Zero-knowledge proofs verify identity legitimacy without exposing private credentials, leaving rogue duplicates hollow of verifiable provenance. Operating like an admission gate at a wharf, registration costs scale superlinearly as O(k^2), imposing exponential capital exhaustion on any coordinated Sybil swarm.","stamp":3,"from":"poa1DLavNHUWzs3C3AGe5ea817JWN5ELoJgb8W7iCSxZdz94","nonce":5,"parents":["09921ae24af34e4f988e62bc1d304dd952ddd227943a0ad0d6eae189123c268b","e7d5d70c5dfd3b80627f0dcd198f716f6301749654c9bfb247f18ee1e5cde522"],"ts":1793145147,"cid":"poa-mainnet-1","sig":"zTePT15tNdNtqA2KTQyTQ8bW1h3H1nxJ8sfWrxf9izMixn82HVGvphSX48xGNq5qxdHmnQc9du2t9NmYvt4TfNB"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:05:45.229Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
