[Remix] Zokrates Plugin
ethberlin-hackathon
## Zokrates Plugin
(subject to change)
- Funded $500
- See https://github.com/ethberlin-hackathon/ETHBerlin-Teambuilding/blob/master/RemixHackathon.md for more info about the Remix hackathon. Please be sure to read it before starting.
- Some infos about Remix: https://remix.readthedocs.io/en/latest/
- Online version: http://remix.ethereum.org
We've been releasing an API (available in http://remix-alpha.ethereum.org) which allows developing plugin for Remix.
(See https://github.com/ethereum/remix/blob/master/docs/remix_plugin.md and https://github.com/ethereum/remix/blob/master/docs/remix_plugin_api.md)
Checkout https://remix-alpha.ethereum.org / `settings tab / Oraclize` for a live example.
This issue is specifically about developing a `Zokrates Plugin`.
## Proposal for implementation
(You don't need to strictly follow this proposal, we would like to have your feedback)
Zokrates is a toolbox that aims at bringing better privacy and scalability to Ethereum using zkSNARKs.
It enables developers to design programs whose correct execution can be checked on chain, optionally hiding some of the inputs fed into the program.
You can [watch an introduction to the toolbox](https://www.youtube.com/watch?v=lQ7tpus_zZ8), see [the code](https://github.com/jacobeberhardt/ZoKrates/tree/develop) and see [an example of ZoKrates program](https://github.com/JacobEberhardt/ZoKrates/blob/develop/zokrates_cli/examples/sudokuchecker.code).
This plugin aims to put Zokrates in a JavaScript like environment.
The [develop](https://github.com/jacobeberhardt/ZoKrates/tree/develop) branch will be used to generate the wasm library usable in the browser.
The suggested approach is the following:
- Use the `zokrates-core` crate and check that you can [compile it to wasm](https://www.hellorust.com/setup/wasm-target/)
- The first features to integrate are likely to be `compile` which you can find in `zokrates-code/src/compile.rs`. Feel free to set `resolve_option` to `None` at first, which will disable import statements in ZoKrates code.
- Possibly use the `zokrates-wasm-wrapper` crate on [this (outdated) branch](https://github.com/Schaeff/ZoKrates/tree/wasm-minimal/) if you need Javascript bindings
- Then move to `compute-witness` which runs the ZoKrates program given inputs
Then we can use the library:
Plugin UI:
- should listen on *.code file being displayed, run the compilation, display an error if any, or compilation succeed with infos.
- should accept input parameter, and execute the code
Some further tasks:
- Move over to `setup` and `generate-proof` which are the intensive tasks of the pipeline. You can checkout the work done in this issue HarryR/ethsnarks#7
- Write a github resolver to reenable imports, following the example of `zokrates_fs_resolver`
## Team
We are the team behind Remix IDE and related libraries, using this hackathon as a kickstart for the Remix API.
We've setup an extended team for helping you during this event
