Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see figure 1 , the present invention provides a method for clustering Ethereum addresses based on neighbor information aggregation, including:

[0027] Step 1. Construct address target graph and address transaction graph based on historical transaction data in the blockchain.

[0028] The definition of graph G= defines an Ethereum address as a node V in the directed graph, and at the same time, each edge E in the directed graph represents at least A transaction; L=v , l e > is a label set, l v is the verte...

Abstract

The invention provides an Ethereum address clustering method and device based on neighbor information aggregation. The method comprises the following steps: constructing an address target graph and an address transaction graph based on Ethereum historical transaction data; establishing a strong association address node mode graph and an exchange address mode graph based on neighbor node information in the transaction graph, and performing address node neighbor information aggregation; establishing a subgraph isomorphic CSP model, and performing clustering to obtain a strong association address node set and a transaction exchange address set. Compared with the prior art, the Ethereum address clustering method based on neighbor information aggregation provided by the invention can track the relevance between the address node and other address nodes, so that the mutual relation and source between the address nodes in the block chain transaction can be identified more accurately.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a clustering method and device for Ethereum addresses based on neighbor information aggregation. Background technique [0002] Blockchain is a kind of accounting technology jointly maintained by multiple parties, which can realize consistent data storage, non-tampering, multi-party access, and decentralization. It is also called distributed ledger technology. The blockchain provides new solutions to further solve the trust, security and efficiency problems in the Internet, and also brings new opportunities and challenges to the development of industries such as finance. In recent years, the application of blockchain technology has gradually become widespread, but the accompanying regulatory issues have also become more prominent. The design of blockchain anonymity and multi-party maintenance makes effective supervision of blockchain very difficult. [0003] As a re...
