Orina Protocol - Hybrid settlement rails for programmable commerce

I built Orina around a simple belief: commerce is not only a discovery problem. It is a settlement problem. Marketplaces, AI tools, logistics systems, and payment rails can improve coordination, but transactions still need clear authority, bounded execution, escrow, dispute paths, timeouts, and final state. Orina Protocol approaches this as hybrid infrastructure. It does not try to turn every part of commerce into a crypto experience. Instead, it uses blockchain only where the properties are useful: verifiable signatures, escrow isolation, lifecycle state, receipt finalization, and auditable settlement outcomes. The core protocol is ATP, the Atomic Transaction Protocol. ATP models commerce as a state machine: Intent -> Authorized Action -> Bounded Execution -> Finalized Settlement State. This matters for real-world asset commerce and future autonomous transactions, where software may help generate intent or execute within limits, but software should not become unconstrained settlement authority. I am sharing Orina on Product Hunt to connect with builders, commerce operators, RWA teams, and infrastructure-minded people who care about making real transactions more explicit, auditable, and reliable.
