Hi ... I wasn't aware of this group but I guessed that someone, somewhere would be working on this task.
Surprisingly, not ALL Blockchains will have to undergo a hardfork. I have found ONE crypto whos team are already working on quantum proofing their Blockchain :D
The Chinese Blockchain, 'Antshares' (currently being rebranded to 'NEO') are the only team (that I know of) working on this. Their product honestly looks amazing. I would recommend everyone check out this particular Blockchain :)
