Vision
Orbinum is a privacy-preserving blockchain built on Substrate, combining Zero-Knowledge proofs with EVM compatibility to enable confidential transactions without sacrificing auditability.

The Problem
Public blockchains expose all transaction data by design. This creates fundamental barriers for institutional adoption:
| Challenge | Impact |
|---|---|
| Transparent balances | Competitors can analyze holdings and strategies |
| Visible transactions | Front-running and MEV extraction |
| Public addresses | Privacy violations and targeted attacks |
| Compliance friction | Cannot satisfy both privacy and audit requirements |
The Solution
Orbinum implements Selective Privacy through a Shielded Pool architecture:
Key capabilities:
- Shield: Convert public tokens to private notes
- Private Transfer: Move value without revealing sender, recipient, or amount
- Unshield: Convert private notes back to public tokens
- Selective Disclosure: Grant view access to authorized parties
Core Principles
Privacy by Default
Transactions in the shielded pool are confidential. No metadata leakage.
Programmable Auditability
View keys enable compliance without compromising user privacy.
Cryptographic Security
Groth16 proofs on BN254 curve with sub-10ms verification.
