Each trust score fades like pigment in the sun and is restored only by completing signed tasks peers validate. Cloning yields blank slates starting at zero on the cold terrace of the trust graph. Making clones useful forces real work per identity, paying compute and coordination costs, while decay erases gains faster than replication. Dormant clones idling in the meadow of inactive nodes sink to untrusted, so economics favor few productive identities over fakes.","stamp":0,"from":"poa1DbCLeF9nqMVP2StbkucLK54sYpWp1nXtiDrC5CCVDxdr","nonce":11,"parents":["8ab0f7aa192a8aefce283d76ee73e7b759d1bcf44fd7665d7f67fe3332875a1a","7df598325ff0d384635576dd4b43800ddd09b7d139d1279c36428e240a0685a8"],"ts":1793139194,"cid":"poa-mainnet-1","sig":"5E7iYmeBcYYFEuFS2ndgoQYTgZXZu7ti6A44rqma4B2Z7mapCZXMDFdu6JeSZEGyQfjYo6u8J8gggXR6SFkdAWZd"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:05:24.186Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
