The present invention will be described in further detail with reference to examples.
Fig. 1 is a schematic flowchart of an information processing method according to an embodiment of the present invention; the method can be applied to a first node in a block chain network, and the first node can be any Peer node in the block chain network; as shown in fig. 1, the method includes:
Specifically, before step 101, the method further includes:
receiving a transaction request sent by a terminal, carrying out transaction endorsement according to the transaction request, and sending a transaction endorsement result to the terminal. Here, the first node may perform transaction endorsement as an endorsement node.
It should be noted that the transaction endorsement may also be performed by other nodes in the blockchain network, i.e. the first node no longer acts as an endorsement node.
Specifically, some embodiments provide an information processing method that can be applied to a transaction flow between an Application program (APP) and a blockchain network. Transaction endorsements are typically performed prior to performing step 101. The transaction endorsement process comprises the following steps: the method comprises the steps that a user creates a transaction through an Application program (APP) on a terminal of the user, the APP determines a transaction request according to the created transaction, and sends the transaction request to a chosen endorsement node of the user, and in some embodiments, the endorsement node can be any Peer node in a block chain network, such as the first node. The endorsement node simulates transaction to generate an endorsement signature, namely, the endorsement transaction is carried out; and after the transaction endorsement is completed, the endorsement node sends a transaction endorsement result to the APP. After determining a transaction endorsement result, the APP can send a transaction consensus request to a consensus node, and the consensus node receives the transaction consensus request sent by the APP and generates a block according to the transaction consensus request; sending a block broadcast message according to the generated block, wherein the block broadcast message is used for informing the generated block; after receiving the block broadcast message, the first node sends a block request message to the common node according to the block broadcast message, that is, the first node executes step 101.
Here, the endorsement node simulates a transaction, i.e. the endorsement node attempts to execute the transaction, specifically, the endorsement node executes the name and parameters of the chain code to be executed in the transaction, and the simulated transaction is essentially the chain code specified in the simulated execution transaction. Endorsement signatures can be generated by endorsement of state changes (recorded in a read-write set, and the record content can include a read state key and version, and a written state key value) caused by transactions.
It should be noted that, when the first node receives a block broadcast message sent by a consensus node and sends a block request message to the consensus node according to the block broadcast message, the identity of the first node is an accounting node, and is used to maintain structures (including a world state table, a history index table, and a block index table) of a block chain and a super account book.
Here, the functions of the respective nodes in the block chain network are further explained as follows.
APP: the terminal interacts with the blockchain network based on the downloaded and installed APP. Before initiating a formal transaction, a transaction (promosal) needs to be created and submitted to an endorsement node for endorsement; after the APP collects enough endorsement support (the specific number is determined according to the endorsement strategy), a legal transaction request (endorsement with an endorsement node) can be constructed by using the endorsement and sent to the consensus node; and generating a block corresponding to the transaction request by the consensus node according to the transaction request.
Endorsement node (Endorser): the method is mainly used for calling the APP to complete endorsement processing of a transaction proposal. After receiving a transaction proposal from the APP, checking validity, authority and the like, simulating the transaction if the check is passed, endorseing the state change caused by the transaction, and generating an endorsement signature; and returning a transaction endorsement result to the APP after the transaction is simulated, wherein the transaction endorsement result comprises the generated endorsement signature.
Consensus node (Orderer): and receiving the transaction containing the endorsement signature, sequencing the received transactions and generating a block, wherein the generated block is used for broadcasting to the Peer node.
Accounting node (commit): and maintaining the structures of the block chain and the account book.
102, receiving a block response message sent by the consensus node for the block request message, and executing a first synchronization operation according to the block response message; wherein the first synchronization operation comprises at least one of: and synchronizing the blocks, updating the world state table, updating the history index table and updating the block index table according to the block response message.
In this embodiment, the first node stores a world state table, a history index table, and a block index table.
Here, the world state table, also referred to as a state DataBase (DB, DataBase), records a correspondence relationship between the latest value of each block after the execution of the transaction and the key of the block.
Accordingly, the updating the world state table comprises: and updating the latest world state, namely updating the latest value of each block.
The history index table, also called history DB, is used to record the correspondence between the history operation executed for any transaction in any block and the corresponding key of the block and the transaction key.
