Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a diagram of an implementation environment of a real-time blockchain storage method provided in an embodiment, as shown in fig. 1, in the implementation environment, a plurality of blockchain nodes 100 included in a blockchain network

The blockchain nodes 100 are server nodes of each unit department using the blockchain system, and form a blockchain network. When the data change occurs in the block chain node 100, the changed data is firstly 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 block chain network. Since the blockchain node 100 has cached the data prior to the process of blockchain node 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 transacting data with other nodes in the blockchain network.

The blockchain node 100 may be, but is not limited to, a desktop computer server, a mainframe computer server, a cloud server, a server cluster, and various terminal servers. The block link nodes 100 may be connected to each other through wired, wireless or other communication connection methods, which is not limited herein.

As shown in fig. 2, in an embodiment, a method for real-time storage of a blockchain is provided, where the method for real-time storage of a blockchain may be applied to the blockchain node 100, and specifically includes the following steps:

step S100, responding to data change of a first node in a block chain network, caching the changed data so that the data can be used by the first node before the block chain synchronization is completed;

it should be understood that the first node or other blockchain node in the method may be any blockchain node 100 in fig. 1.

According to the scheme, a cache module is added in a node of a block chain to cache data, so that the problem of high delay in a block chain network is solved. The specific mode is that when the data of the blockchain node changes, the changed data is cached through the cache module of the node firstly, so that the changed data is used before the data synchronization is completed in the blockchain, and therefore even if the newly changed data in the blockchain node is not synchronized into the blockchain network, the data can be processed by using the cached data and is interacted with other nodes, the changed data does not need to be processed after being synchronized into the blockchain network, the waiting time is reduced, the problem of high delay of the blockchain is solved, the time of a user is saved, and the use experience of the user is improved.

Step S200, generating a block from the data cached by the first node;

after the data is cached in the corresponding cache module, the cached data uplink can be synchronized to the block chain network, and the data to be synchronized needs 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 synchronization is completed in the block chain, and the data is generated into the block in real time so as to be synchronized into the block chain network, so that the risk of tampering caused by untimely synchronization 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 tiles are generated, the data can be synchronized to other nodes in the blockchain network. At this moment, the cache node still caches the corresponding data, so the cache node can still be used by the first node, and the first node does not need to wait for the completion of block chain synchronization when processing locally generated data, thereby greatly improving the user experience.

In one embodiment, the first node is a server node inside a unit, and when the server node inside the unit performs data interaction with another department server node in a block chain network at the same place, a large amount of data is generated, at this time, the server node inside the unit and the another department server node both cache data generated by the respective node in a cache module of the respective node, and directly use the data in the cache module of the respective node for data processing during data processing. Meanwhile, after the data is cached to the node module, the cached data is synchronized to the block chain network in real time, so that the risk that the cached data is tampered is avoided, and the safety of the data in the using process of the system is improved.

Fig. 3 shows that, in an embodiment, after step S300 in the corresponding embodiment of fig. 2, the block chain real-time storage method may further include the following steps:

step S400, clearing all synchronized data in the data cached by the first node.

After the data synchronization is completed, the data can be used by the first node even though the data is not cached, and at this time, the cached data can be cleared to utilize the cached space to the maximum extent, otherwise, when the data caching space is used up, other newly generated data cannot be cached continuously.

Fig. 4 shows that, in an embodiment, after step S100 in the corresponding embodiment of fig. 2, the block chain real-time storage method may further include the following steps:

step S101, responding to a data calling request of a first node, calling the changed data cached by the first node.

For example, in one embodiment, a customer conducts a transaction with a bank server through their own terminal, and the customer's terminal and the bank's server are each a node in a blockchain network. During the transaction process, if the newly generated data are needed to be used, the data in the cache nodes can be directly called for use, and the user terminal and the bank server do not need to wait until the block link point completes the data synchronization and then use the data.

Optionally, fig. 5 is a detailed description of step S100 in the block chain real-time storage method shown in the corresponding embodiment of fig. 2, where in the block chain real-time storage method, there are a plurality of cache modules of the first node, and step S100 may include the following steps:

step S110, responding to the data change of a first node in a block chain network, and inquiring the cache load of each cache module of the first node of the block chain;

and step S120, selecting a cache module for data caching according to the cache load of each cache module of the first node of the block chain.

The cache load may be the remaining cache capacity and the cached capacity of each cache module, the selection method may be to select the cache module with the smallest cache load as the cache module for performing data caching, or to select one of the nodes meeting the predetermined threshold as the module for performing data caching, which is not limited herein. The predetermined storage threshold is, for example, 215KB, 345MB, 46GB, etc., which is not limited herein.

In one embodiment, the cache load is a cached capacity of the cache module, and after the first node of the blockchain changes, the cached capacity of each cache module of the first node of the blockchain is queried first, and then the cache module with the smallest cached capacity is selected as the module for data caching.

In another embodiment, the cache load is a remaining cache capacity of the cache module, after the first node of the block chain changes, the remaining cache capacity of each cache module of the first node of the block chain is queried, and then it is determined whether the remaining cache capacity of each cache module exceeds a predetermined remaining storage threshold, and if the remaining cache capacity of each cache module exceeds the predetermined remaining storage threshold, a cache module with the largest storage capacity among the cache modules whose remaining cache capacities exceed the predetermined remaining storage threshold is selected.

