Decentralized Identifiers (DIDs) v1.0 becomes a W3C Recommendation

Author(s) and publish date


A new tool to empower everyone on the web with privacy-respecting online identity and consent-based data sharing

Read testimonials from W3C Members and the industry — 19 July 2022 — The World Wide Web Consortium (W3C) has announced that Decentralized Identifiers (DIDs) v1.0 is now an official Web standard. This new type of verifiable identifier, which does not require a centralized registry, will enable both individuals and organizations to take greater control of their online information and relationships while also providing greater security and privacy.

There is a historical analog to this announcement in the evolution of mobile phone numbers. Originally these were owned by the mobile carrier and "rented" to the individual. This required individuals to change numbers if they changed carriers. With the adoption of mobile phone number portability, individuals could now "take their numbers with them" when switching carriers.

The same is true of most email addresses and social network addresses today—they are not “owned” by individuals and must be changed if the individual changes providers. By contrast, W3C Decentralized Identifiers can be controlled by the individuals or organizations that create them, are portable between service providers, and can last for as long as their controller wants to continue using them.

Whatsmore, DIDs have the unique property of enabling the controller to verify ownership of the DID using cryptography. This can enable any controller of a DID—an individual, an organization, an online community, a government, an IoT device—to engage in more trustworthy transactions online. For individuals in particular, DIDs can put them back in control of their personal data and consent, and also enable more respectful bi-directional trust relationships where forgery is prevented, privacy is honored, and usability is enhanced.

Fundamentally, Decentralized Identifiers are a new type of globally unambiguous identifier that can be used to identify any subject (e.g., a person, an organization, a device, a product, a location, even an abstract entity or a concept). Each DID resolves to a DID document that contains the cryptographic material and other metadata for controlling the DID. The foundational pillars of the DID specification are: 1) DIDs do not require a central issuing agency (decentralized), 2) DIDs do not require the continued operation of an underlying organization (persistent), 3) Control of DIDs, and the information they are associated with, can be proven cryptographically (verifiable), and 4) DID metadata can be discovered (resolvable).

Markets adopting DIDs

W3C Decentralized Identifiers, coupled with W3C Verifiable Credentials, are being used across a number of markets where identification and data authenticity is a concern:

  • Governments – The US, Canada, and the EU, are exploring the use of DIDs to provide privacy-protecting digital identity documentation for their businesses and residents, which enable those entities to choose how and when their data is shared.
  • Retailers – convenience stores, grocery stores, restaurants, bars, and consumer goods companies in the US are utilizing DIDs for new digital age verification programs to increase privacy, checkout speed, and combat the use of fraudulent identity documents when purchasing age-gated products.
  • Supply chain stakeholders — global government regulators, trade standards institutions, vendors, shippers, and retailers—are using DIDs to explore next generation systems that more accurately verify the origin and destination of products and services, which will streamline and enable the reporting designed to apply correct tariffs, prevent dumping, and monitor transshipment.
  • Workforce – universities, job training programs, and education standards organizations are adopting DIDs in order to issue digital learning credentials that are controlled and shared by the graduate when applying for higher education or workforce positions.

The Work Continues at W3C

W3C, composed of over 450 organizations, has made the investment in W3C Decentralized Identifiers and W3C Verifiable Credentials to ensure a more decentralized, privacy-respecting, and consent-based data sharing ecosystem. Official standards work will continue on these technologies through the newly re-chartered W3C Verifiable Credentials 2.0 Working Group, which will focus on expanding functionality based on market feedback. Further incubation on future privacy-respecting technologies will occur through the W3C Credentials Community Group, which is open to participation by the general public.

"W3C Decentralized identifiers represent a huge step forward in being able to create privacy preserving systems. Coupled with W3C Verifiable Credentials, Decentralized Identifiers have enabled design and standardization of an Age Verification system that meets regulatory requirements while protecting private information. Creating systems that can do both things has formerly been a challenging task, made easier with Decentralized Identifiers and Verifiable Credentials. Conexxus is a long term W3C member, and is the standards body for the convenience retail sector representing 152,000 retail outlets. W3C Decentralized Identifiers have helped create an important privacy preserving standard for the TruAge program."

