The general assumption in the West is that there still is an inherent difference between persons and things. This divide informs how “the human” and human subjectivity are constructed as distinct from all others. Recently, the distinction has been challenged in posthumanist theory, where it has been argued that the divide between human and nonhuman agents—or rather, bodies—is always an effect of a differential set of powers. For this reason, the boundaries between human and nonhuman are always in flux. As posthumanist theorists have argued, this change in boundaries may be specifically visualized in relation to digital technology. Today, such technologies obfuscate the boundaries between persons and things, and the extensive utilization of smartphones, social media, and online search engines are just three common examples.
Blockchain technology is often discussed and theorized in relation to cryptocurrencies such as Bitcoin. Its quality as a technology that produces advanced encryption keys between objects, however, also makes it interesting to those who seek to connect physical objects to digital elements. The reason for this is that the link between objects needs to be 'secure' from undesired external interference. In relation to such interests, blockchain has been identified as a highly attractive technology to support the general digitalization of society towards the Internet of Things, smart cities etc. In extension, the implementation of blockchain technology implies that it may work as a tool that has the capacity to direct which objects may/may not interact with each other. The 'ledger of everything' that blockchain may possibly produce as regards the 'Internet of Everything' is even suggested to make humans and other intermediary technologies redundant. In this essay, I argue that in order to sustain legal critique when the world moves into the next era of digitalization, we need to understand -and question -how technological control operates through e.g. blockchain technology by locking physical and digital elements to each other.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
