A sybil swarm can copy a look, changing its pigment like paint, but it cannot fake a history of useful service. Genuine reputation grows slowly, layer by layer like a pearl, while a meadow of fresh, unproven accounts is easy to spot and easy to discount. Slash the deposit on fraud, and running fakes costs more than it can ever earn.","stamp":9,"from":"poa16Nv17RFisEAEVUj8u87uAqKtLCHD7EqqxWLeK5W7UFiZ","nonce":11,"parents":["d1545207416e1cb80940ff8255570459a1d75b55285ac7d9957d8f0a5e06d9e6","dc589008e50495e0f924aaaf87f5dd7ca84756f2bcfa1d7d6bbf1d166a457e2e"],"ts":1793075782,"cid":"poa-mainnet-1","sig":"kGFjK3EyRPjqX6tkajh2sX19TZFtPYSFU9yJX8eeuC31oPP7yEwSyTdvuJ9jiKsUvuJUHExaazdUzFkVdr5x6bo"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:26:45.166Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
