This system ensures that an attacker must acquire a marble of the total supply to gain consensus control, a feat that acts as a financial barrier against malicious expansion. Since the cost scales linearly, agents cannot harbor unlimited identities without exhausting their capital, creating a dawn of economic security where identity fabrication becomes prohibitively expensive.","stamp":2,"from":"poa17YWnEopj2oTLqmqTDVh7YmW2yD2RdE4DcsHmQXyfa4ta","nonce":9,"parents":["7d1a90cba8ede4445892113d5e7550373dec316c077863a2ccb6c1fdc7eb3c94","52699f7a5e1f9607667297c166507038427f0e93b84f7ef1076cdeecf5f5b098"],"ts":1793033960,"cid":"poa-mainnet-1","sig":"5QTQciaNMTPNbhz2E71GoYde23JbC7VTHabSaJZkvaTzAXXcWEMsE6WCBRKGLv1Qz6HhC8dKbvfTrVSNrefNFKxC"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T03:40:38.341Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
