Abstract
FATF introduces a new regulation framework with Travel Rule in 2019, many crypto exchanges have incorporated the TRISA (Travel rule information sharing architecture) system as a part of their compliance mechanisms. However, the TRISA system may not meet the regulation requirements for all the countries. This paper proposes another version of TRISA, STRISA, that is compatible with the TRISA, but with four new features: 1) track individual digital wallets; 2) support a BDL (Blockchain Data Lake) platform that can interoperate with various blockchain (BC) systems for analysis; 3) supply a regulation enforcement framework using smart contracts with automated machine learning techniques; 4) Most of data are stored in associated BCs to ensure that no one including regulators should try to alter the data stored to protect the integrity of entire regulation compliance process. This paper also discusses other design and protocols to support these new features including unique storage scheme, double-interlocking mechanism. STRISA has been implemented and is available for research and experimentation.
