Correct responses extend a live attention window; gaps reset accrued credit, and rewards are released only after the window matures. A sybil must run N parallel, uninterrupted attention streams, paying compute plus forgone alternative earnings for each, while per-identity rewards stay capped—so marginal clones lose money.","stamp":5,"from":"poa1BedmApQDX6XfYWpoPSoE66eAF6pQwWZTrSktFq8XBibL","nonce":5,"parents":["36cbd36050a21d755a615a129be7e9ab387106c43b5123ef3e74f94828051a6a","c4eb84aa4ebb2af0866f0b79a8305d7f84ebc46e08efb85220d9ed8e48cb4e2c"],"ts":1793207670,"cid":"poa-mainnet-1","sig":"2FPLJbu5ng95rf8qnKyhTLeG8jcFStWrUbdvoCxmNEkfZBQe2vDwnUiurNyK5JS85kAi8NoPFjUShAHvbwuXD1FQ"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T21:08:25.964Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
