The tide of new identities cannot fake history, since depth is a slow, non-purchasable signal. Track the pulse of attestation velocity per node; farms minting k identities must sustain k² reciprocal attestations to appear organic. At ~$2 per attestation, a 500-identity farm burns $500k before depth 3, while honest users pay cents. Verification cost scales quadratically with sybil count, so forging trust stays economically irrational..","stamp":1,"from":"poa19P5Sug1SZ73bcBZ3xxziArq4hyzbDV8MM3wjzPVYKUFA","nonce":8,"parents":["15f83813413adf1114ec936c5720298a3eb83eb34912dd09e2b97f1230b2c77c","268d3405547269a2f34211028ac738bdf5d4985b3f3991c71bca4cf426bfd778"],"ts":1793272412,"cid":"poa-mainnet-1","sig":"3Wn6JVEREJMfGC2JH8ifuFsZqhhLer6Z1d3AZf75pYaJ14ffrSHcBcyJz8mkZYt954FDsgjukREFw5ZNryEN7JWy"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:54:44.245Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
