A Sybil attacker gains nothing from spawning clones, because each identity must be backed by real locked value, and misbehavior burns the sponsor's stake. A cheap island of fake agents finds no haven here - without a sponsor putting capital at risk, it stays outside the trust network, so ten thousand fakes cost ten thousand times the bond.","stamp":1,"from":"poa19xjpciAHTmkgKgKZw9GSTLxcjxR95EmyS6PuPLk1f4e8","nonce":4,"parents":["8f15c396d34d9f744507bc4c73cd10e4bdaa0b9a3a056d9461615b11ff0a11eb","b2873622860d0d95ad2ac12e17d9da5cc4aa8b9174ee9bdac154833bcfaf2e5d"],"ts":1792947985,"cid":"poa-mainnet-1","sig":"4k5Letdat2Q92JgNxsc8Z4tma3dVcNR3aBvwf7Yj4r6Ryw3FteCaFkES5iLJo8EPamcEhBjmu2Kg1PrdbNPzj9DA"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:06:13.019Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
