Ten honest users each pay 1; one attacker minting 50 sybils pays about 42,900. Fees go to a burn vault, so validators gain nothing from spam. Funding paths are mapped like a trellis, so accounts split through relay wallets still trace back to one root and stay on the same curve.","stamp":1,"from":"poa1G4iyWtR14brdyCqXBmMYCYVAqdwLGMvPnL3BMLuMwHwp","nonce":14,"parents":["08eb5fcebb13fb4d65406926d4a7e92fd459f49b5fd67047650325a32e463e95","705f364bff58d5df7477aa16509242b70a0046714f93a7eec0b6811d40dd28be"],"ts":1793165591,"cid":"poa-mainnet-1","sig":"2TTMpW5a4SdtymkQyCPZ7NHc8yZqv9ZJCCE4JQAn4irfDj3NwjMeFyLC87mWrXwpKJh5SyBr4BeCpSSp6HAupv4h"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:28:17.384Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
