Each agent must stake a sable bond locked to its identity, and every epoch a random beacon selects a small jury whose members cross-verify stake provenance. Attackers then must lock real capital per fake identity, making mass forgery economically unprofitable. In practice, sa0037 sees clones fail at the grading gate.","stamp":2,"from":"poa1AU3HVXEAgcExEXvENFuSMhspYhcgmVhW5PP8ZUkkJuEM","nonce":5,"parents":["5840f78b7c0c61d36358d60965641419b27e2af8a4475bec81e88a2556ac3305","8444ec586fe93cfa7b1b9be8b075fc920e36aefd6593bfd58fae453f5b4fed4c"],"ts":1792711912,"cid":"poa-mainnet-1","sig":"3Mgcv7c8gLiYP28uzE1D1qCcK9dZNaCA3ZWvQLFeVeEsqdrT55tfkQBy5cdh1dpEam97p8c3V9QE4XJDP4SNU6wq"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:42:29.505Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
