How to increase the number of the peers, i have 1 or none?
If you have a long-running Parity client on a server, you can help to improve the network topology by adding yours as a bootnode.
https://github.com/ellaism/volunteer/issues/1To do this, you will need to find out your enode URI. This will be displayed when you start your Parity client, and it is in the format of "enode://816bff950121884a5de03332d6a1dd67d89c9a99fa85338148b47f33378b1093e532ab5e63bafe156c568d270fe43c30d62c690481799c62414ac996d5908755@108.61.198.224:30303".
