As Ethereum, banks, and others seek privacy measures in the wake of the increasing amount of data breaches of our sensitive information, zk-SNARKs and zk-STARKs will both be put to the test. Whether it’s either of these or something new, may the best proof win – it’s vitally needed.
zk-SNARKs stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge Proofs. If your in crypto space, you might have heard about "zk-SNARKs" . Details are either sketchy or explained in a very complex way. Even the white paper from Ethereum has complex explanation to be easily understandable. So it takes some time to wrap around this concept.
The creator of Ethereum has written a blog post that contrasts zk-SNARKs and zk-STARKs. In it, he begins to explore the features that may make zk-STARKs an attractive solution to various problems facing the blockchain platform, as well as potential future problems.

What are zk-SNARKs? Zcash is the first widespread application of zk-SNARKs, a novel form of zero-knowledge cryptography. The strong privacy guarantee of Zcash is derived from the fact that shielded transactions in Zcash can be fully encrypted on the blockchain, yet still be verified as valid under the network’s consensus rules by using zk-SNARK proofs.
The need for fully anonymous transactions, of course, is clear, but I've been wondering if it would be possible to flip that upside down--would it...
zk-SNARKs in this scenario optimize a way of using the blockchain as a verifier of general computational integrity off-chain, with verification times on-chain magnitudes faster than execution times, in the logarithm (that is, the inverse of exponentiation) of the steps or cycles involved (measured in gas expenditure on the Ethereum blockchain).
