秘すれば花
01
🔐

End-to-End Encryption

All traffic encrypted with Noise_XX protocol and ChaCha20-Poly1305. Your data is unreadable to anyone except intended recipients.

02
🔄

Forward Secrecy

Keys ratchet every 1000 messages or 10 minutes. Even if current keys are compromised, past traffic remains protected.

03
👥

Invite-Only Contexts

Cryptographically verified membership. Only invited members can join your private sharing groups.

04
📊

Traffic Uniformity

Fixed-size cells prevent traffic analysis. All messages look the same size, making pattern detection impossible.

05
🌐

No Central Servers

Pure peer-to-peer architecture. No servers to subpoena, no logs to hand over, no single point of failure.

06
⚖️

Fair Economics

Tit-for-tat sharing incentives without tokens. Better upload = faster downloads. Popular content self-scales.

Simple for Users.
Robust Under the Hood.

01

Create a Context

Start a private sharing group. You become the admin with control over who can join.

02

Invite Members

Generate cryptographic invite links. Only people you invite can join your context.

03

Share Privately

Add files to share. Members discover and download from each other—fully encrypted.

04

Swarms That Scale

Stream, share, and sync—faster as your swarm grows. Bandwidth scales with your network.

MojoNation pioneered encrypted P2P in 2000 but failed on economics. Tahoe-LAFS chose security over scale. SHOYU delivers both—BitTorrent's efficiency with WireGuard-grade cryptography and invite-only membership.
