Submission: LP-0016 — Anonymous Forum with Threshold Moderation and Membership Revocation

Submitted by: Syafiq (Evice Labs)

Implementation PR: logos-blockchain/logos-execution-zone#465

Summary

A complete implementation of the LP-0016 protocol built on the Logos Execution Zone (LEZ).
Members post anonymously via ZK proofs, moderators issue strikes through N-of-M threshold
consensus, and K accumulated strikes cryptographically reconstruct the member's Nullifier
Secret Key — enabling on-chain slashing and retroactive deanonymization of all prior posts.

Deliverables

• LEZ Program — membership_registry via SPEL framework with per-instance forum_id
  PDA, supporting multiple independent forum instances from a single deployment
• ZK Circuit — forum_membership_proof proving inclusion, non-revocation, and tracing
  tag integrity without revealing the poster's identity
• Moderation Library — logos_moderation_sdk: forum-agnostic, operates on abstract
  byte identifiers, exposed as WASM bindings for browser use
• Basecamp App — Full lifecycle UI: registration, anonymous posting, N-of-M moderation,
  strike accumulation, and cryptographic slashing
• Two Forum Instances — K=2/N=2-of-3 and K=3/N=3-of-5, independently parameterised
• Protocol Spec — docs/protocol.md: formal unlinkability proofs, retroactive
  deanonymization analysis, N-of-M trust model, and threat model
• IDL — Generated via SPEL CLI, machine-readable interface for all 4 instructions

Hi! thank you for the submission.

Note that "Logos Basecamp" mean it's an for https://github.com/logos-co/logos-basecamp/

Doc on how to build said app (aka ui and core module) can be found here: logos-co/logos-docs#227

Thanks for the clarification, @fryorcraken. I just realized this earlier today. Already deep dive into logos-basecamp to understand the architecture comprehensively. Hope my next submission will be fully align with the logos ecosystem.
