Ethereum is a blockchain used as a base for building. Its native coin, Ether (ETH), is used to pay Ethereum gas fees charged for interacting with the Ethereum network. Developers can build decentralized applications (DApps) or tokens on the Ethereum blockchain. Vitalik Buterin published the Ethereum white paper in late 2013, but the blockchain did not launch until 2015 as the product of multiple co-founders, including Buterin. ETH price, or Ethereum price — the price of ETH to USD — rose significantly in the years following 2015. How Ethereum worksThe Ethereum blockchain started as a proof-of-work (PoW) blockchain, relying on Ethereum mining for block production on its network. In this system, miners (computing equipment set up to run automatically) compete to find the answer to a complex puzzle. The winner gets to produce an Ethereum block on the network. Each block is filled with transactions and contains a block reward. The miner that wins a contest to discover the block earns the block reward and the transaction fees associated with the transactions in that block.In 2020, however, Ethereum officially began its transition to Ethereum 2.0, or Eth2 — a lengthy transition aiming to scale the Ethereum blockchain and move to a proof-of-stake (PoS) consensus algorithm. The Ethereum 2.0 blockchain relies on validators staking a minimum of 32 ETH to run and secure the network.Ethereum has smart contract capabilities. Smart contracts are essentially digital contracts that execute a predetermined agreement once certain conditions are reached. Developers can build DApps on the Ethereum blockchain. These DApps can look similar to other applications, with user-friendly front ends that offer features such as asset trading. On the back end, however, DApps run on the Ethereum blockchain via smart contracts. Developers can also deploy a number of different types of tokens on the Ethereum blockchain, such as ERC-20 assets. These ERC-20 tokens are distinct assets, but they run on the Ethereum blockchain. Another example is nonfungible tokens, or NFTs, which are buildable via a different type of Ethereum token — the ERC-721 token standard.How secure is Ethereum? Due to its nature as a blockchain run by numerous participants around the globe — without any main centralized entity controlling it — Ethereum should be quite secure (in a general sense) compared with the centralized solutions of yesterday.Ethereum priceEthereum ran its initial coin offering (ICO) in 2014, prior to the Ethereum blockchain’s launch in 2015. In 2016,
