Embodiment Construction

[0040] First, the idea of ​​this application is explained. This application provides a block creation, addition, and distributed ledger establishment method based on structured DAG, so that nodes can reach consensus on a large-scale proof of work (PoW) mechanism and establish a unified distributed ledger. In addition, this application also provides a transaction pool transaction allocation method based on a structured directed acyclic graph (DAG), so that the probability of multiple miners processing a transaction can be ignored. As a result, without sacrificing security and decentralization, the capacity has been significantly expanded.

[0041] In the embodiment of this application, while using the proof-of-work mechanism (PoW) and the Satoshi Nakamoto consensus method, the chain structure is extended to the directed acyclic graph, so as not to sacrifice security and decentralization. The technical effects of expanding capacity, shortening latency, decentralizing mining comput...

Abstract

The invention discloses a block creation, addition and distributed account book establishment method and device based on a structured directed acyclic graph DAG. According to the method and the device, a workload proving mechanism PoW and a Chinese hearing consensus method are used, and meanwhile, a chain structure is expanded into the DAG, so that the technical effects of expanding the capacity,shortening the delay, decentralizing the mining computing power and increasing the transaction processing opportunity with low cost are achieved on the premise of not sacrificing the safety and decentralization.

Description

Technical field [0001] This application relates to the field of computer technology, in particular, to a block creation, addition, and distributed ledger establishment method and device based on a structured directed acyclic graph. Background technique [0002] Block chain (the full English name is Block Chain) technology is essentially a consensus mechanism design based on a chain structure that stores information on a peer-to-peer network in a distributed manner. Taking Bitcoin as an example, some transactions are grouped together and stored in a block less than 1 megabyte, and all blocks are connected in a chain structure. This may not be the most efficient way to store information. However, on the basis of integrity checking and verification using encryption functions such as hash algorithms, public keys, and private keys, the "Satoshi Nakamoto Consensus" proposed based on the chain structure has achieved security and decentralization. The emergence and development of Bitco...