Correspondingly, the updating the history index table comprises the following steps: historical index records are added for the block response message synchronization block and for transactions in the block.
The block index table, also called index DB, is used to record the correspondence between the storage location where the block is located and the key of the block.
Correspondingly, the updating the block index table includes: adding a block index record; the block index record comprises: the key of the block and the storage location of the block (e.g., a node in the chain network of blocks where the block resides).
Generally, the key of the transaction may be the name of the transaction. The key of the tile may be the filename (nFile) and/or the tile name (nBlockPos) of the tile. That is, according to nFile and/or nbockpos, the corresponding table is searched, and the latest value, the storage location where the block is located, and the like can be determined. Furthermore, in the block index table, for each block, two pointer keys may be recorded, which correspond to the previous and next blocks of the block, respectively, so that the entire block chain may be determined according to the block index table.
In this embodiment, the synchronization block includes: and verifying the block corresponding to the block response message (such as verifying the transaction message structure, the signature integrity, whether the read-write set versions are repeated, whether the read-write set versions are matched and the like). After the verification is passed, the world state table, the history index table and the block index table can be updated.
In this embodiment, the method further includes:
sending an event monitoring response message to the terminal to inform the terminal of an event processing result; the event processing result comprises at least one of the following: a block request message has been sent to the consensus node that a first synchronization operation has been performed.
Here, before the sending the event listening response message to the terminal, the method further includes: and determining whether the terminal is configured with an event monitoring request.
Specifically, the terminal has a human-computer interaction interface, and a user can operate the APP through the human-computer interaction interface, where the operation includes the above-mentioned creation transaction, and may also include a configuration event monitoring request; for example, when a transaction is created, the APP may provide an event monitoring request button, and when a user clicks the event monitoring request button, the APP may determine a corresponding event monitoring instruction.
In an embodiment, the event monitoring instruction may be carried in the transaction request and sent to the first node, so that the first node determines whether the terminal is configured with the event monitoring request according to whether the event monitoring instruction is received.
In another embodiment, the first node may send a confirmation request to the terminal to confirm whether the terminal is configured with an event monitoring request; after receiving the confirmation request, the terminal determines whether the terminal is configured with an event monitoring request, and replies a confirmation message if the terminal is configured with the event monitoring request; and if the terminal is determined not to be configured with the event monitoring request, replying a denial message.
In this embodiment, the method further includes:
receiving an inquiry request sent by a terminal;
inquiring the world state table according to the inquiry request;
determining the latest value of a first target block corresponding to the query request;
and sending the determined latest value of the first target block to a terminal.
Here, when the query request is a query request for a first target block, the latest value of the first target block includes: a latest value of at least one transaction in the first target block.
When the query request is a query request for a transaction in a first target block, the latest value of the first target block specifically refers to: the latest value for a transaction in the first target block.
In this embodiment, the method further includes:
receiving a first acquisition request sent by a terminal;
inquiring the block index table according to the first acquisition request, and determining a first target node where a second target block corresponding to the first acquisition request is located; the first target node stores at least one block;
sending a second acquisition request to the determined first target node, and receiving a data block of a second target block sent by the first target node aiming at the second acquisition request;
and sending the data block of the second target block to the terminal.
Here, the second acquisition request is generated by the first node, and the second acquisition request should include at least an identification of the second target block. And sending a second acquisition request to inform the first target node of requesting to acquire the data block of the second target block corresponding to the identifier.
In this embodiment, the method further includes:
receiving a third acquisition request sent by the terminal;
inquiring the historical index table according to the third acquisition request, and determining a third target block where a target transaction place corresponding to the third acquisition request is located and a second target node where the third target block is located; the second target node stores at least one block;
sending a fourth acquisition request to the second target node, and receiving a target historical operation record of a target transaction sent by the second target node aiming at the fourth acquisition request;
and sending the target historical operation record of the target transaction to the terminal.
Here, the fourth obtaining request is generated by the first node, and the second obtaining request should at least include an identifier of the third target block and an identifier of the target historical operation record, so as to inform the second target node of the request for obtaining the target historical operation record in the third target block.
The sending to the terminal specifically refers to the APP sent to the terminal.
Here, the query request, the first obtaining request, and the third obtaining request sent by the receiving terminal specifically refer to the query request, the first obtaining request, and the third obtaining request sent by the APP of the receiving terminal.
