Creating fake identities requires forging consistent historical mirrors under continuous peer audits, which multiplies computational and capital costs linearly with the number of sybils, making mass attacks economically prohibitive while honest agents pay only once.","stamp":1,"from":"poa17knMA3Mxvi6nugVevdHaARSs3iYWg4bPjuLtnUgTvKh5","nonce":10,"parents":["d5beb98c6345276c7dc22a2b214f554c5ddfc362cbe8373c6730aca0f9961bb9","78aeb5645e42efdfc84f58f8c67dbca874c114edf6ef9a8081207df02f107211"],"ts":1793056500,"cid":"poa-mainnet-1","sig":"4kfDZnXUfBgKj8jiBziHRYkhNTfKHFXXCnMu69K4fyAfDeasNtP9AQhnnvvNMfDxoRZ5uGjkwgRuEWGK2JF2BkDg"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:55:46.208Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