Gray Taylor, Executive Director, Conexxus


"ConsenSys are pleased that W3C has endorsed the DID 1.0 specification as a W3C Recommendation. This is an important step toward empowering individuals to control their own identity and how it is used. 

The DID framework enables an interoperable approach to identity that can be based on different platforms, providing cross-network interoperability. We value this approach, and the ability of W3C to produce such standards to underpin the highly hetergeneous web of today, and of the future. 

At ConsenSys we have been working half a decade with this approach in the Ethereum technology stack. This can provide an ideal basis for the implementation of secure and scalable DID methods, that frees the world from relying only on very large scale providers to manage people's identity. 

We look forward to this work, along with Verifiable Credentials and other connected standards, forming an underpinning for the new future we are building where decentralised identity management and reputation systems give people more control of their online identity."

Charles "chaals" Nevile, Lead Standards Architect, ConsenSys

Danube Tech

"Like many other companies, we welcome the decision to advance DID Core 1.0 to W3C Recommendation. For Danube Tech, DIDs are more than just a technical building block and a prerequisite for other functionality such as Verifiable Credentials or DID-based authentication. For us, DIDs are a symbol of empowerment and independence. They lie at the heart of a vision that relates physical to digital identities, in a way where human rights and democratic principles are "built-into" the technical architectures.

Digital Bazaar

"Our work with various governments, education institutions, banks, supply chain, and the retail sector utilize W3C Decentralized Identifiers and W3C Verifiable Credentials to build next generation privacy-enhancing digital credential issuance, verification, and encrypted storage services. All of our products support W3C Verifiable Credentials and W3C Decentralized Identifiers and help reassure our customers that they are investing in a broad, competitive ecosystem of software vendors that all support these interoperable Web standards. 

From an individual's perspective, DIDs enable a simpler, safer way to store, share, update, and verify personal data using privacy-respecting identifiers under their personal control. From an enterprise perspective, decentralized technology has the potential to reverse the trends of data breaches and data theft. Companies will no longer need to spend a fortune in the expensive collection–and protection–of data that can quickly become out-of-date, incomplete, or inaccurate. Furthermore, organizations can know with greater certainty that they are interacting with an individual that has the right to use the data they are sharing rather than receiving it from a thief or illicit data broker. 

We applaud the newest global standard at the World Wide Web Consortium and look forward to new work at W3C that will enhance and further standardize consent-based data sharing standards that respect individual right to privacy."

Manu Sporny, CEO, Digital Bazaar

"Intel Corporation congratulates the DID Working Group on Decentralized Identifier (DID) 1.0 reaching W3C Recommendation status. 

DID provides a framework to unify and consolidate multiple evolving identity systems. Consolidating identity systems within a single framework is useful for validating the authenticity of information and preserving its integrity as it is moved and processed among cloud, edge, and client systems. This potentially increases the capabilities of the Web to connect and unify multiple sources of information. 

The continuing evolution of this work will be key to the development of new technologies in the fields of supply chain management and Internet of Things (IoT) devices and services. For example, a Birds of a Feather (BOF) discussion group at IETF Supply Chain Integrity, Transparency, and Trust (SCITT) has already highlighted DID as a useful approach in providing much needed structure for exchanging information through the supply chain, and the Web of Things (WoT) WG is planning to support DID for identifying and discovering IoT devices and metadata. 

Intel Corporation supports this work and encourages the DID Working Group to continue working towards the convergence of widely implemented and adopted standardized best practices for identity in its next charter."

The DCC approach focuses on open standards, open processes, and developing open source software to ensure learner agency in the use of their digital credentials. One of the key components of these approaches is using the W3C Decentralized Identifiers (DIDs) specification so that learners and issuers can securely associate themselves with their credentials. The DCC has chosen to implement DIDs along with W3C Verifiable Credentials to enable an interoperable, verifiable, and more trustworthy exchange of digital academic credentials."

