Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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 application.
On the premise of meeting the inquiry requirement of account state data, how to reduce the consumption of storage resources becomes an urgent technical problem to be solved. Therefore, the embodiment of the application provides a method, a device, equipment and a medium for creating a service filing node and processing data. In the embodiment of the application, a novel business filing node can be created in the blockchain network, so that the inquiry requirements of some business scenes on account state data of each blockchain account can be met, and the consumption of storage resources caused by the use of the filing node can be greatly reduced and the storage cost is reduced because the business filing node is a lightweight filing node.
First, some terms related to embodiments of the present application are described:
a blockchain account: uniquely identifying the identity of the user in the blockchain network. Taking etherhouses as an example, the blockchain accounts can be divided into external accounts (external owned accounts) and contract accounts (contract accounts). The account status information of the external account includes, for example, but is not limited to: account identification (also known as account address), balance, and random number (nounce). The account status information of a contract account includes, for example, but is not limited to: account identification, balance, random number (nounce), code, and stub of the smart contract, etc.
And (3) a service filing node: refers to a block link node having a data storage capacity greater than a full node but less than an archive node. In the embodiment of the application, the business filing node additionally stores account state information of the blockchain account related to the business demand at each block height according to the business demand relative to the whole node. Compared with the filing node, the business filing node is a lightweight filing node, and on the premise of meeting the inquiry requirement of account state data required by business requirements, the consumption of storage resources is reduced, and the storage cost is reduced.
Block height: the sequence number of the chunk added to the blockchain may be used as a unique identifier of the chunk, indicating the location of the chunk in the blockchain, and the height of the chunk starts from 0, for example. The current block height refers to the sequence number of a new block currently added to the block chain; the historical block height refers to the sequence number of the existing block which is added into the block chain earlier than the new block, that is, the appearance time of the historical block height is earlier than the current block height.
And (3) state tree: for a state tree, each node basically comprises a key value mapping, wherein the keys are blockchain accounts, and the values are account state information including account statement, balance, random number notice, code, storage root and the like.
P2P (Peer-to-Peer networking) network: also known as Peer-to-Peer networks, or Peer-to-Peer networks, the participants of the network share a portion of the hardware resources (such as processing power, storage power, network connectivity, printers, etc.) they own, and these shared resources provide services and content over the network and can be accessed directly by other Peer nodes (peers) without going through intermediate entities.
Smart contract (Smart contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Smart contracts allow trusted transactions, which are traceable and irreversible, to be conducted without a third party. Essentially, the working principle of these automatic contracts is similar to if-then statements of other computer programs. Smart contracts interact with real-world assets only in this manner. When a pre-programmed condition is triggered, the intelligent contract executes the corresponding contract clause.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is an architecture diagram of a blockchain network provided in the present application. As shown in fig. 1, the blockchain network may include a plurality of blockchain nodes, each of which collectively form a blockchain network, which is a P2P network. The block chain link points can be terminal equipment or servers, the positions of the block chain nodes in the block chain network are equal, and the block chain link points maintain a block chain together.
In this embodiment of the present application, the type of the Block chain network is not limited, and may be, for example, a Public Block chain (Public Block Chains), a Private Block chain (Private Block Chains), a federation Block chain, a permission Block chain, and the like. The public block chain has the characteristic of public deployment, and any person can participate randomly; the private block chain has the characteristic of private deployment and is limited to be used in a certain organization; the block chain of alliance and the block chain of permission have the characteristic of private deployment, and multiple organizations use together and have admission and authority management mechanisms.
In the embodiments of the present application, the blockchain network includes, for example, but not limited to: an ethernet network.
The terminal device may be hardware or software. When the terminal device is hardware, the terminal device is, for example, a mobile phone, a tablet computer, a desktop computer, a wearable smart device, a smart home device, or the like. When the terminal device is software, it may be installed in the above listed hardware devices, in this case, the terminal device is, for example, a plurality of software modules or a single software module, and the embodiments of the present application are not limited. The server may be hardware or software. When the server is hardware, the server is a single server or a distributed server cluster composed of a plurality of servers. When the server is software, the server may be a plurality of software modules or a single software module, and the embodiments of the present application are not limited.
It should be understood that the block link points in fig. 1 are merely schematic. In practical application, any number of block link points are deployed according to actual requirements.
Fig. 2 is a flowchart of a method for creating a service archive node according to an embodiment of the present application. The method may be performed by a traffic archive node creation means, which may be implemented in software and/or hardware, and may typically be integrated in a block chaining point. As shown in fig. 2, the method may include the steps of:
201. determining at least one first blockchain account which is associated with the service requirement from all blockchain accounts on the blockchain network; any blockchain node in the control blockchain network repeats steps 202-203 so that a blockchain link node is created as a traffic archive node.
202. In response to the current block height of the blockchain, account status information of each of the at least one first blockchain account at the current block height is obtained.
203. And storing the account state information of each of the at least one first blockchain account under the current blockheight into a database.
In the embodiment of the present application, different blockchain accounts are required for different business requirements, and for this purpose, at least one blockchain account associated with a business requirement is determined from all blockchain accounts on a blockchain network, and the at least one blockchain account associated with the business requirement is determined as at least one first blockchain account. Wherein, the number of the first block chain accounts can be one or more.
