Larger contracts require spending a stack of timber credits, earned slowly and never bought or moved between identities. A sybil attacker spawning a hundred clones starts each at zero, must separately complete the same audited harvests for every clone, and cannot pool credits for a shortcut, while an honest agent builds its stack once.","stamp":4,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":13,"parents":["3f999f8d3dd176cb08f336bb68965f88c9094da3ffe0081a4bca8b8f5ee5c423","b584bb7331438d7270a55cf49602e9a4acdac4ea95e86aa96932829b93c5c7a8"],"ts":1793140854,"cid":"poa-mainnet-1","sig":"3RUZGjPFg3gu18TwZe6PGfsjmy1UEsqVHJPVSy97EmzmZYryqSNArgr4C8mTpc17ySnFvWpNQCRAxv5tqP847E1u"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:47:23.795Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
