From its inception, The Internet has seen a remarkable evolution in how we manage our online personas. In the era of dial-up modems and ASCII art, digital identity was often nothing more than a simple pseudonym on a bulletin board system (BBS). Fast forward to today, in the year we celebrate the 30th anniversary of the release of the World Wide Web source code, the landscape has dramatically changed. We've transitioned from those rudimentary beginnings to the sophisticated realm of Web3 and decentralized identities, offering a more secure and personalized digital experience. The concept of online privacy, once in its infancy, has now become a focal point in the conversation about digital identity. 

Following the era of bulletin board systems, the advent of email and social media platforms marked a significant shift in how we interact online. Email addresses quickly became the universal key to unlocking various internet services, from online shopping to digital subscriptions. Then came the rise of social media platforms like Friendster, MySpace, and eventually, Facebook. These platforms not only served as social networking sites but also became de facto identity providers. Your profile was no longer just a social page; it was your digital passport to an expanding online universe. As we moved into this new phase, two names emerged as the gatekeepers of our online identities: Google and Facebook. Their influence has been so pervasive that they've become synonymous with digital identity itself, setting the stage for a conversation on the power dynamics and privacy implications involved. 

Building on their pervasive influence, Google and Facebook began to offer streamlined experiences that extended far beyond their own platforms. With just a single login, you could access a myriad of third-party services, effectively making these tech giants the universal key to the internet. This consolidation of digital identity into the hands of a few has had far-reaching implications, not just for user convenience but also for how we manage and protect our personal data online. It's this very convenience that paved the way for technologies like OAuth to become integral in our digital lives. 

The introduction of OAuth technology was a watershed moment in the realm of digital identity. Acting as a digital handshake between platforms, OAuth allowed users to grant permission to third-party services to access specific types of data, all without sharing their login credentials. While this brought unparalleled ease to the user experience, it also sparked a new set of questions around data privacy and control. OAuth became the double-edged sword of digital identity: simplifying user access while also centralizing data in a way that made many question who truly owns their online persona. 

While OAuth and centralized platforms like Google and Facebook have made strides in simplifying digital identity, they've also raised valid concerns about data ownership and privacy. This has led to a growing interest in alternative, decentralized identity solutions that put control back into the hands of the individual. Enter the world of onchain identities—innovative systems like Decentralized Identifiers (DID), Ethereum Name Service (ENS), and even unique NFTs are redefining what digital identity can be in the era of Web3. 

The World Wide Web Consortium (W3C) and the Decentralized Identity Foundation (DIF) are leading the charge in setting standards for decentralized identities. While W3C focuses on creating universal standards for the Web, DIF aims to build an ecosystem where decentralized identities can thrive. Ethereum, a blockchain platform, serves as a practical example where these standards are being implemented, offering a decentralized network that supports a wide range of identity solutions. 

Currently, traditional concepts like DNS and name space are being reimagined. The Ethereum Name Service (ENS) serves as a foundational example of how traditional DNS and name space concepts are evolving in the decentralized identity landscape. ENS simplifies complex Ethereum addresses into human-readable names, making it easier to interact with decentralized applications (dApps) and smart contracts. More importantly, ENS allows you to associate various types of information with your name, such as your Twitter handle or email, all verified onchain. This not only puts you in control of your digital identity but also enhances interoperability across different decentralized platforms. 

Building on the idea of identifiers like ENS names, it's crucial to differentiate between what serves as an identifier and what constitutes a comprehensive identity. An ENS name, while useful for basic interactions, doesn't fully encapsulate an individual's attributes, experiences, and credentials. In contrast, a decentralized identity is a complex, evolving construct that can be verified onchain, offering a nuanced way to establish trust. However, this complexity comes with its own set of challenges, such as the potential privacy risks of putting sensitive information on a public blockchain, a concern highlighted by @nembal on Twitter. 

In a similar vein, digital assets like CryptoPunks and Doodles are redefining what identifiers can be in the decentralized world. These unique NFTs serve as more than just digital art; they can be used as Profile Pictures (PFPs) that become part of your digital identity. Just as owning a specific ENS name can signal your affiliations or interests, owning a particular NFT can make a statement about your personality, interests, or the communities you are part of. 

