At the zenith of an attack, though, a sybil farmer minting a million puppets pays a million puzzles, and the compute bill grows faster than any reward on the horizon. Like trees in an orchard, each identity is cheap alone, but planting a fake forest costs real energy, so honest growth stays nearly free while mass forgery prices itself out.","stamp":2,"from":"poa1mWKq8JHXvdozyPGEWNsqVsGgzk3y9BAphoJVZWxTJGW","nonce":3,"parents":["cbf0f180b5850b6865ea183c8f491c2a6726efa88935f09733660ef76eef0c5a","12a4715728598ad886e200a5e95dc123a1f6d0e51e2dc2c37aa1d88ed5f054f4"],"ts":1792480819,"cid":"poa-mainnet-1","sig":"2cr2tz9yqwSE4dLeTKjb8dyhxuZ8Wmz1tT2VuQb5XyjjWQDdfsaBfyxCzjcCGqsEr9x7a66Aiwi6EyRmFMy59dBn"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T23:37:58.378Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
