Who is Jameson Lopp?
Jameson Lopp studied computer science at the University of North Carolina at Chapel Hill, graduating in 2007. His introduction to Bitcoin came in 2012 after discovering the whitepaper, and a data breach at his workplace crystallized for him the critical importance of securing digital assets. He didn't just become a Bitcoin enthusiast. He became one of its most meticulous security researchers.
In 2015, Lopp launched Statoshi, a fork of Bitcoin Core designed to monitor the Bitcoin network for attacks and provide insights into node operations. He then served as a software engineer at BitGo, where he helped improve multisignature security services. These experiences gave him an intimate understanding of how Bitcoin security works at the protocol level, knowledge he would carry into his next venture.
In 2018, Lopp co-founded Casa alongside Jeremy Welch. Casa specializes in key management and self-custody solutions, offering a multi-key system designed to secure Bitcoin even if one key is compromised. The company's mission aligns perfectly with Lopp's core belief: that personal sovereignty requires personal custody, and personal custody requires excellent tooling.
Outside Casa, Lopp maintains lopp.net, widely regarded as the most comprehensive curated collection of Bitcoin resources on the internet. The site covers everything from technical documentation to economic theory, and it has become a default starting point for anyone serious about learning Bitcoin. His annual Bitcoin node performance tests and security audits are referenced across the industry.
In 2017, Lopp was the victim of a swatting incident that led him to take extreme measures to protect his personal privacy, including going completely off-grid in terms of public records. The New York Times profiled his efforts to erase his digital footprint. The experience reinforced his conviction that privacy is the outermost layer of security, and he now advocates relentlessly for operational security best practices in the Bitcoin community.
“Bitcoin is a hedge against the existing system. It's a way of opting out and saying there is a better way to do money and finance.”
