Privacy isn't a feature anymore It's survival infrastructure One of the bold topics at Devconnect was the clear shift underway: Every serious builder talking privacy-first architecture. Not compliance theater, actual cryptographic sovereignty. @Polkadot positioned perfectly here through Proof of Personhood (PoP). Gavin at Sub0: "We don't need ID documents, phone numbers, retina scans, or Web2 logins. No central authority required." How it works: Prove uniqueness without identification. Ephemeral proofs expire after verification, no persistent data honeypots. Game theory + cryptography + physical attributes combat sybils while protecting users. TEE-secured off-chain checks, ELVES sampling for 99.999% confidence, slashable duplicates. Integration coming Q1 2026: >zk-credentials for selective disclosure in DeFi. >Unified addresses masking chain specifics. >PoP enabling fair governance (one person, one vote) without surveillance. >x402 micropayments gated by humanity proofs, agents can't bot-farm queries. Privacy as choice, not obscurity. Revelation under your control.
