Blockchain is increasingly deployed in a broad range of sectors, ranging from banking and finance to manufacturing to energy to transportation, and so on. While many technological and business related blockchain developments and challenges have been identified, many of these engineering and management challenges have not been addressed. The ongoing interest in this topic is also partly evidenced by the large number of submissions we received in this special issue. Of the 200 submissions, only 39 articles were eventually accepted after several rounds of rigorous reviews (i.e., acceptance rate of 19.5%). In this editorial, we report on the findings from the first 36 articles on a broad range of topics (e.g., supply chain, financial technology, Internet of Things, smart city, healthcare, security, privacy, and blockchain building blocks such as consensus algorithms). Hopefully, the findings reported in these 36 accepted articles will provide sustainable solutions for existing and future blockchain systems and platforms.

社论：区块链生态系统——技术和管理的机遇与挑战

区块链越来越多地部署在广泛的领域，从银行和金融到制造业，从能源到运输等等。虽然已经确定了许多与技术和业务相关的区块链发展和挑战，但其中许多工程和管理挑战尚未得到解决。我们在本期特刊中收到的大量投稿也部分证明了对该主题的持续兴趣。200篇投稿中，经过多轮严格审核（即接受率为19.5%），最终只有39篇被接受。在这篇社论中，我们报告了前 36 篇关于广泛主题（例如，供应链、金融技术、物联网、智慧城市、医疗保健、安全、隐私、和区块链构建块，例如共识算法）。希望这 36 篇被接受的文章中报告的发现将为现有和未来的区块链系统和平台提供可持续的解决方案。
