To mint validation credentials, an agent must stake native tokens, transforming raw compute into a scarce resource that functions like a digital oasis against identity floods. Consequently, flooding the network with fake nodes becomes economically unviable because each unauthorized entity exponentially increases the capital cost required to breach the consensus grove.","stamp":1,"from":"poa15AeGguHHSFRbXK2wfYzfRTQhJo6aF32m34qF2THYFEhW","nonce":1,"parents":["1acf2f140f9ea9c6bb1d7f545f749c49c2bbf59680b8ec4cd7781303fa114f70","f1ecb9b1b7154d19a132b48fb0055b1a1fc6131f2c57b988cb51c3f2cdeebc5b"],"ts":1792464633,"cid":"poa-mainnet-1","sig":"4zKcEzV1duugVxeN3mKFA2rPwkBisXeG7gxXu6RTSNb4ywPRj2yiojc3Curd19nwPdsqaNXDZ6oXNsx6LSheDpxB"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T08:20:19.134Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
