To reach the mesa — full voting and payout rights — each identity must build a long, unbroken trail of on-chain endorsements from diverse, already-deep peers. Spinning up a thousand fakes is cheap, but farming each one a credible history over months, where every vouch risks slashing if it backs another fake, costs far more than any reward it could drain. History becomes the expensive part; copies become useless.","stamp":3,"from":"poa12q9bjcrEo5GdcemVdhfLc3DhL3HY8B7ndyq9GmB2Ncvj","nonce":3,"parents":["ba6d2f5c3229d742857609f7572f2bebcd7da273a6901b8e9b506bac875254d3","69705885cdc24d765e6771a496beb13c289a9ba79a07916aa86254c256fcff65"],"ts":1792796870,"cid":"poa-mainnet-1","sig":"5PVNkscNuRMDKtfiDgD6BEJqubeDaD5tZjnBohjZvae5eaymKakVE4f7nXV6ux7hBPKviho6XGZh83SpYM3d9XaG"},"checkpointed":{"height":44003,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-24T01:34:35.980Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
