- Sarah Meiklejohn, a young mathematician, has revealed that Bitcoin transactions are traceable, challenging the prevailing belief in their complete privacy.
- Through her research, Meiklejohn used new techniques to link Bitcoin addresses to specific people, which helped solve major digital crimes.
- Her discoveries were documented in her book, and have revolutionized the field of combating cybercrime.
In a startling turn of events, Sarah Meiklejohn, a 27-year-old mathematician, has uncovered an interesting fact: Contrary to popular belief that Bitcoin provides complete privacy, her research has shown that Bitcoin transactions are more transparently traceable than existing financial systems, a discovery that could change… Rules of the game in cybercrime.
Sarah Meiklejohn, a computer science undergraduate at UC San Diego, walks through her office filled with random items purchased with Bitcoin, from calculators to DVDs. Obsessed with puzzles since childhood, Meiklejohn found herself fascinated by the world of digital currencies, especially Bitcoin. Over the course of weeks, she went through 344 Bitcoin transactions, trying to decipher them and trace their tracks.
Meiklejohn carefully recorded the details of each transaction in a spreadsheet, then used her transaction data to analyze the Bitcoin blockchain. It studied about 16 million transactions that occurred throughout Bitcoin’s history, which allowed it to track digital currency flows and link different addresses.
Meiklejohn has also developed ways to link multiple Bitcoin addresses together, identifying patterns that reveal users’ identities. The “clustering” technique was then used to link addresses that shared multiple transactions with entries, indicating that they belonged to the same person or organization.
Although Satoshi Nakamoto, the creator of Bitcoin, emphasized the complete privacy of its users, Meiklejohn was able to prove the opposite. It was able to reveal that Bitcoin transactions can be accurately tracked.
This discovery has had a major impact on the field of digital forensics, as researchers, technology companies, and law enforcement agencies can track and identify users with even greater transparency than the current financial system. Which helped solve complex crimes such as the theft of half a billion dollars in Bitcoin and dismantling the largest drug market on the dark web.
It is worth noting that Meiklejohn’s pioneering work opened new horizons in our understanding of digital currencies and their privacy properties. She documented this in her book “Tracers in the Dark: The Global Hunt for the Crime Lords of Cryptocurrency,” in which she presents her exciting journey in cracking Bitcoin, signaling the beginning of a new era in the fight against digital crime, where the perpetrators are no longer anonymous.
