英文摘要	Blockchains are increasingly used in the collaboration between business as a trusted distributed ledger. Coping with massive data transactions raises the requirement of real-time safety of blockchains. The celebrated Raft protocol has limitations of being a consensus protocol for permissioned blockchains where a strong consistency is needed between clients and servers. In this work, we propose a new consensus protocol called Dynasty which ensures the real-time safety and the liveness under all non-Byzantine conditions. We design and implement a three-layer permissioned blockchain framework which tolerates f failures with 2f+1 correct servers based on Dynasty. We demonstrate the blockchain as a service in an application of used-vehicle trading management and evaluate the performance of the blockchain framework in terms of throughput and latency. Experimental results show that while the latency in different scales of the system increases as expected, the number of committed transactions per second stabilizes at a point within less than 8% difference after a warming-up period.
