Abstract
Since the emergence of the Bitcoin cryptocurrency, the blockchain technology has become the new Internet tool with which researchers claim to be able to solve any existing online problem. From immutable log ledger applications to authorisation systems applications, the current technological consensus implies that most of Internet problems could be effectively solved by deploying some form of blockchain environment. Regardless this ‘consensus’, there are decentralised Internet-based applications on which blockchain technology can actually solve several problems and improve the functionality of these applications. The development of these new blockchain-based solutions is grouped into a new paradigm called Blockchain 3.0 and its concepts go far beyond the well-known cryptocurrencies. In this paper, we study the current trends in the application of blockchain on the paradigm of Public Key Infrastructures (PKI). In particular, we focus on how these current trends can guide the exploration of a fully Decentralised Identity System, with blockchain as be part of the core technology.
Highlights
The need to establish unique identities for the Internet has existed for a very long time insofar as users need to interact with different products and services, and to validate the users’ identities with an authority, a server or a government entity
This implies the study of decentralised identity concepts and how they are reflected in different systems where users have most of the control of the process of creating and storing their certificates
The analysis of the current trends on the application of blockchain in identity management proves that the technology is used basically like a log of other identity interactions
Summary
The need to establish unique identities for the Internet has existed for a very long time insofar as users need to interact with different products and services, and to validate the users’ identities with an authority, a server or a government entity. None of these surveys described the way the blockchain could be used as a management tool in the so-called Blockchain 3.0 technologies, which are being used to solve current problems beyond cryptocurrencies and financial affairs [11]. This implies the study of decentralised identity concepts and how they are reflected in different systems where users have most of the control of the process of creating and storing their certificates.
