Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
FIG. 1 is a diagram of an implementation environment of a blockchain real-time storage method provided in one embodiment, as shown in FIG. 1, in which a plurality of blockchain nodes 100 included in a blockchain network are included
The blockchain nodes 100 constitute a blockchain network for server nodes using the various unit departments of the blockchain system. When the blockchain node 100 generates data change, the changed data is cached, then the cached data is packaged to generate a new block, and after the cached data is generated into the block, the block is synchronized to all nodes in the blockchain network. Because the blockchain node 100 has cached the data prior to the process of generating and synchronizing the data to the blockchain network, the blockchain node 100 may use the data prior to synchronizing the data to the blockchain network when conducting data transactions with other nodes in the blockchain network.
It should be noted that the blockchain node 100 may be, but is not limited to, a desktop server, a mainframe server, a cloud server, a server cluster, and various terminal servers. The blockchain nodes 100 may be connected by a wired, wireless or other communication connection, which is not limited in this disclosure.
As shown in fig. 2, in one embodiment, a blockchain real-time storage method is provided, and the blockchain real-time storage method may be applied to the blockchain node 100, and specifically may include the following steps:
step S100, responding to the data change of a first node in a blockchain network, and caching the changed data so that the data is used by the first node before the blockchain synchronization is completed;
it should be appreciated that the first node or other blockchain node in the method may be any blockchain node 100 in fig. 1.
The scheme mainly aims at solving the problem of high delay in the blockchain network by adding a buffer module in the nodes of the blockchain for buffering data. When the data of the block chain node changes, the changed data is cached through the cache module of the node so as to be used before the data synchronization is completed in the block chain, so that even if the newly changed data in the block chain link point is not synchronized to the block chain network, the cached data can be used for data processing to interact with other nodes, the waiting time for the changed data to be synchronized to the block chain network is not needed, the waiting time is shortened, the problem of high delay of the block chain is solved, the time of a user is saved, and the user experience is improved.
Step S200, generating a block from the data buffered by the first node;
after the data is cached in the corresponding caching module, the cached data can be uplink and synchronized to the blockchain network, and the data to be synchronized is required to be processed in the synchronization process to generate the block. After the data is cached, the changed data is conveniently used before the data is synchronized in the blockchain, and the data is generated into blocks in real time so as to be synchronized into the blockchain network, so that the risk of tampering caused by untimely synchronization of the data after the data is cached can be avoided, and the safety of the data is improved.
Step S300, synchronizing the block to other blockchain nodes in the blockchain network, except the first node.
After the block is generated, the data may be synchronized to other nodes in the blockchain network. At this time, the corresponding data is still cached in the cache node, so that the first node can still be used for the first node, and the first node does not need to wait for the synchronous completion of the blockchain when processing the locally generated data, thereby greatly improving the user experience.
In one embodiment, the first node is a server node in a unit, and when the server node in the unit performs data interaction with another department server node in a same blockchain network, a large amount of data is generated, and at this time, the server node in the unit and the other department server node each buffer data generated by the respective node in a buffer module of the respective node, and when performing data processing, the data in the buffer module of the respective node is directly used for performing data processing. And meanwhile, after the data is cached to the node module, the cached data is synchronized to the blockchain network in real time, so that the risk that the cached data is tampered is avoided, and the safety of the data in the use process of the system is improved.
FIG. 3 illustrates that in one embodiment, following step S300 in the corresponding embodiment of FIG. 2, the blockchain real-time storage method may further include the steps of:
step S400, clearing all the data that have been synchronously completed in the data cached by the first node.
After the data synchronization is completed, the data can be used by the first node even if the data is not cached, and the cached data can be cleared at this time to maximally utilize the cached space, otherwise, after the data caching space is used, other newly generated data cannot be cached continuously.
FIG. 4 illustrates that in one embodiment, following step S100 in the corresponding embodiment of FIG. 2, the blockchain real-time storage method may further include the steps of:
step S101, responding to a data calling request of a first node, and calling changed data cached by the first node.
For example, in one embodiment, a customer conducts a transaction with his own terminal and a banking server, both of which are nodes in a blockchain network. In the transaction process, the client terminal and the bank server can generate a large amount of data, at the moment, the client terminal and the bank server respectively cache the received and generated data to respective cache nodes for caching, and in the transaction process, the data in the cache nodes can be directly called for use if the newly generated data are needed, and the data can be used after the block link points are used after the synchronization of the data is completed.
Optionally, fig. 5 is a detailed description of step S100 in the blockchain real-time storage method according to the corresponding embodiment of fig. 2, where there are a plurality of cache modules of the first node, step S100 may include the following steps:
step S110, responding to the data change of a first node in a blockchain network, and inquiring the cache load of each cache module of the blockchain first node;
step S120, selecting a cache module for data caching according to the cache load of each cache module of the first node of the blockchain.
The buffer load may be the remaining buffer capacity and the buffered capacity of each buffer module, and the selecting method may be to select a buffer module with the smallest buffer load as a buffer module for data, or select one of nodes meeting a predetermined threshold as a module for data buffer. The predetermined storage threshold is, for example, 215KB, 345MB, 46GB, etc., which is not limited herein.
In one embodiment, the buffer load is the buffered capacity of the buffer module, after the first node of the blockchain changes, the buffered capacity of each buffer module of the first node of the blockchain is queried first, and then the buffer module with the minimum buffered capacity is selected as the module for data buffering.
