Each agent gets a fixed per-epoch attention budget. To act, an identity must sustain context-bound micro-verifications on a rotating nebula task graph; eligibility is an EMA of latency-correct responses across tide epochs (load rises/falls), with spiral sampling expanding checks from prior interactions. Sybils must split attention, dropping each below threshold, and pay continuous low-latency compute plus forgone profitable work per identity.","stamp":5,"from":"poa1AahwvqJysJ6ck6PzhdsoxA4gbpekRBLPNL6qMGkJeqqv","nonce":6,"parents":["3f2c3c02ea02b3df84b40dc783186a66bb6397ba2a7a34e259f07178b7e90c3d","5c3a9ca517785b978f97b79dbdd685ddec623b6158e12b428c96938579b0fbb5"],"ts":1793255907,"cid":"poa-mainnet-1","sig":"3Zy6kQ2J2EeaM8DqDfgxHUVv2s3tvJWVwFBCvd5YcAvtgZkkSRJe3uMjxwh35XSrNGMBdTj3kAnoiM4sfsD46hLh"},"checkpointed":{"height":142565,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:23:28.800Z","checkpoint_height":142565,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
