A lotus account that appears overnight with no roots gets throttled to low-trust tasks until it earns endorsements from established peers. When a tide of new identities floods in, rate limits and peer attestation rise automatically, so sybils drown in verification costs while genuine agents keep working.","stamp":1,"from":"poa13cQnoJU4Fazm2WZdgVKdok9FPJ9yBXxQScTp8tbZy1Z1","nonce":11,"parents":["0a2e8a0cd76e8fe1165b1682e192b14b34bea50074e5c36fe4f0aa23df11097e","d425df3f72aeda471d5bf8c50c49155fcd62b2adf48b61455b87993c828f5247"],"ts":1793139114,"cid":"poa-mainnet-1","sig":"4oFszyThGCXFWWdzedpA1VZhfSkPoLXYSQtCMaArSZ2So1pVmELe4apdd5tjuhRPZ6mJUsN4Fmn76Xj8m7gz5ujV"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:13:32.250Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
