Web3 & decentralized identities have been around for a few years - early projects date back to 2015 - revolutionizing our online identity: an aspect of our digital lives we couldn’t control before now. In 2023, the spotlight shone brightly on DIDs with the launch of Sam Altman’s pet project, Worldcoin, sparking a renewed interest in DID projects. DIDs, with their focus on decentralization and self-sovereignty, are stored on the blockchain, providing users with a level of security and transparency that was previously unattainable. This singular advantage - amongst many - is gradually making DIDs a go-to solution to mitigating and preventing data breaches, identity theft, and privacy violations, which are concerns associated with traditional identity systems.
Traditional Challenges & The Promise of Decentralized Identity
Traditional identity management systems are centralized, posing significant challenges. A primary issue is the vulnerability to data breaches by cybercriminals; when systems are compromised, sensitive personal information is exposed. This exposure causes financial losses and loss of trust in the institutions by the millions entrusting this data. But it's not just data breaches that are a concern. Other vulnerabilities include the potential for identity theft, the misuse of personal data for targeted advertising, and the lack of control individuals have over their information. This dilemma depicts another drawback of traditional identity systems: individuals need more control over their data, whether it is about storage or how it is used and shared. Because of the oversight, companies often monetize the data they store without explicit consent from their owners. Users are not blind or oblivious, as they have raised ethical concerns while their mistrust grows. Furthermore, users must worry about getting their identity stolen by a hacker and being impersonated for fraudulent activities. Now add the trauma of impersonation with the long, difficult process of recovering from identity theft, plus the financial strain and we have a scarred individual.
One of the most notorious examples is the 2017 Equifax incident, where the personal information –Social Security numbers, birth dates, and addresses– of about 147 Americans, along with 15.2 million British citizens and about 19,000 Canadian citizens, were exposed, making it one of the largest identity theft crimes. Another infamous incident is the Facebook-Cambridge Analytica scandal, where millions of Facebook users' data was harvested and used for political advertising without their consent. So you see, it doesn't matter whether it's an individual or an institution; traditional identity management is inadequate.
Blockchain solutions offer much-needed relief to users at the mercy of centralized entities, empowering them to control and verify their identity without exposing sensitive information to third parties. This shift in power serves as a cornerstone of privacy and trust in the Web3 ecosystem, significantly reducing the vulnerability and unease that traditional systems often bring.
DIDs and Their Relation to Blockchain
DIDs serve as unique and tamper-proof identifiers, making them ideal for application in identity management. There are multiple categories related to DIDs, and here they are:
Decentralized identity solutions, a category that empowers users with control over their digital identities, are built on the fundamental components of decentralization.
Self-Sovereign Identity (SSI): SSIs are closely tied to DIDs, as their frameworks rely on DIDs. With an SSI, users can authenticate themselves and share their credentials selectively, ensuring their personal data is secure and under their control.
Verifiable Credentials: This category involves using DIDs to issue and verify digital statements about a subject. These verifiable credentials can be used to prove things about a person or an organization, such as age, qualifications, or membership in a group.
The relationship between DIDs and blockchain technology is fundamental. DIDs incorporate privacy-preserving features while enjoying the robustness and security of the network in which they are generated.
Notable DID Projects
The growth of DIDs has been rapid in recent years with multiple projects entering the ecosystem and the existing ones solidifying their presence by adapting and transitioning. So, as the world anticipates the holistic shift to Web3, which DID projects are taking charge and onboarding users with unique decentralized identity management? Let’s compare the builders pioneering DID technology.
Ethereum Name Service (ENS)
ENS provides human-readable names for blockchain addresses, i.e. replacing the hexadecimal address with a familiar name like “Bob.eth.” In February 2024, GoDaddy Inc. partnered with ENS to connect user’s names to their web domains. In April 2024, ENS also integrated .box domain names which is the first on-chain TLD (Top Level Domain) included in the ENS manager app alongside the .eth TLD. As of March 2024, Google has integrated ENS data into its search results, meaning you can search for .eth names and view on-chain information.

Challenges of DID Projects
Interoperability
A significant challenge DID projects must overcome is interoperability. Identity solutions will one day be a dime a dozen, proliferated like the chains they're built on. It's one thing to have a plethora of DID businesses; it's another to make them work together. Without interoperability, users are limited to specific ecosystems. Therein lies the problem.
Regulations & Compliance
The regulatory landscape is complex. Navigating it is another critical hurdle DID projects face because while they offer numerous benefits, they must comply with existing data protection laws (e.g., FINRA, FedRamp, HIPAA, GDPR). So, it is paramount to balance everything.
Scalability
As with many blockchain-based solutions, scalability is a concern. This is linked to user adoption; to accommodate the needs of numerous users, DID systems must be able to handle large interactions while compromising neither performance nor user experience. This is a pressing need as more users are onboarded to DIDs.
Adoption
For DID solutions to succeed, widespread adoption must come first. This will be done by overcoming the inertia of established systems and convincing users to switch to DIDs, which is a challenging feat.
Technicalities
Are DIDs easy to build? Do existing projects release code and SDKs to facilitate building on and integrating their protocols? Complexity slows development and makes adoption cumbersome, especially for those less familiar with the technology. Builders should ensure their platforms work together.
