Embodiment Construction

[0015] see figure 1 As shown, the technical solution adopted in this specific embodiment is: it is between the chain structure and the DAG, and it includes a business receiving block 1 and a business result block 2, and the business receiving block 1 and the business result block 2 is split from the existing block, and uses DPOS (Delegated proof of stake) as the consensus protocol. This architecture is independent of the specific consensus algorithm, and other consensus algorithms such as DBFT, DPOS+BDFT, etc. can also be used. For the convenience of description and comparison with EOS, DPOS is used for description below.

[0016] Its technical implementation includes the following steps: 1) The designated block producer determined by DPOS receives the business and packs it in the business receiving block 1; 2) After the producer packs, it runs the smart contract 3, which belongs to Smart contracts 3 of different blocks can be parallelized, and there is no sequence relationsh...

Abstract

The invention relates to a heterogeneous parallel block chain and technical implementation thereof, and relates to the technical field of block chain bases. The heterogeneous parallel block chain is between a chain structure and a DAG, and comprises a service receiving block and a service result block; the service receiving block and the service result block are formed from existing blocks in a splitting manner; and furthermore, DPOS (Delegated Proof Of Stake) is used as a consistency protocol. The technical implementation of the heterogeneous parallel block chain comprises the steps that: a,an appointed block producer determined by the DPOS receives a service, and packs the service in the service receiving block; b, after packing, the producer runs a smart contract; and c, the producer packs a result in the service result block; and result nodes simultaneously verify two blocks: the corresponding service receiving block and the previous service result block. Parallel running of the smart contracts of different blocks can be realized; simultaneously, the security is ensured; the block verification speed is increased; the fast transaction and the verification speed can be improved;the speed is higher than that of chain structures, such as the EOS; the fast transaction can be supported; and simultaneously, the security cannot be reduced.

Description

technical field [0001] The invention relates to the technical field of the bottom layer of block chain, in particular to a heterogeneous parallel block chain and its technical realization. Background technique [0002] Existing blockchains adopt a chain structure (Bitcoin, Ethereum, EOS, etc.) or DAG (Directed Acyclic Graph), or a multi-chain structure. However, the existing chain structure cannot realize the parallel operation of smart contracts on different blocks, and can only realize the parallel operation of smart contracts in a single block, and the verification of DAG often has problems such as security and complexity. The multi-chain structure can be regarded as a parallel connection of multiple side chains (chain structure). Different side chains can realize the concurrent operation of different blocks (these blocks must be on different side chains), but it is impossible to realize the parallel operation of a certain side chain. The smart contracts of different blo...
