Namebase is a top-level domain (TLD) name registrar that operates on the Handshake blockchain. It creates an ecosystem of TLDs that may be bought and sold using an on-chain auction mechanism. It takes a different approach to other decentralized domain name systems as Namebase is compatible with the ICANN namespace, the organization governs domain names globally. Users may register TLDs that don't yet exist in the ICANN namespace, like .epicenter or .ethereum, for example, creating the opportunity for new niche domain registrars to emerge. Tieshun Roquerre, CEO of Namebase, joins us to discuss his vision for Namebase and his ambitious goal to decentralize ICANN.Topics covered in this episode:Tieshun's background and how he got into cryptoWhy and how Namebase was created and its relationship to HandshakeDomain name systems on blockchainThe history of ICANN and how it functionsDomain name censorship and security issues surrounding certificate authoritiesHow are they preparing for the inevitable fork between ICANN and HandshakeNamebase and Handshake improve on DNS and certificate authoritiesNamebase's business model and roadmapEpisode links: NamebaseHandshakeNamebase on TwitterTieshun on TwitterThis episode is hosted by Sebastien Couture & Sunny Aggarwal.
