The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a transaction information processing method according to an embodiment of the present invention. The embodiment of the invention provides a transaction information processing method aiming at the technical problems in the prior art, which comprises the following specific steps:
As shown in fig. 3, the blockchain network includes a master storage node 31, a master storage node 32, a master storage node 33, a master storage node 34, a slave storage node 41, a slave storage node 42, and a slave storage node 43, which is only illustrated schematically and is not limited to the specific network architecture of the blockchain network. Optionally, each master storage node may be communicatively connected to a plurality of slave storage nodes, for example, the master storage node 31 may be communicatively connected to the slave storage node 41, the slave storage node 42, and the slave storage node 43, and optionally, the master storage node 32 may be communicatively connected to the slave storage node 41, the slave storage node 42, the slave storage node 43, or may be communicatively connected to other slave storage nodes. Similarly, the master storage node 33 and the master storage node 34 may also be communicatively connected with the slave storage node 41, the slave storage node 42, the slave storage node 43, or other slave storage nodes. In addition, the number of slave storage nodes communicatively connected to each master storage node is not limited in this embodiment.
In this embodiment, the identity information of the master storage node needs to be broadcast into the blockchain network, and the identity information and IP address of the master storage node need to be recorded in the foundational block.
When a transaction node first joins the block chain network, a created block needs to be acquired from a node adjacent to the transaction node, and optionally, the created block is stored in all nodes in the block chain network. In order to ensure that the trading node acquires a real created region, the trading node may send created region query requests to a plurality of adjacent nodes, for example, the trading node a first joins the block chain network, the trading node a sends created region query requests to the adjacent node B and the adjacent node C, the adjacent node B and the adjacent node C receive the created region query requests, and then send respective locally stored created regions to the trading node a, the trading node a compares whether created regions fed back by the adjacent node B and the adjacent node C are consistent, if the created regions fed back by the adjacent node B and the adjacent node C are consistent, the trading node a stores the created regions locally; if the created blocks fed back by the adjacent node B and the adjacent node C are not consistent, the trading node A can further continuously send created block query requests to the adjacent node D and the adjacent node E and receive the created blocks fed back by the adjacent node D and the adjacent node E respectively.
When the transaction node A acquires a real created block, the IP address of a main storage node is acquired from the created block, and a first query request is sent to the main storage node according to the IP address of the main storage node, wherein the first query request is used for acquiring the identification information of a plurality of auxiliary storage nodes stored by the main storage node.
As shown in fig. 3, the master storage node 31 locally stores the identification information of the slave storage node 41, the slave storage node 42, and the slave storage node 43, and when the master storage node 31 receives a first query request sent by the transaction node a, the identification information of the slave storage node 41, the slave storage node 42, and the slave storage node 43 is sent to the transaction node a according to the first query request. In the present embodiment, the blockchain ledger is stored in the slave storage node 41, the slave storage node 42, and the slave storage node 43, and the transaction node a may send a second query request to the slave storage node 41, the slave storage node 42, and the slave storage node 43, the second query request being used for querying partial content of the blockchain ledger stored in the slave storage node.
Alternatively, when receiving a second query request sent by the transaction node a from the storage node 41, the storage node 42, and the storage node 43, calculating offer information corresponding to a part of the content of the blockchain book requested to be obtained by the transaction node a according to the data amount of the part of the content, and sending the offer information to the transaction node a, when the transaction node a receives offer information sent from the storage node 41, the storage node 42, and the storage node 43, respectively, determining which slave storage node or slave storage nodes to transfer to according to the offer information of each slave storage node and the reliability of each slave storage node, for example, when the transaction node a determines to transfer to the slave storage node 41 and the slave storage node 42, generating transfer information to the slave storage node 41 and transfer information to the slave storage node 42, and sending the transfer information to the slave storage node 41, the transfer information includes the amount of money transferred from the storage node 41 and the contents of the inquiry required to be provided from the storage node 41; similarly, the transaction node a transmits transfer information to the slave storage node 42, which includes the amount of money transferred to the slave storage node 42 and the contents of the query required to be provided from the slave storage node 42, to the slave storage node 42. Alternatively, the transfer information sent by the transaction node a to the storage node 41 and the storage node 42 may be the transfer information signed by the transaction node a with its own private key.
When the transfer information of the transaction node a is received from the storage node 41 and from the storage node 42, the query content required by the transaction node a or the access address and the access code corresponding to the query content are transmitted to the transaction node a from the storage node 41 and from the storage node 42, respectively. Optionally, the slave storage node 41 signs the query content sent from the storage node 41 to the transaction node a or the access address and the access code corresponding to the query content with the public key of the transaction node a, and sends the signed result to the transaction node a. The slave storage node 42 signs the query content sent from the storage node 42 to the transaction node a or the access address and the access code corresponding to the query content by using the public key of the transaction node a, and sends the signed result to the transaction node a.
