Various forms of cryptocurrency

The bitcoin which can be said to be the original cryptocurrency was started in 2009.
Despite not having been 10 years since the concept of cryptocurrency has been completed, the cryptocurrency has made substantial progress.
In the process several new cryptocurrencies appeared following the bitcoin.
Here, we will introduce some major currencies and characteristic currencies among them.

Ethereum

Ethereum (Enterprise) is the cryptocurrency started operation in 2014.
It is the most famous alto coin (a cryptocurrency not a bitcoin), with the market capitalization being the second highest cryptocurrency after the bitcoin.
The characteristic of Ethereum is that it allows you to record not only the information on sending and receiving money but also the contents of the contract as an outgoing gram in the transaction.
This makes it easier to exchange e-books, music data, etc. on the Internet. This mechanism is called a Smart Contract.

Peercoin

Peercoin is the cryptocurrency started operation in 2012.
Peercoin is not so famous as compared with Bitcoin or Ethereum, but it incorporates a system called Proof of Stake.
The Proof of work system adopted by bitcoin has a disadvantage that you need to use a lot of energy for operation because it requires computation by a large amount of computers in order to preserve value.
Proof of Stake says, "As we have more cryptocurrencies, we do not want the value of the currency to go down because we do not want to lower the value of the cryptocurrency, so we will not do the wrong thing by themselves.".
It is a system that makes it easier for people with a large number of cryptocurrencies to hold blockchains.
This technology is considered to be an excellent system rather than Proof of work as energy consumption for maintaining the blockchain is reduced and as users increase, it is drawing attention.
Peercoin currently operates cryptocurrency using a system that combines Proof of work and Proof of Stake

Monacoin

Monacoin is a Japanese cryptocurrency started operation in 2013.
The cryptocurrency made with motif "Mona" which is a character made with anonymous bulletin board is used for donation, change of money, construction of shrine, and unique use by user.
