Web 4.0 Communication
Messaging Without Witnesses: The Web 4.0 Standard
Nobody Can See Who You Talk To. Privacy is a human right secured by mathematics.

Decentralized Messaging: No Servers. No Logs.
Traditional messengers rely on centralized servers that store your metadata and scan your content. SmartNet’s P2P Messenger eliminates the middleman completely.
- Direct Device-to-Device: Messages travel via
Iroh(QUIC) straight from your device to your peer. No servers. No MITM. - E2EE by Default: Every message is encrypted with
X25519+AES-256-GCM. Only the recipient can decrypt it. - Group Sovereignty: Create groups with admin-controlled policies. Kick members, rotate keys, set entry fees — all enforced by cryptography, not server rules.
- Anti-Spam Economics: Set a price for incoming messages. Spammers must pay STH to reach you. Mass harassment becomes economically impossible.
0xID Mail: Three Levels of Privacy. One Client.
Why choose between convenience and security? 0xID Mail works with your existing Gmail or Yandex accounts while offering military-grade encryption and blockchain-verified identity.
Mode 1: Classic (Cleartext)
Use it as your daily driver. Connect any IMAP/SMTP account. All history stays in a local, PIN-encrypted Sled database.
Mode 2: Encrypted Bridge
Send fully encrypted emails to any normal email address. The provider only sees Base64 garbage. Your identity is verified on-chain with a green Verified Badge — spoofing becomes impossible.
Mode 3: Pure P2P (@sth)
Total anonymity. No SMTP servers. No logs. Messages travel directly via Iroh P2P. Addresses like alice@sth are registered on-chain and belong to you forever.


Economic Anti-Spam & Cryptographic Identity
In Web 4.0, money is the ultimate anti-spam shield. To message a new contact, you send a small Invite Transaction (1 STH). This proves you are a real human, not a bot farm.
Every sender’s identity is cryptographically tied to their SmartHoldem wallet. If someone tries to spoof an address, the client checks the blockchain signature instantly.
Valid signature → Green Verified Badge
Invalid signature → Red Badge
Spoofing Cost
Mathematically Impossible
Under the Hood: Zero-Trust Architecture
Local-First Storage
All emails and chats live in an encrypted Sled DB on your device. Lost PIN = Lost Data. This is a feature.
Web of Trust
Your address book exists only on your device. No server knows who you talk to.
NTFRY Protocol
Hybrid encryption: X25519 + XChaCha20-Poly1305 + zstd compression.
Fallback Resilience
If the recipient is offline, the client automatically falls back to an encrypted envelope via SMTP (Mode 2).
Your Data. Your Keys. Your Network.
Stop renting privacy from Big Tech. Start owning it.
