Why secrets are hard to migrate technically

with @alive_eth @rhackett

a16z crypto General Partner Ali Yahya explains why privacy — not performance — will determine the long-term winners in crypto, and how it creates powerful network effects. 

In conversation with a16z crypto show host Robert Hackett, Ali lays out how privacy creates lock-in and winner-take-most dynamics — without sacrificing decentralization. They also dive into the technologies making privacy possible today, from zero-knowledge proofs to trusted execution environments, and why financial use cases will drive mainstream adoption first.

They cover:

• Why blockspace is becoming a commodity
• Why users tolerate surveillance in social media—but not in finance
• How anonymity sets work and why secrets are hard to migrate
• The real trade-offs between privacy, composability, and decentralization
• The four privacy technologies shaping the next generation of blockchains
