Bitcoin and Lightning Network on Raspberry Pi - Harris Brakmic - Bog - APress - Plusbog.dk

Bitcoin and Lightning Network on Raspberry Pi - Harris Brakmic - Bog - APress - Plusbog.dk

Compile and run Bitcoin full nodes, lightning nodes, and user-friendly web-apps that help abstract the complexities of Bitcoin. This book not only explains the tools and techniques to help readers build their own banks and banking apps, but it also tells a story. Starting with the origins of Bitcoin-what it is and why we need it-find out what its strengths and limitations are. Understand the nature of mining and why so much energy is put into it. The blockchain itself will be reviewed, as well, and compared to other options such as a normal SQL database or a simple spreadsheet. With this book, you can control Bitcoin wallets via RPC commands on a Raspberry Pi. Configure, compile, and run two implementation of the Lightning Network-compatible daemons: LND and c-lightning. And employ user-friendly web apps that abstract the complexities of Bitcoin/Lightning-Network. The Internet of Information is currently transitioning to the Internet of Things, which in turn may well be followed by the Internet of Value (or Money). However, there is no evolution without happy users and Bitcoin will never reach the same heights like the original internet without having offered "useful" and "easy to use" tools. Just like nobody would ever want to use UUCP to send messages via web the same applies to current cryptocurrency tools. These are hard to use and very unforgiving. But, the evolution doesn''t stop here and many easy-to-use tools are already available. We will meet some of them when building apps for the Lightning Network, a new technology running on top of Bitcoin''s blockchain that makes it possible to generate billions of transactions within a single second. What You''ll Learn - Control Bitcoin wallets via console RPC commands - Run two implementation of the Lightning Network compatible daemons - Simplify the complexities of Bitcoin and the Lightning network with user-friendly web apps Who This Book Is For This book is for Makers familiar with the basics of Linux command line processes.

A Brief Introduction to Web3 - Shashank Mohan Jain - Bog - APress - Plusbog.dk

A Brief Introduction to Web3 - Shashank Mohan Jain - Bog - APress - Plusbog.dk

Journey into the world of Web3-based application development, its related protocols, and its usage in developing decentralized applications. This book will explain how programmable blockchains are revolutionizing the world of web applications, which can be run on decentralized platforms or peer-to-peer networks like IPFS. You'll start with an introduction to decentralization with a focus on blockchain implementations like Ethereum and Bitcoin. You'll then learn to develop simple decentralized applications (dApps) using Solidity, the language used for developing apps with Ethereum as well as smart contracts, wallets, gateways and NFTs. This book also covers how security and scale are addressed by L2 networks for scaling Bitcoin and Ethereum blockchains. A Brief Introduction to Web3 is your go-to guide for setting up simple Web3 applications using the Ethereum blockchain programming model. WhatYou Will Learn Build NFT tokensExamine Web3 differs from Web2-based applicationsUnderstand the fundamentals of blockchain and the corresponding data structures around itSee how consensus and trustless computing can be performed using blockchain Use Solidity and Truffle to build Web3 applications Who This Book Is ForSoftware developers and architects who are looking to hone their skills in dApps and web3 applications developed on sound principles of decentralized computing.
