Description

A Sovereign Consortium Chain of Cone Blockchain

technical field

The invention belongs to the technical field of blockchain, and in particular relates to a sovereign alliance chain of a cone blockchain.

Background technique

The essence of blockchain is an open source distributed ledger. It is the core technology of Bitcoin and other virtual currencies. It can efficiently record the transactions of buyers and sellers, and ensure that these records are verifiable and permanent. At the same time, the blockchain itself has the characteristics of decentralization, disintermediation, information transparency, immutability and security. The blockchain has problems such as no government supervision and low security.

Blockchain is divided into public chain, private chain and alliance chain. The Bitcoin we are familiar with is the public chain, which refers to a consensus blockchain that anyone in the world can read, send transactions and obtain valid confirmation. Any node of the public chain is open to anyone, everyone can participate in the calculation in this blockchain, and anyone can download and obtain the complete blockchain data, that is, the entire ledger.

The alliance chain is jointly maintained by the member nodes in the alliance, and the nodes can join the alliance network after authorization, and only open all or part of the functions for alliance members. Some nodes are pre-designated as bookkeepers. The generation of each block is jointly decided by all bookkeepers. Other nodes can trade, but have no bookkeeping rights.

The alliance chain has the characteristics of partial decentralization, strong controllability, data will not be disclosed by default, and the transaction speed is very fast. However, the alliance chain has some defects:

The alliance chain is still highly dependent on the center. The alliance chain is controlled by multiple centers, and the system is jointly distributed and recorded by several authoritative institutions, and these nodes coordinate their work according to the consensus mechanism. Validating transactions requires an internal decision by the consortium. Each node corresponds to an entity. If any entity node wants to join the alliance chain, it needs to obtain the permission of the alliance chain, which will increase the power of the alliance leader node, which is not conducive to the equal transaction and verification of all nodes, resulting in the lack of consensus in the alliance chain. Safe and secure.

Membership verification of the existing consortium chain is determined by the inside of the consortium chain, lack of government supervision, and the lack of mutual communication and authentication between the existing consortium chains, which makes the consortium chain transactions lack security guarantees, which is not conducive to the fairness of the internal transactions of the consortium chain.

As shown in Figures 1 to 5, a sovereign alliance chain, each cone blockchain is a cone sovereign chain, and a consensus is reached between each cone sovereign chain to form a sovereign alliance chain; Information transmission and authentication are carried out through multiple consensus blocks; point-to-point data communication is carried out between each cone sovereign chain through standard transmission units, and broadcast information is sent to the consensus blocks.

As shown in Figure 2, the information of the standard transmission unit includes: the cone block chain terminal code, the registered person-identity-machine-integration authentication node block code, the personal identity authentication node block code, and the legal person identity authentication node block code.

As shown in Figure 3, when any node accesses the sovereign alliance chain, it needs to authenticate the node. The authentication process is as follows:

(1) The node is registered on the cone block chain, and passes the authentication of the block chain of the person-identity-machine-integration authentication node block, the personal identity authentication node block, and the legal person identity authentication node block;

Nodes include but are not limited to individual user blocks, legal person user blocks, as well as some institutions and organizations.

Among them, the specific implementation steps of the identity verification of the individual user block or the legal person user block are:

Cone blockchain terminal client user opens the client through his biometric authentication, and sends an authentication request to the registered human-identity-machine authentication node block and personal identity authentication node block;

The authentication node block for the integration of human, ID and machine authenticates the sent terminal identification, terminal number and the bound ID card number. After the authentication is passed, it sends a message to the identity authentication node block corresponding to the ID number that the integration of human and ID card has passed. news;

The identity authentication node block receives the authentication request sent by the terminal client of the cone blockchain and the message that the authentication node block of the integration of the human and the machine is authenticated. The biometric information is compared with the information retained in the identity authentication node block. After the comparison is successful, the authentication is completed.

(2) The node authentication is completed, the node block code is generated in the cone block chain, and the block code information is broadcast to the consensus block;

(3) The consensus block includes the consensus block of the sovereign cone chain and the consensus block of the non-sovereign cone chain; after the consensus block receives the broadcast information, the coding information of the node block, administrator information, etc. are stored in the corresponding position .

As shown in Figure 5, the specific implementation steps of two-way identity authentication for different sovereign cone blockchain nodes are as follows:

(1) The authentication and authenticated node blocks are registered on the cone block chain, and the node block code hash value is stored in the total cone block corresponding to the sovereign cone chain;

The authentication node block and the authenticated node block are in two cone blockchains respectively. The authentication node block code is saved in the total cone block of its own cone blockchain through verification, and the authenticated node block code After verification, it is stored in the total cone blocks of this cone block chain.

(2) The authentication node block initiates an authentication request for the authenticated node block, the authentication node block passes the authentication of this cone blockchain, and the authentication result is sent to the authenticated node block;

(3) The authenticated node block needs to pass the authorization and authentication of this cone block chain, and the authorization authentication result is sent to the authentication node block;

And the server identifier, to realize the authentication of the relevant information of the authenticated node block by the authentication node block.