In this embodiment, the query content sent from the storage node 41 to the transaction node a, or the query content corresponding to the access address and the access code sent from the storage node 41 to the transaction node a is recorded as a first query result; and recording the query content sent from the storage node 42 to the transaction node a, or the query content corresponding to the access address and the access code sent from the storage node 42 to the transaction node a as a second query result.
After the transaction node a receives the first query result and the second query result, it compares whether the first query result and the second query result are consistent, specifically, the transaction node a compares whether the query content sent from the storage node 41 to the transaction node a is consistent with the query content sent from the storage node 42 to the transaction node a, or the transaction node a compares whether the query content corresponding to the access address and the access code sent from the storage node 41 to the transaction node a is consistent with the query content corresponding to the access address and the access code sent from the storage node 42 to the transaction node a.
If the query content sent from the storage node 41 to the transaction node a is inconsistent with the query content sent from the storage node 42 to the transaction node a, or the query content corresponding to the access address and the access code sent from the storage node 41 to the transaction node a is inconsistent with the query content corresponding to the access address and the access code sent from the storage node 42 to the transaction node a, or access is not possible according to the access address and the access code sent from the storage node 41 or from the storage node 42 to the transaction node a, the transaction node a sends the first query result and the second query result to the main storage node 31.
The main storage node 31 receives the first query result and the second query result sent by the transaction node a.
And step 204, the master storage node determines a slave storage node with lower reliability from the first slave storage node and the second slave storage node by comparing the first query result with the blockchain ledger stored in the master storage node and the second query result with the blockchain ledger stored in the master storage node.
The master storage node 31 compares the first query result with the locally stored blockchain ledger, and compares the second query result with the locally stored blockchain ledger, thereby determining a slave storage node with lower reliability from among the slave storage nodes 41 and 42.
The master storage node determining a slave storage node with lower reliability from the first slave storage node and the second slave storage node by comparing the first query result with the blockchain ledger stored in the master storage node and the second query result with the blockchain ledger stored in the master storage node, including: if the first query result is consistent with the blockchain account book stored in the main storage node, and the second query result is inconsistent with the blockchain account book stored in the main storage node, the main storage node determines that the second slave storage node is a slave storage node with lower reliability in the first slave storage node and the second slave storage node.
For example, after comparing the first query result with the locally stored blockchain ledger, and comparing the second query result with the locally stored blockchain ledger, the master storage node 31 determines that the second query result is not consistent with the locally stored blockchain ledger, and the first query result is consistent with the locally stored blockchain ledger, which indicates that the first query result sent from the storage node 41 to the transaction node a is real, and the second query result sent from the storage node 42 to the transaction node a is false, that is, the slave storage node 42 is a slave storage node with lower reliability.
Optionally, after the master storage node determines that the second slave storage node is a slave storage node with lower reliability in the first slave storage node and the second slave storage node, the master storage node deletes the locally stored identification information of the second slave storage node.
For example, the master storage node 31 may delete locally stored identification information of the slave storage node 42.
Or after the master storage node determines that the second slave storage node is the slave storage node with lower reliability in the first slave storage node and the second slave storage node, the master storage node broadcasts the identification information of the second slave storage node to the blockchain network so as to cancel the transaction information transferred from the transaction node to the second slave storage node.
For example, the master storage node 31 may also broadcast the identification information of the slave storage node 42 into the blockchain network in order to cancel the transaction information transferred by the transaction node a to the slave storage node 42, which is the previously described transfer information of the transaction node a to the slave storage node 42 based on the offer information of the slave storage node 42.
Optionally, after the transaction node a sends the transfer information to the slave storage node 42, the amount transferred to the slave storage node 42 by the transaction node a is transferred to the account of the slave storage node 42 after a preset time, and within the preset time, if the master storage node 31 determines that the slave storage node 42 is a slave storage node with lower reliability, the identification information of the slave storage node 42 may be broadcast to the blockchain network, so as to avoid the transfer of the amount transferred to the slave storage node 42 by the transaction node a to the account of the slave storage node 42. The preset time can be determined according to the data volume of the query result downloaded by the transaction node A, the network speed and other factors. Or, when the transaction node a receives the second query result from the storage node 42 and confirms the second query result, the confirmation information of the second query result is broadcast to the blockchain network, so that the amount transferred from the storage node 42 to the transaction node a is transferred to the account of the storage node 42. In order to avoid that the transaction node a receives the second query result, confirms the second query result and does not broadcast confirmation information of the second query result, a time threshold value may be set in the block chain network, and when the time threshold value is exceeded, the transaction node a also broadcasts the confirmation information of the second query result, and the amount transferred from the storage node 42 by the transaction node a is transferred to the account of the storage node 42.
