Each node stakes capital in an orchard of trust bonds, where minting cloned identities incurs exponential capital exhaustion scaling as O(2^n). Even if an attacker strikes fast like a comet, creating swarms triggers superlinear penalties that instantly drain malicious reserves.","stamp":1,"from":"poa16UZGse82tVLvhh4fua7LV3afsGvQpMBYHZ872g9bG6wr","nonce":9,"parents":["3141929f4bbba9da813e6f0c02a3b2de39dd9c5ab9285751d438e6fae7e926e8","6b826ba085e90105cdbb52141875f5f901e5fc687b9eacb719017675e8344591"],"ts":1793035407,"cid":"poa-mainnet-1","sig":"2mrEUQQFKmGAGGc2TiV4sdWzTYTw6z9r4LdKt7yv2KJknq2os4f9sSis4fwymhEMpD3JYHnb6CoPTndWq6Ax2USN"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:22:08.026Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
