Each identity must keep a large random dataset and answer surprise challenges about it; a hollow identity sharing one disk with others fails because the answers must arrive faster than data can be fetched.

An attacker pays the full disk and bandwidth cost for every fake, with nothing earned until much later.","stamp":5,"from":"poa1BdCQcC3rZa9aA22cXDvgqk9m2z2KyXaWoroMxExDakmq","nonce":3,"parents":["1e409adc9b00f3647ffe7eade38cb37898e722b50b91a9fbcdc61ccfc078f219","07bbadcb2fcd95f7b4b5cc67f4c66398911559928f85ec2422723f2b9cdef93e"],"ts":1792965812,"cid":"poa-mainnet-1","sig":"gVJqkpU8uSde4yTUBKHoeryjQq8YCDdE2FrTeD2U1ci9xAo6z4SJQwyGdwNNTG9kjBw6ZbUQkLQkxq8CDjMNowD"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:44:29.272Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
