I would highly recommend this paper to anyone that would like to understand the basics of the underlying technologies that support a blockchain. As far as discussion around blockchain and IoT, the paper was a little sparse. I would recommend it as a good overview of the topic, and perhaps a good resource to find more in-depth papers on blockchain and IoT in the References section.

Authors open their discussion by explaining that blockchain has grown from digital currency to smart contract utilization by a wide range scope of industries. It is then brought to light that, with this change, there is an issue of blockchain smart contract research not being collocated for concentrated review by experts, and it is proclaimed that this document will explore research gap issues related to this.
The report delves into a cited example of Nakamoto’s original proposal that the inherent processes of blockchain could be utilized to avoid duplicate digital spending, which then leads into an evaluation of how various entities have begun to utilize this concept within the format of smart contracts. A breakdown ensues of how the related issues of duplication, Sybil-attack, transaction isolation, and immutability are being resolved by blockchain industry leaders.
I liked the way the article followed this by giving referenced examples of the tokenization of real-world assets and virtual assets, which brought together the initial ideas presented before diving into the final sections concerning the analysis of four classes of smart contract issues: codifying, security, privacy, and performance. The paper tied this together at the end with mentions of various researched problem-solving proposals, and a conclusion that demonstrates further comprehensive studies need to occur for blockchain-based smart contract technology to be universally actualized.
It seems to me that this article would be helpful to a wider audience, as ideas are presented simply enough that one could consider the effectiveness and foresee possible issues concerning blockchain use across multiple applications.
