[0039] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0040] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0041] In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is further illustrated below in conjunction with the drawings and embodiments.

[0042] Embodiment One

[0043] The purpose of this embodiment is to provide a blockchain system based on a sharding protocol, as shown in Figure 1 including a collaboration chain, and a plurality of (n) work groups connected to the collaboration chain and a plurality of work chains connected to the collaboration chain that do not reach the storage upper limit, each work group is composed of a plurality of work chains based on a sharding protocol.

[0044] All work chains in a work group are logically a work chain, and each work chain in a work group is also called an intra-group partition of a work group.

[0045] The collaboration chain is responsible for managing the work chains and work groups, including a work chain management contract module and a collaboration chain asset contract module; the work chain management contract module includes a work chain registration information submodule and a work group partition information submodule; specifically:

[0046] The work chain registration information submodule is used to manage the registration and routing information of all work chains connected to the collaboration chain;

[0047] The work group partition information submodule is used to manage the work group partition information, that is, to manage which virtual bucket the intra-group partition of the work group is responsible for the new asset on-chain service;

[0048] The collaboration chain asset contract module is used to manage the deployment information of the asset contract, that is, to manage which work chain each type of asset contract is deployed on.

[0049] The work chain is a blockchain for executing specific business, including a principal account module (principal management module), an asset contract module, an asset on-chain module, and an asset use module; the asset contract module includes a transaction rule submodule and a load strategy submodule; specifically:

[0050] The principal management module is used to manage the access in and out and operation permissions of the principal (the party related to the data asset and other objects, which can initiate or receive transactions) in the intra-group partition;

[0051] The asset contract module includes a plurality of asset contracts for defining transaction rules and load strategies of each type of data asset on the work chain; wherein the transaction rule submodule is used to define asset metadata, asset state, asset operation rules and asset state transition rules; the load strategy submodule is used to define the load strategy of each type of data asset, and the load strategy refers to the balanced allocation method of a plurality of data on-chain requests of each type of data asset to the virtual bucket, which ensures efficient completion of data on-chain work and improves data on-chain service capability.

[0052] The load strategies of the same type of data assets are the same, and the load strategies of different types of data assets can be different, for example, the load strategies of an ID card and a driver's license can be different; assuming that the load strategy of a certain type of data asset (an ID card) is provided by the intra-group partition with the most remaining storage space, then as the on-chain of this type of data asset (an ID card), the intra-group partition with the most remaining storage space will definitely change, so different intra-group partitions will be selected at different time periods.

[0053] The asset on-chain module is used to provide new asset on-chain services of the intra-group partition;

[0054] The asset usage module is used to provide asset usage services of the existing data assets of the intra-group partition.

[0055] The sharding protocol includes a work group subject management module, an asset contract management module and a hash sharding module; specifically:

[0056] The work group subject management module is used to specify the permissions of the respective intra-group partition management subjects in the intra-group partition, and the work group does not provide unified permission management services;

[0057] The asset contract management module is used to specify the asset contract deployment rules of each intra-group partition in the work group, and requires that the number and type of asset contracts of each intra-group partition in the same work group should be completely the same, and the transaction rules and load strategies of the same type of asset contracts of each intra-group partition should be completely the same;

[0058] The hash sharding module configures a virtual bucket hash sharding method, which is used to virtualize the asset on-chain and usage service capabilities of each intra-group partition, introduce a virtual bucket layer to build a virtual bucket, and provide asset on-chain and usage services based on the virtual bucket.

[0059] For example, Figure 2As shown, the virtual bucket hash fragmentation method provides several (5) virtual buckets for each workgroup, each virtual bucket provides part of the asset on-chain and service, each work chain in the workgroup can provide asset on-chain and service for multiple virtual buckets, according to the asset load strategy, the virtual bucket to which the asset on-chain and service belongs is calculated, and then the in-group partition of the workgroup used by the asset is obtained. For the work chain that has reached the storage upper limit, when it is expanded into a workgroup, it can be configured not to provide new asset on-chain service and service for any virtual bucket, and only provide the use service of the original asset on the work chain.

[0060] The blockchain system based on the fragmentation protocol of the embodiment realizes the horizontal expansion of the performance and storage of a single blockchain by increasing the work chain and forming a workgroup based on the fragmentation protocol with the original work chain, breaks the limitation that a single blockchain can only be expanded vertically, improves the service capability of the work chain, and improves the sustainable development capability of the blockchain. A single blockchain can support larger-scale blockchain applications.

[0061] The blockchain system based on the fragmentation protocol of the embodiment, all blockchain in the workgroup are logically the same chain, avoids the problem that the inter-chain communication affects the performance after the horizontal expansion in the multi-chain mode, and realizes the synchronous expansion of the performance and storage.

[0062] Embodiment two

[0063] The purpose of the embodiment two is to provide a working method of the blockchain system based on the fragmentation protocol as described in the embodiment one, including the following steps:

[0064] Step 1, in response to the storage upper limit of the work chain (original work chain) outside the workgroup, expanding it into a workgroup, as shown in Figure 3 As shown, specifically including:

[0065] S101: add a new work chain, and deploy all asset contracts on the original work chain on the new work chain;

[0066] S102: deploy the same load strategy for the same type of asset contract on the original work chain and the new work chain;

[0067] S103: register the new work chain on the collaboration chain, and indicate the workgroup to which the new work chain and the original work chain belong, including:

[0068] S1031: take the chain name of the original work chain as the identifier of the workgroup in the collaboration chain;

[0069] S1031: add the workgroup information to which the original work chain belongs in the registration information of the original work chain in the collaboration chain;

[0070] S1031: Register the added work chain in the cooperation chain, and indicate the work group to which it belongs in the registration information.

[0071] Step 2, in response to the received data asset on-chain request, the data asset on-chain is carried out, as shown in the specific: Figure 4

[0072] S201: The client requests the asset ID of the partition in any group of the work group to generate a new asset, that is, the client sends an asset on-chain request; wherein the work group requested by the client is configured in the client, for example, the client in each region only requests the corresponding work group or work chain in the region;

[0073] S202: The partition in the group receiving the request obtains the work group partition information and the load strategy of the asset contract corresponding to the new asset in the work group;

[0074] S203: The partition in the group receiving the request generates an asset ID for the new asset, calculates the virtual bucket to which the asset on-chain service belongs based on the asset ID and asset load strategy, and calculates the partition in the group providing the on-chain service for the new asset according to the work group partition information;

[0075] S204: Add the chain name identifier of the partition providing the on-chain service calculated to the front of the asset ID to generate a new asset ID, and return the new asset ID to the client;

[0076] S205: The client obtains the on-chain service based on the chain name identifier in the new asset ID to the corresponding partition in the group, and completes the asset on-chain.

For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
