(Ethereum) is the premier blockchain network that enables the definition of smart contracts and hosts thousands of decentralized applications. Ether with the symbol ETH is the native coin of this network and the second-best cryptocurrency in the market after Bitcoin. If Bitcoin wants to be a decentralized payment system, Ethereum wants to decentralize everything.

A brief history of Ethereum and Its Technology

In 2012, at the age of 17, Vitalik Buterin was introduced to Bitcoin by his father and became very interested in its technology. Vitalik started writing for Bitcoin Magazine and made suggestions for creating Bitcoin platforms. When these developments failed, he decided to create his own digital currency. The version of Ethereum on the Internet is one in which a network of systems called nodes replaces servers and clouds. Nodes store and maintain a common database called a blockchain. The more nodes, the more secure the network and its data. The information stored in the blockchain is confirmed by "consensus". This means that more than half of the nodes must agree on the correctness of the information before it enters the blockchain. Hacking this type of system is almost impossible, as you must control more than half of the network to force login. Even if you control more than half of the network, it will cost you so much to complete that it won't be worth it.

Features of the Ethereum blockchain

The Ethereum blockchain uses the same technology as Bitcoin, but is more advanced and can be much more useful than the Bitcoin blockchain. Some of the features that the Bitcoin blockchain lacks are as follows:

1. Smart contracts
2. Decentralized programs
3. ERC20 tokens
4. NFT tokens: A non-equivalent token or NFT is a unit of data stored in the digital ledger known as the blockchain, which does not consider the digital asset to be unique or interchangeable. NFT can be used to create things like photos, videos, audio, and other types of digital files.
