Reputation systems offer a medium where users can quantify the trustworthiness or reliability of individuals providing online services or products. In the past, researchers have used blockchain technology for reputation systems. Smart contracts are computer protocols which have the primary objective to supervise, implement, or validate performances or negotiations of contracts. However, through a systematic literature review, in this paper, we find that the existing literature has not proposed a framework that facilitates the interchangeable use of smart contracts for blockchain-based reputation systems. We adopt a systematic literature review from 30 relevant studies and the data from them were extracted before identifying the research gaps. As a solution to the research gaps, we propose the FarMed framework for creating an intelligent framework that will execute Ethereum smart contact-based reputation systems and develop reliable blockchain-based protocols for transferring reputation values from one provider to another. We briefly explain our proposed framework before concluding with our future work.

信誉系统提供了一种媒介，用户可以在其中量化提供在线服务或产品的个人的可信赖性或可靠性。过去，研究人员将区块链技术用于信誉系统。智能合约是计算机协议，其主要目的是监督，实施或验证合同的执行或谈判。但是，通过系统的文献综述，我们发现现有文献并未提出促进基于区块链的信誉系统可互换使用智能合约的框架。我们对30项相关研究进行了系统的文献综述，并在确定研究空白之前提取了其中的数据。为了解决研究空白，我们提出了FarMed框架，以创建一个智能框架，该框架将执行以太坊基于智能联系的信誉系统，并开发可靠的基于区块链的协议，以将信誉值从一个提供商转移到另一个提供商。在结束我们的未来工作之前，我们将简要解释我们提出的框架。
