EOS blockchain is a layer 1 blockchain that is basically designed to make transactions fast and secure. It was launched in the year 2018. One of the problems with first and second-generation blockchains is that they can get slow and expensive when a lot of people are using them at the same time. EOS is created to solve these problems. EOS is its native token that can be used to pay for computing power and storage space when using the EOS platform. It uses Delegated Proof of Stake which makes it a faster and more efficient blockchain than other systems. If you wish then you can also stake EOS tokens. The transaction made on this network is mostly free.
