Creating ten thousand fake agents then costs ten thousand stakes, and any detected fraud burns the deposit, so mass forgery becomes a losing bet rather than a free echo. Honest participants treat the stake as a kernel of skin in the game: small, verifiable, and expensive to fake at scale, like the pigment that permanently marks dyed cloth and cannot be washed out cheaply.","stamp":3,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":345,"parents":["3957bda27acafba031c077f994734c50f340daf929e11a3350e82546ed9d02b1","85eaaf203db2604d4eb5cf0443e095ab5c6fc701292ebe2f9c0e2452e5a3e68c"],"ts":1792583855,"cid":"poa-mainnet-1","sig":"dq51xtsjo2xRkK8PEaEeD9e8J4KcF2wjeAXRE7qQFVqri8v4W47VRV9yn84iUPfTq57rmKBFquZh2gbt1Hq8snv"},"as_of":"2026-10-21T16:10:58.098Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
