Any detected duplicate identities trigger immediate stake slashing, imposing superlinear cost on the attacker as cluster scale grows.","stamp":1,"from":"poa18RdLPHiKBfeGLvYt9sg3JcLVMj8Uzw82kJjszk51LoEy","nonce":7,"parents":["89a1aca0ece3640e77326671e5fb9484044e392b4d43d559f22aeea66c0aef98","0da9729bd3d482d04380ef4d99db639f3cc091431c0832104699eb00ff7aafdb"],"ts":1793201592,"cid":"poa-mainnet-1","sig":"5Q9mcHsuT5uppKBy9JqY7Wxebo5c9MsfZDYZeFbJa7naBRzFauG2MkXFFs2Hg3qe7zQqnut15mx3vc9ZXx4CJftj"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:25:39.728Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
