CLOSING KEYNOTE - Security is What We Make of It - Blockchain and Beyond
summary
Argues blockchain is fundamentally an information‑security product and distinguishes public chains (world‑readable, pseudonymous) from permissioned ledgers used by banks; cites JP Morgan’s open‑sourced Quorum with confidential transactions, Zcash’s zk‑SNARKs and the Powers‑of‑Tau ceremony, and warns Intel SGX is not a privacy panacea. Notes Bitcoin/Ethereum throughput (roughly 7–dozens tx/sec) versus Visa (tens of thousands), ~12,000 Bitcoin nodes, and Coinbase opening 300,000 accounts/day at peak, concluding systems exist but interoperability, governance and usable privacy remain unsolved.
