👣 Multi-Phase Dispute Resolution

The opML-inspired system introduces layered verification:

1️⃣ Phase 1: Coarse bisection of state transitions
2️⃣Phase 2: Instruction-level verification
🦥Lazy loading: Optimized memory use

🏆 DAVE-Inspired Tournament Logic

Parallel, permissionless challenge games evolve through structured rounds with:

⚔️ Hierarchical match progression
⚙️Cross-VM trace support (MIPS + RISC-V)
🎲Game-theoretic incentives

We implemented two complementary mechanisms:

👣 Multi-phase resolution (inspired on opML)
⚔️ Tournament disputes (inspired on DAVE)

Both sit atop 🔴✨Optimism’s Canon FPVM.
