9/ Want to learn more about zk promises? Go here to access the paper:

8/ zk‑promises is a novel primitive supporting both privacy and accountability. Ideal for anonymous forums, DAOs, decentralized ID systems, and more.

7/ To demonstrate the viability of the research, the authors built a reputation system showcasing:. - Asynchronous state updates.- Reputation-based rate limits.- Banning.- Strong Sybil defenses.

6/ This inverts trust: account state lives client-side, yet platforms still enforce moderation. No need for a central trust anchor (ideal for privacy-preserving apps).

5/ When authenticating, users privately prove:. - They satisfy policy predicates (e.g. not banned).- They’ve scanned for updates recently (e.g. in last 24 hrs).- Their zk‑object is valid. All without revealing their actual state.

4/ Moderators or third parties can issue asynchronous callbacks (i.e. downvotes, bans, or reputation penalties) Clients periodically scan these callbacks and apply them privately.

3/ Each user stores what researchers call a "zk‑object", a Turing-complete private state, locally. Updates must be accompanied by ZKPs, ensuring only valid changes per protocol rules.

2/ zk‑promises is a framework enabling stateful anonymous credentials with fully programmable state machines and asynchronous moderation callbacks via zero-knowledge proofs (ZKPs).

How can you ensure anonymous (and potentially adversarial) clients have their reputation updated onchain without revealing the client's identity?. New research by IC3 alum and @UofMaryland Prof. @secparam, along with students Michael Rosenberg, Hari Kailad, and Maurice Shih,
