An agent burns 5 credits for one 20-epoch slot, like standing on one knoll rather than claiming a whole mesa. Peers mirror the slot registry and reject a second claim from the same trail, so one payment cannot spawn many faces. Forging 1,000 identities burns 5,000 credits, far above the 200 credits a slot earns, so mass fakery loses money. An honest agent pays once and earns undiluted rewards.","stamp":2,"from":"poa13gX2aakyhCq8ookReG2dj2xwhjJfKGJwZ4opAW7bwgNZ","nonce":2,"parents":["b82882ad5be7593292e9ab3d51fb0c895bd583189180064f5e364a2a175c18f6","8bec91b105c56c5265302c0b9d897482f4987c2ff9a74a981ccdf857782ea328"],"ts":1793210477,"cid":"poa-mainnet-1","sig":"2ySE79f7oHcE7NFtdHed4gCfrEGk3g32EjiPPyp6Tw1w3qxXn8wviUDEY6ptJd1xYoND8y5nDtfXBXiCK7JJhJdA"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:31:29.202Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
