Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of an upgrade method of a blockchain network according to an exemplary embodiment of the present disclosure, as shown in the embodiment in fig. 1, showing a low-level blockchain network 100, a high-level blockchain network 200, and at least one upgrade end 300, where the low-level blockchain network 100 includes a plurality of low-level nodes 101, the high-level blockchain network 200 includes a plurality of high-level nodes 201, and the upgrade end 300 is a terminal that can be operated by a user, and may be a terminal with a movable location or a non-movable location, such as a mobile phone, a computer, a server, or a gateway. For example, when the upgrade end 300 is connected to one low-level node 101 and one high-level node 201 respectively, the upgrade end 300 may obtain data from the connected low-level node 101, and write the data into the corresponding connected high-level node 201 for storage, thereby completing the upgrade of the nodes.
In an exemplary embodiment, an upgrading method for a blockchain network is provided, where the upgrading method for a blockchain network may be run in any computing device, for example, in a terminal or a server, or in a server cluster or a cloud server, and of course, a person skilled in the art may also run the method of the present invention on other platforms according to needs, and the disclosure is not limited specifically. Referring to fig. 2, the method for upgrading the exemplary blockchain network includes:
step S201, when receiving an upgrade request for a blockchain network, connects a lower-level node of a lower-level blockchain network and an upper-level node of an upper-level blockchain network corresponding to the lower-level node, respectively.
The low-level blockchain network refers to a blockchain network with a lower version, and compared with a high-level blockchain network with a higher version, the blockchain nodes of the low-level blockchain network have a lower operation speed and a smaller storage capacity. In order to increase the operation speed of the blockchain node and expand the operation speed of the blockchain node, the blockchain network needs to be upgraded, so that the blockchain network can operate efficiently.
The low level nodes refer to the block chain link points of the low level block chain network, and the high level nodes refer to the block chain nodes of the high level block chain network. When the blockchain network is upgraded, a low-level node is corresponding to a high-level node to perform data migration, and when the data stored by all the low-level nodes are migrated to the corresponding high-level node to be stored, the upgrading of the blockchain network is completed.
An upgrade request for a blockchain network refers to information for requesting an upgrade to a blockchain network, which in an example may be sent by a user clicking a particular area on the interface, such as a user clicking an "upgrade" button on the interface to send an upgrade request for a blockchain network, and so on. In another example, the upgrade request for the blockchain network may be automatically sent upon detection of an advanced blockchain network. This embodiment is not particularly limited to this.
When an upgrade request for the blockchain network is received, a lower level node of the lower level blockchain and an upper level node of the upper level blockchain network corresponding to the lower level node are connected, respectively, in an example, the lower level node and the upper level node can be connected by wire, such as a bus, a data transmission line or a network cable, and the like. In another example, the connection may be made with the lower level node, the higher level node, and the like wirelessly, such as a wireless local area network, bluetooth, and the like.
In step S202, a data ID list of data created by the lower node is acquired by the lower node.
The data established by the lower node refers to the data established by the lower node and having ownership. Each piece of data is configured with a data ID at the time of creation, and one piece of data corresponds to one data ID, for example: dataID =123456, inner = a, operator = a, action = insert, content = data content 1, and the above-mentioned operation record represents: when the data content 1 is created, the data ID corresponding to the data content 1 is 123456, the data content 1 is owned by the node a, the operation record is executed by the node a, and the executed action is input.
The data ID list is used to store data IDs of all data created by the lower level node, and in an example, when the lower level node detects that new data is created, the data ID corresponding to the new data is stored in the data ID list, so that data omission is avoided.
In step S203, based on the data ID list, an operation record corresponding to each data ID in the data ID list is acquired from the lower node.
In the present exemplary embodiment, the operation record refers to a record of each operation action of the user on the blockchain network, such as modifying data content, creating data, and the like. According to each data ID in the data ID list, the operation record of the data corresponding to the data ID is searched in the low-level node, so that the integrity of the operation record is ensured, and the condition that the operation record is missed is prevented.
