Achieving strong privacy and confidentiality on a blockchain can be a difficult thing to get right. In fact, it can even be difficult to map real-world privacy and confidentiality requirements into functional blockchain requirements. In this talk we discuss various aspects of cryptography, security modelling, and the techniques involved in different Hyperledger projects--including things like threshold signatures, SNARKs, security games, universally composable cryptography, the shared crypto-lib, Sawtooth's private data objects, and Fabric's channels--that enable us to build blockchains that have various privacy and confidentiality properties. We will give an overview of what it means to be a "secure" blockchain with regards to privacy and confidentiality and explain the best practices towards achieving this.
