what is ethereum?

Ethereum is a decentralized blockchain with smart contract functionality. Ether (Abbreviation: ETH is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software. Ethereum was conceived in 2013 by programmer Vitalik Buterin. Additional founders of Ethereum included Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin. In 2014, development work began and was crowdfunded, and the network went live on 30 July 2015.[7] Ethereum allows anyone to deploy permanent and immutable decentralized applications onto it, with which users can interact.Decentralized finance (DeFi) applications provide financial instruments which do not directly rely on financial intermediaries like brokerages, exchanges, or banks. This facilitates borrowing against cryptocurrency holdings or lending them out for interest. Ethereum also allows users to create and exchange non-fungible tokens (NFTs), which are tokens that can be tied to unique digital assets, such as images. Additionally, many other cryptocurrencies utilize the ERC-20 token standard on top of the Ethereum blockchain and have utilized the platform for initial coin offerings. On 15 September 2022, Ethereum transitioned its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS) in an upgrade process known as "the Merge". This has cut Ethereum's energy usage by 99%.

What is NFT?

NFTs or Non-Fungible Tokens are a kind of cryptocurrency that represents a one-of-a-kind digital asset or unique piece of artwork. Fiat and cryptocurrencies are mainly used for transactional purposes and are fungible, which means each unit can be interchanged.
Non-fungible tokens (NFTs) are assets that have been tokenized via a blockchain. They are assigned unique identification codes and metadata that distinguish them from other tokens. NFTs can be traded and exchanged for money, cryptocurrencies, or other NFTs—it all depends on the value the market and owners have placed on them. For instance, you could use an exchange to create a token for an image of a banana. Some people might pay millions for the NFT, while others might think it worthless. Cryptocurrencies are tokens as well; however, the key difference is that two cryptocurrencies from the same blockchain are interchangeable—they are fungible. Two NFTs from the same blockchain can look identical, but they are not interchangeable.
