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.

What is Tron? Tron's mission is to build a truly decentralized internet and aims to be the largest blockchain-based operating system in the world, known as the TRON protocol. The TRON protocol will offer high scalability, high availability, and high throughput computing to serve decentralized applications via smart contracts. Ethereum EVM-based smart contracts will be compatible and deployable on the TRON network as such Solidity developers do not have to rewrite their applications. Why Tron? Since TRON protocol does not rely on proof of work or mining, instead governed by nodes located around the world, it is decentralized while providing high throughput for transactions on the blockchain. This is suitable for dapps that require high speed transactions especially games. There are a number of tokens already issued on the TRON network and the decentralized exchanges TRX.market has launched. On July 24th 2018, TRON acquired BitTorrent, one of the largest P2P file sharing protocol. As a result of the acquisition, BitTorrent Token (BTT) was launched as the cryptocurrency to power the economics on the BitTorrent network. The Token will be used to inceltivize file sharing and storage within the network.