In another embodiment, the buffer load is a remaining buffer capacity of the buffer module, after the first node of the blockchain changes, the remaining buffer capacity of each buffer module of the first node of the blockchain is queried first, then whether the remaining buffer capacity of each buffer module exceeds a predetermined remaining storage threshold value is judged, if the remaining buffer capacity exceeds the predetermined remaining storage threshold value, then a buffer module with the largest stored capacity among the buffer modules with the remaining buffer capacity exceeding the predetermined remaining storage threshold value is selected.
In this embodiment, the predetermined remaining storage threshold is the size of the data to be cached, so that in the use process, the storage space of each cache module can be utilized to the maximum extent, when the storage space of a certain cache module is used, the cached data is directly and synchronously completed, and after all the cached data are synchronously completed, the cached data are timely emptied. Therefore, the situation that the data cannot be emptied in time due to the fact that a large amount of data are generated in the transaction process, but the data cached by each cache module in the blockchain node are not synchronously completed, and therefore the situation of data congestion occurs can be avoided.
Optionally, fig. 6 is a detailed description of step S200 in the blockchain real-time storage method according to the corresponding embodiment of fig. 2, where step S200 may include the following steps:
step S210, encrypting the data cached by the first node;
step S220, packaging the encrypted data to generate a block.
In the scheme, when generating the block, the data to be synchronized needs to be encrypted first, and then the encryption processing is completed and then the packaging processing is carried out, then a block is generated, and then the block can be synchronized. The encryption method is that, for example, the data cached by the first node is randomly divided into a plurality of parts, a character string of the splicing sequence of the data fragments is generated, and then the character string is encrypted through a hash algorithm. The encryption method may also be to directly perform asymmetric encryption on the data. The encryption method can also be to directly encrypt the data randomly and dynamically.
Optionally, fig. 7 is a detailed description of step S210 in the blockchain real-time storage method according to the corresponding embodiment of fig. 6, where step S210 may include the following steps:
step S211, creating a cryptographic module in the first node;
and step S212, the data cached by the first node are stored in the cryptographic module in a sealing mode, so that the data cached by the first node are synchronized to other nodes in the blockchain network except the first node after being packaged along with the cryptographic module.
In the scheme, the encryption mode is to newly establish a cryptographic module in the storage area, and seal the data cached by the first node in the cryptographic module so as to isolate the connection between the data cached by the first node and the outside. The password module has a strict boundary to block the connection between the outside and the inside, if the data cached by the first node in the password module is required to be read, the data cached by the first node can only be read through a specific interface, and the safety of the data cached by the first node is ensured. When the data stored in the first node is stored in the cryptographic module, the data is synchronized with the cryptographic module to all nodes of the blockchain, all the nodes of the blockchain acquire the cryptographic module with a strict boundary, and the data stored in the cryptographic module is verified through a specific interface in the cryptographic module when the data is required to be acquired.
Optionally, fig. 8 is a detailed description of step S212 in the blockchain real-time storage method according to the corresponding embodiment of fig. 7, where step S212 may further include the following steps:
step S2121, splitting the data cached by the first node into cache sub-data with the same number as the number of the password modules;
step S2122, storing the cache sub-data in different cipher modules in a one-to-one correspondence manner, wherein each cipher module stores only one cache sub-data;
step S2123, generating a storage sequence of the cached sub-data, dynamically encrypting the storage sequence, and storing the first node.
In the scheme, when the password modules are created in the first node, a plurality of password modules are created, then the data cached in the first node are split into cache sub-data with the same number as the password modules according to the number of the password modules, then each password module stores one cache sub-data, if the complete data cached in the first node are required to be obtained, the data are required to be read from all the password modules, all the cache sub-data are obtained, and the cache sub-data are spliced in sequence, so that the complete data cached in the first node can be obtained, and the safety of the data storage of the first node is improved.
In one embodiment of the present invention, the dynamic encryption method first needs to acquire the storage sequence and store the storage sequence data so as to process the storage sequence data conveniently, where the storage sequence data may be regarded as a string of character strings stored in a local device. After the storage sequence character strings needing to be encrypted are acquired and stored, carrying out specified abstract operation on the specified characteristic information of the storage sequence, and determining the initial character for encrypting the storage sequence according to the result of the specified abstract operation. And then starting from the initial character, acquiring an encryption key from the storage sequence character string. And then encrypting the storage sequence character string by using the encryption key according to a preset encryption algorithm, wherein the preset algorithm is an algorithm for generating the encryption key. And finally, after encryption is finished, the encrypted storage data character string can be sent to other nodes of the blockchain network.
In this embodiment, the specified feature information may be a string length of the storage sequence, or may be a size of the storage sequence in other embodiments.
The method of the digest operation is, for example, hash operation, random operation, etc., and in this embodiment, the method of the digest operation is calculation by the following formula
B＝L mod rand(0，[lnL])
Wherein B is the result of the digest operation, L is the string length of the storage sequence, mod is the remainder function, rand (x, y) is the random function with the definition domain from x to y, x is the rounding function, and ln is the natural logarithm function. The formula can ensure the randomness of the abstract operation result through a random function so as to ensure that the encrypted abstract operation result is not easy to crack, improve the encryption safety, and ensure that the obtained result is not too large through the cooperation of a natural logarithmic function and a rounding function so as to ensure the safety of the subsequent encryption process.
In this embodiment, the method for encrypting the storage sequence string is to extract the storage sequence string from the initial character every predetermined number of bits to a predetermined length, where the predetermined number of bits may be 1 bit, 2 bits, a prime number, etc., and the predetermined length may be the length of the storage sequence string, or may be 20 bits or 304 bits, and the predetermined number of bits and the predetermined length may be set according to specific situations, and the scheme is not limited.
