The authors chose to look at a collection of sixty-four different studies done concerning the usage of smart contracts in blockchain technology. The systematic mapping study was designed to offer a broader perspective that focused on trends, methods and approaches.
According to the authors the most common issue relating to smart contracts themselves revolves around the programmability of the smart contracts. The study also attempts to identify smart contract research gaps such as scalability, performance issues and the lack of studies outside of the Ethereum platform.
The takeaway for me was the combination of factors involving security and privacy. This has been an issue that I have seen repeatedly in my research into blockchain technology and smart contracts in particular. More research needs to be put into place regarding the real world usage of smart contracts.
