Electronic identification (eID) solutions constitute a critical element in digitalised society. As such, eID has been studied from a variety of perspectives, yet most, if not all existing solutions that have been studied rely on a centralised approach. With the introduction of decentralised technologies such as the blockchain, new avenues for designing eID solutions become feasible. In order to accelerate the creation of blockchain-based eID solutions and their study, this paper offers a comparison of two traditional eID initiatives in Finland and Sweden and one blockchain-based eID initiative in Taiwan. Based on this comparison, we derive insights in the form of design choices for a blockchain-based eID initiative. The findings show that the repertoire for design choices in eID solutions is expanded by the application of the blockchain. These findings are used as a foundation for discussing the design of blockchain-based eID solutions and the need for future research.
