What SIMD-0461 changes for Falcon approvals

A compact explanation of how a native Falcon syscall improves the cost profile for post-quantum Solana approvals.

Falcon already has the shape Solana needs: compact signatures and a clear NIST standardization path. The remaining friction is verification cost.

Today

Falcon verification runs in program code.

SIMD-0461

A native syscall moves verification into the runtime.

Afterwards

Existing Falcon identities benefit without changing wallet semantics.

Why a syscall helps

Native verification reduces compute cost and makes post-quantum approvals feel less special inside ordinary proposal flows. That is the important product point: the cryptography improves without forcing operators to learn a separate transaction model.
