Book Description
This book focuses on conducting a comprehensive analysis of blockchain scalability serving large-scale application scenarios, from the “what, why, how” three perspectives, layer by layer. Gathering the latest state-of-the-art research advances in the area of key issues and technologies for blockchain scalability, it also presents some special and exciting insights on the existing and future blockchain scalability. Despite blockchain’s merits of decentralization, immutability, non-repudiation, and traceability, the current blockchain has faced a serious scalability bottleneck. The scalability bottleneck problem is mainly manifested in two aspects: low-performance efficiency and difficulty in functional extension. First, the security and reliability of the blockchain system come from the fact that most nodes of the whole network participate in a distributed consensus to maintain the ledger. The high-cost consensus mechanism makes limited performance of blockchain, and there is a big gap between the actual large-scale application system. In addition, in order to ensure the security of a single blockchain system, data between different blockchain systems are relatively isolated, making it difficult for assets and data to interact. This book explores the scalability of blockchain in depth, proposes meaningful approaches to the problems mentioned above, and builds an original theoretical system of blockchain scalability. It describes the root of blockchain scalability problems, mainstream blockchain performance, the classification of existing scalability problem solutions, and some exciting sharding-based approaches. It also includes open issues and future directions to scale blockchain for complex practical application scenarios. As such, this book will be a valuable resource for students, researchers, engineers, and policymakers working in various areas related to blockchain scalability, which is also of great significance for understanding and solving the bottleneck of blockchain scalability and realizing the practical large-scale commercial application of blockchain.

Book Description
This practical new book offers the distributed-computing fundamental knowledge for individuals to connect with one another in a more secure and efficient way than with traditional blockchains. These new forms of secure, scalable blockchains promise to replace centralized institutions to connect individuals without the risks of user manipulations or data extortions. The techniques taught herein consist of enhancing blockchain security and making blockchain scalable by relying on the observation that no blockchain can exist without solving the consensus problem. First, the state-of-the-art of consensus protocols are analyzed, hence motivating the need for a new family of consensus protocols offering strong (deterministic) guarantees. Second, a didactic series of classic blockchain vulnerabilities is presented to illustrate the importance of novel designs better suited for the adversarial environment of open networks. These cutting-edge solutions are illustrated through the Redbelly blockchain design, which solves a different problem from the classic Byzantine consensus problem of 1982 and which delivers—in the modern blockchain context—high performance at large scale. Topics and features: Covers the combination of security and distributed computing to devise the new generation of blockchains Shows how blockchain has shed new light on decades of research in distributed systems Provides instruction on the security needed by the industry to use blockchains in production Explains didactically the necessary ingredients to make blockchain efficient at large scale Helps fill the gap of knowledge in the highly demanded blockchain sector This unique volume contains the building blocks to design secure and scalable blockchains. As such, it is dedicated to developers, application designers, and computer scientists and requires only a minimal undergraduate level in mathematics and computer science. Vincent Gramoli is an Australian Research Council Future Fellow at the University of Sydney and the Chief Technology Officer of Redbelly Network. He teaches the Blockchain Scalability course on Coursera.

Book Description
A blockchain is a distributed public ledger that records transactions in a series of linked blocks that can be accessed by anyone. Before being added to the chain, the data (block) is time-stamped and verified. Each block builds upon the data in the one before it. The data is very difficult to forge due to the mathematical complexity of the storage system. The legacy of cryptocurrencies has helped turn the cryptographic term "blockchain" into a trendy catchphrase. A lot of people think blockchain is the same thing as cryptocurrencies. The opposite is true. Blockchain is the underlying technology behind cryptocurrencies, but its uses extend well beyond that. Blockchains may be considered for use in situations requiring the validation, auditing, or exchange of data. Here, we survey the literature on integrating blockchain with machine learning, and show that the two may work together successfully and efficiently. Machine learning is an umbrella word that includes a wide range of techniques, such as traditional ML, DL, and RL. As a distributed and append-only ledger system, the blockchain is a natural instrument for sharing and processing large data from multiple sources thanks to the inclusion of smart contracts, which is a crucial component of the infrastructure necessary for big data analysis. When it comes to training and testing machine learning models, blockchain can keep data secure and promote data exchange. In addition, it paves the way for the creation of timely prediction models using several data sources by leveraging distributed computing resources (like IoT). This is crucial for deep learning processes, which need a lot of processing time. However, distributed systems are more difficult to monitor and regulate than centralized ones, and blockchain systems will create a massive quantity of data from a variety of sources. The best blockchain mechanism designs need accurate data analysis and predictions of system behaviors. Data verification, as well as the detection of harmful assaults and dishonest transactions on the blockchain, may be aided by machine learning. There is a lot to gain from studying how to merge the two technologies from different perspectives.

Book Description
Since its inception in late 2008, Bitcoin has enjoyed a rapid growth, both in value and in the number of transactions. Its success is mostly due to innovative use of a peer-to-peer network to implement all aspects of a currency's lifecycle - from creation to its transfer between users. Bitcoin offers cash-like transactions that are near-instantaneous and non-refundable, while at the same time allowing truly global transactions, processed at the same speed as local ones. It offers a public transaction history, enabling trustless auditability, and it introduces many new and innovative use-cases such as smart property, micropayments, contracts, and escrow transactions for dispute mediation. However, the same features that make Bitcoin attractive for its end-users are also its main limitations. Its decentralized nature limits the number of transactions and the speed at which transactions can be performed and confirmed. The problem with the slow confirmations is compounded with the semantics of the confirmations which are not final, requiring multiple confirmations and further delaying acceptance of a transaction. In the first part of the thesis we analyze whether the current Bitcoin protocol scales and what the scalability limits are. We find that Bitcoin does not scale, because its synchronization mechanism, the blockchain, limits the maximum rate of transactions the network can process. In order to address the scalability problem we propose Duplex Micropayment Channels, which increase the rate at which Bitcoin transfers can be performed by several orders of magnitude, by moving the transfers off the blockchain and using the blockchain solely for dispute mediation. Another form of scalability problem is the fact that more and more blockchain based applications are being created, eachwith their own small isolated blockchain, and vulnerable to attacks. We present PeerCensus, a subsystem that acts as a certification authority, manages peer identities in a peer-to-peer network and does not store application specific data in the blockchain. Using PeerCensus, any number of applications can share a single blockchain, decoupling confirmations from block generation rate and enhancing Bitcoin and similar systems with strong consistency. Being a relatively new technology, Bitcoin has a number of new security challenges and innovative properties. We analyze these properties and challenges in the second part of the thesis. The first novel property is that the transaction history, in the form of the blockchain, is public and accessible by anyone. Making use of the open nature of the blockchain, we were able to dispell claims by MtGox, once the world's largest Bitcoin exchange, that a bug in the Bitcoin protocol was used in a large scale attack to defraud them. We then use the blockchain to build a prototype of an audit protocol that allows a fiduciary, such as a Bitcoin exchange, to demonstrate that its assets cover its liabilities, without resorting to trusted third parties. Bitcoin also shifts the responsibility of managing and securing funds from a trusted third party to the end-user, which may not have the necessary tools to protect her funds. We show how a merchant may accept fast-payments, i.e., transactions without waiting for confirmations, with reasonable security against doublespending attacks by observing how transactions propagate in the network. Finally, we present a prototype of a secure device that stores private keys in tamper resitant storage and allows the user to independently verify a payment before authorizing it.
