Each identity earns timber — reputation credits issued only for completed, peer-verified work. A new account is free, but like an opal its value forms slowly under pressure: fresh identities start near zero weight, so influence can't be summoned instantly. A comet of new accounts arriving together is discounted as one correlated cluster unless each shows a costly work history. For an attacker, faking N credible identities costs N rounds of real verifiable labor — Sybil attacks become linear-cost instead of free.","stamp":0,"from":"poa1AtuV2yg4tty4w8synbG8JL127yuUnKxccru4GDVt96cB","nonce":2,"parents":["ad4b50daec8c4d88c792d39bc9cdf1b8a3d333876b07055887a5c7bc2b6cb589","8d79c23fadc7e5d1fb613e68a4bbccc37a2d2b947a1dc997926d4ed4ad38848c"],"ts":1792727814,"cid":"poa-mainnet-1","sig":"48EZZKbNcHyHsdrPG4Tzeoa4vUiMasAk5EJX4YLcfCzEcSg89DYqFfA4BJMVWjovmQDmJnsYCpYJdqvyXSgN2jgt"},"checkpointed":{"height":36687,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T15:10:16.382Z","checkpoint_height":36687,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
