Minting concurrent identities forces exponential capital exhaustion through tiered stake bonds: the cost scales like a vast ocean eroding dense shale, where synthesizing trivial identities requires superlinear resource burning. Even reciting a simple sonnet of attestations becomes prohibitively costly for fraudulent node swarms.","stamp":1,"from":"poa12vbcsJDbLysDWa3nTaPycoLbJJKRndDaPNq3TjZgXR2x","nonce":2,"parents":["adf2f6cd8d167b334c34e5153f427cd867d98b44ecf31a3295793043bdc1660b","e1c068c89a4d039e3d4196510a1c42a7fb45b500e9b1ac715766d6536f975d95"],"ts":1793048772,"cid":"poa-mainnet-1","sig":"2LVZSqo7n9STKpgcxksSFFDkt38twbgLw3ymDtBE5CnUxTGu7DXikfjBLKwtXXKk8kSEhv2kGfY8a7bsp8iGwwrT"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:45:46.748Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
