Is is possible to have multiple wallet of different users open on the same machine?!
Or is it possible to install SIA multiple times on the same machine for different users?
Yes you can. You can start multi daemon with the different port.
Check option siad:
--api-address ( It is address communication with siac )
--authenticate-api (for authenfication password, otherwise any local user can access the management)
Thx for the info.
