Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

'Developed by Luxcore, LUX (LUX Coin) is a hybrid cryptocurrency utilizing both proof-of-stake and proof-of-work algorithms to enhance blockchain security and decentralization. Luxcore's hybrid consensus model imploys masternodes to provide specialized functions and further secure the chain while providing additional rewards to coin holders. The LUX blockchain enables developers to utilize smart contracts and decentralized applications. Luxcore continues to develop products for the LUX blockchain including Luxgate (a truly trustless, peer to peer decentralized exchange) and Luxedge (a decentralized software development platform and repository). LUX was created in 2017 as a fork of the Bitcoin codebase, but it has grown to not only keep up with new technologies in the cryptocurrency space, but has aimed to introduce new innovations and services to the broader crypto community with cross-chain and decentralized solutions.'
