Master Class: Digital Credentials Consortium
Sunday, April 5th, Room Three (123)

Kim is the Architect for the Decentralized Credentials Consortium (, which is a university-led effort to design a digital verifiable credentials infrastructure.

Kim is an expert and leader in the emerging decentralized identity space, driving standards and implementations through direct technical contributions and her leadership roles in the decentralized identity communities. She co-chairs the W3C Credentials Community Group, which incubated the Decentralized Identifier (DID) and Verifiable Credentials data models, and their ecosystem.

Kim co-created the Blockcerts open standard with the MIT Media Lab. This successful open source/standard project demonstrated decentralized verifiability of Open Badges by anchoring them to the Bitcoin blockchain.

Kim led development of the BTCR (Bitcoin Reference) DID Method — the first entirely open source/open standard DID Method. Unlike other DID methods, which are tied to fit-for-purpose blockchains, BTCR is a simple, easy to understand, and consequently trustworthy DID method. As a secondary effect, it’s been influential in the DID space for vetting DID as an interoperable standard and for pedagogical purposes.
