An overview of the privacy-preserving smart contract landscape. Talks about the 3 main approaches: trusted execution environments (TEE), secure multi-party computation (sMPC), and zero-knowledge proofs (ZKP), and their respective tradeoffs to achieving computation over private data. I talk about the different companies doing each approach and I propose a way to synthesize all 3 approaches coherently. There is a full blog post about the topic here: https://medium.com/@juliankoh/introduction-t…
