It can be seen that, by implementing the multi-chain coordination method based on the block chain described in fig. 1, the transmission of the transaction data between the upper block chain and the sub-block chain can be completed without affecting the block packing generation of each block, so that on this basis, the upper block chain can store a large amount of data and implement the interaction with each sub-block chain, and meanwhile, on this basis, the corresponding capacity expansion operation can be performed on the block chain at any time, thereby solving the problem of inconvenient interaction and capacity expansion between the block chains at present.
Example two: referring to fig. 2, fig. 2 is a schematic flowchart of another block chain-based multi-chain coordination method according to an embodiment of the present application. The block chain based multi-chain matching method illustrated in fig. 2 is improved according to the block chain based multi-chain matching method illustrated in fig. 1. The multi-chain matching method based on the block chain comprises the following steps:
s201, acquiring transaction data sent by a super node in a subrank block chain; the super node is used for verifying the authenticity of the transaction data in the sub-level block chain.
In this embodiment, the multi-chain coordination method based on the block chain is applied to an upper block chain, and the upper block chain is used for connecting a plurality of sub-level block chains; wherein each sublevel blockchain included in the plurality of sublevel blockchains is used for transmitting transaction data and/or receiving a block.
In this embodiment, the superior blockchain acquires transaction data sent by a super node in the subordinate blockchain, and performs authenticity verification according to the transaction data. It can be seen that the method defines a specific chain structure of the sub-level blockchain interacting with the upper level blockchain, thereby defining an application scenario to indicate that the method is applied to the block chain with the super nodes in the sub-level blockchain. Meanwhile, by implementing the implementation mode, the multi-chain matching basis of the method can be determined as the sub-level block chain with the super node, so that respective operation can be completed under the condition of meeting the condition of no interference among chains, the integrating degree among the multi-chains is improved, and the multi-chain matching effect is improved.
In this embodiment, the super node is used for uploading transaction data and for verification and block output operation in the sub-level block chain.
And S202, performing authenticity verification by taking the transaction data as a basis.
In this embodiment, the higher-level block chain performs authenticity verification based on the transaction data, and therefore authenticity of the transaction data can be guaranteed on the basis that the transaction data passes authenticity verification, and authenticity of contents of the block chain is determined.
S203, acquiring a data label corresponding to the transaction data.
In this embodiment, the data tag corresponding to the transaction data is a way for finding the transaction data in the block after the block is acquired by the sublevel blockchain. The function of the tag is similar to the index function, and further description is omitted here.
In this embodiment, the type of the data label is not limited, and specifically, the data label may be obtained by performing hash algorithm calculation.
And S204, carrying out combined processing according to the transaction data and the data label to obtain transaction information.
In this embodiment, the transaction data is initially acquired transaction data, and the data tag is an index tag of the transaction data, so that the transaction information is combination information of the transaction data and the data tag, and the combination information can be directly applied to packaging or block output.
In this embodiment, the combined information (transaction information) can be reprocessed to implement the matching between the transaction information and the block.
And S205, packaging the transaction information according to a preset hash algorithm to obtain a block corresponding to the transaction information.
In this embodiment, the hash algorithm may be a preset algorithm, and is not limited in this embodiment.
In this embodiment, the hash algorithm is also called hash algorithm, and is to map a binary value of any length to a binary value of a shorter fixed length, and this small binary value is called a hash value. Briefly, the principle is to convert a piece of transaction information into a string of fixed length.
S206, broadcasting the blocks into the sub-level block chains so as to synchronize the nodes in the sub-level block chains.
In this embodiment, the step of broadcasting the block into the plurality of sub-level block chains provides the multi-sub-level block chains with a capability of acquiring the transaction information in the upper-level block chain, and the transaction information may be provided by other sub-level block chains.
In this embodiment, the meaning of synchronization is in synchronous storage, and the specific step is used to indicate that the service or transaction that the full node in the superior block chain passes through the verification can be sent to the super node or the common node in the subordinate block chain for synchronization.
In this embodiment, the execution main body of the method may be an upper-level block chain connected to the sub-level block chain, or may be a full node in the upper-level block chain connected to the sub-level block chain (the full node may refer to a node in the block chain, and the full node is intended to indicate that the node is complete and powerful), and a specific type of the execution main body may further include other execution devices and control devices, which is not limited in this embodiment.
For example, the idea in this embodiment is for the underlying architectural design of a blockchain. For the grouping algorithm, partial verification, block output, storage and other work in the group can be handed over to all nodes included in the upper block chain. And an upper block chain provides an interface for each independently operated sub-block chain to call. Wherein, each independently operated sublevel block chain can contain super nodes and common nodes. And the super node and the common node in the sub-level block chain can initiate service or transaction. Only, after passing through the super node, the service or transaction initiated by the ordinary node is sent to the whole node by the super node to perform subsequent verification, block output, storage and other work. Meanwhile, the service or transaction passing the verification of the whole node can be sent to the super node or the common node in the group for synchronization.
Therefore, by implementing the embodiment, the independently operated sub-level block chains can be ensured to independently complete the transaction inside. Moreover, each sub-level block chain only sends the data of the transaction to the upper level block chain, so that the upper level block chains are synchronized. The operation mechanisms in the sub-level block chains can be different, and only the independent sub-level block chains can operate independently and can broadcast the transaction data to the main chain. In the process, as long as the superior block chain can normally run, the normal execution of the method can be ensured.
In this embodiment, the method can be extended to Bingpene blockchains, EtherFang, EOS (a piece of blockchain operating system designed for commercial distributed applications), and so on.
It can be seen that, by implementing the multi-chain coordination method based on the block chain described in fig. 2, the transmission of the transaction data between the upper block chain and the sub-block chain can be completed without affecting the block packing generation of each block, so that on this basis, the upper block chain can store a large amount of data and implement the interaction with each sub-block chain, and meanwhile, on this basis, the corresponding capacity expansion operation can be performed on the block chain at any time, thereby solving the problem of inconvenient interaction and capacity expansion between the block chains at present.
