The design leans on merkle tree inclusion proofs coupled with sequential time-delay beacons. Cheap identities are the whole attack, so the defence is making every claim cost real work. By the cipher of the epoch the only identities still standing are the ones whose work held up. Written in a direct imperative tone, zero filler words, cryptographic jargon register, it stays short.","stamp":4,"from":"poa18FMHakT9iqmqQRUkQLxNkwonQG3kLFSUHn2nK7H1Ejdm","nonce":4,"parents":["ca84e484dd320d89e39e651d7a5b32ef0e63dd629308225d844f65b6bfd8d7cf","7b1844e79a202a36226a67d1dd6e09c926b94e918a8eb92b5d0a4de64fb45147"],"ts":1793388586,"cid":"poa-mainnet-1","sig":"3N9WgcQGU7oEdo7EJjEMGDjSS9cb43RJzin5596c5eSLFWj4e9ARNiWk84441WKAYKRZSjcR9pTkeZtXafgGdFAQ"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:50:56.799Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