In this embodiment, the predetermined remaining storage threshold is the size of the data to be cached, so that the storage space of each cache module can be utilized to the maximum extent in the using process, when the storage space of one cache module is used up, the synchronization of the cached data is directly completed, and after all the cached data are synchronized, the cached data are emptied in time. Therefore, the situation that data congestion occurs because a large amount of data is generated but the data cached by each cache module in the block chain node is not synchronously completed in the transaction process and cannot be cleared in time can be avoided.

Optionally, fig. 6 is a detailed description of step S200 in the block chain real-time storage method shown in the corresponding embodiment of fig. 2, where in the block chain real-time storage method, step S200 may include the following steps:

step S210, encrypting the data cached by the first node;

step S220, packing the encrypted data to generate a block.

In the scheme, when the block is generated, the data to be synchronized needs to be encrypted first, and then the data is packaged after the encryption is completed, and then a block is generated, and then the blocks can be synchronized. For example, the encryption method includes randomly dividing the data cached by the first node into a plurality of parts, generating a string of the data segments in the splicing sequence, and then encrypting the string by a hash algorithm. The encryption method can also be directly asymmetric encryption of the data. The encryption method can also directly carry out random encryption and dynamic encryption on the data.

Optionally, fig. 7 is a detailed description of step S210 in the block chain real-time storage method shown in the corresponding embodiment of fig. 6, where in the block chain real-time storage method, step S210 may include the following steps:

step S211, creating a cryptographic module in the first node;

step S212, the data cached by the first node is encapsulated in the cryptographic module, so that the data cached by the first node is packaged with the cryptographic module and then synchronized to other nodes in the block chain network except the first node.

In the scheme, the encryption mode is to newly establish a cryptographic module in the storage area and store the data cached by the first node in the cryptographic module so as to isolate the contact between the data cached by the first node and the outside. The cryptographic module has a strict boundary to block the external and internal connection, and if the data cached by the first node in the cryptographic module is required to be read, the data can be read only through a specific interface, so that the security of the data cached by the first node is ensured. When the data cached by the first node is sealed in the cryptographic module, the data is synchronized with the cryptographic module into all nodes of the block chain, all the nodes of the block chain acquire the cryptographic module with a strict boundary and the data sealed in the cryptographic module, and the data needs to be 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 block chain real-time storage method shown in the corresponding embodiment of fig. 7, where in the block chain real-time storage method, step S212 may further include the following steps:

step S2121, dividing the data cached by the first node into cache subdata with the same number as that of the password modules;

step S2122, the cache subdata is respectively and correspondingly stored in different cryptographic modules one by one, and each cryptographic module only stores one cache subdata;

step S2123, generating a storage sequence of the cache subdata, dynamically encrypting the storage sequence, and storing the storage sequence in the first node.

According to the scheme, when the cryptographic module is created in the first node, a plurality of cryptographic modules are created, then the data cached in the first node is divided into cache subdata with the same number as the cryptographic modules according to the number of the cryptographic modules, then each cryptographic module stores one cache subdata, if the complete data cached in the first node is to be obtained, the data is read from all the cryptographic modules, all the cache subdata are obtained, and the cache subdata are spliced together in sequence to obtain the complete data cached in the first node, so that the security of data storage cached in the first node is improved.

In one embodiment of the present invention, the dynamic encryption method first needs to acquire and store the storage sequence to facilitate processing of the storage sequence data, and at this time, the storage sequence data may be regarded as a string of character strings to be stored in a local device. After acquiring and storing the storage sequence character string needing to be encrypted, performing specified abstract operation on specified characteristic information of the storage sequence, and determining initial characters for encrypting the storage sequence according to the result of the specified abstract operation. Then, starting from the start character, an encryption key is obtained in the storage sequence string. The stored sequential string is then encrypted using the encryption key according to a predetermined encryption algorithm, i.e., the algorithm that generated the encryption key. And finally, after encryption is finished, the encrypted storage data character string can be sent to other nodes of the block chain network.

In this embodiment, the specific feature information may be a length of a character string of the storage order, and may also be a size of the storage order in other embodiments.

The method of the digest operation is, for example, a hash operation, a random operation, etc., and in this embodiment, the method of the digest operation is calculated by the following formula

B＝L mod rand(0，[lnL])

Wherein, B is the result of the summary operation, L is the string length of the storage sequence, mod is a remainder function, rand (x, y) is a random function whose domain is x to y, [ x ] is a rounding function, and ln is a 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 be cracked, the encryption safety is improved, and the obtained result is not too large through the cooperation of a natural logarithm function and an integer function so as to ensure the safety of the subsequent encryption process.

In this embodiment, the method for encrypting the storage sequence character string is to extract every predetermined number of bits from a starting character to extract a predetermined length to form an encryption key, where the predetermined number of bits may be 1 bit, 2 bits, prime number bits, and the like, the predetermined length may be the length of the storage sequence character 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.
