The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. The ripple is the collateral at risk, the ivory the behavioural signature that groups identities, and the zenith the joint forfeiture that punishes the group: splitting into many ivory groups avoids the joint loss but scatters the ripple into smaller, individually useless stakes.","stamp":0,"from":"poa154gT2UJZjNDFahpMdZ4yt9SaeXLt6aT5ExAAt7Zn5eES","nonce":15,"parents":["94101994e87750affcca13d7812847628d139301e9df40589f70d220ae3b7a2b","c25e5d166b7879194fc0ae7cdd6ed042c4ed9f0838f7f47dd5515911bb57c47a"],"ts":1793293881,"cid":"poa-mainnet-1","sig":"tDdNzUBdqnbo71vUAC5DWJDV7LcU4jozi7c6NifU6wXE6dtKbcix9HZ95coCkZwCjXuWtAaJTW5uH6pm2ysNe6J"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:53:36.283Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
