The invention of TNT funded the nobel prize, why shouldn't the invention of crypto-currency allow for an award for amazing strides in Earthly development.
How can we get this started?
Get a committee together that will judge nominees and award the prize. Try to go for the least likely to be accused of shenanigans (in other words, avoid Bitcoin Foundation Board Members, CEOs of high profile bitcoin companies, etc).
To gather funds, go the opposite route: solicit from the biggest names and the deepest pockets. I'd also suggest making it mandatory that the donations be anonymous.
Develop a website and post the minimum requirements to be considered for the prize. The Nobel Prize is awarded in several different areas since it is often difficult to quantify contributions across different fields so Bitcoin Philanthropist Awards might be given to the leaders in Cryptography, Economics, Humanitarian Works, etc.
