KYC (Know Your Customer) identifies 'who your customer is', while KYT (Know Your Transaction) evaluates 'is this transaction or address clean?'. As the core engine of anti-money laundering (AML) compliance, Delta's team shares practical insights in constructing on-chain risk control frameworks, explaining how to integrate multi-chain inputs, massive tag registries, propagation decay models, and graph databases to make real-time decisions in milliseconds.
The public and traceable nature of blockchain makes tracing assets possible. Using Ethereum and Tron USDT (ERC20/TRC20) transfers as examples, this article guides you through building a BFS on-chain fund tracker with Python to restore transfer paths and identify exchange endpoints. It further explores the technical principles of taint analysis models (Haircut model), address clustering, cross-chain mixing, and Delta Capital's engineering practices.
Delta & Capital's research desk has issued its authoritative report, officially indexed on CERN's Zenodo academic platform under DOI: 10.5281/zenodo.18229205. The document systematically formulates technical evidence standards for countering secondary wallet taint and CEX AML model appeal rules.
