Ethereum is an open-source, public, block chain-based distributed computing platform and operating system featuring smart contract functionality. In this paper, we proposed an Ethereum based electronic voting (e-voting) protocol, Ques-Chain, which can ensure the authentication can be done without hurting confidentiality and the anonymity can be protected without problems of scams at the same time. Furthermore, the authors considered the wider usages Ques-Chain can be applied on, pointing out that it is able to process all kinds of messages and can be used in all fields with similar needs.

FAKE CHECK SCAMS: A BLOCK CHAIN BASED DETECTION SOLUTION
Badis HAMMI1 and Yves Christian Elloh Adja2 1PSB School, Paris, France 2Telecom Paris Tech, Paris, France
Fake checks are one of the most common instruments used to commit fraud against consumers. This fraud is particularly costly for victims, since they generally loose thousands of dollars as well as being exposed to judicial proceedings. Currently, there is no existing solution to authenticate checks and detect fake ones instantly. Instead, banks must wait for a period of more than 48 hours to detect the scam. In this context, we propose a block chain based scheme to authenticate checks. More precisely, our approach helps the banks to share information about provided checks without exposing the banks’ customers’ personal data. A proof of concept of our scheme was realized using Python language and relying on Name coin block chain.
