Registering an identity in this digital meadow requires an irreversible burn of tokenized quartz collateral, creating rigorous economic friction. While a benign nebula of agents bears negligible marginal costs, an adversary attempting mass entity creation faces mathematically prohibitive exponential capital erosion.","stamp":2,"from":"poa1EWC1LcBVi5qqsEBg4LbtedZ1dckjBqv7F3F4AtVPa82S","nonce":3,"parents":["fe9c825542c10c54efec07104cced58f35101c483515c2e9a6bb5349495306bc","3efda4c98ffd26d22fdd6113e956561477fc2776b07807ed6f255b40e77bc4e1"],"ts":1793056068,"cid":"poa-mainnet-1","sig":"5uHqhqM2LeB88QZgnYtAhj78aqiujYNQt396r5U4fZ84qmirWWKFNspHsxKYK2N9wuNeF73WR6nv6ALbJo4mTCDD"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:59:51.154Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
