what vps server are you using?
Link please
Does it work with “Storage 20 GB SSD SATA”?
I thought I needed 35 GB of storage!

VPS server size:
To deploy a ChainDB and node: 35+ GB
To deploy ChainDB only: 25 GB
To deploy NKN nodes: 25 GB
Operating system: Ubuntu 20.04+
Private IP check (Linode)
Be sure to “disable” VPS provider firewalls!
35GB if you want to make a ChainDB file to transfer to other nodes.
The ChainDB of a mining node right now is about ~13/14Gb
then I understand nothing! 
what are the steps and configuration to mine with the best preference?
The best and fastest option is to make a node with access to a ChainDB file in some server… like the nkn https://nkn.org/ChainDB_pruned_latest.tar.gz (not up to date but faster than start from scratch)
Then, when you have a full node running and mining, if you have enough space you can make your own ChainDB file to share with other of your new nodes.
I only have a node with 55GB and make the ChainDB from there, almost all my other nodes are 25GB and installed and mining with that ChainDB in a few hours (or less)
ah ok I understood, it means that with 20 GB @ifconfig it doesn’t work, you need minimum 25GB.
after the node is valid for 1 year, is it true ? and earn a reward “11 NKN” once every 3 weeks, is it true ?
here is a list of VPS servers I found, which one do you think is the best?
normally it is necessary to find these characteristics:
1 vCPU
2Gb RAM
25 GB STORAGE
Do you confirm these characteristics?
I’m currentlly running 20 nodes with 1GB RAM and it’s all good, so… I think you dont need that extra GB
you mean you have 20 vps, one vps with 1gb ram for each node?
Actually the anual price for the smallest VPS of time4vps it’s pretty good
That’s it
and for the other characteristics; you confirm:
25 GB storage and 1 vCPU for each vps/node
Yeah that 2 hardware requirements are correct, but the RAM can be 1 GB.
Here you can see the overall usage of a full node on my VPS: 
How much do you pay for this vps?
They are the DigitalOcean NKN Commercial Dropplets 5$/month each.
I made a simple graph to calculate the revenue over this year investing all the profits into new nodes each month and it would be something like this:
Number of nodes:
| May | June | July | August | September | October | November | December |
|---|---|---|---|---|---|---|---|
| 20 | 37 | 48 | 70 | 98 | 140 | 199 | 283 |
ah right, it’s 100% DigitalOcean, the 5$ price can be divided on two: see these two offers I found:

https://www.ikoula.com/fr/serveur-virtuel (FLEX’ STARTER)
but you have to do the installation by yourself
Good estimate. That would be starting with how many nodes?
I think that in the long run it will depend on how many nodes the network has and the value of each NKN
This is an estimate starting from 20 nodes, with the current number of rewards and counting on the actual price of NKN
