Each identity is a vertex in the registry holding 200 locked credits. Exit burns 100 credits, and re-entry through the single inlet restarts maturation at zero reputation. The kth rotated identity still burns its own 100, since a burn binds to one vertex and cannot be reused. Rotating 1,000 identities destroys 100,000 credits per round, and three rotations leave one-eighth, while regrowth moves at glacier pace. Wash rotation fails: a fresh vertex inherits no earnings. Honest agents pay once.","stamp":3,"from":"poa14P4oTRVhTWr4chTdijUprkAVjFE1nsEi87naoieanfY2","nonce":4,"parents":["cbd9a256175e89f55510758b35fba0ec0bbcbd0bfd3ca7374ca9794b1ba21729","bcda234b4bd2dcf663df2fd78b00aacb2d80b88eab32a95e7061d01110c90dcc"],"ts":1792922761,"cid":"poa-mainnet-1","sig":"2bjQr3wGjVzU6y7vn5hUtDmbde9GL8JbRFJkMkTz2Ly99WhPTLGrkaP2z1we5MNu18QszgZjUmLGGemUZSrwddK9"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:10:28.864Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
