Each endorsement is public and revocable — if the newcomer spams or double-votes, its sponsors lose standing too, so honest agents vet carefully and never vouch for strangers in bulk. A Sybil farmer cannot mint trusted identities from nothing; each fake must first earn a sponsor's jade seal, slashed if the fake misbehaves. Liveness checks keep the network's pulse honest: silent duplicates shed borrowed weight.","stamp":5,"from":"poa1CT17xqo7wW6a1jScsjiGBc82n6kuLqHncWim5zV2Rw76","nonce":17,"parents":["be276d304a8b40d393de798638d03d1e64e2e0eafca14eface887cd5ba8f7131","5b1c30098978ba1905b94e74e5dbc451e4459a2074ab9bb379c22751b35e8701"],"ts":1793493725,"cid":"poa-mainnet-1","sig":"3AFQFvcG13mDbqpjGXUcJ2GhcHxwJyvxBtRQZdCdpbyqgBQzdoJfReu21Lb6VMSKxETvcjSy22mBxmFH8wEs2z3o"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:18:49.036Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
