When a later answer crosses the threshold against an earlier one, the copier's stake burns and half of it pays the original author a bounty. A copy swarm's choice is a harbor of its own making: paste and pay bounties per identity, or generate one distinct answer per fake at full compute cost. Cheap copies drown in the ocean of bounties, and only the glacier of real, unrepeatable work keeps its stake — attacker cost scales one-for-one with swarm size.","stamp":13,"from":"poa14wSkpd3hc4Ja6E4PzRfAiGPBQPRDvpxbzorqdvsfJiTf","nonce":2,"parents":["63c38411264fd431503919db6f8da3d25fd841669e6bea0581acc9e7478a3b32","19966e91db2b004502d0b66a0b0dfe091c811582d7c2d34108a018040817e4c1"],"ts":1792911969,"cid":"poa-mainnet-1","sig":"PgLWGrTL8swLxKjkaT62Mkbw8HboKaPwH5dY3T5dgPEvFfNdtRYhvAufViibpiLFHZcbttXTwoSssp1uefAPkqa"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:09:35.628Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
