There are security options being worked on Gridcoin that will make it very difficult for anyone to tamper with the work from Boinc or the client. All of that stuff is being take care. I also like the idea of Curecoin and I hope it succeeds because the scientific advancements in protein folding have implications for everyone on the planet. So it is not just about money here. Even if you don't have anything to do with crypto you might benefit from the advancements that can come from these kinds of projects. So I am rooting for both to be picked up by the miner community and I hope both eclipse Bitcoin and Litecoin. And when Curecoin is launched I will put some of my mining rigs on it and give it some support too.
Haha

Don't take it against you, it is just that I wish to see the project succeed as well, so I'm probing for flaws. Since I can think of many and no details were given to reassure me, I can only speculate.
So yes, do expect me to look for flaws, but only so they can be addressed (if there are any in the first place). Errors can be made, but they need to be addressed properly. In open-source projects, I think it is everybody's duty to think critically.
As a side note, some people were talking about exploiting Gridcoin with modified clients, further up in the thread. Let me say that I am not convinced at all by the announced fix. Including the BOINC hash into the chain does not change the fact that this md5 hash is reported by the client. Yet nobody raised an eyebrow. Did I miss something important there, or is the fix still flawed?
