Example 1
As shown in fig. 1, the present embodiment provides a method for performing a blockchain transaction, which is applied to any light node in a blockchain network, where the light node is a node that does not participate in consensus in the blockchain network, and the method includes steps S1 and S2.
Step S1, a light node sends first transaction data to a first consensus node, wherein the first consensus node is any one of a plurality of consensus nodes, the first transaction data is data reflecting transaction details, the first transaction data is used for triggering the first consensus node to send first consensus data to a master node, the first consensus data is the first transaction data containing voting results of the plurality of consensus nodes, the master node is used for distributing first execution data to the plurality of consensus nodes, and the first execution data comprises the first consensus transaction data;
in this embodiment, after receiving the first transaction data, the first consensus node signs the first transaction data, then sends the signed first transaction data to each consensus node, each consensus node votes according to the transaction content, and feeds the voting result back to the first consensus node, the consensus nodes collect a plurality of voting results and package the voting results together with the first transaction data to obtain first consensus data, and send the first consensus data to the master node, it should be noted that the master node receives the consensus data sent by the plurality of consensus nodes in unit time, the first consensus data is only one of the plurality of consensus data, the master node sorts the plurality of consensus data, the sorted plurality of consensus data (including the first consensus data) is marked as first execution data, the master node sends the first execution data to each consensus node, after receiving the execution data, the consensus node sequentially executes a plurality of consensus data in the first execution data, so that the final execution results of the nodes are consistent, and the consistency of the public account book is further ensured;
it should be noted that, in the whole block chain transaction execution, when the master node sends execution data, it is necessary to confirm that each consensus node receives the execution data before sending the next execution data, and the more consensus nodes, the longer the time consumed for sending the execution data and ensuring that each consensus node receives the execution data, so the present invention adopts a part of authoritative nodes in the block chain network as the consensus nodes, and the other nodes as light nodes, which greatly reduces the number of nodes participating in consensus, makes the consensus speed faster, and effectively avoids the problem that the transaction consensus time is longer and longer with the addition of more and more organization nodes, and further the service capability of the block chain network is reduced.
Step s2, synchronizing a block header of a public ledger of a second consensus node, where the second consensus node is a consensus node that receives a ledger synchronization request, the second consensus node may be any one of a plurality of consensus nodes, the block header is ledger data including a block height and a block hash, it should be noted that the block-chain public ledger includes a plurality of blocks, each block is composed of a block header and a block body, the block body includes details (service data) of specific contents of each service transaction, the data size is relatively large, one of the block header information includes data of state-root, the data is used to record root hashes of all service state changes under the block, and the correctness of the service data state changes can be calculated and verified by using RLP hash values of an MPT tree (Merkle-PatricaTrie), so as to achieve the purpose of verifying consensus, the light nodes only synchronously store the block header information, so that the time consumption of executing data (second-level consensus) sent by the master node by each node in the block chain network is further reduced, and the problems that the transaction consensus consumes longer and longer time and the service capability of the block chain network is reduced due to the addition of more and more mechanism nodes are solved.
Secondly, the light node does not accept the execution data sent by the master node, so that a complete public account book cannot be obtained, the light node only stores block header information, and the block header information requests and synchronizes the block header data in the public account book of the common node without judging by the light node, so that the block header of the light node is synchronized with the block header information of other common nodes in the block chain network.
As shown in fig. 2, in an embodiment of the present disclosure, the specific operation of synchronizing the block header of the common ledger of the second consensus node in step S2 includes step S21, step S22 and step S23.
Step s21, the light node sends an account book synchronization request to the second consensus node, where the second consensus node may be any node in the consensus nodes, and the account book synchronization request is used to trigger the second consensus node to send block header data of current blocks of multiple consensus nodes to the light node, and the specific implementation manner may be:
the second common identification node sends a block head request instruction to other common identification nodes in the block chain network after receiving the account book synchronous request of the light node, the other common identification nodes send block head data of a block with the highest current height in the common account book to the second common identification node after receiving the block head request instruction, and the second common identification node packs the block head data of the block with the highest current height sent by the common identification nodes to obtain the block head data of the current blocks and forwards the block head data to the light node.
S22, receiving block header data of a plurality of current blocks sent by the second consensus node;
and S23, generating a new block head by the node according to the block head data of the current blocks.
The light node can sequentially judge the height of each block head data, if the block heights and the hash values in the block head data of a plurality of current blocks are the same, the current block heights of a plurality of common nodes are the same, the block data of the heights are the same, the fed back data is credible data, and then the block head data of the current block is copied and recorded as a new block head.
In an embodiment of the present disclosure, after the step S2, the method for the light node to verify whether the first transaction data submitted by the light node is accurately executed according to the transaction details includes steps S24, S25 and S26.
S24, calling the first transaction data, wherein the first transaction data comprises a first transaction identifier and a first transaction detail, and the transaction identifier can be a transaction ID and is unique;
step S25, generating a first transaction query instruction according to the first transaction identifier and sending the first transaction query instruction to a third consensus node, wherein the third consensus node can be any one of a plurality of consensus nodes, the first transaction query instruction is used for triggering the third consensus node to send first account book block data of the plurality of consensus nodes to a light node, the first account book block data is account book block data corresponding to the first transaction identifier, the account book block data comprises a plurality of transaction details, and each transaction detail corresponds to one transaction identifier;
the block data comprises block body data and block head data, and the block body data comprises detailed transaction details.
Step S26, whether second transaction details in each corresponding account book block data are the same as the first transaction details is detected in sequence, and if the second transaction details are the same as the first transaction details, it is determined that the first transaction data are executed without errors.
