it gets me paid in a timely fashion, without human emotion from either party mucking things up. isn't that the goal? traditional: send PDF quote, go back and forth on quoted terms and cost 1..n times, wait for signed PO, call 1..n times reminding them to sign the PO, eventually get signed PO, do work, (at this point client is your BFF and calls you every 5 minutes asking if the work is done yet!), deliver product/ser…
I sell physical products, so an Etherium contract can't check that. Same with most non-computer services. Still, I could see this working with custom software services if you were able to write a smart contract that can test every aspect of the software to the level of detail you need. Good luck.
Agreed, I feel your pain. I would think this is only initially a solution for specific use cases, SaaS being one of them...and luckily the one I do. And in a highly regulated, safety critical sector, where testing every aspect of the software to not only the level I need, but to the level the regulators demand, is what it takes.
That said, a contract doesn't necessarily imply perfect precision. You can still deliver to vague specs and ambiguous goals and still get paid, so long as you encode something that both parties agree to. I have signed many paper and e-sign contracts that resulted in money transfer the traditional way for software that never did exactly what I expected, but eventually everyone was happy. I paid or got paid.
As to your specific use case, sure, the customer has to be electronic enabled in some way. Lots of hand waving here in the spirit of ideation... but when I was in India last, for example, even in the villages outside the urban centers, most small shop owners and vendors had mobile phones. I presume similar in all corners of the world these days, but certainly wherever HN is read. So if I am selling a physical widget, why can't my smart eth app send you a smart contract quote/invoice, you approve the details and shipping, and then fund the eth contract. Payment proceeds based on 1) physical placement of the widget in the hands of my bicycle courier who also has a smart phone and snaps a photo of the widget that gets uploaded for to the "oracle" app, fulfilling my end of the bargain, and 2) the physical delivery of the widget to your chaat stand where you send a photo of the delivered widget to the app before the courier signs off.
Would that not work, even for a physical good?
