KERI: Key Event Registry Infrastructure
"KERI is the first truly decentralized identity system. It is ledger-less, so it doesn't need to use a ledger or is ledger-portable. Its identifiers are not locked to any given ledger and may switch as needed. In other words, KERI identifiers are genuinely portable.
KERI is inherently supportive of GDPR (global data protection rights) compliance. KERI provides non-intertwined identifier trust bases, meaning that a given identifier's data may be erased and truly forgotten.
KERI has a decentralized, secure root-of-trust based on cryptographic self-certifying identifiers. It has separable control over shared data which means each entity is truly self-sovereign over its identifiers. It uses hash-chained data structures called Key Event Logs that enable ambient cryptographic verifiability. In other words, any log may be verified anywhere at anytime by anybody."

CESR Proof Signatures are the “Segwit” of Authentic Data in KERI.
KERI.DotNet
I am particularly interested in the Rust implementation of KERI. It would be great if we could put a DotNet wrapper around that library. Thoughts?
There is a great deal of information out there on KERI, so let's give a summary of key insights.
How Does KERI Differ From a Blockchain?
There is a lot of information out there on KERI, and it may be difficult to grasp the key innovation. So here is representation of the possible element/requirements in the SSI/Blockchain "Trade Space":
KERI Does not require:
- Total Ordering because only the Controller (of the key pair) can order its events
- Crypto-currrency to implement an Identity System
- Shared control, because there is only one controller for the KERI log
- Locked to a ledger
