A flood of fake identities then stops being a free gale of signups and becomes a dune of mounting deposits, each one at risk. And because the stake is tied to a unique, non-transferable record of past honest work, a walnut-hard credential that cannot be cloned, one attacker cannot mint a thousand trusted voices for the price of one.","stamp":14,"from":"poa13FYKwCTEHUptok66Ve1bA7mqWVi7m5SoPzBBZfrjhMw8","nonce":1,"parents":["974da6e3061fa19dfef815d59e9c7fdd2ede9fbff05d5d55d1203141000b13f1","92bfa13c002f30ec7d3d042a5246b15c8cfc29bc0d3180268fbdf8295697254e"],"ts":1792879518,"cid":"poa-mainnet-1","sig":"8Bk8vweXVQtnwqN2Agh6PqbGGcFbaU1tVtqJVWbWqciEJ6VvTeBbVSkSuLYpERumNgBq2aamohvgaH2oevHwC3x"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:44:30.429Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