Brandon Muramatsu, Associate Director, Projects, MIT Open Learning

Ology Newswire, Inc.

"Decentralized Identifiers are an important tool to level the playing field. With DIDs, individuals and small teams enjoy the same level of cryptographic verification of identity, claims, and content that is available to the largest and most powerful governments and corporations. 

At Ology Newswire, DIDs enable digital publishers to contribute content to the public square with cryptographic provenance to enhance censorship resistance. A free WordPress plugin serves DIDs for each author on a WordPress site giving the publisher direct control over verification. 

The DID standard is flexible enough to empower not just major corporations and governments, but also individual people and small groups with something important to say or a small enterprise to build. The wide range of applicability embodies the heart and soul of open internet standards."

Christian Gribneau, CEO, Ology Newswire, Inc.

PassiveBolt Inc

"PassiveBolt is thrilled that W3C has endorsed the Decentralized Identity specification DID 1.0. As the first company developing Web 3 based physical access control solutions, we are applying decentralized identity to address problems in the security industry. Issuing credentials for people to access secure spaces currently requires property managers to centrally store PII which exposes them to security risks, regulatory risks, and high costs. PassiveBolt is pioneering a Web3 platform that eliminates regulatory and security risks by enabling property managers to provide access to their secure spaces via user-owned and controlled digital identities based on DIDs."

Kabir Maiga, CEO, PassiveBolt

Spruce Systems, Inc.

Identity Woman in Business

"I still remember that first whiteboard session for what would become Decentralized Identifiers (DID) v1.0 that I helped facilitate following the ID2020 conference in 2016. Since then, as a community steward and contributor, I have had the pleasure to watch the DID specification progress through workshoping at the Internet Identity Workshop and pre-standardization in the Credentials Community Group before spec work graduated into an official W3C working group - which I participated in as well. It is a big milestone for the community and towards the infrastructure we need to support individuals really owning and controlling the digital representations of themselves. In my new role as a Principal of a Decentralized Identity consulting firm, I look forward to helping organizations understand and implement this standard."

Kaliya Young, Identity Woman, Founder and Principal at Identity Woman in Business, W3C Invited Expert, co-founder of the Internet Identity Workshop

"Decentralised Identifiers open a new world for individuals to share personal data (credentials) while protecting their privacy. One fundamental aspect of any data exchange is auditability and regulatory compliance. Through our work with NGI-Trust eSSIF-Lab, MyData and similar organisations, has contributed to defining and standardising data exchange agreements (did:mydata) that make every personal data transaction immutable, trustworthy and auditable. This will create new opportunities with seamless data sharing across public and private entities governed by new data regulations."

The National Association of Convenience Stores

"In the Convenience Retail channel, age restricted items represent roughly 50 million transactions a day! Restricted items traditionally have been limited within a single transaction, with the age checked using a driver’s license. Regulatory scrutiny now extends to industry-wide sales of items to individuals no matter where they purchase them, and verifying age for the sale of those items using a driver's license presents a big privacy threat. Addressing this issue, NACS has created the TruAge program using W3C Decentralized Identifiers and Verifiable Credentials. Working with our partner Conexxus, NACS has been able to provide a system using open standards that gives a clear “on ramp” for additional participants in the ecosystem. TruAge supports both in-store and on-line transactions, providing safe and responsible sales of age restricted goods while preserving consumer privacy.

NACS advances the role of convenience stores as positive economic, social and philanthropic contributors to the communities they serve. The U.S. convenience store industry, with more than 152,000 stores nationwide selling fuel, food and merchandise, serves 165 million customers daily—half of the U.S. population—and has sales that are 11% of total U.S. retail and foodservice sales. NACS has 1,900 retailers and 1,800 supplier members from more than 50 countries."
