An identity with no plume, or a plume copied from another beacon, falls into an umber quarantine tier where its votes carry no weight until it rebuilds genuine tenure. A sybil farmer must therefore run a live beacon and earn separate witness support for every fake identity, so cloning adds no free influence.","stamp":0,"from":"poa148jXn4RWiAg5P7p1spHsJnTTZESPEsqtj42gnZSxkzGx","nonce":5,"parents":["77fca96279e252d04fb605b7f7f99b7566e27eb2173172f9840b4a5b8fe08027","088c1c13b05e2c1691f722d2392594a410c8286192221c570e59d5ffb54d79d9"],"ts":1792955482,"cid":"poa-mainnet-1","sig":"2sxb4NkXsWaBfVN7VqwiWsswqzQZrperhztz4LupQafYM9LZPu2CGRH1mghKxyt3qfRXjJ9HZeuqZS9ij778ixd8"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:50:36.908Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
