the local chain. If yes, the transfer-in processing is determined to be successful, and a transfer-in success notification is sent to the current node equipment executing the transfer-out processing. If not, determining that the transfer-in processing fails, and sending a transfer-in failure notice to the current node equipment.
And after receiving a transfer-in failure notification returned by the neighbor node device, the current node device sends a transaction failure message to the user, wherein the transaction failure message is used for prompting the user to reinitiate a compensation transaction request corresponding to the transaction, and the compensation transaction request comprises a transaction signature, a public key and a transaction identifier corresponding to the transaction processing request.
For example, compensation transactions include the following:
{"params":{"from":"addressFrom","compensate_tx":"Tx0001"},"signature": "sdfosdg","pubkey":"sdfsdgtt"}
wherein, addressFrom is the transfer account address, Tx0001 is the transaction identifier, sdfosdg is the transaction signature, and sdfsdgtt is the public key.
After receiving the compensation transaction request, the node device first determines whether the compensation transaction request is valid based on a transaction signature included in the compensation transaction request. The specific determination process is the same as the process of determining whether the transaction processing request is valid in step 101, and is not described herein again.
If the compensation transaction request is judged to be valid, the compensation transaction request is forwarded to the adjacent node directly connected with the compensation transaction request (wherein the transaction processing request is not forwarded to the adjacent node of the current node), so that other node devices can synchronously process the compensation transaction request.
And then the node equipment performs remainder operation on the number of the preset parallel chains by using the account address of the transfer party included in the compensation transaction request, and the obtained remainder is used as the chain identifier corresponding to the parallel chain where the transfer party is located. And searching a block corresponding to the transaction identifier in the local chain according to the transaction identifier included in the compensation transaction request. And acquiring the transferred account address and the transaction amount from the searched block, performing remainder taking operation on the number of the preset parallel chains by using the transferred party account address, and taking the obtained remainder as the chain identifier corresponding to the parallel chain where the transferred party is located. And according to the chain identifier corresponding to the transfer-in party, determining the neighbor node equipment corresponding to the chain identifier for establishing communication connection from the neighbor list. And determining whether the transfer-in operation corresponding to the transaction identifier fails to be processed from the neighbor node device according to the monitoring mode. And after the transfer-in operation processing is determined to fail, adding the transaction amount corresponding to the transaction identification in the transfer-out account address.
The node equipment packages the new block after processing the supplementary transaction and stores the new block on the local link. And the local chain of the node equipment is a block chain corresponding to the parallel chain to which the node equipment and the roll-out party belong.
After the uplink storage, the node device further sends the new block to each of the other node devices belonging to the same parallel chain in the block chain system, so that each of the other node devices stores the new block in the respective local chain.
The method and the device for configuring the block chain have the advantages that the multi-chain information is configured in the creation block, the multi-chain configuration information is broadcast to each node device in the block chain system, and each node device finds out neighbor nodes on each chain, so that the block chain running in the multi-chain mode can be realized. The single-chain transaction can be processed through the block chain running in a multi-chain mode, cross-chain transactions involving multiple chains can be processed, the flexibility of processing the transactions by the block chain is improved, the universality of the block chain is improved, and application scenes suitable for the block chain are increased. And through multi-chain operation, different processing processes of the same transaction can be executed in parallel on different parallel chains, so that the processing time of the transaction is shortened, the processing efficiency of the blockchain on the transaction is improved, and the throughput rate of the blockchain is greatly improved. Further, for cross-chain transactions, the parallel chain executing the roll-out processing also monitors the parallel chain executing the roll-in processing in real time to acquire the execution state of the roll-in processing. After the transfer-in processing fails, the transfer-out account address is compensated by initiating the compensation transaction, so that the accuracy of the cross-chain transaction is ensured, and benefit loss caused by asynchronism of processing operations among different parallel chains is avoided.
