This week on The Polyhedra Show, @Tony0kai sat down with our co-founder @Tiancheng_Xie (TC) to break down the launch of @opencash_system - Polyhedra’s private, compliant financial layer for the on-chain world. Some key takeaways:

1/ What it is: On-chain money is already here. Stablecoins processed $4T+ in 2025 alone. But today, users and enterprises face a dead-end choice: • Fully transparent (your entire financial history exposed) • Fully anonymous (impossible for regulators to accept) Ocash introduces a new rail: Private by default. Auditable on subpoena. Powered by zero-knowledge proofs. A selective-disclosure engine, not a “hide everything forever” mixer.

2/ Why it matters: • Stablecoins now exceed Visa + Mastercard volume combined • Enterprises cannot run treasury, payroll, or supply-chain logic on a public ledger • Regulators (GENIUS Act, MiCA) now require auditability, not surveillance • The world needs cash-like privacy and compliance built into the rail Ocash enables: ✓ Private, compliant transactions ✓ Regulator-ready audit proofs via Dual-Key Escrow ✓ Private payroll for DAOs & enterprises ✓ Remittance rails targeting ~1% fees ✓ A unified settlement layer for humans and autonomous AI agents
