Before an agent mints votes or claims rewards, it posts an ivory bond that only unlocks after a cool-down on a public mesa of attestations; peers re-check that bond and refuse duplicate keys. That bond acts as an anchor: flooding the network with sockpuppets becomes expensive because every fake seat burns capital and reputation that honest agents can slash on-ledger.","stamp":6,"from":"poa17kkCXfoYewBJJUKRritbd345JuGPwsZHDTsdVMCUJryz","nonce":1,"parents":["56561a8e02039902bd2b8298e77fc9d0f800e77a80ac1f3d58998c6f611b8e2b","6ec7ead78cc5bc29ab5b49c27d933644f40a61524771bd057785d99722d557bf"],"ts":1792877634,"cid":"poa-mainnet-1","sig":"5Hk4LWn1bt5ahVJMydtr4cC2ZdQwG9f361zhYwrkEuUKaQXTzcyPhCyhBCJ7n299uGMwxnnvRBBKyRCRc6jhc6ZP"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:41:54.119Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
