| Abstract: | Nowaday, Blockchain system has applied in many different areas, for it decentralized and disintermediation. Utilized a Blockchain system can help peers do interactiviting when they do not actually familiar with each other nor need a third-party credit organization. Permitted Blockchain system are expanded as its own advantage. Compare with original decentralized Blockchain as bitcoin, permitted Blockchain cost significant less and has higher thoughput. And those advantages will help the commercial users developing their own system agilely. Hyperledger Fabric[1], as modular and extensible distributed system, has cyclopedic users. But on their recent KAFKA consensus module, we found a potential attack method. In this paper, we will discuss this kind of potential attack and gives out our solution. And for further, we will introduce the IoV[17], which proposed an mechanism to evaluate the credit to value the trust of peers on the system, and put forward our own calculating method to the IoV combine with our consensus algorithm to make the permitted Blockchain more robustness. |
