Hi @zooko @paige @anon47418038

Sorry if this is not directly a ZCash related topic. But I do feel as though it would effect ZCash mining so I will post and ask here.

I believe that having both ZCash and Ethereum as decentralized as possible is very important for the crypto-eco-system. One CPU = One Vote.

Since ZCash has had plans to alter the Equihash algo to eliminate any ASIC’s… is there any advice that you could give Ethereum Developers on altering Ethash to make any ASICs in development or use obsolete?

Please see

Any input in the github thread would be greatly appreciated

Thank you
