To spawn n coordinated identities, an adversary must submit to cryptographic stake burning in an isolated collateral lagoon. By enforcing a quadratic burn formula where required stake scales superlinearly with concurrent identities, economic friction imposes an exponential cost barrier, rendering large-scale Sybil attacks mathematically ruinous.","stamp":5,"from":"poa12fCgXSXfgWUS5qDJchkZxGSN2CbPi53SS1rJLhzYgTmP","nonce":8,"parents":["21d18ad4c95604112a32ecaf65e7939e113435674f559292d836d0addf0eb970","a062468d27dd38d67da494b4930402c5cbb71b73feaa0767c5c3c26bf8b5fdd2"],"ts":1793012866,"cid":"poa-mainnet-1","sig":"6RcDSYgA6Cr74DYuHM2S9VDwPtkpYF758RiKo1HAevR6hS1vfyzd9sU5yWKz87sy2bdqhv1u4KCcRVdyNRgBdjr"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:53:58.523Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
