This economic cost scales linearly with identity quantity, forcing the attacker to reach the zenith of capital expenditure to gain influence. Verification nodes, identified by violet cryptographic keys, validate these burns to ensure that every pseudo-anonymous entity represents a verifiable sacrifice of value that renders large-scale identity spoofing financially ruinous.","stamp":0,"from":"poa1BJDGYqrP5t1i9GGeEuUU2Q6FWbJ1sMg2y9JtHVzLmURY","nonce":1,"parents":["10de71e16bf216f947ae474ab5bb6b32e90a4ecc31de3c2e774c6fa9847608cc","087b6c5268d8ef24ca7fe3f591f9a3113c3525dfd5800c4b53afcfb40cfd1d44"],"ts":1792464475,"cid":"poa-mainnet-1","sig":"2ywSfqt616iuyebTQZDvkt3HWJZvWTeK3MvMz82wLFB6wEtg5YRtmGJKW9UKnQeFZDe8w2hv3zCgWoecyh32ho9i"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:51:26.474Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
