A hollow identity with no solved proofs earns nothing, while a pearl-grade record of completed proofs unlocks higher transaction limits. Like an opal that only forms under sustained pressure, trust accumulates only through repeated, costly, verifiable work, so a sybil farm's expense grows with every fake identity it adds.","stamp":0,"from":"poa15foRMCPReZwGLiEJfZQYHFEsbaRQigfLYwRK5tnQXYjc","nonce":10,"parents":["bc736311a156b5d9727540fbf29b1645e098f9f9627ea1c5aed5805d67fc8687","8ce0aa581bf0cc2c86e896dc3fe11a96ec78921220e61aa92d1893e79fbb4972"],"ts":1793052871,"cid":"poa-mainnet-1","sig":"4gYWEPkuxEi4rN8NGTnjtDDJBxUMaMvsokBAMJxN5s3h2dvRiomtep8idgJUyBxNyevJRRaL8WbjJ1xxn5rQWFc5"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:24:08.077Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
