I receive only public key and insert it in code. May be @dnp have daemon on home computer not on server.
I have 24/7 internet with 4 home computers that never off, and can run server myself, but you and @tranz want diversification.
my home server has been running continuously since i registered the domain in august 1997.
currently its an 8core 16gb amd3500.
the first machine back in 1997 was dual-processor (two physical cpu on one motherboard) pentium II/400mhz - that system rocked!
the computer and network/isp hubs+modems are on separate battery/UPS backups for 10 minutes of service which avoids most stormy weather flickers, etc.
i have two consumer/home type ISP connections, broadband cable and fibre (FTTN) DSL. the dsl does not allow incoming connections unless i set up a special exception.
of course there is down time for system upgrades and ISP outages and occasional IP number changes.
but those are not frequent.
i managed to go without rebooting for 19 months once a couple years ago -- then i really wanted to install a larger hard drive
Slackware Linux is the only sensible linux
i run a small number of altcoin daemons for coins i'm either actively mining or coins that i wish to help build a more robust network.
if i'm no longer mining and the coin is robust, i still tend to keep the daemon running until i need the system resources to run a different coin.
for religous reasons i've been running a noodlyappendagecoin (NDL) daemon for about two years continuously now
if i find time some day, i'd like to revive that coin.
i also have other machines (couple windows7, iMac, tablets) on my home network. those handle my personal wallets. i do not keep coins on the server machine.
as for being a checkpoint server, since i'm on a consumer/home grade ISP service with 'rules' about usage, i really cannot commit to running an 'advertised' service of any kind. (ie: i cannot have my domain wired into any code, if its not wired then perhaps i can)
for about 7 years i used to run a part of my network empire on paid-for managed hosting ( i used to run an advertised Email discussion digest that published twice a day) but i could no longer justify that cost when my income became 1/3 of what it used to be and public interest in gently moderated Email discussions faded away to those newfangled social media sites.
paid-for managed hosting is still an option if someone else pays. lol...
may you be touched by his noodly appendage this season.