In the same way, the certified node block can also obtain the code address, network address and server ID of the certified node block from the total block of the sovereign cone blockchain where the certified node block is located to realize different sovereign cone blockchains. Two-way authentication between blocks.

For example: A and B are two terminal client users of the cone blockchain, and the mutual verification steps of A and B in the cone blockchain are as follows:

After the terminal client user of the Cone blockchain has passed the block authentication of the human-identity-machine authentication node block and the identity authentication node block authentication of the Cone blockchain, the authentication QR code is generated by the authentication result and timestamp and sent to B-cone blockchain terminal client;

A Cone blockchain terminal client user broadcasts the authentication result to the Cone Consortium chain network at the same time, and sends the standard transmission unit to the B Cone blockchain terminal client user;

The user login of the B-cone blockchain terminal client is similar to that of A. After passing the authentication of the B-cone blockchain, scan the authentication QR code sent by the A-cone blockchain terminal client user to obtain the A-cone block. The block code of the authentication node, personal identity authentication node block code, legal person identity authentication node block code, and terminal code registered by the chain terminal client are obtained through the total cone block of the Cone blockchain. The encoded address, network address, and server identifier of the B-cone blockchain terminal.

In the same way, the terminal client user of the A-cone blockchain can also authenticate the terminal client user of the B-cone blockchain.

A-cone blockchain terminal client users and B-cone blockchain terminal client users can verify each other, and can also transmit information to each other, conduct real-time communication, etc.

If it is a legal person user, it also needs to pass the authentication of the cone blockchain legal person identity authentication node block.

In this embodiment, A and B are users of the two cone blockchains, respectively, and may also be some institutions, organizations, etc. that access the cone blockchains.

For example: C is the terminal client user of the sovereign cone blockchain, and D is the terminal organization of the sovereign alliance chain. Agency D initiates the authentication of user C. Agency D needs to pass the identity authentication on the sovereign cone blockchain, and broadcast the authentication result to the cone alliance chain network;

User C of the sovereign cone blockchain receives the broadcast, and at the same time initiates an authorization authentication request to the total cone block of the sovereign cone blockchain where user C is located;

The sovereign cone blockchain where user C is located will verify the block code information of the agency D, and send the authorization and authentication results to the agency D;

The agency D of the sovereign cone blockchain receives the authorization and authentication message, and will obtain the coded address, network address and server identification from the total cone block of the cone blockchain where the user C is located, so as to realize the authentication of the D agency of the cone alliance chain to C. User authentication.

In the same way, user C can also authenticate the agency D and obtain the block code address, network address and server ID of agency D.

As shown in Figures 6 and 7, the node block is the top-level block of the pyramid block; the itemized unit block is the middle-level block of the pyramid block, which belongs to the classification block of the node block and belongs to the node block. Sub-block; the user block is the bottom block of the pyramid block.

Each sub-block in the cone block is composed of a block header and a block body. The block header mainly contains the block code, the associated block hash value, the service network address, the server ID, the timestamp, and the administrator information. Hash value, block content hash value, block body contains administrator information, block content. The administrator information includes the administrator's registration, modification, and cancellation; the block content includes verification content, associated verification content, and other block content.

The user block can apply for a secondary unit block and a secondary user block according to its own service content, such as providing a public platform; the user block, the secondary unit block and the secondary user block also form a cone area piece. Some institutions also have no user block, or no sub-unit block.

Cone block chain structure, including several cone blocks, one of which is the total cone block, and other cone blocks are divided according to their category or nature: cone blocks of the same category or nature Node blocks located in the same column, and the node blocks in the pyramid blocks on the same column are connected to form a linear chain; according to the different categories or properties, a linear chain of several columns is formed; the linear chains of different columns intersect in the total cone The node blocks in the block form a pyramidal blockchain structure as a whole.

Cone blocks on the same column are layered according to levels and form a private chain according to the associated consensus relationship; linear chains of different columns form a cone alliance chain according to the consensus relationship; A row consists of more than one cone block of the same level on the same level.

Private chain: institutions of the same nature, located in the same column of the cone block chain, each cone block forms a private chain according to the consensus relationship; alliance chain: institutions of different nature, located in different columns of the cone block chain, each cone block The body block forms a consortium chain according to the consensus relationship; specifically: it can be divided into different levels 3-6 according to the ownership level (or subordinate level).

For example, the connection between Shanxi Provincial Public Security, Shuozhou Public Security, and Pinglu District Public Security is a private chain; the connection between Shanxi Provincial Public Security, Shanxi Civil Affairs Bureau, Shanxi Provincial Labor Bureau, etc. is an alliance chain.

The hierarchical relationship from top to bottom is: node block, itemized unit block, user block, secondary unit block, secondary user block, and microblock.

The node block, the itemized unit block and the user block respectively generate their corresponding administrator and administrator hash values, wherein the node block administrator hash value includes the hash value of the sub-item unit block administrator , the sub-unit block administrator hash value includes the subordinate user block administrator hash value; the information changes in each administrator can form a hash value and broadcast through the cone blockchain.
