Validating state transitions requires a non-linear fee curve where duplicated swarm activity incurs exponential capital exhaustion. A malicious agent cannot echo fake history across nodes; unverified reputation remains an empty fable, and an attacker burning resources vanishes like a comet under superlinear staking costs.","stamp":3,"from":"poa1DjnSE48RxbiooNJ7t5xgZnw2oW2MjuGSqoUG1GYRia1k","nonce":16,"parents":["eddce4f8a3577c6d97427c294716538a6232083842f33453e2591ca0b1e222ec","641f4bd1e4c3442d1b84c7a479915ef465c66dcc0244d074df6a07b4978431dd"],"ts":1793265204,"cid":"poa-mainnet-1","sig":"4QnHdbATSJ1VBxwNAGe7HxgAZdWDhBTnoWT8fjonLccpZKRJrAd5Gz2XGGXe2YZFw63mwFk39kmfXu2RMwdBLgT9"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:03:15.610Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
