The log processing method based on the block chain in the embodiment of the present disclosure is applied to the server 101 in fig. 1, and as shown in fig. 3, the log processing method based on the block chain in the embodiment of the present disclosure includes:
s301, receiving a log storage request sent by a terminal device, wherein the log storage request is used for indicating a system operation log to be stored, and the system operation log carries identification information which represents a unique identification of system operation.
It should be noted that, the features of this embodiment that are the same as those of the above embodiment are not described again in this embodiment.
In some embodiments, the identification information includes a system identification of the system being operated, and a user identification. The system identifier is used for distinguishing different systems, and the user identifier is used for distinguishing different users. The same user may have operation logs in multiple systems, and the operation logs in different systems can be isolated through different system identifications.
In the embodiment, the system operation is characterized by combining the system identifier and the user identifier, so that the operation log record of a specific user in a specific system can be queried specifically through the system identifier and the user identifier subsequently.
S302, determining account information corresponding to the identification information, and determining quota requirement information corresponding to the log storage request, wherein the quota requirement information represents a quota required by a system operation log indicated by the log storage request.
The account information refers to block chain wallet account information, and each system accessing the log uplink service corresponds to one block chain wallet account. The account information corresponding to the identification information may be the account information corresponding to the system indicated by the system identifier determined according to the system identifier in the identification information.
Invoking the smart contract to store the system oplog into the blockchain requires spending a certain amount of tokens. The amount required by storing the system operation log can be understood as the number of tokens required to be spent for calling an intelligent contract to store the system operation log into the block chain, and the amount can be estimated and obtained based on the data size of the system operation log, the network congestion condition and other information.
And S303, if the balance information in the account information is determined to meet the limit requirement information, sending the system operation log to a block chain for storage, wherein the system operation log in the block chain is associated with a storage identifier, and the storage identifier is determined according to the identification information and the uplink time of the system operation log, wherein the uplink time represents the time for storing the system operation log into the block chain.
The balance information in the account information can be understood as the current token amount in the blockchain wallet account corresponding to the system, the balance information in the account information meets the information of the limit requirement, and the current token amount in the blockchain wallet account corresponding to the system is not less than the token amount required to be spent for calling the intelligent contract to store the system operation log in the blockchain.
In some embodiments, if it is determined that the balance information in the account information does not satisfy the credit line requirement information, that is, the current number of tokens in the blockchain wallet account corresponding to the system is less than the number of tokens required to be spent for calling an intelligent contract to store the system operation log in the blockchain, the system operation log is transferred to the blockchain wallet account corresponding to the system, so that the system operation log is stored in the blockchain when the balance information in the account information satisfies the credit line requirement information.
Illustratively, the block chain wallet account corresponding to the system is a common account, a contract account is arranged on the server side, and the contract account holds all tokens and can transfer the tokens to the common account.
In this embodiment, when it is determined that the balance information in the account information satisfies the information required by the quota, the system operation log is stored in the block chain, so that storage failure due to insufficient account balance is avoided, and the storage success rate is improved.
In some embodiments, sending the system operation log to the block chain for storage may include the following steps: storing the system operation log to a cache region; and calling the system operation log from the cache region, and sending the called system operation log to the block chain for storage.
For example, the same user may perform multiple operations on the same system at the same time, for example, a deletion operation is performed while a copy operation is performed, and at this time, multiple system operation logs are generated at the same time, and a concurrent log storage request is triggered. When receiving a concurrent log storage request, the server stores each system operation log indicated in the concurrent log storage request into a cache region, and then calls each system operation log from the cache region one by one and sends the system operation logs to a block chain for storage.
In this embodiment, a buffer is introduced to temporarily store each system operation log indicated in the concurrent log storage request, and then each system operation log is stored into the block chain one by one, so as to avoid network congestion caused by directly storing all system operation logs indicated in the concurrent log storage request into the block chain and error reporting caused by concurrently modifying the shared state, thereby implementing concurrency control and improving the storage success rate.
In some embodiments, the system oplogs in the cache have priority information; the method for retrieving the system operation log from the cache region specifically includes the following steps: and calling the system operation log according to the priority information of the system operation log.
The priority information is used for representing the priority, namely the sequence, of the system operation logs in the cache region. When a plurality of system operation logs exist in the cache region, the system operation logs are called in sequence according to the priority of the system operation logs. Illustratively, the higher the priority of the system oplog, the earlier it is called.
In one example, the buffer area uses a blocking queue, and queues each system operation log indicated in the concurrent log storage request on a first-in first-out basis through the blocking queue.
In this embodiment, priority information is introduced to characterize and determine the order in which the system operation logs in the cache region are called, so that each system operation log in the cache region is stored into the block chain in order, and the concurrency control effect is improved.
In some embodiments, the priority information is any one or more of: the system operation log generation method comprises the steps of the system priority corresponding to the system operation log, the user priority corresponding to the system operation log, the priority input by a user, the generation time of the system operation log and the size of the system operation log.
For example, priorities may be set in advance for different systems, and/or different users, and/or different operations, and for each system operation log indicated in multiple log storage requests triggered simultaneously in the cache, the system operation log with the highest system, and/or user, and/or operation priority may be invoked preferentially.
The order of retrieval may be determined based on the generation time of each system operation log in the cache region, and the earlier the generation time of the system operation log is, the earlier the order of retrieval is.
The calling sequence can also be determined according to the size of each system operation log, and the smallest system operation log in the system operation logs indicated in a plurality of log storage requests triggered simultaneously in the cache region is called preferentially.
In this embodiment, the priority information is determined by one or more of the system priority, the user priority, the operation priority, the generation time of the system operation log, and the size of the system operation log, so that each system operation log in the cache region can be stored in the block chain in order, and the concurrency control effect is improved.
In some embodiments, sending the system operation log to the block chain for storage may include the following steps: determining a block chain to be stored according to the block chain information of the block chain; and sending the system operation log indicated by the log storage request to the determined block chain to be stored for storage.
The block chain to be stored refers to a block chain to which a system operation log indicated by the log storage request is to be stored. The system can access a plurality of log uplink services in advance, namely, the system operation log generated by the user in the system can be selectively stored in the block chain. The server firstly determines a block chain to be stored according to the block chain information of the block chain, and then stores the system operation log indicated by the log storage request to the determined block chain to be stored.
In this embodiment, by determining the block chain to be stored first and then storing the system operation log indicated by the log storage request to the determined block chain to be stored, more selectivity and better flexibility can be provided for log storage, which is beneficial to improving the storage success rate.
In some embodiments, the blockchain information is any one or more of: the remaining storable space of the blockchain, the total storage space of the blockchain, the priority of the blockchain.
For example, the block chain with the largest remaining storable space, or the largest total storage space, or the highest priority may be determined as the block chain to be stored.
In this embodiment, the block chain to be stored is determined according to one or more of the remaining storable space of the block chain, the total storage space of the block chain, and the priority of the block chain, which is helpful for determining the block chain that can better meet the storage requirement, and improves the storage success rate.

The response message may also include a cochain time to indicate when the system oplog was successfully stored in the blockchain.
