It is promising to establish a truly decentralized, transparent, and accountable environment, where blockchain and other cutting-edge technologies will play an essential role. Despite the benefits and great potential of blockchain, current blockchain technologies still suffer from many severe problems, e.g., insufficient trust and security, vulnerability to attacks, low efficiency, poor scalability, low throughput, high energy consumption, privacy leakage, and threats caused by dishonest behaviors. Hence, there is an urgent demand for blockchain evolution, including its architecture, consensus mechanism, incentive mechanism, as well as the theories to integrate blockchain with other emerging technologies, such as machine learning and optimization algorithms. The recent advances in artificial intelligence have offered opportunities to detect anomalies and optimize resources. Furthermore, incentive mechanisms boost the participation willingness of system entities and promote intrinsic trust for blockchain, thereby greatly enhancing system security. Obviously, the evolution of blockchain in architecture, intelligence, and incentive will further extend its applications to wider fields.<o:p class="ContentPasted0" style="word-break: break-word !important;"></o:p></span></p><p class="MsoNormal" style="margin-top: 0px; margin-bottom: 0px; background-color: rgb(255, 255, 255); font-family: 微软雅黑, Verdana, "Microsoft Yahei", SimSun, sans-serif; line-height: 22.4px; text-align: justify; word-break: break-word !important;"><span lang="EN-US" class="ContentPasted0" style="margin: 0px; word-break: break-word !important;"> </span></p><p class="MsoNormal" style="margin-top: 0px; margin-bottom: 0px; background-color: rgb(255, 255, 255); font-family: 微软雅黑, Verdana, "Microsoft Yahei", SimSun, sans-serif; line-height: 22.4px; text-align: justify; word-break: break-word !important;"><span lang="EN-US" class="ContentPasted0" style="margin: 0px; word-break: break-word !important;">This special issue aims to bring together recent advances in new architecture, algorithms with intelligence, incentive mechanisms, and so on for innovating blockchain to improve its overall performance. It will also consider peer-reviewed journal versions (at least 30% new content) of top papers from IEEE Blockchain 2022, which is scheduled to take place in Espoo, Finland, 22-25 August 2022. The new content must be in terms of intellectual contributions, technical experiments, and findings. Any manuscript submitted to this special issue not be published or currently submitted for publication elsewhere. Contributions arising from papers given at other conferences are also welcome but should be substantially extended and should cite the conference paper where appropriate. The differences should also be explicitly outlined in the accompanying cover letter.<o:p class="ContentPasted0" style="word-break: break-word !important;"></o:p></span></p><h1 style="background-color: rgb(255, 255, 255);
