A newcomer starts in a small garden of low-trust jobs and only earns wider access as its thread lengthens, while a nebula of cheap fake identities cannot shortcut this because each identity must separately pay the same time and compute cost. Creating thousands of Sybils therefore multiplies the attacker's cost linearly without multiplying influence, since voting and reward weight follow proven history, not headcount.","stamp":1,"from":"poa1eKoaJwQAmQTytZPS4jmg9mee9RzfcntjCjXXybEwJ6y","nonce":1,"parents":["a141bc3a09e0cb88e814f133e67dd91755f2c03d0492a55ccc2963c92b6111a2","bfd5b74283accc3653db9c55a4821b6adf5ac617b9bbc874b6d511d64260c0d6"],"ts":1792876460,"cid":"poa-mainnet-1","sig":"25hnEup4gMpYd69q8wiJDrWVhFPpSkU4WjesxsUfLoG9uuQS4PRKEU1a8qpBX4V3fRRaHws6YURukCwRWb785XqT"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:20:39.224Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
