All of these cryptocurrencies run on POW (proof of work) algo, the first POW/ POS (Proof of stake) hybrid was introduced as Peercoin.

How Cryptocurrency works?

Cryptocurrency are entirely digital assets which don’t have any physical forms like cash. Like in bank your cryptocurrency/bitcoin address is tied with number of currency you have which is recorded in a decentralized database. Unlike bank’s database, this databases are distributed among all nodes (computer/servers that run cryptocurrency wallet) that will save a copy of that ledger/database so that even if one nodes/copy of ledger goes offline/deleted you will not loss any of your balance. But if your bank’s server goes offline you will not have access to your money, this is one of the interesting feature cryptocurrency have which makes a lot of sense.

But how does cryptocurrencies are generated? There are two types of cryptocurrencies namely POW (proof of work) and POS (proof of stakes). In POW miners will get free crypto as reward, amount can be different among different currencies. Mining also requires specific mining hardwares but in early days of launch when mining difficulty is not that high simple personal computer or laptop can also mine POW based coins.

On other hand, in POS the one who will just save their coins in their wallets will get extra coins based on annual interest set by developers/community.
