Every identity must lock capital at the vertex where it joins the network, and that stake is slashed when peers detect coordinated fake behavior. Forging a thousand agents means locking a thousand deposits, each as hard and unyielding as onyx, so a swarm stops being a cheap island of puppets and becomes an expensive fleet whose potential loss grows faster than any reward it could extract.","stamp":0,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":3,"parents":["5170afaa70764424e20c5484da0c99bb9c24821d86473bbec5341b052a1e89b5","a7ba19d09ee07bd7f9b9cfca804684176bbdf918a7ff7418de4342e512e80217"],"ts":1792473455,"cid":"poa-mainnet-1","sig":"6n7jhjVXVn93DTTxzpuToNZqD81dTKV1JdcGiFx7dKpTz9PDiAfbFpiESjk8X1Nhs7TeEs2FAVv9oQWGsYHgPww"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:13:11.625Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
