Blockchain technology offers a means to secure data transfer between a network of peers. Current designs of blockchain solutions tend to emphasize specific applications, such as financial transaction or sensor data acquisition. Research in blockchain include focuses in consensus methods, implementation frameworks, as well as proof of concept; the wide variance of these areas indicates the flexibility inherent in blockchain design. The decentralized and/or distributed nature of blockchain makes it an attractive match for managing the Internet of Things (IoT), a catch-all phrase to convey the idea that more and more devices are being built with the capability to communicate autonomously using networks such as the public Internet. Projections for IoT device numbers reach the scale of billions within the next several years. For such an event to be feasible without catastrophic security risk, IoT needs to be made scalable, secure, and have low transaction latency. Blockchain could provide the answer to all three challenges. Furthermore, since data can have different requirements for privacy, latency, or authenticity dependent upon the application, a blockchain could be tailored to reflect the needs of the data transfer. Rather than focus on a large selection of blockchain solutions, a singular solution would improve interoperability between networks. A blockchain solution needs to be flexible in order to cater to the diversity of an IoT ecosystem. This thesis proposes the potential of a secure, global IoT network by means of a self-tailoring blockchain solution and suggests possible first steps toward such a world.
