THE PROBLEM

Transparency Has Become
a Strategic Liability

In 2026, every on-chain transaction is a public data point. Payrolls, treasury movements, corporate strategies — all exposed. Solana won the speed war, but absolute visibility is the cost.

01
👁
EXPOSED TREASURIES
Any entity paying suppliers or employees on-chain exposes their entire financial structure to competitors and adversaries.
THREAT LEVEL: CRITICAL
02
🎯
MEV EXPLOITATION
Public mempools allow front-running bots to extract value from every large transaction before it reaches finality.
THREAT LEVEL: HIGH
03
🔗
TRANSACTION LINKABILITY
Pattern analysis can reconstruct entire financial histories, destroying the privacy of individuals and institutions alike.
THREAT LEVEL: HIGH
04
⚖️
COMPLIANCE GAP
Existing privacy tools ignore compliance. Institutions need privacy AND audit capability — not one without the other.
THREAT LEVEL: CRITICAL
THE SOLUTION

The Grey Space:
Privacy Meets Compliance

$NORTH occupies the Grey Space — privacy by default, governance by design. Built for institutions that require confidentiality, control, and provable oversight.

PROTOCOL 01
SENTINEL
The core program deployed on Solana with 16 instructions. Rails, handshakes, encrypted vaults, strict authority constraints, and multi-asset VaultAssetState accounting for SOL and SPL flows.
  • Privacy Rails with compliance controls
  • ZK Handshakes with nullifier registry
  • Encrypted vaults (ElGamal)
  • Groth16-verified deposits & withdrawals
  • NORTH token gate for authority
PROTOCOL 02
ZK ENGINE
Groth16 zero-knowledge proof system. 3 circuits for deposit, withdraw, and transfer. On-chain verification via Solana alt_bn128 precompiles.
  • Groth16 SNARK proof generation
  • 3 circom circuits (deposit/withdraw/transfer)
  • On-chain verifier (alt_bn128)
  • ElGamal encrypted balances
  • Anti double-spend (nullifiers)
PROTOCOL 03
SILENT RAILS
Institutional-grade control layer. Pause, seal, and deactivate rails with deterministic policy paths, incident-response controls, and forensic-grade audit trail compatibility.
  • Rail pause / unpause controls
  • Immutable audit seals
  • Permanent deactivation
  • Reason codes for compliance
  • 19 on-chain error types
