Path to Privacy Standard
SIP Protocol is building the privacy standard for Web3 — like HTTPS for the internet. 22 milestones across 5 phases. 15 milestones complete.

Standard Proposal
SIP-EIP formal specification, industry working group formation
Viewing key APIs for Fireblocks, Anchorage, BitGo, Coinbase Prime
Cryptographic Privacy vs Pool Mixing
SIP uses Pedersen commitments and stealth addresses — cryptographic privacy, not statistical anonymity from pool mixing.
| Feature | PrivacyCash | Tornado Cash | Railgun | SIP Protocol |
|---|---|---|---|---|
| Chain Support | Solana only | ETH only | ETH only | Multi-chain |
| Privacy Method | Pool mixing | Pool mixing | ZK shielded | Cryptographic (Pedersen + Stealth) |
| Amount Hidden | ||||
| Viewing Keys | ||||
| Cross-Chain | ||||
| Amount Correlation | Vulnerable | Vulnerable | Partial | Protected |
| Regulatory Risk | HIGH | HIGH | HIGH | LOW |
Amount Correlation Attack
Even when a mixer supports arbitrary amounts, if amounts are VISIBLE on-chain, they can be correlated. If Alice deposits 1.337 SOL (unique amount), tracking that withdrawal is trivial. SIP hides amounts via Pedersen commitments - on-chain observers see only opaque cryptographic points.
SIP Advantage: Cryptographic privacy, not statistical
The Endgame
“SIP is to privacy what HTTPS is to the web”
Privacy middleware between applications and blockchains. Chain-agnostic. Settlement-agnostic. One toggle to shield any transaction. The universal privacy standard for Web3.
