One software tool is what turned supposedly anonymous Bitcoin into something investigators can follow.
Who they are
Chainalysis Reactor, the company's proprietary blockchain-tracing tool.
What they do
The engine treats it as the working mechanism for cryptocurrency surveillance.
How it works
It groups related addresses together, tags them, and maps out transactions. It was central to tracing Silk Road Bitcoin (recovered from James Zhong a decade later) and the Colonial Pipeline ransomware payments.
Why it matters
It matters as the concrete tool that makes crypto traceable, undercutting the promise of anonymous digital money.
The engine's record — word for word
Chainalysis proprietary blockchain-tracing tool. Heuristic clustering + address tagging + transaction graphing. Instrumental in Silk Road BTC (James Zhong decade-after recovery) + Colonial Pipeline ransomware payment tracing. Operational mechanism for Joule-Paradox surveillance application.
