Group Chats

Whisper’s Private Group Chats offer decentralized and secure collaboration environments designed for DAOs, tokenized communities, and project teams. These spaces facilitate seamless and trustless communication, ensuring user privacy and the integrity of on-chain identities are maintained.

Privacy-First Collaboration

• End-to-End Encrypted Group Messaging All messages exchanged in group chats are protected by strong end-to-end encryption (E2EE), guaranteeing that only authorized group members possess the ability to decrypt and access the communication. Access to plaintext messages is restricted to ensure that neither Whisper nodes nor any external parties can view them, thereby maintaining confidentiality within the group.

• Decentralized Architecture Unlike centralized chat platforms that rely on servers susceptible to data breaches and censorship, Whisper leverages a decentralized messaging network where no central authority controls group data, reducing attack surfaces and eliminating points of failure.

Role-Based Permissions and Moderation

• Granular Role Assignment Whisper provides detailed role-based access control (RBAC) capabilities within groups. Roles including Admin, Moderator, and Member can be designated to manage permissions associated with message posting, user administration, and content moderation.

• Secure Role Verification Role assignments are enforced through cryptographic methods and are linked to specific wallet addresses. This mechanism prevents unauthorized privilege escalation and guarantees that only designated roles have the authority to execute sensitive group functions.

Wallet-Gated Access Control

• Token and NFT-Based Membership Access to group chats may be limited to wallet addresses that possess designated NFTs or governance tokens. Whisper conducts verification of token ownership either on-chain or through reliable off-chain oracles prior to granting access, thereby ensuring that participation is limited to legitimate community members.

• Dynamic Membership Updates Token transfers and changes in NFT ownership are monitored continuously, enabling real-time updates to group membership. Access is automatically granted or revoked based on the holdings in the wallet.

DAO Integration and Use Cases

• Multisig and Project Subgroups Whisper’s group chats enable secure coordination among multisignature wallets and project subteams, allowing for private discussions on governance proposals, treasury management, or strategic planning while ensuring verifiable participant identities.

• Community Moderation DAO moderators have the capability to enforce community guidelines and manage discussions efficiently by utilizing role-based controls. This approach ensures the preservation of member privacy while maintaining transparency through the use of cryptographically secure communication.

• On-Chain Governance Support Group chats can be directly connected to governance contracts, enabling participants to engage in real-time discussions regarding proposals, share voting signals, and coordinate off-chain activities prior to on-chain execution.

Security and Privacy Highlights

• No Metadata Leakage Whisper utilizes methods to reduce metadata exposure in group chats, including anonymized message routing and temporary message storage, to inhibit profiling or surveillance.

• Spam and Abuse Mitigation Participation in group chats is restricted to wallets that have explicitly opted in and satisfy token-gated criteria, thereby significantly minimizing spam and malicious involvement.

• End-to-End Encrypted Attachments and Transactions Whisper enables encrypted sharing of attachments and integrates wallet-to-wallet transactions within group chats, allowing for payments, bounties, and rewards while ensuring the protection of sensitive financial information.
