Take advantage of Bitcoin’s underlying technology, the blockchain, to build massively scalable, decentralized applications known as dapps. In this practical guide, author Siraj Raval explains why dapps will become more widely used—and profitable—than today’s most popular web apps. You’ll learn how the blockchain’s cryptographically stored ledger, scarce-asset model, and peer-to-peer (P2P) technology provide a more flexible, better-incentivized structure than current software models. Once you understand the theory behind dapps and what a thriving dapp ecosystem looks like, Raval shows you how to use existing tools to create a working dapp. You’ll then take a deep dive into the OpenBazaar decentralized market, and examine two case studies of successful dapps currently in use. Learn advances in distributed-system technology that make distributed data, wealth, identity, computing, and bandwidth possible Build a Twitter clone with the Go language, distributed architecture, decentralized messaging app, and peer-to-peer data store Learn about OpenBazaar’s decentralized market and its structure for supporting transactions Explore Lighthouse, a decentralized crowdfunding project that rivals sites such as Kickstarter and IndieGogo Take an in-depth look at La’Zooz, a P2P ridesharing app that transmits data directly between riders and drivers

As an alternative to traditional client-server systems, Peer-to-Peer (P2P) systems provide major advantages in terms of scalability, autonomy and dynamic behavior of peers, and decentralization of control. Thus, they are well suited for large-scale data sharing in distributed environments. Most of the existing P2P approaches for data sharing rely on either structured networks (e.g., DHTs) for efficient indexing, or unstructured networks for ease of deployment, or some combination. However, these approaches have some limitations, such as lack of freedom for data placement in DHTs, and high latency and high network traffic in unstructured networks. To address these limitations, gossip protocols which are easy to deploy and scale well, can be exploited. In this book, we will give an overview of these different P2P techniques and architectures, discuss their trade-offs, and illustrate their use for decentralizing several large-scale data sharing applications. Table of Contents: P2P Overlays, Query Routing, and Gossiping / Content Distribution in P2P Systems / Recommendation Systems / Top-k Query Processing in P2P Systems

Blockchain technology and the invention of smart-contracts running on it have given rise to Decentralized Finance. At the time of its birth, DeFi was seen as a response to the 2008 crisis and a hope to democratize finance. By eliminating the role of intermediaries and fluidifying property through tokenization, finance would become accessible to all. To overcome all the obstacles it faced (volatility, security issues, distrust etc.), DeFi had to find original ways to develop, by leveraging sociologically diverse communities of enthusiastic developers, users and investors from all over the world. In particular, it has distinguished itself in the fields of communication, marketing and community building through an original use of social networks and messaging tools. We have specifically emphasized these latter aspects, based on our professional experience and interviews with experts working in the field. It appears that DeFi is potentially interesting for companies. Indeed, Blockchain technology is generalizable to many other areas of economic activity beyond finance. Moreover, the DeFi communities foreshadow the communities of entrepreneurs and users/consumers of the future Web3.0. DeFi is the manifestation of a new era of the Internet. Due to key elements of blockchain and smart contracts, the value of data could be wrested from the hands of Internet giants, that control the ad market, and be restituted to businesses and consumers. Through the direct relationship with the consumer, this technology is becoming a powerful tool for optimizing business operations, reducing costs and creating value. Businesses will have to reconsider relationship with their customers, in a spirit of community and direct interaction with them (which blockchain allows, i.e. through remuneration of the user/customer). However, if blockchain technology is mature, its use is still too amateurish. In this context, it is crucial to rely on recognized professionals, because a hasty implementation can lead to serious risks for the reputational and financial integrity of companies. Experts we have interviewed have emphasized this key issue. On the one hand, a business with significant capital can invest heavily in Web3.0 and can develop its own blockchain solutions to stay ahead of its competitors. On the other hand, a small business cannot do the same. With less technical and financial capital, the small business is currently only able to implement technologies that are not very advanced and whose utilization carries risks. But the situation may change rapidly in the future. Get this book and you will learn more on blockchain and decentralized finance.

The dominance of trusted intermediaries could be weakened by blockchain, a distributed ledger technology, one of the functions of which is to constitute timestamped proofs by replacing inter-individual trust with algorithmic trust. Blockchain self-executing smart contracts allow us to rethink the practice in the domain of e-commerce, interbank communication, fundraising (and ICOs), justice (timestamping evidence, acts authenticated by blockchain) and businesses in numerous sectors (entertainment, AI, health, real estate, tourism, transport, etc.) which attempt to propose new services by benefiting from blockchains. This book aims to put into perspective the technical innovations and the uses brought about by blockchain, by identifying that which has a medium- or long-term impact, all while taking into account the social, economic, judicial and administrative resistances that are likely to develop.

What Is Decentralized Finance Decentralized Finance is a blockchain-based form of finance that does not rely on central financial intermediaries such as brokerages, exchanges, or banks to offer traditional financial instruments, and instead utilizes smart contracts on blockchains, the most common being Ethereum. There are some major advantages of using DeFi, including cost, speed and security. Anyone with an internet connection has access to blockchains and cryptocurrencies. Users are able to make trades and move their assets whenever they want without having to wait on bank transfers or pay bank fees. Decentralized finance is quickly rising as a more secure, more transparent, and more efficient alternative to traditional financial services. By eliminating the need for centralized financial institutions, we create a more open and trustworthy financial system, and one that's far more accessible. Therefore, decentralized finance is a very near equivalent of an apocalyptic event for the traditional financial institutions.
