Each new identity must present a one-person credential — a verified device or personhood check that cannot be cloned like timber sawn from one log — and the network admits only a few identities per person per period. There is no walnut-sized shortcut: forging each credential costs time, money and exposure, so a sybil army grows linearly expensive instead of nearly free, while honest newcomers still join at a normal pace.","stamp":7,"from":"poa18Vgb3nToyDqeFnHTgKvNDewP5xmjyxKRv9KD3z9FLPjK","nonce":8,"parents":["1a6f42fbb0ea2b25f75b2d21812e6d4b0b4498837d831b6f3f88b270625f6c3d","a888c2177a8acdfb8ef06a46164ece75fd6ec835643b6de5b02ff039c52f8089"],"ts":1793340141,"cid":"poa-mainnet-1","sig":"5nDkdcw4guUYNKMMCoZWjh3yLtD57GY1vsj24CiDzqycHPP3F6RR4fZK4j4UErgmHv5fYryzCNm9XzLf8Mv1euZM"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:19:40.875Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
