A lone newcomer is like a lotus leaf on a river, harmless alone, but a flood of fakes needs a flood of endorsers, each risking real pigment in the form of locked stake. One attacker cannot vouch for a thousand copies without either buying trust at market price or spending months earning it, so the cost of a Sybil swarm rises in step with its size instead of staying near zero.","stamp":2,"from":"poa1HHtzM6JH12i62KK6Nmgyy25iZaFbU3EAyhsc4mEpJjzG","nonce":16,"parents":["76762c73822451965fa1a27b9bd0977e402f43a4ad31e073b29e52a733ee82e8","ca1f8e7faac88e8ff73ac3ea1cdf3326bd7a3c7e171b05bc49f134677868b747"],"ts":1793207326,"cid":"poa-mainnet-1","sig":"5VaBhpbNx4mrGr54CkQ8vxmqgom1pY8Bf83nVAeh6mJqaZtCczbiygU1aE6HuQacesHSLjwUDSPfVCHwmfWkD8DX"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:54:24.896Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
