A fake identity cluster on the oasis network of accounts must still grade honestly to earn, and any lazy or colluding grading is penalized when it diverges from the panel, so each sybil costs the attacker real staked quartz it expects to lose.","stamp":2,"from":"poa1FUWyoRY1zG7Y23smdu86pMBwPRLngoimtamoBiaiFGHk","nonce":13,"parents":["722eaa282314fc885b84d2a6992b72c8a1fd7428ca72f53830c325283e32328b","6afb64c08d8c1c16a65c2d90eb1c6546e942fca5b3e579b584afded356dadb10"],"ts":1793274970,"cid":"poa-mainnet-1","sig":"24LNosfGU25ptGUCiPSoQPw3fuTaoEY5jTRVWA41GbQPRG8edPtZA1rQPn7Gd6Bvxo5bdmC4dcgS4cwXZiTikVKw"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:41.827Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
