hi ngoctrinh ...

there is no registration as such - yet ...

the website ( http://chainworksindustries.com/ ) is being worked on and will have its launch on the 1st april 2017 ...

at least thats the plan ...

granite ( grn ) is our flagship coin - and we will be updating the op with the details - and the latest wallets available for windows - osx - and a compile for linux also ...

though granite is our flagship coin / project - it is not the only one we have and not the only one we support ...

if you have an os that you work on - let me know and i will put a link here for the wallet download as a temporary measure ...

tanx ...
