The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

Referring to fig. 1, a flow chart of a block chain-based electricity fee settlement method according to an embodiment of the present invention includes S1-S6:

s1, generating a first blockchain according to a first node corresponding to a green electricity purchaser, generating a second blockchain according to a second node corresponding to a green electricity producer, and establishing a trusted cross-chain channel between the first blockchain and the second blockchain.

It is worth mentioning that when the transaction electricity fee data settlement is carried out between the green electricity purchasers and the green electricity manufacturers, data interaction is needed. The scheme can generate a first blockchain corresponding to the green electricity purchaser and a second blockchain corresponding to the green electricity producer, and then a trusted cross-chain channel is established between the first blockchain and the second blockchain, so that data interaction and verification are realized.

In some embodiments, S1 (generating a first blockchain from a first node corresponding to the green electricity purchaser, generating a second blockchain from a second node corresponding to the green electricity producer, establishing a trusted cross-chain channel between the first and second blockchains) comprises S11-S13:

And S11, connecting the first nodes corresponding to all the green electricity purchasers to generate a first blockchain, wherein the first blockchain is configured with a first blockbook so that any one first node can record when finishing transaction or verification.

It can be understood that the first blockchain is composed of a plurality of first nodes corresponding to green electricity buyers, wherein the first blockchain is configured with a first blockbook, so that any one first node can record when finishing transaction or verification. It is understood that the first blockchain can realize the true record of the transaction behavior data of the green electricity purchasers and prevent the tampering.

And S12, connecting second nodes corresponding to all green electricity manufacturers to generate a second blockchain, wherein the second blockchain is configured with a second blockbook so that any one second node can record when finishing transaction or verification.

And the same as the step S11, the scheme connects the second nodes corresponding to all green electricity manufacturers to generate a second blockchain, wherein the second blockchain is configured with a second blockbook so that any one of the second nodes can record when finishing transaction or verification. It will be appreciated that the actual recording of green electricity generator transaction data may be achieved through the second blockchain, preventing tampering.

S13, a first cross-chain component, a second cross-chain component and a management component which are included in the trusted cross-chain channel are generated, the first block chain, the first cross-chain component, the second cross-chain component and the second block chain are sequentially connected, and the management component is respectively connected with the first cross-chain component and the second cross-chain component.

Referring to fig. 2, in order to enable data interaction between the first blockchain and the second blockchain and achieve electricity fee settlement between the green electricity producer and the green electricity purchaser, the scheme is provided with a trusted cross-chain channel to communicate the first blockchain and the second blockchain.

The trusted cross-chain channel comprises a first cross-chain component, a second cross-chain component and a management component, wherein the first block chain, the first cross-chain component, the second cross-chain component and the second block chain are sequentially connected, and the management component is respectively connected with the first cross-chain component and the second cross-chain component.

It should be noted that, when a node performs a transaction, an upper node is generally required to perform verification. For example, a group company includes a parent company, a subsidiary company and a grandchild company, and when the grandchild company makes a transaction, the subsidiary company and/or the parent company need to agree to make the transaction, otherwise the transaction cannot be made.

The first level structural relationship may be a structural relationship corresponding to the first node. Similarly, the second level structural relationship is a structural relationship corresponding to the second node.

s21, determining the corresponding upper node according to the node label corresponding to each first node, and if the determined node label of the upper node does not have other corresponding upper nodes, obtaining the substructure relation of the corresponding first node.

For example, the first node is a child of the parent, child and grandchild, and when the node label (parent) of the determined upper node does not have the corresponding other upper node, the child structure relationship of the corresponding first node is obtained. It will be appreciated that in this case the first node has only one superordinate node. At this time, the child structure relationship may be a parent company-child company.

And S22, if the node labels of the determined upper nodes are judged to have other corresponding upper nodes, counting all the upper nodes to obtain all the upper nodes corresponding to the first nodes, and obtaining the substructure relation of the corresponding first nodes.

For example, the first node is a grandchild company of the parent company, the child company, and the grandchild company, and when the node label (child company) of the determined superior node has the corresponding other superior node (parent company), the child structure relationship of the corresponding first node is obtained. It will be appreciated that in this case the first node has a plurality of superordinate nodes. At this time, the child structure relationship may be parent-child-grandchild.

The method and the device can generate a corresponding first structure table by combining the number of the first nodes, wherein the first structure table comprises corresponding unit groups corresponding to each first node, and the corresponding unit groups comprise node grids of the current level and node grids of the upper level. It should be noted that when the corresponding node does not have a superior node, the superior node grid may not be constructed.

And S252, filling the node identity information of each first node into the corresponding node grid of the current level, and filling the identity information of the upper node into the upper node grid to obtain a first structure table with a first level structure relationship.

Through the mode, the first structure table can be obtained.

When determining the upper node, the corresponding sub-structure relationship can be utilized for determination.

After the trusted cross-chain channel judges that any one of the first nodes in the first blockchain uploads the green electricity purchase request, the configured purchase permission relationship and the green electricity purchase attribute corresponding to the green electricity purchase request can be utilized for combined verification, and the specific reference is below.

In some embodiments, S3 (the trusted cross-chain channel generates the first verification policy information corresponding to the first node according to the purchase permission relationship and the green electricity purchase attribute corresponding to the green electricity purchase request after determining that any one of the first nodes in the first blockchain uploads the green electricity purchase request) includes S31-S35:
