The papers in this special section focus on blockchain-based computing services. Blockchain has become a hot research area in academia and industry. A blockchain is a continuously growing list of records of value-transferred transactions maintained by a peer-to-peer network through a distributed consensus mechanism. Blockchain technology has promising characteristics regarding decentralization, persistency, anonymity and auditability that could greatly improve the cost-effectiveness of inter-organization business processes. Blockchain can be applied to many fields of services computing, e.g., big data, cloud computing, digital economy, intelligent contracts, Internet-of-Things, securities, etc.Non-functional innovations in blockchain-based services computing are essential to improving the efficacy of blockchain. These paper focus on presenting novel approaches to integrate blockchain with services computing techniques as well as factual insights on new rising challenges and requirements in achieving this goal.

客座社论：基于区块链的服务计算特刊

本节中的论文重点介绍基于区块链的计算服务。区块链已成为学术界和工业界的热门研究领域。区块链是不断增长的由对等网络通过分布式共识机制维护的价值转移交易记录的列表。区块链技术在去中心化，持久性，匿名性和可审计性方面具有令人鼓舞的特性，可以极大地提高组织间业务流程的成本效益。区块链可以应用于服务计算的许多领域，例如大数据，云计算，数字经济，智能合约，物联网，证券等。基于区块链的服务计算中的非功能性创新对于改善服务质量至关重要区块链的功效。
