Since setGoalFailed is public (because you want it to be callable by the person trying to achieve the goal, and the contract owner is the supervisor) and does no checks, seems like anyone can mark a goal as failed and the money held in the smart contract will go to the contract owner? Shouldn't that check that msg.sender is either goals[_hash].owner or owner ?

You are right, thank you for spotting this! I will have to make a new contract, this one is flawed. If someone decides to call this function and I get the funds, I will give a manual refund. It will have to do until v2 release of the contract. Right now at least it's not holding any major funds.

It is kind of awkward that a business that exists to help you get things done is paid whenever you fail.

Doctors and pharmaceutical companies are supposed to help you be healthy, but make more if you're ill long-term. Banks, credit card companies, and brokerages all make more money if you make poor financial decisions (fees, interest, and active trading, respectively). Auto mechanics and car companies make money if your car doesn't work or doesn't last past the warranty period. Even piano teachers only make money if you…

Which results in unnecessary procedures, and unnecessary prescriptions.

Which caused the housing crisis and great recession.

>Auto mechanics and car companies make money if your car doesn't work or doesn't last past the warranty period.

Which results in some of the most untrustworthy salespeople in one of the most untrustworthy industries.

All of those industries are regulated by the government, precisely because the incentives are wrong and it causes people to do more harm than good if left unregulated.

I don't really understand the trend of solving all problems with "smart contracts". This just seems to limit the potential market to people who care about smart contracts, and complicate an otherwise simple arrangement, without providing any benefits. You still have to find a supervisor your trust, why not just give money to a friend instead?

This app reminds me of the cartoons where a character says 'lock me in here and don't let me out no matter what say'

Yes, it's inspired by "Go Fucking Do It" and Pieter, the creator of the original concept, is aware of this re-implementation :)

It is kind of awkward that a business that exists to help you get things done is paid whenever you fail.

But in this instance, that's the incentive. You want that money back, rather than going to someone else.

They didn't implement the most difficult part of the idea: the supervisor. Seems like a half-baked solution. Interesting, but incomplete.

It asks for a supervisor's email. I'm not aware of how these smart contracts work. What else needs to be done?

The incentive structure you are describing is a huge part of the problem in the statist/industrial paradigm of human existence.

Blockchains and smart contracts purport to lift of out of these conditions, but, as you point out, this one seems to suffer from the same flaws.

I was able to find a trustworthy mechanic. If they did a poor job or were sabotaging my car when I brought it to them, I would choose another mechanic.
