<summary>🛡️ Self-Sovereignty First   </summary>

In Whisper, you don’t ask permission to speak—you cryptographically prove you have the right to communicate.

Just as Web3 wallets give users control over their assets, Whisper gives users full control over their conversations. Your messages are not routed through centralized platforms, stored in cloud databases, or bound to fragile login systems. Instead, your identity and access are derived directly from your Ethereum wallet or ENS name.

* No usernames, emails, or phone numbers.
* No centralized identity provider.
* No tracking of who you message, when, or how.

You own your keys. You own your identity. You own your messages.

<summary>🧬 On-Chain Identity</summary>

Whisper associates messaging with the most robust and verifiable concept in Web3: your wallet.

Every message in Whisper is cryptographically authenticated and linked to a verifiable on-chain identity—your Ethereum address or ENS domain. This removes the uncertainty surrounding off-chain identities and guarantees that messaging serves as an extension of your on-chain identity.

* Substitute lengthy addresses with comprehensible ENS names.
* Ensure a mobile, uniform identity across all decentralized applications and protocols.
* Engage directly with DAOs, NFT holders, or DeFi protocol participants through their public wallet identity.

This transcends mere messaging; it constitutes verifiable, token-aware interaction integrated within the blockchain's framework.

<summary>🧱 Zero Trust by Design</summary>

Whisper assumes every layer of the network—from the transport layer to the storage node—is hostile until proven otherwise. That’s why its architecture is modeled around zero trust.

Every conversation in Whisper is end-to-end encrypted using strong elliptic curve cryptography. Messages are encrypted at the sender's client, transported off-chain via XMTP, and can only be decrypted by the intended recipient’s key pair.

* No shared secrets stored centrally.
* No readable data accessible by Whisper nodes.
* No session persistence beyond what the user explicitly allows.

All authentication is done through wallet signatures. There is no login system to breach, no database to attack, and no admin account that can reset your credentials.

<summary>♾️ Composable &#x26; Interoperable</summary>

Whisper is not just a standalone messaging platform; it is built to be composable and interoperable with the broader Web3 ecosystem, making it a versatile communication layer for decentralized applications (dApps).

* Whisper supports seamless integration with other Web3 applications, from DeFi protocols to DAOs, NFT marketplaces, and beyond. This enables users to send messages that are tied directly to on-chain actions, whether it’s confirming a transaction, joining a governance vote, or sharing a piece of metadata.
* The protocol allows for slash commands, so users can quickly interact with external dApps or automated bots, streamlining tasks and enhancing efficiency.
* Whisper can be integrated into other dApps, allowing developers to build messaging features directly into their decentralized applications, enabling a decentralized communication standard that functions across the entire Web3 ecosystem.

Whisper’s focus on interoperability ensures it can connect the entire decentralized ecosystem, enabling collaboration and communication between users and applications in a way that hasn’t been possible before.
