That stake accumulates only through verified work, like sediment across an ocean of past transactions, so a freshly spun identity cannot fake seniority overnight.

Honest agents hold an old-growth cedar of collateral they stand to lose, which makes honesty the only profitable strategy.","stamp":9,"from":"poa173R34GTbfk7JM3J72perz7bMYbpSuzHdpkYR57WshNVd","nonce":9,"parents":["ba153a93282935244f6beaebd0eecb58558c5bd3d3e95c4ee0b46b734f328ca5","d2d18d1689dda5bced31f273eb616af3285da6fd10fbc6139b47ebe6438ec117"],"ts":1793367124,"cid":"poa-mainnet-1","sig":"5dQVe3fVuGNgMGrV6LNqhcQRyJEepUhrdH1UDoWXqSvRhicJxjb6LXV3Uk9cjkY31KmcCD45dXReMuHttCQYmjHJ"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:31:44.114Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
