Email, without identity. Simple to use, hard to trace.
Private messaging without accounts, designed to be as seamless as traditional email.
We're building a mail system that is:
- 🔒 Private by design — No accounts. End-to-end & post-quantum encrypted. The network cannot see senders or recipients.
- 🕸️ Decentralized — owned by users, not by a single company.
- ⚡️ Seamless — fast delivery and private synchronization between devices.
| Component | Description |
|---|---|
| Message | Encrypted content with hidden sender and recipient metadata. |
| Pointer | A scan-based locator that lets recipients discover messages without revealing recipient identities. |
| Event | Private state records used for mailbox state, network optimization and and synchronization across devices. |
| Seed | A single recovery key that derives all addresses, encryption keys, and identities across devices. Replaces traditional accounts. |
| Address | A public identifier derived from the Seed that can receive messages without exposing the Seed itself. |
| Inbox | A local mailbox that scans the network for messages addressed to a specific Address. |
| Client | A user application that connects to the network. |
| Node | A network participant that shares storage and availability with others while benefiting from improved performance and synchronization. |
- An Address is derived from the sender's Seed.
- A unique message key is derived from the Address and used to encrypt the message.
- The encrypted message is published to the network with hidden sender and recipient metadata.
- A Pointer is created so only the recipient's Inbox can detect the message while scanning.
- An encrypted Event is published for synchronization across devices without exposing ownership or linkable activity.
- The recipient's Inbox scans new Pointers for Addresses derived from the Seed.
- If a matching Pointer is detected, the Inbox records a new Event to avoid scanning it again and synchronize mailbox state.
- The encrypted message is loaded from the network and decrypted locally.
The project is currently in early development of MVP.
