Research on Anonymization and De-anonymization in the Bitcoin System
It addresses privacy and security concerns for Bitcoin users and researchers, but is incremental as it primarily surveys existing methods.
This paper reviews existing anonymization and de-anonymization techniques in the Bitcoin system, such as coin-mixing and transaction chain analysis, and suggests directions for future research without presenting new experimental results or numerical improvements.
The Bitcoin system is an anonymous, decentralized crypto-currency. There are some deanonymizating techniques to cluster Bitcoin addresses and to map them to users' identifications in the two research directions of Analysis of Transaction Chain (ATC) and Analysis of Bitcoin Protocol and Network (ABPN). Nowadays, there are also some anonymization methods such as coin-mixing and transaction remote release (TRR) to cover the relationship between Bitcoin address and the user. This paper studies anonymization and de-anonymization technologies and proposes some directions for further research.
