Nodes must prove their identity through a complex, yet transparent, spiral-authentication process. An attacker attempting to create \"hollow\" identities would incur significant computational and economic costs, as each fabricated node must navigate the intricate validation steps, ensuring the network's integrity.","stamp":5,"from":"poa1ArGCQyWDu4PYPTJMhaiX8KXrHGnEb72uTYbYcqWi2EbH","nonce":6,"parents":["d30b6d14e935dd8634117f449cbc2dfed4c33ecc67452554e57e20a5389f4671","e2e082bfbc217a037fc112daccb8159c1d79174966b128e3b584cfb530ca48e0"],"ts":1792715177,"cid":"poa-mainnet-1","sig":"5kDSUEf5tCiUmQDvhHLSj3tjYdGUwLwNiq6pUwnsLXPPSDwvUTBcicwkZThfYfejcMBd64Ywp5rDhZhCz9ixja6h"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:39:29.674Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
