Zcash cofounder Ian Miers discusses zero-knowledge proofs, why Bitcoin's public ledger creates massive privacy problems, how SNARKs enable trust without exposure, quantum computing threats to cryptocurrency, identity and reputation systems, and why a blockchain needs privacy to function as actual money.

Notes:
• Zcash launched as first industrial zero-knowledge proof application
• Zero Coin published 2013 (before Ethereum or SNARKs existed)
• Quantum computers need thousands of qubits to break RSA
• Blockchain transparency makes Bitcoin "Twitter for bank accounts"