Referring to fig. 3, fig. 3 is a schematic flowchart of a step S203 in an upgrading method of a blockchain network according to an exemplary embodiment of the present disclosure, and in the embodiment shown in fig. 3, the step S203, based on the data ID list, acquiring, by the lower level node, an operation record corresponding to each data ID in the data ID list includes:
in step S301, a block and a key corresponding to each data ID in the data ID list are obtained from the lower node.
In the exemplary embodiment, since the block chain network generates a block according to data to be stored and stores the block, and encrypts the block, leakage of data stored in the block is prevented. According to each data ID, searching the block corresponding to the data ID and the key of the data corresponding to the data ID in the lower node, and decrypting the block corresponding to the data ID according to the key of the data corresponding to the data ID.
In step S302, the block corresponding to the data ID is decrypted according to the obtained key, so as to obtain the operation record corresponding to the data ID.
And decrypting the corresponding block according to the acquired key to obtain the operation record stored in the block. The secret key is obtained to decrypt the block to obtain the operation record stored in the block, so that the data loss caused by the fact that the data stored in the block cannot be read due to incompatibility of encryption modes of a high-level block chain network and a low-level block chain network when the block is simply copied is avoided, and the readability of the data is ensured.
Referring to fig. 2, in step S204, each acquired operation record is correspondingly written into the advanced blockchain network for storage.
In this exemplary embodiment, since the obtained operation record includes operation records of other low-level nodes in the low-level blockchain network on data corresponding to the data ID in the data ID list, each operation record needs to be written into a high-level node in the high-level blockchain network corresponding to the operation node of the operation record for storage, so as to ensure the correctness of the data stored in the blockchain network.
In an exemplary embodiment, writing the obtained each operation record into the advanced block chain network correspondingly for storage includes:
acquiring a timestamp of each operation record;
and writing the operation content of each operation record into the node of the advanced block chain network corresponding to the operation node of the operation record for storage according to the sequence of the time stamps of the operation records.
In the present exemplary embodiment, the timestamp refers to a recording time of the block chain when each operation record is recorded, and continuity of the stored data is guaranteed according to a sequence of the timestamps in the block chain network to form the block chain. And writing each operation record into a high-level node of the high-level block chain network corresponding to the operation node of the operation record for storage according to the time stamp of the operation record. For example: the operation record corresponding to the data ID123456 is:
2017-11-01-17:37:18 dataId＝123456，owner＝A，operator＝A，action＝delete；
2017-08-13-14;
2017-04-10-18;
writing the operation record according to the sequence of the time stamps, wherein the writing sequence is as follows:
2017-04-10-18;
2017-08-13-14;
2017-11-01-17:37:18 dataId＝123456，owner＝A，operator＝A，action＝delete；
and writing the operation record into the advanced node of the advanced block chain network corresponding to the operation node of the operation record for storage according to the operation node of each operation record. The operation node of the first operation record is node a, the operation record is written by the advanced node of the advanced blockchain network corresponding to node a, that is, the advanced node of the advanced blockchain network corresponding to node a creates data with data ID of 123456, and the data content of the data is input as data content 1; the operation node of the second operation record is node B, and the operation record is written by the advanced node of the advanced blockchain network corresponding to node B, that is, the advanced node of the advanced blockchain network corresponding to node B updates the data with data ID of 123456, and the updated data content is data content 2; the operation node of the third operation record is node a, and the operation record is written by the advanced node of the advanced blockchain network corresponding to node a, that is, the advanced node of the advanced blockchain network corresponding to node a deletes the data with the data ID of 123456.
By writing each operation record according to the sequence of the time stamps and writing each operation record by the advanced node of the advanced block chain network corresponding to the operation node of the operation record, the correctness of the data source is ensured.
In an exemplary embodiment, when each obtained operation record is correspondingly written into the advanced blockchain network for storage, the advanced node in the advanced blockchain network generates a key for each data and saves the key when writing the operation record. When the operation record of the data is written and stored, the operation record is encrypted by the key corresponding to the data, so that the data leakage is prevented, and the safety of the data is ensured.
