Summary: People aren't digitally embodied. As a result, their online relationships are anemic. As we think about the kinds of digital identity systems that will help people live authentic online lives, we must build identity systems that give people tools to operationalize rich digital relationships.

Identity is the ability to recognize, remember, and react to people, organizations, systems, and things. In the current web, companies employ many ponderous technological systems to perform those functions. In these systems, we are like ghosts in the machines. We have "accounts" in companies' systems, but no good way to recognize, remember, and react to them or anyone else. We are not digital embodied.

One of the great benefits of embodiment is the ability to form and operationalize rich digital relationships. I've written a lot about the nature of digital relationships.

• Relationships and Identity
• Authentic Digital Relationships
• Ephemeral Relationships
• Operationalizing Digital Relationships
• Relationships in the Self-Sovereign Internet of Things
• The Architecture of Identity Systems
• Are Transactional Relationships Enough?
• Fluid Multi-Pseudonymity

One of the discussions at VRM Day caused me to think about a feature of digital relationships I hadn't considered before. Someone said that if you think about a graph with people (or things, organizations, and so on) as the nodes, the relationships are the edges, like so¹:

In this figure Alice and Bob have a bi-directional relationship. This is how I've normally thought about it and how I'd have drawn it. But in today's discussion, someone said that the relationship is shared and that Alice and Bob both control it. But I realized that viewpoint is too simple. Specifically, Alice and Bob each have a different perspective of that relationship and will use it separately.

For example, imagine that Alice is the cashier at a grocery store and Bob is a customer. Alice gives great service, so Bob seeks her out when he shops. Alice on the other hand has no particular recollection of Bob from encounter to encounter. For Alice, the relationship is ephemeral, but for Bob, it's longer term. The nature of each relationship is different. So, we might look at it like this:

But after discussing it some more, I realized that these relationships aren't independent. They're entangled like this:

In the example I gave above, as Bob seeks out Alice more and more, Alice might come to recognize him and call him by name, changing the nature of her relationship with Bob. And that may influence the nature of Bob's relationship with Alice. Over time, these interactions influence both relationships. So, while Alice and Bob both have control over their relationship with the other, actions by one influence the other.

I frequently say that we don't build identity systems to manage identities, but rather to manage relationships. The problem with contemporary identity systems is that they are all one sided, controlled by one party—almost always a company. As I've said before, people are not digitally embodied and thus have no good way to manage their online relationships. As we strive to build better digital identity systems, I think it's paramount that we build systems that provide people with tools that embody them and provide them with the ability to operationalize their online relationships. These are more than decentralized; they are self-sovereign.

Notes

1. Peer decentralized identifiers (DIDs) are a great technology for creating bi-directional relationships.

Summary: In session after session, attendees at EIC are hearing the message that decentralized identity is the answer to their identity problems.

I'm at European Identity Conference (EIC) this week. I haven't been for several years. One thing that has struck me is how much of the conversation is about decentralized identity and verifiable credentials. I can remember when the whole idea of decentralized identity was anathema here. The opening keynote, by Martin Kuppinger is Vision 2030: Rethinking Digital Identity in the Era of AI and Decentralization. And all he's talking about is decentralized identity and how it's at the core of solving long standing identity problems. Another data point: Steve McCown and Kim Hamilton-Duffy ran a session this morning called Decentralized Identity Technical Mastery which was a hands-on workshop. The rather large room was packed—standing room only.

I attended a couple of sessions on decentralized identity where I didn't know the companies, the speakers, or the specific platforms they were using. The space is too big to keep track of anymore. Identity professionals who were ignoring, or talking down, decentralized identity a few years ago are now promoting it.

This truly feels like a tipping point to me. At IIW, it's identity geeks talking with other identity geeks, so it's no surprise to see lots of discussion about new things. EIC is a different kind of conference. There are about 1000 people here I'd guess. Most of them aren't working on new standards or open source projects. Instead they're the folks from companies who come to conferences like EIC to learn how to solve the problems their organization is facing.

In the keynotes and in numerous sessions, the message that they're hearing is "decentralized identity will solve your problems." Martin closed his talk with the proclamation that "decentralized identity is the new paradigm for identity."

Summary: What is decentralized identity and why is it important? My attempt at a simple explanation.

In Yeah, yeah, yeah, yeah, yeah, nah, Alan Mayo references my recent blog post, Decentralized Identity Comes of Age, and says:

My challenge to the decentralization community is for them (someone) to explain how it works in relatively simple and reasonable terms. I say relative because identity is not simple, so we should not expect simple solutions.

This post is my attempt to do that for Alan and others.

