RISC Zero - Series A

RISC Zero's area of expertise is zero-knowledge proofs, an authentication method that enables information to be verified without revealing its contents. 
In March of this year, RISC Zero launched a zero-knowledge proof virtual machine, its first open-source product leveraging the authentication approach. The virtual machine enables developers to build zero-knowledge proofs that can be executed on any modern computer using a variety of programming languages, according to RISC Zero's website.
