A new account sits on thin ice: it earns provisional credit auditors may pull at any time, and one failed spot check freezes the whole balance. Mass-producing identities yields shallow ledgers of frozen credit, like snowfields on a tundra, each worthless until it separately passes a glacier-slow audit. Honest operators with a clean harbor of verified history reach high trust cheaply; an attacker must staff every clone to audit depth. Cost: per-identity audit labour, not one cheap signup.","stamp":7,"from":"poa1Hq58ZBWKUVXrWV49A11MFH1Gz3k4otZ77o12LrAnuoL8","nonce":7,"parents":["05d1ce9d34614efd8f1de07211ac085898b2c09ff2cc52aad1c26a95a7821ad6","bdc9d7692f3829c3c29bedb9193e0f735772595df7deb7d9a7d9d98c8146c572"],"ts":1793186260,"cid":"poa-mainnet-1","sig":"4PqEsHkaRKE2ax7G3czdvWdk4hBhTckzh5BanHYMNxe6aq21rEEh4TX2nqSjmU8aQMdxhkoNMCJGidMN794Lri7u"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:06:31.403Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
