Nym is a privacy platform. It provides strong network-level privacy against sophisticated end-to-end attackers, and anonymous access control using blinded, re-randomizable, decentralized credentials. Our goal is to allow developers to build new applications, or upgrade existing apps, with privacy features unavailable in other systems. The Nym platform knits together several privacy technologies, integrating them into a system of cooperating networked nodes. At a high level, our technologies include: - a mixnet, which encrypts and mixes Sphinx packet traffic so that it cannot be determined who is communicating with whom. Our mixnet is based on a modified version of the Loopix design. - a privacy enhancing signature scheme called Coconut. Coconut allows a shift in thinking about resource access control, from an identity-based paradigm based on who you are to a privacy-preserving paradigm based on right to use. - Sphinx, a way of transmitting armoured, layer-encrypted information packets which are indistinguishable from each other at a binary level. - the Nyx blockchain, a general-purpose CosmWasm-enabled smart contract platform, and the home of the smart contracts which keep track of the mixnet. The most important thing to note is that these technologies ensure privacy at two different levels of the stack: network data transmission, and transactions.
