This book focuses on progress, concerns and approaches of blockchain application. It summarizes basic concepts, principles and standardization of blockchain technology, as well as the status of blockchain application and industry. It provides an ecology model and an evaluation method for blockchain applications and analyses the governance of blockchain applications. It presents application values and practices in financial services, logistics, government service, culture and education, and people's livelihood and includes analysis of scenarios and use cases. This book is a summary of the experience of more than 20 experts from enterprises and institutions active in the blockchain industry. It provides a panorama of blockchain applications for users, technology and service providers, application developers and operators and supervisors.

This book constitutes the refereed proceedings of the 11th International Symposium on Algorithmic Game Theory, SAGT 2018, held in Beijing, China, in September 2018. The 19 full papers presented together with 6 short papers and 5 plenary talks were carefully reviewed and selected from 54 submissions. The papers cover various important aspects of algorithmic game theory including market equilibrium, auctions and applications, two sided markets, cake-cutting, cooperative games, voting games, multi-agent scheduling, price of stability, various mechanism design problems: online-dynamics and multi-stages as well as revenue maximization and resource allocation and applications.

This book constitutes the refereed proceedings of the Third International Workshop on Internet and Network Economics, WINE 2007, held in San Diego, CA, USA, in December 2007.

The 61 revised full papers presented together with 4 invited talks were carefully reviewed and selected from numerous submissions for inclusion in the book. The papers are organized in topical sections on equilibrium, information market, sponsored auction, network economics, mechanism design, social networks, advertisement pricing, computational general equilibrium, network games, and algorithmic issues.

WINE 2005, the First Workshop on Internet and Network Economics (WINE 2005), took place in Hong Kong, China, December 15-17, 2005. The symposium aims to provide a forum for researchers working in Internet and Network Economic algorithms from all over the world. The final count of electronic submissions was 372, of which 108 were accepted. It consists of the main program of 31 papers, of which the submitter email accounts are: 10 from edu (USA) accounts, 3 from hk (Hong Kong), 2 each from il (Isreal), cn (China), ch (Switzerland), de (Germany), jp (Japan), gr (Greece), 1 each from hp. com, sohu. com, pl (Poland), fr (France), ca (Canada), and in (India). In addition, 77 papers from 20 countries or regions and 6 dot. coms were selected for 16 special focus tracks in the areas of Internet and Algorithmic Economics; E-Commerce Protocols; Security; Collaboration, Reputation and Social Networks; Algorithmic Mechanism; Financial Computing; Auction Algorithms; Online Algorithms; Collective Rationality; Pricing Policies; Web Mining Strategies; Network Economics; Coalition Strategies; Internet Protocols; Price Sequence; Equilibrium. We had one best student paper nomination: "Walrasian Equilibrium: Hardness, Approximations and Tracktable Instances" by Ning Chen and Atri Rudra. We would like to thank Andrew Yao for serving the conference as its Chair, with inspiring encouragement and far-sighted leadership. We would like to thank the International Program Committee for spending their valuable time and effort in the review process.

This book constitutes the proceedings of the 13th International Workshop on Frontiers in Algorithmics, FAW 2019, held in Sanya, China, in April/May 2019. The 15 full papers presented in this volume were carefully reviewed and selected from 21 submissions. The workshop provides a focused forum on current trends of research on algorithms, discrete structures, and their applications, and brings together international experts at the research frontiers in these areas to exchange ideas and to present significant new results.

This book constitutes the refereed proceedings of the Third International Frontiers of Algorithmics Workshop, FAW 2009, held in Hefei, Anhui, China, in June 2009.
