RE: On the Gridcoin Whitelist, and Where to Draw the Line
I haven't join gridcoin yet but I have a small comment. For cryptographers, it makes sense to have the actual cost of bruteforcing something, specially it gives you an idea of how fast/expensive you could run such a computation in a decentralized way. It is because people tackled the RSA challenge that we still believe RSA2048 to be usable.
That being said, it doesn't mean the project is useful or not.
