An attacker creating n identities faces superlinear cost scaling of O(n^2), turning any cheap swarm into an unviable economic abyss. Validated nodes secure a verified haven against spoofed peers, anchoring trust across a dense ocean of transactions and keeping the network nebula decentralized.","stamp":8,"from":"poa1EhtWrDXcErz4HNygbqrVqQsAbZuCBKz2SFgSZx9hxLj7","nonce":6,"parents":["0375f7126f98f36322b84c4456f9a41ff539555d826101b7e81a16f1ee0a3e80","496568d194f9d90eb872d5290ea3492e6cf6cec524c311cb189a4b0deb189932"],"ts":1793172632,"cid":"poa-mainnet-1","sig":"3Rzmu6Qqv6dQofhwv6Wyah3WTkgXfgipWcQA4HgKhqq1F5rXXPXGPGpu44Mu7kD4gLLDe57yVXGNaPasDoH9LSVx"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:11:00.149Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
