title: Blockchain Identity
description: "Why Blockchain for Identity? + Assorted Blockchain ID Initiatives"
excerpt: "Traditional identity systems typically suffer from single points of failure, lack of interoperability, and privacy issues such as encouraging mass data collection and user tracking. Blockchain technology has the potential to support novel data ownership and governance models with built-in control and consent mechanisms, which may benefit both users and businesses by alleviating these concerns; as a result, blockchain-based IDMSs are beginning to proliferate."

* [NIST CYBERSECURITY WHITE PAPER] [**_A Taxonomic Approach to Understanding Emerging Blockchain Identity Management Systems_**](https://arxiv.org/pdf/1908.00929.pdf) 2019-06-09
> Identity management systems (IDMSs) are widely used to provision user identities while managing authentication, authorization, and data sharing both within organizations as well as on the Internet more broadly. Traditional identity systems typically suffer from single points of failure, lack of interoperability, and privacy issues such as encouraging mass data collection and user tracking. Blockchain technology has the potential to support novel data ownership and governance models with built-in control and consent mechanisms, which may benefit both users and businesses by alleviating these concerns; as a result, blockchain-based IDMSs are beginning to proliferate. This work categorizes these systems into a taxonomy based on differences in architecture, governance models, and other salient features. We provide context for the taxonomy by describing related terms, emerging standards, and use cases, while highlighting relevant security and privacy considerations.

* [Part 3: Blockchange and Identity – The Foundational Use Case](https://blockchan.ge/fieldreport/identity.html) GovLab 2018-11-01
> The contemporary IAM literature focuses on two central types of identity. The first is foundational identity, which is usually equated with legal identity. Here, after collecting attributes, individuals are issued a unique ID that is legally recognized at the national level and can be used to access different services. Legal IDs are almost always issued by the state in a centralized fashion. National ID cards are perhaps the best example of a foundational identity.
>
> The second type is called functional or transactional ID. In this case, a particular entity, public or private, issues individuals or customers a unique ID that is only valid for the specific purposes previously established by the issuing entity. Electoral identities, health or car insurance cards, and ecommerce login credentials are good examples.
* [Blockchain Identity – Success Factors and Challenges](https://www.kuppingercole.com/blog/kuppinger/blockchain-identity-success-factors-and-challenges) 2018-05-16 Martin Kuppinger
> When new things arrive, which are still in the pioneering stage and far from reaching maturity, there is always a lot of discussion. This is even more true for Blockchain Identity, where the massive hype around Blockchains, a long history of clever ideas failing, and a few interesting technical and security challenges come together. During my keynote at this year’s EIC, I addressed the challenges and success factors for Blockchain ID as well. That led to a discussion on Twitter about whether some of these success factors are contradictory.

> Blockchains possess unique properties that can be used to build systems that significantly impact our world. Perhaps no area of utilization, besides raw value exchange, is as intriguing as decentralized identity. In this talk we will discuss how blockchain-anchored decentralized identity can be used as a substrate for secure, user-centric apps and services.

> Blockchain technology could function as the foundation of such system being a network for decentralized trust and exchange. Because everyone can participate as issuer or acquirer (and both), there are low adoption barriers and low costs. This allows new business opportunities for governments, banks and other authorities and more transparency and control for end-users.

> Most digital identity systems are centralized (e.g., in big government or technology organizations) or individualistic (e.g., in most blockchain projects). However, being in the world is fundamentally social and intersectional — we are all part of networks. So how might we formalize digital identity in a way that better reflects this complex reality? This panel with leading social technology and computer researchers explores more robust digital identity approaches and potential application areas in political economies.

> This report looks at the ongoing exploration of blockchain technology by governments. The analysis of a group of pioneering developments of public services shows that blockchain technology can reduce bureaucracy, increase the efficiency of administrative processes and increase the level of trust in public recordkeeping. Based on the state-ofart developments, blockchain has not yet demonstrated to be either transformative or even disruptive innovation for governments as it is sometimes portrayed. Ongoing projects bring incremental rather than fundamental changes to the operational capacities of governments. Nevertheless some of them propose clear value for citizens. > What most people want but don’t have the terms to describe is respectful digital relationships.

When writing policy, you need a succinct model which is clear enough for subsequent interpretation. To do this, you need conceptual buckets to drop things into. Yes, this model is likely to change, but it’s my best and latest crack at it to synthesize the complex world of digital credentials with an abstraction that might be useful to help us align existing solutions while adopting exciting new capabilities.

> The ability to prove one’s identity is increasingly recognized as the basis for participation in social, political, economic, and cultural life. Yet at least a billion people in developing countries lack any form of officially recognized ID. This problem disproportionally impacts rural residents, poor people, women, children, and other vulnerable groups in Africa and Asia. Digital identity, combined with the extensive use of mobile devices in the developing world, offers a transformative solution to this global challenge and provides public and private sector entities with efficient ways to reach the poorest and most disadvantaged. This discussion paper, divided into three parts, explores the connection between digital identity and sustainable development. Part I illustrates how the use of digital identity promotes efficiency gains, financial savings, social inclusion and access to basic services and rights, with examples from countries that have adopted digital identity systems. The paper then outlines some of the key risks and challenges that must be overcome, specifically in the areas of political commitment, data protection and privacy, cost, and sustainable business models. Part II of the paper lays out the digital identity lifecycle and the roles of public and private sector players, and suggests some key considerations in the design of business models. Finally, Part III of the paper suggests some common principles—including universal coverage, appropriate and effective design, and privacy and data protection—and enablers for maximizing the potential of digital identity to contribute to sustainable development.

> Digitization in the public sector is moving much more slowly, but the transition away from analog is well underway. Smart identity cards, NFC-enabled passports, and digitally stored biometrics are being used by states around the world as they upgrade legacy identity systems. The benefits of digitization for governments— increased efficiencies, lower costs, reduced fraud and corruption, easier surveillance, better data sharing within government—are clear and significant. And for those countries who haven’t yet been able to establish a highly successful analog identity program, the potential of leapfrogging to a fully digital infrastructure is very appealing. Most importantly, the advantages of digital systems have the potential to expand access to identity for otherwise marginalized and vulnerable populations. The benefits of a legal identity for these groups can be tremendous, and the U.N. formally recognized these advantages in 2015 by codifying them into Sustainable Development Goal 16.9: “By 2030, provide legal identity for all, including birth registration.”

> Although this article shall focus on challenges related to identity systems for adult persons in the developed world, we argue that the considerations around data protection and personal data that are applicable in the humanitarian context, such as those elaborated by the International Committee of the Red Cross (Kuner and Marelli, 2017; Stevens et al., 2018), also apply to the general case. We specifically consider the increasingly commonplace application of identity systems “to facilitate targeting, profiling and surveillance” by “binding us to our recorded characteristics and behaviors” (Privacy International, 2019). Although we focus primarily upon the application of systems for digital credentials to citizens of relatively wealthy societies, we hope that our proposed architecture might contribute to the identity zeitgeist in contexts such as humanitarian aid, disaster relief, refugee migration, and the special interests of children as well.

> I’ve written before about the role that the public sector currently has in identity establishment, but not in identity validation. This absence has led to an online ecosystem in the U.S. that depends on non-authoritative information for identity validation. These are some initial thoughts on what an attribute validation service, which provides validation of identity attributes using authoritative public sector sources, could look like.
