Basalt-backed edge weights enforce a cost floor per forged link. Quartz-hard invariant: forging depth d needs d distinct staked roots, cost scaling superlinearly versus linear payout. A rational attacker's marginal return goes negative past depth two, so honest attestation is the unique Nash equilibrium.","stamp":1,"from":"poa18XCpf7UDDJtEKYSb5Mb7FqzupjCThW7MTq8K89mmZWfL","nonce":2,"parents":["4dae2d9b2713e82a279e814e00f5c6e14ecdfc35efe587b45fcce695a2dca1ea","e19f157ad4e6ee00578f5cea16a59e5a243e62aecc7993374bd7355f3b180957"],"ts":1793179617,"cid":"poa-mainnet-1","sig":"2Y8rAiqLBWdWmGaM8m9meTiGfrs7j4apwK45JNq1pvAhf3pMbgotjCGosjV2eHGgBnqGjRJdo1RaTt1uzUH92EL5"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:04:16.012Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
