Problems solved by technology
[0008] The purpose of the present invention is to address the existing block chain address association clustering method without considering the defects of mixed currency transactions in the Ethereum scene, in order to realize the address association in the Ethereum mixed currency scene, to solve the problem caused by the Ethereum mixed currency contract The unlinkability of deposit and withdrawal transactions leads to technical problems that are difficult to trace, and creatively proposes a heuristic address association method for Ethereum mixing contracts

Embodiment Construction
[0036] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] The embodiment of the present invention is to apply the heuristic address association method based on the Ethereum mixed currency contract to the Tornado Cash non-custodial mixed currency contract mixed currency transaction scenario, and verify the effectiveness of the method in the Ethereum mixed currency contract scenario sex.
[0038] Among them, Tornado Cash is a non-custodial decentralized currency mixing service tool deployed through the smart contract of Ethereum. It uses zero-knowledge proof to destroy the linkability between two deposits and withdrawal transactions of blockchain users, confusing Associations between addresses belonging to the same user. The user can complete the currency mixing by simply calling the deposit and withdrawal function in the contract with different addresses using the certificate that is not on the ...

The invention relates to a heuristic address association method for an Ethereum mixed currency contract, belongs to the technical field of block chain application, realizes address association in an Ethereum mixed currency scene, and solves the technical problem of difficulty in tracing due to non-linkability of deposit and withdrawal transactions of the Ethereum mixed currency contract. According to the method, two user behavior modes in an Ethereum non-hosted intelligent contract-based mixed currency service scene are put forward for the first time. The heuristic address clustering method suitable for the Ethereum mixed currency scene is provided for the first time, and three heuristic address clustering rules suitable for the Ethereum mixed currency contract are provided by analyzing the time interval of the mixed currency transaction and the behavior pattern of the user. The heuristic address clustering rule is applied to a popular mixed currency contract transaction set on Ethereum for actual analysis for the first time, and the validity of the heuristic address clustering rule is verified. According to the method, the non-linkability of Ethereum mixed currency transactions is reduced, and the cryptocurrency market and the transaction entities thereof are normatively supervised.
Description
technical field [0001] The invention relates to a heuristic address association method for an Ethereum mixed currency contract, belonging to the technical field of blockchain applications. Background technique [0002] As the blockchain model with the largest usage and the second largest market value at present, Ethereum is favored by many users who need privacy protection because of its characteristics of anonymity and decentralization. However, since the information on the blockchain is stored on the public chain in the form of distributed ledgers, any node can obtain complete information from the chain, and through analysis, it can discover the association between addresses, and even combine The off-chain data infers the user's identity information. [0003] With the emergence of more and more privacy analysis technologies, users' demand for better concealment of their transactions and address information is also increasing. As a result, many coin-mixing services to help...