In this embodiment, any blockchain node may be selected from the blockchain network for function expansion, so that the blockchain node becomes a service archive node. In practical application, one blockchain node can be randomly selected from each blockchain node for function expansion. One of the block link nodes having good resource use, good load, or good communication quality may be selected from each of the block link nodes according to the resource use, the load, or the communication quality of each of the block link nodes, and the function may be expanded.
In the specific implementation, for the block chain link points which are selected for function expansion, when the block height of the block chain is updated, that is, a new block is added to the block chain, the account state information of each first block chain account at the current block height is obtained, and the account state information of at least one first block chain account at the current block height is stored in the database, so that the query requirement of the account state data of the block chain account related to the service requirement is met.
According to the technical scheme, the novel business filing node can be established in the blockchain network, the inquiry requirements of some business scenes on account state data of each blockchain account can be met, and the consumption of storage resources caused by the use of the filing node can be greatly reduced due to the fact that the business filing node is a light filing node, and the storage cost is reduced.
In practical applications, in the case that the blockchain is at the current blockheight, if only the account status information of the blockchain account associated with the business requirement at the current blockheight is kept in the database, some business failures may be caused. Thus, further optionally, in order to ensure availability and reliability of the services provided by the blockchain network, the traffic archiving node may further: and responding to the current block height of the block chain, acquiring the account state information of each second block chain account under the current block height, wherein the second block chain account is not related to the service requirement, and storing the account state information of each second block chain account under the current block height in a database.
It should be noted that, in the case that the blockchain is at the current blockheight, although the account status information of all blockchain accounts at the current blockheight is simultaneously stored in the database, the account status information of blockchain accounts not related to the business requirement at the current blockheight is only temporarily stored in the database, and is then deleted from the database as appropriate.
Thus, as a further alternative, the service archiving node may further select, in response to the current block height of the block chain, a target historical block height that meets a preset archiving threshold condition with the current block height from among historical block heights occurring earlier than the current block height on the block chain; and deleting the account state information of each second blockchain account which is saved in the database and is at the height of the target historical block.
In this embodiment, the predetermined archive threshold condition is determined according to actual conditions, for example, the number of blocks is 5 or 8. For example, if the predetermined archiving threshold condition is the number of M blocks, M is a positive integer. And when the current block height on the block chain is N + M, deleting the account state information of at least one second block chain account which is already stored in the database under the block height N on the block chain, wherein N is a positive integer.
It should be noted that the deletion time of the account status information of the second blockchain account at the target historical block height in the database is constrained by using the preset archive threshold condition, so as to ensure the stability of blockchain generation.
In practice, although the second blockchain account is determined according to whether the second blockchain account is related to the service requirement, due to the complexity of the blockchain network, account status information of the second blockchain account may be required in the blockchain generation process. Thus, it is further optional to accurately identify in conjunction with the status tree whether account status information for a second blockchain account in the database can be deleted to further ensure availability and reliability of services provided by the blockchain network. Specifically, an alternative implementation manner for deleting the account status information of each of the at least one second blockchain account stored in the database at the target historical blockheight is to: for any second blockchain account, judging whether a node corresponding to the second blockchain account in the state tree corresponding to the height of the target historical blockchain is referred by the state tree corresponding to the height of the current blockchain; if not, deleting the account state information of the second block chain account stored in the database under the height of the target historical block; if yes, the account state information of the second block chain account stored in the database under the height of the target historical block is reserved.
Specifically, each tile corresponds to a state tree, and the leaf nodes of the state tree of each tile represent a chain of tiles account. Whether reference relations exist among nodes of different state trees or not can be determined by analyzing node information of the state trees corresponding to the blocks.
Referring to fig. 3, account a is a first blockchain account and account b is a second blockchain account. Taking M as an example, when the currently added block in the block chain is a block N, the account state information of the account b in the database under the block N-1 needs to be deleted originally, but since a node in the state tree of the block N references a node in the state tree of the block N-1, which corresponds to the account b (a connection line exists between corresponding nodes in fig. 3 indicates that there is a reference relationship), the account state information of the account b in the database under the block N-1 does not need to be deleted.
In some embodiments, the service archiving node may further receive an account status information recovery instruction, where the account status information recovery instruction is used to instruct the database to recover the account status information of the deleted second blockchain account at each historical block height; responding to the account state information recovery instruction, and sequentially executing the transaction related to the deleted second blockchain account in each block on the blockchain so as to obtain the account state information of the deleted second blockchain account at each historical block height; and the acquired account state information of the deleted second blockchain account at each historical block height is saved in the database again.
In this embodiment, the service archiving node further has a re-archiving capability, so that the account status information of the blockchain account that has been deleted in the database is restored to the database, so as to meet flexible and changeable service requirements, and further ensure availability and reliability of the service provided by the blockchain network.
For example, in the case where the currently added block on the blockchain is block N, the account status information for account b under blocks 1 through N-1 has been deleted from the database. If there is a need to restore the account status information of the account b in the blocks 1 to N-1 in the database, the transaction data recorded in each of the blocks 1 to N-1 may be obtained, and the corresponding transaction data is executed again to obtain the account status information of the account b in the blocks 1 to N-1 again, and the account status information of the account b in the blocks 1 to N-1 is stored in the database, so as to realize the re-filing of the account status information of the account b in the blocks 1 to N-1 in the database.

The method may be performed by a data processing device, which may be implemented in software and/or hardware, and may be generally integrated in block-linked points. As shown in fig. 4, the method may include the steps of:
