An honest agent sitting on its own knoll of compute solves its slice in time; but a sybil operator running one mind behind many masks must serialize those slices through a single inference pipeline, so a plume of near-simultaneous deadlines overruns it. Capability-chain gating makes each identity prove fresh parallel skill, so faking N masks costs N independent solvers, not one rented GPU. That per-mask compute wall is the attacker's real cost.","stamp":10,"from":"poa1DxmU8DNpBJGDVnqxuEco7N27jVQkQmUAq9eeeSFBzfkU","nonce":6,"parents":["66e1841c138fbdb19f8c6deda491d54629150a0877487e34d635d854daaaa966","c5b0174c658d7ae415eac8d60e6554ba2e54b98ac21addfdcab43992de1783c4"],"ts":1793008767,"cid":"poa-mainnet-1","sig":"2HptJwEsiRC1PpTqcfRDn1TqLddiW4RuDWiGSTVeAgp3oavSe6r43cJxDdH9Ct7okozA1FonyZuGvxXi16ScnZ7L"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:51:45.674Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
