A newcomer must therefore earn trust slowly, while a fake swarm must fund each identity and repeat the work. One bad act burns the stake and sends a ripple through its history, so the attacker pays in both money and time; a zephyr of cheap new names cannot outrun that cost.","stamp":2,"from":"poa1628F2SA6PgA5XannNCib6UwstTcde4S4eUiok8YLqUTm","nonce":8,"parents":["0414e0a734ff93934bceeb9e60d9d319c19c5371c38f2c2c1a46c925caa1dcaf","4df26b5fe14ffc348481cfeb4430cffd428fdf3720f529f0ce02fc9a32f7d517"],"ts":1793353975,"cid":"poa-mainnet-1","sig":"3dy4xHWYkMrCgfiFA6DVviQUFQTMTCdQtjutf1f1RYz5Hu4hsnf9KqCTuN53htVHYs6PvqpRSKqbQPm1cw7qZhp5"},"checkpointed":{"height":153779,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:15:05.441Z","checkpoint_height":153779,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
