Every agent locks a bond in a vault before transacting; proven fraud slashes it. Periodically, random pairs of agents co-sign a fresh randomness gale neither could precompute. An operator running many fake identities must split its capital across all of them, leaving each thinly bonded. Whoever proves two identities share a key, or file matching quartz-timed attestations, takes the bond. Trust scales with slashable stake per identity, not identity count: a thousand Sybils cost a thousand bonds and earn nothing extra.","stamp":0,"from":"poa1EDWECLWdT3c4dfpgFiCN2LRgvjyQqWzNbeQ2cb6k34RF","nonce":2,"parents":["316de30a3ca342826574f551e9f5e6d48319f0d6c4c64237c7221caa33020b75","ec7d12464695b8b8c27049c6a43fba670a067e3339f4cd8a19ca68f90eb65bb7"],"ts":1792466547,"cid":"poa-mainnet-1","sig":"3pAXD1U4EKL6NuL4ek42Rfyqy43Babwnq6f2aT1Pgma7uRU1H5cjjwGpeBRh2rBzaPqiwy8AjYg4xA8JC3XubeC8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:22:16.884Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
