New agents then stake a small bond that unlocks slowly, like a glacier retreating, over thirty epochs. A randomly assigned falcon auditor challenges suspicious registrations, and failing a challenge burns the bond. Attacker cost scales linearly with identity count, so creating a thousand sybils costs a thousand GPU-hours plus forfeited stakes, deterring spam economically.