Identity is how we recognize, remember, react to, and interact with other people, organizations, and services. Put another way, identity is about relationships. Online we suffer from a proximity problem. Since we're not near the parties we want to have relationships with, our natural means of recognizing, remembering, and interacting with others can't be used. Digital identity systems are meant to provide us with the means of creating online relationships.

Traditional identity systems have not served us well because they are owned and controlled by companies who build them for their own purposes. The relationships they support are anemic and transactional. We can't use them for any purpose except what their owner's allow.

Decentralized identity systems¹ on the other hand allow you to create online relationships with any person, organization, or service you choose and give you the tools to manage and use those relationships. They help you recognize, remember, react to, and interact with them. The most important tool is a decentralized identity wallet. The world of decentralized identity wallets is still young, but organizations like the Linux Foundation's Open Wallet Foundation give me hope that useful, interoperable wallets are a tool we'll all be able to use soon. They are as foundational to decentralized identity as a browser is to the web.

Besides helping you manage peer-to-peer relationships with others online, wallets hold verifiable credentials, the digital analog to the credentials and cards you carry in a physical wallet. One of the most important aspects of digital relationships is providing information about yourself to those you interact with. Sometimes that information can come from you—it's self-asserted—but many times the other party wants to reliably know what others say about you. For example, if you establish a banking relationship, the bank is legally obligated to verify things like your name and address independent of what you say. Decentralized identity wallets allow you to prove things about yourself using credentials others provide to you. At the same time, they protect your privacy by limiting the information disclosed and forgoing the need for the party you're interacting with to directly contact others to verify the information you provide.

In summary, decentralized identity systems allow you to create digital relationships with other parties independently, without relying on any other organization or service. These relationships are direct, private, and secure. They also provide the means for you to prove things about yourself inside these relationships so that even though you're operating at a distance, you and the other party can have confidence in the relationship's authenticity.

How Does It Work

The preceding paragraphs say what decentralized identity is, and provide its benefits, but don't say how it works. Alan and others will likely want a few more details. Everything I describe below is handled by the wallet. The person using the wallet doesn't need to have any more knowledge of how they work than the operator of a browser needs to understand HTTP and HTML.

The foundation of a peer-to-peer, decentralized online relationship is an autonomic identifier like a peer DID. Identifiers are handles that someone else can use to identify someone or something else online. Peer DIDs can be created by a wallet at will, they're free, and they're self-certifying (i.e., there's no need for a third party). A relationship is created when two identity wallets create and exchange peer DIDs with each other on behalf of their owners. Peer DIDs allow the parties to the relationship to exchange private, secure messages.

There are four primary interaction patterns that wallets undertake when exchanging messages:

1. DID Authentication which uses the DIDs to allow each party to authenticate the other
2. Single-Party Credential Authorization where the same party issues and verifies the credential.
3. Multi-Party Authorization where the credential issuer and verifier are different parties.
4. Generalized Trustworthy Data Transfer which uses a collection of credentials to aid the wallet owner in completing online workflows.

Verifiable credentials make heavy use of cryptography to provide not only security and privacy, but also confidence that the credential data is authentic. This confidence is based on four properties a properly designed credential presentation protocol provides:

1. The identifier of the credential issuer
2. Proof that the credential is being presented by the party is was issued to
3. Proof that the credential has not been tampered with
4. The revocation status of the credential

The credential presentation can do all this while only disclosing the information needed for the interaction and without the verifier having to contact the credential issuer. Not having to contact the issuer ensures the credential can be used in situations with poor connectivity, that the issuer needn't be online, and preserves the credential subject's privacy about where the credential is being used.

A properly designed credential exchange protocol has four important properties:

1. The system is decentralized and contextual. There is no central authority for all credentials. Every party can be an issuer, an owner, and a verifier. The system can be adapted to any country, any industry, any community, any set of credentials, any set of trust relationships.
2. Issuers are free to determine what credentials to issue and whether or not to revoke them.
3. Wallet owners are free to choose which credentials to carry and where and when they get shared. While some verifiers require a specific credential—such as a customs agent requiring a passport—others will accept a range of credentials. Therefore owners can decide which credentials to carry in their wallet based on the verifiers with whom they interact.
4. Verifiers make their own decisions about which credentials to accept. For example, a bar you are trying to enter may accept any credential you have about your date of birth. This means some credentials (e.g., passports, driving licenses, birth certificates) may be much more useful than just for the original purpose for which they were issued.

These properties make a decentralized identity system self sovereign.

Why is Decentralized Identity Important?

