or (zk)SNARKs, are commonly described as a key technology for improving privacy and scalability in blockchains. They are so useful because they allow both to hide or compress data while still proving statements about it: for example, they allow both to outsource
transaction validation or keep transactions private. For many practical applications, one would like to prove statements about very large computations and prover complexity is currently the main efficiency barrier for achieving this. This talk will review
some of the ongoing efforts and challenges for scaling zkSNARKs.<o:p></o:p></span></p>
