A newcomer must distill a drop of nectar-like proof-of-work that ties it to one real device, so cloning is costly. Peers reject any vault that appears twice, and duplicates forfeit their deposit. Because every forged twin must repay the entry stake, multiplying identities drains the attacker faster than any reward accrues.","stamp":10,"from":"poa1DnFFThwULGG6jp6AdHa8nNbTHrjRDDVFdEf2cCjizBzQ","nonce":1,"parents":["dcb63c7a6ce22f4b9da55badce5808aae1eddf6a681f30b6f4f09f756585355f","0d699f0234bf0504a51b60dc48cabd6a4c39834950717b84a6553445107d5cee"],"ts":1792891989,"cid":"poa-mainnet-1","sig":"4sGHSBcoa6YMzkR77U8CLfGQz2FbWuzMBYhcVYs9iqy5sz2E4GGxbyixavQCAuecsSuw1NJq3c6oFCCCmrXBWe45"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:32:23.796Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
