Smith presents KERI as a ledgerless decentralized key management infrastructure and a secure identifier overlay for the internet. The page carries an embedded YouTube video and links to the slides, under a Creative Commons BY-SA 4.0 license, and suits newcomers who want the 2020 introduction from the author. ## Summary This item is a recorded webinar, number 58 in the SSIMeetup series, posted on 19 May 2020. The summary below rests only on the event page; the video itself was not watched, so it describes what the page says the talk covers rather than the talk. The page introduces the presenter, Samuel M. Smith, as an entrepreneur and strategic consultant at the intersection of artificial intelligence, blockchain and decentralized computing, formerly a full professor at Florida Atlantic University. It describes KERI (Key Event Receipt Infrastructure) as a ledger-less approach to identity that provides a decentralized key management infrastructure. According to the page, KERI rests on two roots of trust: self-certifying identifiers, which are bound at issuance to cryptographic key pairs, and end-verifiable key event receipt logs (KERLs), which record changes of control. The page presents KERI as a candidate to replace the Domain Name System and certificate authority system (DNS-CA) as a trust spanning layer for the internet, describes its identifiers as portable and self-sovereign, and says it is the basis for a proposed universal DID (decentralized identifier) method named "DID:uni". At the time, the page notes, KERI was an open-source project within the Decentralized Identity Foundation (DIF). The page links slides on SlideShare and Google Slides and embeds the YouTube recording, and it releases the content under a Creative Commons Attribution-ShareAlike 4.0 license crediting SSIMeetup and the guest. The talk's title matches the title of the overview deck that keri.one lists as the KERI White Paper Slide Deck. ## Key terms self-certifying identifier, key event receipt log (KERL), end-verifiable, decentralized key management infrastructure, trust spanning layer, DNS-CA, DID:uni ## Claims and their evidence - KERI provides a ledger-less decentralized key management infrastructure (page description).
