Proof Chain (L3)
Dedicated Madara L3 appchain for zero-gas proof verification and fact settlement.
What it does
The Obsqra Proof Chain is a Madara-based Starknet L3 sequencer dedicated to proof-fact registration, on-chain verification via Garaga and Integrity verifiers, and batched settlement to Starknet L2. 5-second blocks, zero gas, 3 proving paths.
Current capabilities
- • Live block production at 5s cadence with zero-gas fee model.
- • Groth16 on-chain verification via Garaga (31 circuits).
- • STARK on-chain verification via Integrity (6 programs).
- • Hash-only fallback with circuit breaker for emergency ops.
- • L3 → L2 state-diff settlement with validity proofs.
- • Public RPC, block explorer, and wallet add-network support.
Standalone API Sandbox