This trend extends beyond mere aesthetics. Just as people change their traditional PFPs to reflect social causes they support, owning a specific NFT can signal your affiliation with certain communities or causes. On platforms like Discord, using an NFT as your PFP can also serve a functional purpose, helping to verify your identity and maintain the integrity of the community. This opens up a new dimension in how we think about digital identity, adding layers of complexity and meaning that go beyond what centralized systems can offer. It raises interesting questions about the role of digital assets in establishing identity, community integrity, and even ethical considerations around supporting social movements. 

Expanding on decentralized identifiers and their role in the ecosystem, we also see a reimagining of traditional credentials and reputation. Unlike centralized systems where credentials are often issued by a single authority, decentralized models allow for a more dynamic and community-driven approach to establishing trust. For example, non-transferable tokens, similar to the "soulbound tokens" discussed by E. Glen Weyl, Puja Ohlhaver, and Vitalik Buterin, can represent various forms of commitments, affiliations, and even reputation. These tokens can be issued by individuals or organizations within a network, offering a flexible way to attest to one's social and professional standing. This shift not only allows for a more comprehensive and self-sovereign digital identity but also opens up new avenues for financial and social interactions that are based on a more nuanced understanding of trust and reputation. 

The foundation of decentralized credentials and reputations lies in onchain data, which is stored on a public ledger. This transparent storage ensures that all transactions and interactions are visible to anyone, providing a democratizing feature that allows for community-based scrutiny and verification. This level of transparency not only establishes trust but also serves as a reliable record of onchain activity. While it's often said that blockchain records are immutable, it's more accurate to describe them as highly tamper-resistant. Once data is added, altering it becomes both computationally expensive and practically improbable, making this record a trustworthy source for verifying credentials and transactions. 

In a digital environment saturated with information, the verified and tamper-resistant nature of onchain data acts as a "signal in the noise." It helps to filter out irrelevant or misleading information, thereby aiding in the establishment of an individual's or entity's reputation within a decentralized network. Beyond serving as a reliable record, onchain data can also be modeled to generate actionable insights. Advanced analytics and algorithms can sift through this data to identify patterns or trends, which can then inform decisions about an individual's reputation or identity. This offers a level of personalization and security that is often unattainable in centralized systems. 

The richness and reliability of onchain data pave the way for more advanced features in digital identity, such as composability and interoperability. In this context, composability refers to the ability to build identities that comprise various aspects of user activity. For example, one's decentralized identity could be a composite of different elements like an Ethereum Name Service (ENS) name, Decentralized Identifiers (DIDs), unique NFTs, profile pictures, soulbound tokens (SBTs), and even social media handles like Twitter. Each of these elements can be verified onchain, adding layers of complexity and nuance to how we understand and interact with digital identities. 

Interoperability, on the other hand, ensures that these composite identities are not siloed within one platform or network. Instead, they can be portable across different decentralized platforms, enhancing the user experience and broadening the scope of interactions. This portability is crucial for the adoption and scalability of decentralized identity systems, as it allows individuals to carry their reputations, credentials, and social proofs across various communities and networks. 

The notions of composability and interoperability naturally lead us to the concept of "Identity Legos." Just as traditional Lego blocks can be assembled in countless ways to create various structures, Identity Legos allow for the modular construction of digital identities using different components. These could range from Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to unique NFTs that exist across multiple blockchains. Soulbound tokens (SBTs) can also be integrated into this framework, serving as non-transferable tokens that represent various forms of commitments, affiliations, and reputations. 

Innovative protocols are emerging to facilitate these combinations. For instance, Orange Protocol allows for the linking of DIDs to SBTs, enabling a more nuanced representation of identity that can include both static identifiers and dynamic, community-verified attributes. This modular approach not only enriches the concept of digital identity but also offers unprecedented flexibility. It allows individuals to tailor their identities according to different contexts, carrying their reputations, credentials, and social proofs seamlessly across various platforms and communities. 

The modular approach of Identity Legos has not only enriched our understanding of what digital identity can be but also paved the way for practical, real-world applications. As we navigate this evolving landscape, a handful of trailblazing companies stand out for their contributions to the field. These include ENS, Ontology, Disco, Worldcoin, Gitcoin Passport, and Orange Protocol. Each is playing a pivotal role in shaping the future of decentralized identity, and in the sections that follow, we'll delve into the unique approaches and innovations each is bringing to the table.
