Block chain recording method based on hierarchical heterogeneous dynamic topology slicing

Abstract

The invention discloses a block chain recording method based on hierarchical heterogeneous dynamic topology slicing, the method constructs a hierarchical heterogeneous dynamic topological slice for each block chain data record by using a simulated plant growth algorithm (PGSA) in a local network, the constructed two-layer heterogeneous dynamic topology consists of two parts, the common link and the main net, and the common link bears no more than 49% of the total number of nodes, and the main net bears no less than 51% of the total number of nodes. The nodes of the main network slice are usedto store data in a distributed manner, and the nodes of the common network slice are used to record the 256-bit Hash value after a specific encryption method (such as MD5, SHA 256, SHA 512, etc.). A layered heterogeneous dynamic topology slicing algorithm is combined with block chain recording to effectively solve that problem of 'ternary paradox' commonly faced by block chain data recording on the premise that the block chain technology is guarantee to be used for realizing the existing distributed recording technology.

Description

technical field [0001] The invention relates to the technical field of block chains, and relates to a block chain recording method based on layered heterogeneous dynamic topological sharding. Background technique [0002] Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Blockchain technology uses encryption algorithms, consensus mechanisms, and time-stamped chain block structures Store data, thereby adding a time dimension to the data, and realize point-to-point transactions, coordination and collaboration methods that rely on a certain credit center in a distributed system, achieving high efficiency, security, tamper-proof, and strong verifiability and features such as traceability.

Problems solved by technology

[0003] Blockchain technology has always been developed based on the virtual digital currency represented by Bitcoin. The application of digital currency is a set of ledger system and currency issuance mechanism, but there is a very serious "trilemma" problem: the application of digital currency Generally, the ultimate pursuit of decentralization and security is pursued, so each node must store all transaction data, and a large amount of computing power is wasted in the process of reaching consensus. For example, Bitcoin stores all nodes on the public chain. The time to generate a block reached 10 minutes, sacrificing efficiency;

It is unacceptable in financial and other systems that require extremely high data security

[0006] At the same time, although the network nodes using blockchain technology have achieved decentralization, the topological structure of these nodes is the same, and it is still not safe enough in the face of attacks with large-scale computing power;
