eCloakCore

Built by Evice Labs

eCloak Core C++ Qt Plugin Engine for Logos Basecamp, bridging the E-Identity Stack (e_identity_sdk and e_moderation_sdk) to the Basecamp QML frontend via C-ABI FFI.

Architectural Overview

el-anon-chat-core () implements the PluginInterface and exposes AnonChatInterface to Basecamp, providing native cryptographic capabilities:

1. Identity Management:

   • Random and deterministic Nullifier Secret Key (NSK) derivation.
   • Commitment computation: SHA256(NSK).
   • Off-chain username registry with Schnorr signature authentication.

2. Decentralized Room Management:

   • Deterministic room creation (SHA256(admin_commitment || creation_index || n_mod || m_mod)).
   • Cryptographically signed join-consent requests.
   • Room maturity validation (age indexes and active member tracking).

3. Two-Tier Shamir Secret Sharing (SSS) Chat Messaging:

   • MemberClient integration: creates post payloads with Tier-2 point assignment.
   • Tier-1 N-of-M splitting per post.
   • Diffie-Hellman (ECDH) encryption of secret shares targeted at individual moderator public keys.

4. Moderator Strike Protocol:

   • ModeratorClient share decryption using secp256k1 private keys.
   • BIP-340 Schnorr strike certification.
   • Multi-signature certificate validation.

5. Lagrange Slashing & Identity De-Anonymization:

   • Tier-1 strike reconstruction from N moderator shares over GF(2⁸).
   • Tier-2 full NSK reconstruction from K accumulated strikes.
   • Identity commitment blacklisting.
