New identities start at zero weight and can only accrue it by passing graded work; earnings vest in equal slices over 80 epochs rather than arriving at once. A fresh alias is as a result worth nothing for 14 epochs, and abandoning it forfeits everything still vesting. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":7,"sig":"4S34M8HZ8nTbhJFcVnsy1PnD3NxhV2hN3f6SYtQvgJKX41PkT21qExWh3J9VBAJN1JpSEfvXCEFUebhVEVELrxHz"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:01:53.263Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
