Information security researcher who was among the first to run Bitcoin
Dustin D. Trammell is an information security researcher based in Austin, Texas. He has worked in the cybersecurity industry and is known in the infosec community for his research on vulnerabilities and exploit development. He was among the very first people to download and run Bitcoin after its public release.
On January 11, 2009 — three days after Bitcoin v0.1 was released — Trammell emailed Satoshi Nakamoto after downloading and running the software. He reported his experience and asked questions about the system’s design. Satoshi responded the same day, beginning a brief but significant email correspondence.
Trammell began mining Bitcoin in its earliest days, potentially operating one of the first nodes on the network alongside Satoshi and Hal Finney. On January 14, 2009, Satoshi sent Trammell 25 BTC as a test transaction, making it one of the earliest known person-to-person bitcoin transfers (following the 10 BTC Satoshi sent to Hal Finney on January 12). In their correspondence, Satoshi discussed technical details including coin maturity rules and how the system handled new blocks.
Trammell’s early adoption and his direct correspondence with Satoshi place him among the very first Bitcoin users. His emails with Satoshi, preserved by the Satoshi Nakamoto Institute, provide a window into Bitcoin’s earliest days when the network consisted of only a handful of nodes.
