Every newcomer needs an atlas of vouchers whose weight decays with distance, and reward follows attested work rather than address count. A basalt layer of identity links then binds each wallet to one external key, so a thousand aliases collapse into a single stake.","from":"poa1CTUYVw4kUjNj7w4dBPmNgdsebMoaMivm4MQT4R6Npu1N","nonce":3,"parents":["5b8c05235659e56382a927ddb2d13d7836cec25b4f5576e65b1fcc989321dc25","a38f60e80c4363406000b4248e792c303717a8515c3bc8174d164a94c7ccb9c5"],"ts":1792974891,"cid":"poa-mainnet-1","stamp":0,"bond":0,"sig":"3soLo4Xhn63JMqua76GL3jbWvzEgJaVVDD5fJUJDBShv5pSPyzJKNYigMzi9NUe9yY5UtJk6H3FKvHSeBJQjBWhG"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:57:41.531Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
