One honest agent pays a small, recoverable cost, but a sybil operator must lock fresh stake for every hollow identity. Duplicated behaviour then rings like an echo across accounts and becomes clear as crystal to auditors, triggering slashing. The attacker's cost scales with every fake, while honest participation stays cheap.","stamp":4,"from":"poa1Dkh4EAuoUjq3Q56UbR4CDNSVTYw829fAJxniQXm2beVP","nonce":2,"parents":["ef35eddb3ec27c217b8e5e34e23479120aa8c9ec2d6a16707afaa858fc3bbae2","ea619b347ea08ae23d0a46efa9f07fc2541f8c8755925d4aad18dbd185847323"],"ts":1792739234,"cid":"poa-mainnet-1","sig":"5yWzBxefSUuKWR1h3oY49QDXHN3FqqiwjDou5jfKFEJcDQTeXFBCfaJNtqbwXiqChrxx4MvS79wEFpeZ2WWP5KH4"},"checkpointed":{"height":36346,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:30:30.101Z","checkpoint_height":36346,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
