论文摘要
区块链是一种新兴的分散数据收集，共享和存储技术，它为各种现实世界中的用例提供了丰富的透明，安全，防篡改，安全和强大的分类帐服务。近年来，有着区块链技术本身以及区块链补充应用的显着发展。大多数现有的调查都限制了区块链或应用程序的几个特定问题的范围，这些范围很难描绘当前巨型区块链生态系统的一般情况。在本文中，我们研究了区块链技术及其在现实世界应用中最活跃的研究主题的最新进展。我们首先回顾了一般区块链系统中共识机制和存储机制的最新发展。然后，在启用区块链的物联网，边缘计算，联合学习以及几种新兴应用程序上进行了广泛的文献，包括医疗保健，COVID-19大流行，社交网络和供应链，在其中讨论了各个详细的特定研究主题。最后，我们讨论了学术界和行业的未来方向，挑战和机遇。
Blockchain is an emerging decentralized data collection, sharing and storage technology, which have provided abundant transparent, secure, tamper-proof, secure and robust ledger services for various real-world use cases. Recent years have witnessed notable developments of blockchain technology itself as well as blockchain-adopting applications. Most existing surveys limit the scopes on several particular issues of blockchain or applications, which are hard to depict the general picture of current giant blockchain ecosystem. In this paper, we investigate recent advances of both blockchain technology and its most active research topics in real-world applications. We first review the recent developments of consensus mechanisms and storage mechanisms in general blockchain systems. Then extensive literature is conducted on blockchain enabled IoT, edge computing, federated learning and several emerging applications including healthcare, COVID-19 pandemic, social network and supply chain, where detailed specific research topics are discussed in each. Finally, we discuss the future directions, challenges and opportunities in both academia and industry.
