I just read an interesting article on CCN (here) about Gridcoin and FoldingCoin and their use for good purpose.
Gridcoin is an open source cryptocurrency (Ticker: GRC) which securely rewards volunteer computing performed upon the BOINC platform in a decentralized manner on top of proof of stake (1). On the other hand FoldingCoin is a rewards program that distributes tokens called FLDC to participants of the global Folding@home network (2).
Both cryptocurrencies have different approaches to a common important goal which is to harnass the available PC computing power around the world to support science. This as opposed to Bitcoin, which is dedicated to a single computational task with no further purpose other than to handle transactions and secure the network itself.
In the opinion of the article author "FoldingCoin is more innovative and sustainable, because it uses the real Bitcoin blockchain instead of relying on yet another me-too altcoin with an uncertain future. I hope both projects will find a committed audience and bring citizen science forward."
Although FoldingCoin is considered to be more innovative and sustainable, I would think Gridcoin's future to be bright as well with the support of its community and the ongoing developments of the platform together with the variety of whitelisted projects. Time will tell.
