The rise of Web2 has transformed the way we interact with the Internet, facilitating global communication, access to information, and the emergence of innovative online services. However, this era of the internet is not without its drawbacks, raising concerns about data privacy, user control, and centralized control over online platforms.

In response to these challenges, Web5 emerges as a paradigm shift, envisioning a decentralized internet that empowers individuals and organizations to regain control over their data, digital identity, and online experiences.

At the forefront of this movement is TBD, a division of Block (formerly Square). TBD is dedicated to building a decentralized web infrastructure, tagged 'Web5', without the complexities of Web3 technologies (read: blockchain).

TBD's open-source SDK provides developers with the tools and components necessary to create decentralized web applications (DWAs). DWAs operate on a distributed network of nodes, eliminating the need for centralized servers and empowering users with greater control over their data. They offer decentralized identity and data storage capabilities.

To delve into the world of decentralized web apps and explore the capabilities of the Web5 SDK, let's first embark on a journey through the key concepts and functionalities of this groundbreaking technology.

Web5: What It Is and Why You Should Care

The current Internet is predominantly centralized with several shortcomings, and power and control are concentrated in the hands of a few large corporations. In contrast, Web5 envisions a more equitable and user-centric Internet where individuals have ownership and control over their data and identity.

Here is a brief explanation of the core concepts of Web5, such as decentralization, self-sovereignty, and open protocols:

Decentralization

Decentralization is one of the key principles of Web5. This means that no single entity controls the web but instead, it is spread out across a network of computers. This makes it more resilient and resistant to censorship.

Self-sovereignty

Self-sovereignty means that individuals and organizations have control over their data. This is in contrast to Web2, where data is often controlled by large corporations. In Web5, individuals can choose how and with whom they share their data.

Open Protocols

Open protocols are open standards that anyone can use to build applications. This means that no one company controls the web. This makes the web more competitive, leaving room for the ecosystem to evolve and foster innovation.

These three concepts are just the beginning of the Web5 revolution. There are many other important concepts that are still being developed. However, these three form the foundation of a more decentralized, secure, and democratized Internet.

The open-source Web5 toolkit plays a crucial role in realizing this vision through a set of tools and libraries that enable developers to build decentralized applications that run on a decentralized network, eliminating the need for intermediaries and centralized platforms.

Benefits and Potential Use Cases of Web5

Some benefits of Web5 include:

• More privacy and security: Since your data is not controlled by any central authority, it is more secure and private.

• More control over your data: You can choose how and with whom you share your data.

• More open and competitive: The web is not controlled by any one company but rather relies on open-source technologies, so it is more open and competitive.

TBD's Web5 SDK empowers developers to create a wide range of DWAs across various sectors. Some real-world Web5 use cases include:

• Decentralized social networks: Reimagine social media platforms with SSIs and decentralized data ownership. These social networks are not controlled by any one company, so they are more resistant to censorship. For the DSA folks, a true graph😎.

• Decentralized exchanges: TBD has a decentralized, permissionless protocol (tbDEX) which introduces a trustless payment system for bridging legacy money with digital assets. Free, fast financial access for all💸.

• Decentralized web applications (DWAs): DWAs are applications that are built on top of distributed technologies. They are often more secure and privacy-preserving than traditional centralized applications🔐.

• E-commerce platforms: Leverage Web5 and SSIs to build secure and transparent peer-to-peer marketplaces that empower buyers and sellers to manage their transactions without intermediaries.

• Secure messaging applications: Imagine Signal but with better control over all your data🛡️. Enhance communication privacy and data ownership with decentralized messaging platforms that resist censorship and data breaches.

• Data storage solutions: Provide decentralized data storage services that offer enhanced security, privacy, and control over sensitive data.

Decentralized Identifiers (DIDs) and Self-sovereign Identity

Self-sovereign identity (SSI) is a fundamental principle of Web5. It empowers individuals to manage their identities and data without relying on third-party authorities. Decentralized identifiers (DIDs) are the building blocks of self-sovereign digital identity.

