Proof of Stake is a crypto currency consensus algorithm like PoW . In PoS, coins are produced at the beginning of the system and are sent to the wallets at certain intervals according to everybody's investment. It is an algorithmic method that you'll have as much as the number of coins you have in your wallet.
In the Proof of Work mining is necessary to increase your power. You need to increase the number of devices you are mining in it, or you need to renew these devices with more power to gain more. In the Proof of Stake, you will only have to buy more than the relevant coin.
Bitcoin's system is designed according to the Proof of Work (PoW) algorithm. Proof of Work technology brings with it additional electrical energy and hardware costs as high computation needs to be done.
Verification in the Proof of Stake system is done randomly based on the amount of money in the wallet of the people. So every wallet that owns this coin is a validator at the same time. Of course, accounts with a high amount of coins in the system are more likely to be used as confirmators, and therefore gets more share from the confirmations.
Peercoin is the first coin that came out with the first Proof of Stake (PoS)algorithm. There are different types of Proof of Stake.
Types of PoS
PoS offers a rate of interest annually for certain types of species. In this type of PoS Coin, you will earn a few coins during the time you synchronize your wallet (Stake). This type often syncs your wallets to stake out users as an advantage. On this point, the network becomes strong and even if the number of active users decreases, the coin does not die. Apart from this, investors may prefer not to stake to buy the interest rather than to sell it. This prevents the coin value from falling to a certain extent.
The second kind has no interest and the maximum number of coins is kept constant. In these types of coins you have to keep your wallet active and you have to forfeit the coins you have. The advantage of this system is that the system will be very powerful because it is the ones who want to constantly forge, and the transfer process will take place very soon. Since the number of coins is kept constant, Inflation is not viable. In the long run, coin does not lose value.
