 Marcus asks, why would one use MetaMask, or MyEtherWallet, or MyCrypto? Is it just that they can hold multiple Ethereum-based tokens, or do they have more useful capabilities? MyEtherWallet and MyCrypto are three lightweight clients and wallets. What they do is they don't just implement wallet functionality, they also expose to your browser, or make available to your browser, the Web3 JavaScript interface that allows dApps, decentralized applications, to run in your browser and access the Ethereum network through this wallet, to create transactions, to access contracts, etc. These are more than just wallets, they are wallets and lightweight clients that can expose the application programming interface that allows a web application to access the Ethereum network. Yes, they can hold multiple Ethereum-based tokens, but they can also support web applications that access Ethereum. Sudhakar asks, is the EVM Ethereum wallet and MyST the same thing? If not, what are the differences and how do you install each? These are three different things. MyST is a user interface or dApp browser, so it is a front-end that allows you to access an interface with decentralized application. A dApp browser like MyST is a wallet, a client, and a front-end user interface. MyST is all three of those things. There are a few others. Parity wallet has its own graphical user interface and front-end. MyUthewallet and myCrypto are also in that category. Ethereum wallet is one application that runs within MyST, which is just a simple wallet running as a decentralized application. It is really just a front-end to a simple Ethereum wallet. EVM, the Ethereum virtual machine, is a virtual machine that executes smart contract code that is being compiled into bytecode, which is a bit like a machine language. An EVM runs inside every Ethereum client and is used to validate every Ethereum transaction. It is also run by miners in order to validate transactions, and it is how smart contracts get executed. MyST and Ethereum wallet use a client, in the case of MyST. For example, they use the Go Ethereum client, or GEF, and that client has within it an EVM for validating transactions and executing smart contracts. There is an EVM inside GEF, which is inside MyST. Perhaps that helps you understand some of the differences.
