Embodiment Construction

[0059] In reality, in some transaction scenarios, the probability of transactions between any nodes in the entire network is not the same, and has obvious local characteristics, that is, in the P2P entire network of the blockchain, the probability of transactions between nodes in certain regions It is much higher than the probability of transactions with nodes outside the region, or the probability of transactions between nodes in some groups is much higher than the probability of transactions with nodes outside the group. Using such locality of transaction probability, global The splitting of the online ledger data also splits the accounting load of transaction information. Of course, such splitting cannot affect the transaction function between any nodes in the entire network.

[0060] Specifically, the present invention discloses a method for splitting the whole network of blockchain, including:

[0061] Step 100, splitting the nodes of the entire network into several node ...

Abstract

The invention relates to a block chain whole network splitting method. The method comprises the following steps: dividing a whole network into a plurality of sub networks according to local transaction features of a block chain network, splitting global data of the block chain to form sub network data, creating a new block based on a consensus competition mechanism in the sub networks, and storing the sub network data in areas, thereby saving storage resources and computing power resources; and using a node multi-public key address scheme and a node single public key address scheme to solve the problem of cross-network movement and cross-network transfer account transaction of different sub networks. The method is based on the core protocol of block chains, the expandability problem of the data layers of the block chains is solved, and meanwhile no additional security problem is solved.

Description

technical field [0001] The invention belongs to the technical field of block chains, and relates to a balanced distribution method of block chain global data in the whole network based on the locality characteristic of transaction frequency. Background technique [0002] In recent years, the practice of digital currency represented by Bitcoin has gained widespread attention. The underlying technology platform of digital currency is blockchain (Blockchain) technology. The essence of blockchain technology is a distributed database, which stores historical transaction data. This database Shared by all nodes through a distributed consensus protocol. The core value of blockchain technology includes decentralization, distributed consensus, signature and encryption of asymmetric secret keys, and time stamps. In a distributed system where nodes do not need to trust each other, peer-to-peer transactions based on decentralized credit, coordination and Collaboration, thus providing a ...