In step S205, the data authority owned by the lower level node is obtained from the lower level node.
The data authority owned by the lower level node refers to the data authority of the lower level node to all data stored in the lower level blockchain network, and the data can be created by the lower level node or created by other lower level nodes in the lower level blockchain network. The data rights of each data may be different for the lower node, e.g., lower node A has read rights for data with data ID123456, write rights for data with data ID 123457, etc.
Step S206, each data authority is written into the high-level node for storage.
In the exemplary embodiment, each acquired data authority is written into the high-level node corresponding to the low-level node, and the migration of the operation record and the data authority is completed, so that the low-level blockchain is upgraded, and data omission or missing during upgrading is prevented. In an exemplary embodiment, said writing each data right to the superordinate node for storage comprises:
and according to the authorization node of each data authority, sending a corresponding authorization request to a node in the advanced block chain network corresponding to the authorization node.
The authorized node of the data authority refers to a node owned by data corresponding to the data authority, for example, if the node owned by the data with the data ID of 123456 is node a, the authorized node of the data is node a.
The authorization request is a signal for requesting authorization sent to the owning node of the data when other nodes need to use or view the data, and when the owning node of the data receives the authorization request, whether authorization is allowed can be determined.
When receiving the authorization permission signal sent by the node in the advanced block chain network corresponding to the authorization node, writing the data authority into the advanced node for storage.
In the exemplary embodiment, when the low-level node receives the authorization permission signal sent by the node in the high-level blockchain network corresponding to the authorization node of the data authority, the data authority is written into the high-level node for storage, and the migration of the data authority is completed. By sending an authorization request to authorize, the data permission in the high-level node can be traced, the validity of the data permission is ensured, and the integrity of the data migrated by the low-level block chain network is also ensured.
In an exemplary embodiment, after connecting the lower level node of the lower level blockchain network and the higher level node of the higher level blockchain network corresponding to the lower level node, respectively, when receiving an upgrade request for the blockchain network, further comprising:
when receiving an operation request of a user to the low-level node, recording the operation content of the user to the low-level node;
and when a signal that the operation content is successfully operated is received, generating a latest operation record according to the operation content and storing the latest operation record in a latest operation record list.
In the exemplary embodiment, the latest operation record is recorded in the latest operation list, so that the user can normally use the blockchain network in the upgrading process of the blockchain network, the normal work requirement of the user on the blockchain network is ensured, and the user experience is improved.
After writing each data authority into the high-level node for storage, the method further comprises the following steps:
writing each recent operation record in the recent operation records into the advanced block chain network in sequence;
and when a write success signal sent by the advanced block chain network for each latest operation record is received, deleting the latest operation record from the latest operation record list.
In the exemplary embodiment, after each operation record in the lower node and the migration of the data authority are completed, each latest operation record in the latest operation record list is correspondingly written into the higher-level block chain network. The writing method is consistent with the operation record and the data authority migration method, and therefore, the description is omitted. And when each latest operation record is successfully written, the node of the advanced block chain network corresponding to the latest operation record sends a writing success signal, and when the writing success signal is received, the latest operation record is deleted from the latest operation record list. And circularly writing until the migration is completed without the latest operation record in the latest operation record list.
In an exemplary embodiment, after deleting the last operation record from the last operation record list when receiving a write success signal sent by the advanced blockchain network for each last operation record, the method for upgrading the exemplary blockchain network further includes:
when the last operation record list is detected to be empty, the low-level node is deactivated, the high-level node is activated, and the connection with the low-level node and the high-level node is disconnected.
In this exemplary embodiment, that the latest operation record list is empty means that there is no latest operation record in the latest operation record list, that is, it means that all data in the latest operation record list has been successfully written into the advanced block chain network. Thus, the low level node is taken out of service, the high level node is enabled, and the connections to the low level node and the high level node are disconnected, and the upgrade of the blockchain network is completed.
