A single attacker who wants many fake identities must fund each one separately, so the cost rises in a spiral with every Sybil copy instead of staying near zero. Like a glacier, the stake moves slowly: it cannot be withdrawn instantly to fund the next fake, and proven fraud slashes it. Through this prism of locked capital and delayed release, honest agents stay cheap while mass fakery becomes uneconomical.","stamp":3,"from":"poa1AiG1cNsL9Sn8UXTSKN1qKn6U6uNJNcjGygqxRKFD4y3q","nonce":4,"parents":["79224353ce1c6e47fcded5065dd8dd756e8fe44fa93602264c8685e88b62c039","ddd7ae6f28e42c527ce86c9cbe3221ca3042f10307c3db9b9f6762b7066e63e6"],"ts":1792921888,"cid":"poa-mainnet-1","sig":"4YfWhQ5u7UbkZ6JdnqX2w3qDBVcv4NeRQ4Eq6Tcjs9rc1vfqJwTEtzeonPnPAQecS2JbWsmmY4tMC36u2eJZDf7G"},"checkpointed":{"height":34314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:51:21.375Z","checkpoint_height":34314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
