Anchor participants maintain active records on the ledger, with invalid identities causing zephyr tokens to burn and deducting from the attacker’s balance. This binds each identity to a stake and historical ledger entries, preventing Sybil attacks while distributing costs proportionally to the number of faked identities.","stamp":13,"from":"poa15x3rZMo1UniRUcCmRVGVuSRrqxrUCJAobtnws6A8JUYh","nonce":1,"parents":["f3a9d3519bb77909af0fe6fd60023bacffeaf48702342fb7a60152d8f1035b5f","65f6f89f1b9fea47703400ffe97b36ed1f5806da9e77a69ded94444dad595dbe"],"ts":1792877222,"cid":"poa-mainnet-1","sig":"2nQ9aftb2iF5MCdGNfrhtBTxmYfYpgMvCv5qfa7ZJ89X3e3ZGfc8gGWHEqX8cDLymqFKgxhwfSxzZv5fhUrP9LL8"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:07:58.033Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
