Introduction to wallets: MetaMask

Metamask is a digital wallet, known as a wallet, that allows users to interact with the Ethereum network, one of the main blockchain platforms that supports Web3. It is a browser extension or a mobile application that acts as a bridge between traditional web browsers and the Ethereum blockchain, allowing users to manage a blockchain identity and exchange, send, and receive cryptocurrencies and Ether, the native currency of Ethereum. The concept behind Metamask is to simplify access to the world of decentralized applications (dApps) without the need to download the entire blockchain onto one's device. Users can interact with dApps directly from the browser securely, conduct transactions, sign digital messages, and manage their private and public keys. In summary, Metamask is an essential tool in the Web3 ecosystem that provides a user-friendly interface for managing blockchain identities and digital assets, facilitating the entry of non-technical users into the world of cryptocurrencies and dApps.

Ok, all very nice, but what is this Blockchain? 🤨

You're right 😅 imagine the blockchain as a magical book where everyone can write their own stories, but once a story has been written, it cannot be changed or deleted - it stays there forever because it's protected by special magic. Every time someone wants to add a new story, everyone else has to agree that the story is true and that it can be added to the book. Each page of this book contains a list of stories and when the page is full, it is added to the stack of pages already written. Each new page must show the picture of the last page, so we know the exact order of the stories and no one can cheat by trying to change their story later. The beauty is that there isn't just one book in one place. Everyone has a copy and so everyone can see the stories written up to that moment. This means it's very hard for someone to do mischief, like deleting a story or writing a false story, because everyone else can check their book and say: "Hey, this isn't the story we agreed on!" This is the blockchain, a special place where we can keep track of important things like money (which in this magical world are called cryptocurrencies) or important promises, and everyone can trust that everything written there is correct and safe.
