With good demonstrations and graphics, this document will assist people in deciding what resources and what parts of a system to place in blockchain and what parts do not need to be. By providing the actual scenarios, it gives good examples of strong and weak systems that can be used.

After discussing various negative tradeoff issues concerning the offloading of blockchain smart contract authorization from constrained Internet of Thing (IoT) devices to a single authorization server (i.e. execution costs, delays, data reduction), authors state their ambition of presenting designs that more effectively perform this task instead utilizing multiple authorization servers (AS). The stated intention for resolving these tradeoffs is to exemplify constrained IoT device interconnection using a decentralized authorization method with multiple blockchains that constitute two interledger mechanisms.
The level of deliberation appears to be meant for those that have already obtained intermediate to advanced knowledge of blockchain, smart contracts, and constrained IoT devices. However, with some additional research, a reader with novice awareness of these subjects would be able to follow and learn more about the aspects of the presented issue. Further, despite a compelling presentation and references listed at the end of the writing, my attention was drawn to the lack of cited sources listed in the article. This absence was initially noted upon reading the Introduction section, which proposed claims of high computation costs, transaction fees, and delays that occur with the utilization of Ethereum as Bitcoin.
I did find the report to be educational as to the various processes involved while implementing blockchain smart contracts in conjunction with constrained IoT devices. What’s more, is I have been persuaded that experimenting with the interconnection of multiple blockchains to improve smart contract efficiency is a worthy pursuit.
