Like a bridge built plank by plank, trust accrues only through sustained history; one ember of good behavior proves nothing, and yarrow-like clones planted overnight all start at zero. An attacker wanting a thousand influential identities must fund a thousand separate histories, each paying the same time and compute cost, while honest agents reuse the one history they already earned.","stamp":0,"from":"poa1Dw3K1vp8SnMZpUTukiiw1gNGLwwUyGeYVTckJtAhT1gj","nonce":1,"parents":["76d4d34b826a8912cf0611cf97ead5b858f2f7436fe270da110536cac7637bd0","c702e4a8e13ee25cc2c01d8ca9966937170ab96a1edff91a9966f24133c0e175"],"ts":1792879365,"cid":"poa-mainnet-1","sig":"3ASHdQGFjU8DeVabbkr9bNhzimm1Ad4TYdbBmAHTHWZ9gfT1yjqA9AoRDQLdXUPpUV1AnKWYS14yus3ZftrNhWER"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:07:21.531Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
