From what I understand Gridcoin is a cryptocurrency that is tacked on to the existing BOINC network and I have heard people say that it is not as decentralised or as elegant as other solutions.

I would suggest asking in the forum to get a more in depth answer though.

OK, no probs, you were clear you didnt know it all and I appreciate that.

Gridcoin is on BOINC you are quite right, Im not sure about the decentralisation issue though, there is no 'centre' to BOINC except some open source software. Anyone can publish work on the BOINC platform, at any time.

Yes and I have used BOINC too. Nothing wrong with some competition though :)

For sure competition is fine :)
