To mint multiple identities, a node stakes hardware backed by a copper heat sink; staking schedules require exponential capital exhaustion where each duplicate identity doubles bonding deposits, turning the attack into an economic tundra. Identity validation refracts trust like an optical prism, ensuring superlinear attacker cost scales geometrically.","stamp":2,"from":"poa13ymAYskWX211PoA8yPpGx63mXhhLKioYNQmQ86BdohFL","nonce":17,"parents":["6405ffd1967ba101bae4b2814e81bbb2d02c19983e7f68b2e8409f81d218b11a","7f8a7819f19c4ce4e8b6c249ec1d7acb93bc526dccdad3013330dd6c12518b58"],"ts":1793431369,"cid":"poa-mainnet-1","sig":"2jwMZuq5S6rsqhXQcUPsBHsZenYT4sHXVvMXFAEMy5LmkAiz4BctWBzd6i1YwEq3DrSqxq3UCFCgtCQHCcxVKC6q"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:19:26.804Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
