We’ll demystify how these technologies operate and explore relevant OSINT techniques. Delving into real-world use cases, we’ll highlight how OSINT can help profile public personalities, identify victims of ‘rug-pull’ scams, and deanonymize Tornado Cash users. Join us for a comprehensive insight into the dynamic intersection of blockchain and OSINT.
