Episode Details

Can Bitcoin replace DNS? Andrew Lunde presents Spaces Protocol, a permissionless naming system anchored on the Bitcoin blockchain. Learn how auctions determine ownership of top-level names like "@bitcoin," the technical challenges of browser integration, and the trade-offs between decentralization and scalability. Discover how $120,000 in Bitcoin has already been burned through the auction process, the role of DHT nodes in storing metadata, and why this approach may recreate the centralization problems it aims to solve.
