Drummond Reed 

At our 2024-06-26 meeting, we discussed the topic of "Identifier Traits" raised at DICE raised by Jan Christoph Ebersbach (known as "JC"). See this Github Gist page for a summary.

We agreed at that meeting that the TSPTF focus was on appraisability frameworks for dynamic appraisability of a VID, but that we would welcome work on a generalized set identifier traits that could feed into our appraisability framework.

Drummond will give a brief updated on the Identifier Traits work going to the DIF Identifiers and Discovery Working Group co-chaired by Markus Sabadello.

The slides Sam presented are here:

Some of the slides are also captures as screenshots #1 thru #9 below.

Sam's presentation covered a lot of background about KERI architecture in order to build up to showing a use case for how real-time appraisal of a VID can work using KERI, highlighting why dynamic appraisability is important and how it enables a validator to make a live appraisal thereby protecting themselves from a compromised or malicious controller.

In the Q&A, Sam clarified that key event logs (KELs) that use interaction events and key delegation are the ways that key management infrastructure can be scaled to millions of transactions in a short period.

Sam explained how the current bearer-token-based code signing used by companies by Microsoft is subject to (and has been) compromised by an attack on a bearer token. With KERI key management, the exact key that was compromised (and the exact key controller) can be identified and recovered.

Neil Thomson: "This suggests that on any interaction between VIDs (2 party) that they regularly perform a Live Assessment (e.g. once a day, every XX transactions)". Drummond agreed.
