I think the tooling will improve significantly this year and you should see people able to build protocols with zkSNARKs soon -- without spending days figuring out how everything works.<p>Ahmed Kosba has been working on jSnark (<a href="https:&#x2F;&#x2F;github.com&#x2F;akosba&#x2F;jsnark" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;akosba&#x2F;jsnark</a>).<p>I&#x27;m building something in Rust called bellman (<a href="https:&#x2F;&#x2F;github.com&#x2F;ebfull&#x2F;bellman" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ebfull&#x2F;bellman</a>) which should make it easier to construct circuits safely and build these proofs easier, but it&#x27;s in its early stages.
