Self Commitment App

It takes 30 days to build habit

You commit to do 30 workouts in 30 days.

Create a new challenge

Good things

• End to end
• Verified on Etherscan
• Uses the Arbitration and Evidence standards

Development

Realistically speaking - it's a hackathon project, unlikely to be continued.

I already have some other ideas how to use Kleros. "Oracle as a Service" - human intelligence API to tell the factual state, knowing that rational game-theory incentives are in play on the Kleros side.

1. No surprises here

• git clone
• npm install
• npm run ganache && npm run test

2. Check open issues

Actually if I was to report everything, there would be too many.

3. Local version of Truffle (required to run the tests)

Kleros reference implementation is using pragma solidity ^0.4.15; it means there are some deprecated solidity features.

If you have Truffle installed globally and run truffle test IT WILL NOT WORK - the command will use gloablly installed Truffle that in turn has a different version of Solidity compiler.

If you want to run tests (hint: you want to run tests) you should do npm run test - in that way it will use locally installed Truffle in node_modules. It will compile, it will run.

4. Debugging unit tests

1. Put debugger statement in the JavaScript code

2. node --inspect-brk ./node_modules/truffle/build/cli.bundled.js test test/test_to_debug.js

3. Open chrome://inspect

5. Preserve credentials in MetaMask for interactions in the UI

Have the same mnemonic each time, to preserve account in MetaMask:

• ganache-cli -m "____ ____ ____ ____"

6. Increase gasLimit to 8000000

Especially if you are using Remix.

Consulting gigs and impactful work

Effective altruism. Exponential technologies.

I live in one of the most expensive cities on this planet and I'm open to extra work.
