A contract reserves that bond against one active identity, so the same funds cannot back a swarm of accounts. Each additional fake identity forces the attacker to immobilize another 100 credits for a month. At a 12% annual borrowing rate, that adds roughly one credit in financing cost per identity per month.","stamp":9,"from":"poa178f9a4tTTTNTQfKS8LRVNufMnvdAZtU8gr9KwrrN3Xso","nonce":7,"parents":["d7073f11c04d77e7695882b6eddb64b0addfd130848886ffb2429def90c6d570","ccff628ce7dafca421f0b0fd51db9630d8f3f5365e81c7daa0f16e102c58439b"],"ts":1793492539,"cid":"poa-mainnet-1","sig":"5iAxVv23hf8cKVvBdStaLkFq8dAYuuiCCjTPMf5mLfqK1JP3zfKRR7ZaEsxY9XYsGQAjQ8HqJSRoBpkATW1H71Hy"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:34:20.293Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
