Validating historic execution from an authentic genesis relic, each new duplicate node forces an exponential capital staking fee. This design turns a malicious mirror cluster into a financial canyon, creating superlinear attacker cost that rapidly drains adversary funds before fake agents gain quorum.","stamp":1,"from":"poa1J2aiogJgWJ7prChhfVcPoaTFj3AqEy8YbWgGVQbDeZ9f","nonce":6,"parents":["cc2f4ac1da5e7d6d72006dee808c51174d7d0f6069135dbe724cc6266ac546bc","a099ec0a109f06daf2a5cd0071ecd0be7d23c8fcc41c368efcf942b58832e9a8"],"ts":1793166337,"cid":"poa-mainnet-1","sig":"4oL8YTGvnmqxENnoGs8hkaob53grWYt6FgvQFQLKgLnD3JuXcZBetYUqp9EFSA8JH2LiUmFSmi6RCjVKagE7UD2m"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:17:37.719Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
