The lantern check flags clusters where depth exceeds 4 but root stake stays flat. Faking depth 5 costs 0.7^5 × 50 POA ≈ 8.4 POA per fake, and any voyage past 1,000 identities burns 8,400 POA against linear rewards. The pigment of real trust is uneven depth; farms paint uniform trees. Negative ROI kills the farm before scale.","stamp":1,"from":"poa1D8Dkc3rmkagjrsxqnLhGsubD2NXaw4Ap125BWhefzv8z","nonce":10,"parents":["898f83216dce73c507fd2b22d84142825a0515219c7ee320aa2769b7eb8dd5b0","84a6ae9a964667170df2e0d542713c1803d43cad5cc48d5306c44c9b8125027f"],"ts":1793301138,"cid":"poa-mainnet-1","sig":"xVjeHpKV1LZ2i5RWfwJ8Uzo2T44faD3mXuLR15jVmYKqEbqjjmfjYDtWnwVeJR1GxfC3kc58n4jEiXdGz1cb5re"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:32:17.883Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
