Embodiment 1

[0045] This embodiment provides a blockchain system with isomorphic dual-mode primary and secondary chains, including a data layer and a consensus layer,

[0046] The data layer sets dual block pointers, using two storage areas to store the hash value of the previous main mode block and the hash value of the latest secondary mode block after the last main mode block;

[0047] The consensus layer forms an isomorphic dual-mode primary and secondary chain architecture through dual block pointers, including a logical main chain and a logical secondary chain. In the main mode, the preset single-chain architecture proof-of-work difficulty update mechanism is adopted. In the secondary mode, the same The main mode has a multiple relationship proof-of-work difficulty update mechanism,

[0048] Among them, the relationship between the mathematical expectation of the workload proof difficulty update time in the main mode and the main mode workload proof difficulty update period D and the...

Embodiment 2

[0091] This embodiment provides a block production method based on the block chain system of the isomorphic dual-mode primary and secondary chains described in the first embodiment, please refer to Figure 6 , the method includes:

[0092] Step S1: Connect to the blockchain network, and transfer all the existing block information of the blockchain network to the host;

[0093] Step S2: Collect the accounting request from the client and store it in the block to be generated;

[0094] Step S3: Determine the auxiliary information according to the requirements, wherein the auxiliary information includes transfer postscript, instruction information, auxiliary security authentication information, and management information, which are stored in the block to be generated;

[0095]Step S4: Update the latest block information in the blockchain network in real time, point the main hash pointer of the block to be generated to the latest main mode block in the entire network according to ...

Abstract

The invention discloses a block chain system of an isomorphic dual-mode main and auxiliary chain and a block production method of the block chain system. The technical scheme adopted by the inventionis a novel block chain technical framework which gives consideration to the stability of a distributed database service and the updating timeliness of internal management information. Specifically, amain block chain pointer and an auxiliary block chain pointer are designed, a main mining mode and an auxiliary mining mode of a multiple difficulty relation are utilized, waste computing power is recycled, and a block chain is fitted into a logic main chain and a logic auxiliary chain, wherein the main mode block on the main chain is responsible for providing stable database service for the outside, and the auxiliary mode block on the auxiliary chain is responsible for providing timely updated auxiliary information mounting for the inside. By optimizing the structure of the block chain system, a set of logic double-chain structure is formed, and through out-of-main-chain service and in-auxiliary-chain management, the block chain stability service and the fast block production capability are considered.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain system of isomorphic dual-mode primary and secondary chains and a block production method thereof. Background technique [0002] The application of Internet technology has gradually penetrated into various fields of human activities. On November 1, 2008, the author signed by Satoshi Nakamoto published a paper describing in detail how to create a decentralized electronic trading system that does not need to be based on mutual trust between the two parties, and named this system Bit currency. With the birth of Bitcoin, its core blockchain technology once became the focus of scientific research and application hotspots in various industries. [0003] The application field of blockchain technology involves a wide range of industries and has extremely high security requirements. In the application environment, the security of blockchain has been raised to a very n...
