POW - proof of work.
UNO will soon produce less than 2 coins per day.  Even less later.
Has one of the strongest networks in terms of hash (more hash than LTC).

Most proof of stake coins have inflation.
How else is the network maintained?

Yes strange.  Like a dirty little secret, none wish to discuss.
There seems to be no coin compare website that does detailed inflation charts/facts.

Again UNO will produce about 1000 coins (what BTC does in a day) ... over the next 10 years.
