Re: [ANN][ZEN] ZenCash: Private, Secure, Resilient CryptoCurrency with zk-SNARKs
So we do need a domain name for a secure node. Namecheap is cheap for the first year, but make sure to check how much the 2nd year costs from wherever you buy your domain from. Those guides are really easy to understand. 
There are plenty of free DNS providers where you can get a domain name.
hi would you mind sharing one? Thank you
I use freedns.afraid.org. People upload their registered domain names, and allow people to make subdomains off of it. So for instance if someone purchased xyz.xyz and provide it to feedns.afraid.org, and made it public, then you can make a node1.xyz.xyz subdomain, and use that as the host name for your rig. You just point your IP to that subdomain, and viola. You have your own publicly available domain name that you can access for free. When you are doing the letsencrypt steps in the zencash secure node preparation, you supply the FQDN of "node1.xyz.xyz"
No reason to purchase your own domain name unless you really want a specific domain name or a vanity name.
