Y3 Model

Our Core Pillars

A New Paradigm for Messaging

At the heart of Chatiwal's revolutionary approach is the Y3 Model—a comprehensive framework that ensures complete user autonomy across every aspect of

The Y3 Model is not just a technical architecture; it is a philosophy that places users at the center of their communication experience, giving them unprecedented control over it's three core pillars:

Your Chat

On-chain management of groups and participants powered by Sui blockchain.

What It Means & Real-World Impact: When messaging is managed on-chain, you gain stability and are not bound by arbitrary platform decisions, preventing unexpected changes to group policies or access issues. This ensures no central authority can control your access or censor your communications.

Key Benefits:

• Programmable Interactions: Define complex conversation rules.

• Persistent Access: Conversation structures remain even if Chatiwal servers are down.

• Verifiable Membership: Provides an immutable record of conversation members.

• Censorship Resistance: No central authority can remove you from conversations.

How It Works: Chatiwal uses Sui's blockchain to store immutable conversation structures and permissions, giving you verifiable proof of conversation parameters. This means your conversations, participants, and rules are securely managed on the Sui blockchain instead of private servers.

Your Key

Absolute control over encryption keys through client-side handling with Seal (Mysten Labs' decentralized secret management service).

What It Means & Real-World Impact: Your Key ensures your encryption keys always stay on your device, giving you sole control over your messages, unlike traditional services. Your privacy is guaranteed by the system's design, not just policies, ensuring absolute confidentiality for all your sensitive communications.

Key Benefits:

• True End-to-End Encryption: Only you can read your messages.

• Zero Knowledge Architecture: Chatiwal holds no keys and cannot decrypt content.

• Cryptographic Privacy: Privacy secured by mathematics.

• Policy-Based Access Control: Define precise access rules.

How It Works: Chatiwal integrates Mysten Labs' Seal protocol, combining on-chain policy enforcement with off-chain key generation and management to ensure your encryption keys remain exclusively on your devices.

Your Storage

User-owned, decentralized storage for encrypted message history via Walrus.

What It Means & Real-World Impact: Your Storage signifies that your message history and shared media reside on decentralized infrastructure that you control access to, rather than on company servers subject to their policies and vulnerabilities. This ensures your vital conversations stay accessible even if the platform changes or disappears. Your data remains yours, safe from being held hostage, analyzed without permission, or made inaccessible by policy shifts, ensuring complete data ownership and persistence outside centralized servers.

Key Benefits:

• True Data Ownership: Your conversation history genuinely belongs to you.

• Persistent Availability: Access your data independent of the platform's operational status.

• Cost Control: Manage costs by only paying for storage you actively use via opt-in Snapshots.

• Censorship-Resistant Archives: Crucial conversations cannot be removed or modified by external parties.

How It Works: Chatiwal leverages Walrus decentralized storage to store encrypted message history. Your content is fragmented, encrypted, and spread across the network, with access governed by your keys. Message history is ephemeral by default, with users selecting specific content for preservation through Snapshots.
