The method did:ion began as an exercise in scalability. Backed by Microsoft, did:ion is a layer 2 “identity” network built on top of bitcoin that promises the security of the world’s oldest and largest cryptocurrency with radically lower cost and higher throughput. We talk with Daniel Buchner of Microsoft, the creator of the Sidetree protocol...

did:snail is hands-down the most innovative DID method we know of. It connects the world’s most modern identification architecture with the oldest, most widely adopted long distance communications channel known to man, the international postal system. Join us for a talk with Amy Guy, did:snail creator, and  Dmitri Zagidulin, a co-author of the did:snail specification,...

did:ethr brings decentralized identifiers to Ethereum, the world’s second largest cryptocurrency network. Early contributors to the DID conversation, the folks behind did:ethr helped establish several innovations that significantly improve the cost-effectiveness and usability of crypto-currency-based identifiers. We speak with Oliver Terbu and Mircea Nestor, editors of the did:ethr specification to understand the motivations behind the...

IPID is the DID method based on IPFS, the Interplanetary File System, the leading decentralized file storage system. Using IPFS as its verifiable data registry, IPID doesn’t rely on a blockchain. Instead, it provides a simple and convenient way to use IPFS to resolve an IPID DID to its current DID Document. We talk with...

[Part 2 of 2] We talk with Orie Steele of Transmute, an editor of the did:key spec and Mike Varley of SecureKey, who has worked through that spec and implemented did:key for his company. did:key might be the simplest and most useful DID method out there. It certainly was the most surprising when we first learned...

[Part 2 of 2] Veres One is the progenitor DID Method. Before BTCR, before DIDs were even called Decentralized Identifiers, Manu Sporny and the team at Digital Bazaar created a ledger-based identifier architecture using their own fit-for-purpose non-cryptocurrency blockchain called Veres One. We talk with Manu about Veres One, the state of the DID ecosystem,...
