The elliptic curve pairings that will be added to Metropolis will enable fully anonymous transactions as in Zcash. The zk-SNARKS that Zcash uses for currency transactions can be used for a wider variety of transactions in Ethereum. The elliptic curve tech will also enable things like the BLS signatures used by Dfinity.
- ianmiers 9y agoAs a practical note, on that curve, Zcash is about the limit in terms of complexity for what you can do practically with a SNARK. This is why ZCash is switching to a much faster construction and supporting curve which gives it a lot of room for interesting features. As Vitalik mentioned on twitter, however, that is a long way away for Ethereum. Most applications of the pairing curve operations are probably going to be signatures and the like, not SNARKs for this reason.