In this embodiment, the blockchain network may include a first node and a second node, where the second node is different from the first node, and the second node stores ledger data including at least one block in addition to a world state table, a history index table, and a block index table; further, it is understood that the second node holds at least one block, and the block includes related data of the block, such as a data block (including a history record), block header information of the data block, and the like.
The first target node where the first target block is located and the second target node where the second target block is located may be any second node in the block chain network.
The number of the first nodes and the number of the second nodes allocated in the blockchain network are determined by a developer, and the allocation may be performed based on how many resources of the blockchain network are, specifically, when the resources are more, the number of the second nodes may be relatively more, and when the resources are less, the number of the second nodes may be relatively less, but it should be noted that at least one second node is included in the blockchain network.
The following description is made for the consensus node, and the information processing method applied to the consensus node includes:
receiving transaction information sent by a terminal, and generating a block according to the transaction information;
receiving a block request message transmitted by a node (here, the first node or the second node) according to the generated block transmission block broadcast message;
sending a block response message according to the block request message, wherein the block response message is received by the node and executes synchronous operation; when the node is a first node, executing a first processing operation, and when the node is a second node, executing a second processing operation;
wherein the first processing operation comprises at least one of: synchronizing the blocks according to the block response message, updating a world state table according to the synchronized blocks, updating a history index table according to the synchronized blocks, and updating a block index table according to the synchronized blocks;

It can be seen that the operations performed by the first node and the second node are different, and the first node does not need to write the block into the book data, so that resource consumption of the node is reduced, and for the whole blockchain network, resource consumption in the blockchain network is also reduced.
It should be noted that the blockchain network must include at least one second node and may also include at least one first node. The number of the first nodes and the second nodes is determined according to the number of resources of the block chain network; when the resources are more, developers can set more second nodes, and when the resources are less, the developers can set more first nodes on the basis of ensuring at least one second node.
Fig. 2 is a schematic diagram illustrating a comparison between a first node and a second node according to an embodiment of the present invention; as shown in fig. 2, the right side is a lightweight node, and the lightweight node only stores a world state table, a history index table, and a block index table. When the lightweight node needs to query historical data (such as specific data for a certain transaction), the lightweight node can be queried in a full-scale mode.
And the left side of the system is provided with a full-scale node, and the full-scale node is stored with account book data besides a world state table, a history index table and a block index table. Here, the book data stores, in addition to the real data blocks: chain information for each node in the blockchain, block header information for the data block, a signature for each transaction, a certificate, etc.
The full-magnitude node may serve as the second node in the method shown in fig. 1, and the lightweight node may serve as the first node in the method shown in fig. 1.
FIG. 3 is a flow chart illustrating another information processing method according to an embodiment of the present invention; as shown in fig. 3, the method includes:
step 301, the APP submits the transaction to the lightweight node.
And step 302, the lightweight node carries out transaction endorsement according to the submitted transaction, and returns an endorsement result to the APP after the transaction endorsement is completed.
And step 303, the APP sends the endorsement result to a consensus node for consensus.
Specifically, the APP sends a transaction consensus request to the consensus node, the transaction consensus request including the endorsement result.
Step 304, the consensus node generates a block according to the transaction consensus request, and broadcasts new block information in the blockchain network.
Step 305, after receiving the broadcast, each relevant node sends a block request message to the common node to request block information.
Step 306, the consensus node replies to the block response message, and each relevant node performs a corresponding operation according to the block response message.
In particular, the related nodes include: a lightweight node (which may be understood as a first node in the method shown in fig. 1) and a full-scale node (which may be understood as a second node in the method shown in fig. 1).
For a full-scale node, step 3061 is performed: after the block is synchronized, the new block is written into the local chain (i.e. the new block is written into the account book data), and then the local world state table, the historical index table and the account book index table are updated.
For lightweight nodes, step 3062 is performed: and a local account book does not need to be written, and only the local world state table, the historical index table and the account book index table need to be updated.
It can be seen that the above steps are the steps when the front blockchain is from sending a transaction to writing a block, with the difference that the processing is different for the full-weight node than for the lightweight node for the block taken.
It should be noted that, in the above method, after receiving the broadcast new block information, the lightweight node may send an event monitoring response to the APP. Specifically, reference may be made to the method in fig. 1, which is not described herein for further details.
