Privacy Oracle
The Chainlink of Privacy — a cross-chain network for processing encrypted data.
The Problem
Why Privacy Matters
Blockchains are public by default:
- Send 100 tokens → Everyone sees you sent 100 tokens
- Check your balance → Everyone sees your balance
- Trade on a DEX → Front-runners see your order before it executes
- Run a business → Competitors track every transaction you make
Building privacy yourself means:
- Learning complex cryptography (FHE, ZKP, MPC...)
- Writing and auditing circuits
- Managing keys and infrastructure
- Solving scalability bottlenecks
- Building chain-specific implementations
- Months of development before you can start
Privacy Oracle abstracts all of this. You encrypt locally, submit to the decentralized network — or run your own infrastructure — and get encrypted results back. The cryptographic complexity is handled, across any chain.
The Solution
Process Transactions Without Exposing Data
Privacy Oracle enables you to:
- Transfer funds without revealing amounts
- Settle between parties without intermediaries seeing details
- Prove compliance without exposing underlying data
- Maintain confidentiality while meeting regulatory requirements
In one sentence: Your data stays encrypted throughout. Computation happens on ciphertext — the actual values are never exposed.
The Technology
FHE — Fully Homomorphic Encryption
Perform mathematical operations on encrypted data without decrypting it. The result is also encrypted — only the key holder can read it.
Status: Early Access
ZKP — Zero-Knowledge Proofs
Prove that a statement is true without revealing any underlying data. Verify computation correctness without exposing inputs or outputs.
Status: Coming soon
Key Benefits
| Benefit | What It Means |
|---|---|
| Mathematical guarantee | Not "trust us" — it's cryptographic proof |
| No data exposure | Processing happens on encrypted values |
| Audit-ready | Prove correctness without compromising privacy |
| Framework compatible | Works with existing compliance requirements |
How It Works
1. You encrypt your data locally (keys stay with you)
2. Submit encrypted request to any supported blockchain
3. The network processes it — data stays encrypted throughout
4. Encrypted result posted back on-chain
5. Only you can decrypt (no one else has the keys)
Key Point: Your encryption keys never leave your systems. Only ciphertext is ever exposed.
Use Cases
Cross-Border Payments
Bank A sends to Bank B through intermediaries. The intermediaries process the payment but cannot see the amount or the parties involved. Settlement happens privately.
Confidential Token Transfers
Move assets between accounts without revealing balances or transfer amounts. Perfect for institutional trading desks, treasury operations, and inter-entity transfers.
Private Voting & Governance
Shareholders vote on proposals. Votes are tallied without anyone seeing individual choices. The final result is mathematically verifiable.
Regulatory Compliance with Privacy
Run AML/KYC checks on encrypted data. Pass compliance requirements without exposing customer details to processors or intermediaries.
Selective Disclosure
Privacy AND Compliance
When regulators or auditors require access:
- Data stays encrypted on-chain (normal operation)
- Reveal ONLY specific fields — e.g., show amount but not parties
- Auditor gets limited access — their key only decrypts what's authorized
- Full audit trail — without full exposure
You control what gets disclosed, to whom, and when.
| Scenario | What Auditor Sees | What Stays Private |
|---|---|---|
| AML check | Transaction amount | Sender, receiver identity |
| Balance audit | Account balance | Transaction history |
| Compliance report | Aggregate volumes | Individual transactions |
Deployment Options
| Option | Best For | Description |
|---|---|---|
| Decentralized Network | Public applications | Open operators, trustless, permissionless |
| Dedicated Infrastructure | Banks & enterprises | On-prem, VPC, or managed service with SLAs |
Enterprise deployment includes:
- Private infrastructure (your cloud or on-premise)
- Service level agreements
- Dedicated support
- Custom compliance configurations
Why Trust This?
Not "trust us" — it's math.
You hold the secret key. Without it, decryption is mathematically impossible — not prohibited by policy, impossible by cryptography.
Computation happens on ciphertext. Whether on the public network or your own infrastructure, data stays encrypted throughout processing. Even if compromised, your data stays private.
Everything is verifiable. Prove computation was done correctly without revealing inputs or outputs. Mathematical proof, not promises.
The blockchain only stores ciphertext. Encrypted blobs that no one can read without your key.
No trusted third party. No hardware assumptions. Pure cryptography.
Works Everywhere
Same encrypted data works across all supported chains:
- Solana — Native program integration
- StarkNet — Cairo contract support
- XRPL — Hooks integration
- Tron — TVM contract support
- EVM — Public and permissioned chains
Encrypt once, use anywhere. The same encrypted payload (CID) works on any chain.
