Rockstar🎓
Top SchoolDave Longley is the founder and CTO of Digital Bazaar with over 20 years of experience designing Web-scale, decentralized systems that bridge identity, payments, and security. He is a principal architect of JSON-LD—a standard used by Google, Microsoft, Yahoo!, the BBC and hundreds of millions of users—and has driven W3C standards work on Web identity, payments, HTTP authentication, and secure messaging. A polyglot engineer comfortable in C, C++, Java, Python, C#, PHP and JavaScript, he has a track record of inventing high-performance primitives when infrastructure didn’t exist, including crypto and TLS integrations in prominent JSON-LD implementations. His cryptographic work has been used to secure a large share of binding online elections, and he has advised governance for self-sovereign identity through the Sovrin Foundation. Based in Blacksburg and grounded in a Computer Science degree from Virginia Tech, he combines deep standards leadership with hands-on open-source contributions to core JSON-LD libraries.