Decentralized identity systems are designed to provide people with control, security, and privacy while enhancing the confidence we have in our online relationships. Some time ago, I wrote the following. I think it's an apt way to close any discussion of decentralized identity because unless we keep our eyes on the goal, we'll likely take shortcuts in implementation that fail to live up to their promise.

Presently, people don't have operational relationships anywhere online.² We have plenty of online relationships, but they are not operational because we are prevented from acting by their anemic natures. Our helplessness is the result of the power imbalance that is inherent in bureaucratic relationships. The solution to the anemic relationships created by administrative identity systems is to provide people with the tools they need to operationalize their self-sovereign authority and act as peers with others online. Peer-to-peer relationships are the norm in the physical world. When we dine at a restaurant or shop at a store in the physical world, we do not do so under the control of some administrative system. Rather, we act as embodied agents and operationalize our relationships, whether they be long-lived or nascent, by acting for ourselves. Any properly designed decentralized identity system must provide people with the tools they need to be "embodied" in the digital world and act autonomously.

Time and again, various people have tried to create decentralized marketplaces or social networks only to fail to gain traction. These systems fail because they are not based on a firm foundation that allows people to act in relationships with sovereign authority in systems mediated through protocol rather than by the whims of companies. We have a fine example of a protocol mediated system in the internet, but we've failed to take up the daunting task of building the same kind of system for identity. Consequently, when we act, we do so without firm footing or sufficient leverage.

Ironically, the internet broke down the walled gardens of CompuServe and Prodigy with a protocol-mediated metasystem, but surveillance capitalism has rebuilt them on the web. No one could live an effective life in an amusement park. Similarly, we cannot function as fully embodied agents in the digital sphere within the administrative systems of surveillance capitalists, despite their attractions. The emergence of self-sovereign identity, agreements on protocols, and the creation of metasystems to operationalize them promises a digital world where decentralized interactions create life-like online experiences. The richer relationships that result from properly designed decentralized identity systems promise an online future that gives people the opportunity to act for themselves as autonomous human beings and supports their dignity so that they can live an effective online life.

Notes

1. I prefer the term self-sovereign to decentralized because it describes the goal rather than the implementation, but I'll stick with decentralized here. All self-sovereign identity systems are decentralized. Not all decentralized identity systems are self-sovereign.
2. The one exception I can think of to this is email. People act through email all the time in ways that aren't intermediated by their email provider. Again, it's a result of the architecture of email, set up over four decades ago and the culture that architecture supports.

Anna Mills, Bluesky Social, Nov 13, 2024

The most interesting migration in social media these days is from twitter to Bluesky. Here are two approaches to making it easier: the first is a 'starter pack' on people in AI and education. It makes use of the Bluesky Lists feature or the Bluesky Starter Pack. In the same genre, here's a Tech Media Starter Pack. The second, via Miguel Guhlin, is based on a hashtag with members listed on a Google Docs spreadsheet. It's cleverly done. You have to apply to be listed on the spreadsheet, and to be accepted you have to use the #Edusky hashtag in your account on Bluesky. Viral. Here's the Edusky feed.

Helen J. DeWaard, Canadian Journal of Learning Technology, Nov 13, 2024

I enjoyed the lavish illustrations in this article, a rarity in academic publications. After anm introductory section, the paper offers what is essentially a dialogue around the topic of sharing and openness in education. This bit from  the abstract resonated most with me: "It is becoming ever more important to share expertise as practitioners, researchers, and theorists in the field of education by making explicit what is often tacit and unspoken, and when sharing knowledge, reflections, and actions. By actively thinking-out-loud through blogs, social media, and open scholarly publications, educators can openly share details of what, how, and why they do what they do." This is the space where OLDaily operates - a somewhat middle ground between full academia on the one hand and the popular press on the other.

Paula MacDowell, Kristin Moskalyk, Katrina Korchinski, Dirk Morrison, Canadian Journal of Learning and Technology, Nov 13, 2024

This paper reports on a process where thirty-five teachers enrolled in an elective three-credit multimedia design course "engaged in experiential activities focussed on developing artificial intelligence (AI) literacy, alongside a collaborative assignment to co-author an open-access textbook, Teaching and Creating With Generative Artificial Intelligence." In the process, "the Student Artificial Intelligence Literacy (SAIL) framework was developed (illustrated)." The paper concludes with the usual recommendations ('do no harm', 'develop communication skills', etc.). Each participant wrote a chapter, though a common template was used. I very much like the idea of producing a useful open resource as part of class activities. Oddly, the article doesn't provide a link to the textbook, but I found it here. It's a nice selection of 'how-to' articles that readers, I think, will find useful. One chapter (chapter 20 1/2?) is missing.
