What happens if it turns out that you can't deliver the product? Will the funds be lost?

How transparent will the whole process be about the usage of funds?
 
As you know you are enjoying a level of anonymity that would never ever be possible in another economic environment, especially if it comes down to raising a good amount of money. When I read a sentence like "I can't guarantee it will be delivered in a certain time frame or for a certain cost" I know that there is a risk for a request for follow-up financing, may it be justified or not. Would you be willing to agree to a % threshold relative to the initial amount raised that you definitely will not exceed and still deliver the product if technically possible? Otherwise investors have pretty much no choice if asked for another nice amount of money or they will suffer a total loss whereas you have been compensated for your work.

Thanks for your responses so far!

Of course there is a chance that funds will be exhausted and the project will not be finished. If that occurs, investors will have to decide whether to provide additional funding or drop the project. I don't think either of those outcomes are likely, however. My design document is very complete and no one has even raised a concern or flaw in the design (yet) that wasn't already considered and addressed. Soon someone will, but we will just adapt the design. I understand you would like me to guarantee it will be delivered on time and on budget, but that just isn't possible. Anyone who makes such a promise for a project of this kind is dishonest.

Developing a reliable decentralized exchange is a groundbreaking technical feat. So there is risk. However, I regard Nu as a comparable groundbreaking technical accomplishment which was completed 50% under budget in USD terms and delivered in a reasonable amount of time. I am the ideal architect to deliver this novel solution and the Nu development team is best qualified to implement it given our past accomplishments.

We are happy to release figures on what has been spent by department:

1. Core development and marketing
2. NuBot development

We are also happy to regularly report remaining funds (I have already been doing this quite regularly).

I'm sure you can understand that our individual contributors would be uncomfortable with us publicly releasing details about their rates and individual payments, as is the case with any organization.