DIDs are unique digital identifiers that individuals and organizations can create and control, similar to email addresses or usernames. Unlike the former, however, individuals have complete control over their identity data and can choose how and with whom to share it.

TBD's SDK provides comprehensive support for DIDs, enabling developers to create, manage, and utilize DIDs within their DWAs. Developers can use these tools to integrate DIDs into their DWAs, enabling users to securely manage their identities and control access to their data.

This empowers users to securely manage/establish their digital identities, control access to their data, and engage in trustless interactions without relying on centralized authorities.

Verified Credentials (VCs) and Verifiable Claims

Verified credentials (VCs) are tamper-proof digital certificates that contain verifiable claims about an individual, organization, or entity. These claims can range from personally identifiable information like name, age, and location to more complex credentials like educational qualifications or professional licenses.

Trusted entities issue VCs which can be used to prove various attributes, such as education, employment, or qualifications. Imagine a future where more sensitive information like your credit score, social security number (SSN), and social media account data sits pretty on a decentralized data store based on DWNs.

TBD's toolkit facilitates the issuance, exchange, and verification of VCs, enabling secure and verifiable data sharing between individuals, organizations, and DWAs. Developers can use these tools to integrate VCs into their DWAs, empowering users to prove their credentials and establish trust in the decentralized web.

Decentralized Data Storage through DWNs

Decentralized web nodes (DWNs) are the backbone of Web5's decentralized data storage. DWNs are distributed servers that store and manage data in a decentralized manner, ensuring that data is not controlled by any single entity.

Unlike traditional cloud storage, DWNs eliminate centralized data storage, preventing single points of failure and enhancing data privacy. With DWNs, you call the shots, literally. You can decide and manage who gains access to your data.

TBD's toolkit provides tools for seamlessly interacting with DWNs. Developers can use these tools to store and retrieve data in a decentralized manner, ensuring data privacy, security, and resilience.

Building Decentralized Applications with TBD's Toolkit

TBD's toolkit offers a comprehensive set of tools for building DWAs. The toolkit includes libraries for DID management, VC issuance and verification, decentralized data storage, and secure communication protocols.

Developers can use the toolkit to build a wide range of DWAs, including social networks, marketplaces, and decentralized financial (DeFi) solutions. The toolkit's modular design allows developers to select the components they need to build their specific DWAs. Plug and play, it's really that simple🎮.

In this series, we'll look into building real-world applications with the open-source Web5 SDK.

In the next part, we'll see how various components of the Web5 SDK work in tandem to enable developers to create DWAs with self-sovereign identity (SSI) management and decentralized data storage capabilities.

We'll also build a simple application to showcase the potential of Web5 technologies and how developers can leverage it to build decentralized, user-centric web applications with a more positive UX in comparison to Web3 dApps. We'll cap it off with a real-world project with a practical use case.

Future of TBD's Toolkit and the Decentralized Web

The Web5 project, alongside its open-source SDK, is poised to transform the internet landscape by empowering individuals and organizations to reclaim control over their data, identity, and online experiences.

With its commitment to self-sovereignty and decentralization through open protocols, TBD is paving the way for a decentralized future where you truly own and control your identity data — au revoir to gatekeeping and censorship by centralized corporations.

As the decentralized web continues to evolve, the Web5 toolkit is expected to play a central role in enabling developers to create secure, user-focused DWAs that redefine how we interact with the internet. However, challenges remain in the development of the decentralized web. Interoperability between decentralized networks and protocols is crucial for the widespread adoption of Web5.

Additionally, education and awareness about decentralized technologies are essential to empower individuals to take ownership and control of their data and identity.

Despite these challenges, the vision of a decentralized web offers a promising future for a more equitable and resilient internet focused on data integrity. Web5 will no doubt become a valuable tool in realizing this vision, empowering developers to build the next generation of decentralized applications.
