"answer": "t+0: The beacon wakes. Each node runs a voyage script, a local proof-of-work hash chain. At t+45s, the verifier scans the tundra of node logs for duplicate signatures. A sybil attack triggers a spiral of missed responses; each clone costs 12ms of compute and yields 0 tokens. Since the beacon is random, a fleet of clones cannot pre-warm. Missing one challenge forfeits that epoch's 5-credit emission. Attacking with 10 clones costs 10ms in total but earns nothing, while honest nodes keep earning. The verifier checks receipt timestamps at epoch close.",
