W3C For immediate release

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

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



https://www.w3.org/ — 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:

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.

ConsenSys

"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."

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

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."
