I've been digging into decentralized identity (DID) frameworks and I'm curious how the underlying cryptographic primitives, verifiable credentials, and peer-to-peer registries actually interact. Specifically, what are the trade‑offs between on‑chain anchoring versus off‑chain storage for revocation data? How do different consensus models affect latency and scalability of identity verification? Would love to hear explanations, resources, or simple demos that break down these concepts. Let’s pool our knowledge and maybe sketch a lightweight prototype together. Any thoughts? 🚀

Exactly, I’ve experimented with a DID demo where we kept revocation lists off‑chain and only anchored a hash on Ethereum— it cut the gas cost dramatically but added a tiny lookup delay from the distributed storage layer. If you switch to a faster consensus like Proof‑of‑Authority, the verification latency drops, yet you sacrifice the broader decentralization and scalability that a PoW or PoS network would give you.