The embodiment of the invention sends the identification information of a plurality of locally stored slave storage nodes to the transaction node through the master storage node, so that the transaction node sends a query request to at least one slave storage node in the plurality of slave storage nodes to query partial contents of the blockchain ledger stored in the slave storage node, when the query results obtained by the transaction node from different slave storage nodes are different, the transaction node sends the different query results to the master storage node, so that the master storage node determines the slave storage node with lower reliability according to the different query results and the blockchain ledger locally stored by the master storage node, thereby the transaction node obtains the query results from the slave storage nodes with high reliability, and the reliability of the query results is improved.
Fig. 4 is a flowchart of a transaction information processing method according to another embodiment of the invention. On the basis of the foregoing embodiment, the transaction information processing method provided in this embodiment specifically includes the following steps:
As shown in fig. 3, the master storage node 31 may send a second query request to the slave storage node 41, the slave storage node 42, and the slave storage node 43, respectively, the second query request being used for querying partial contents of a target chunk in the blockchain ledger. Optionally, the partial content of the target block includes at least one of: partial transaction information in the target block, target field values in a block of the target block.
In this embodiment, the partial block chain accounts stored in the slave storage node 41, the slave storage node 42, and the slave storage node 43 may be the same or different, and for example, alternatively, the P-th block is stored in the slave storage node 41, the P + 1-th block is stored in the slave storage node 42, and the P + 2-th block is stored in the slave storage node 43. This is merely an illustrative example, and does not limit the number of blocks stored in each slave storage node.
Optionally, the master storage node 31 sends a second query request to the slave storage node 41 to query and obtain a certain transaction information in the pth block or a value of a certain field in the block body of the pth block.
The master storage node 31 sends a second query request to the slave storage node 42 to query for a certain transaction information in the P +1 th block or a value of a certain field in the block of the P +1 th block.
The master storage node 31 sends a second query request to the slave storage node 43 to query for a certain transaction information in the P +2 th block or a value of a certain field in the block body of the P +2 th block.
Accordingly, the main storage node 31 receives a certain transaction information in the block of the P-th block or a certain field value in the block of the P-th block fed back from the storage node 41.
The main storage node 31 receives a certain transaction information in the P +1 th block or a certain field value in the block body of the P +1 th block fed back from the storage node 42.
The main storage node 31 receives a certain transaction information in the P +2 th block or a certain field value in the block body of the P +2 th block fed back from the storage node 43.
And step 403, the master storage node determines the reliability of each slave storage node by comparing the query result fed back by each slave storage node with the block chain ledger stored in the master storage node.
Since the main storage node 31 locally stores a complete blockchain account book, the main storage node 31 may compare whether a certain transaction information in the P-th block fed back from the storage node 41 is consistent with a certain transaction information in the locally stored P-th block, or the main storage node 31 may compare whether a value of a certain field in the block body of the P-th block fed back from the storage node 41 is consistent with a value of a certain field in the block body of the locally stored P-th block, and if so, the main storage node 31 may correspondingly increase the reliability of the slave storage node 41.
Similarly, the master storage node 31 adjusts the reliability of the slave storage node 42 by comparing whether the partial content of the P +1 th block fed back from the slave storage node 42 is consistent with the partial content of the P +1 th block stored locally; and the main storage node 31 adjusts the reliability of the slave storage node 43 by comparing whether the partial content of the P +2 th chunk fed back from the slave storage node 43 is consistent with the partial content of the P +2 th chunk stored locally.
And 404, the master storage node sorts the identification information of the plurality of locally stored slave storage nodes according to the reliability of each slave storage node.
Optionally, the master storage node locally stores a list including identification information and reliability of slave storage nodes communicatively connected to the master storage node, for example, the master storage node 31 locally stores a list including identification information and reliability of the slave storage node 41, identification information and reliability of the slave storage node 42, identification information and reliability of the slave storage node 43, and optionally, identification information and reliability of each slave storage node is an entry of the list.
After the master storage node 31 adjusts the reliabilities of the slave storage node 41, the slave storage node 42, and the slave storage node 43, respectively, each entry in the locally stored list may be reordered according to the adjusted reliabilities of the slave storage node 41, the slave storage node 42, and the slave storage node 43. For example, the master storage node 31 reorders each entry in the list in order of high to low reliability.
The embodiment of the invention sends a query request to a plurality of slave storage nodes through a master storage node to query and acquire the partial content of the target block stored by each slave storage node, and further determines the reliability of each slave storage node by comparing the partial content of the target block fed back by each slave storage node with the partial content of the target block stored in the master storage node, so that when a block generation node generates a new block, the new block is sent to a slave storage node with higher reliability, thereby improving the reliability of a block chain account book.
