With the advent of blockchain and smart contracts came a vision for the decentralized internet. Rebuilding important internet infrastructure in a trustless way is a key component of Web3. But, in addition to infrastructure, data and identity ownership is critical. This brings decentralized identity to the forefront.

Giving users complete ownership over their data and online identities is a core principle of Web3. Decentralized identity allows individuals to eliminate trust in big tech and other centralized companies who sell, exploit, or lose user data. Let’s discuss what decentralized identity on Bitcoin looks like.

What is Decentralized Identity?

Decentralized Identity (DID) is a concept that springs from the philosophy of decentralization that started the crypto movement. The goal of DID is to empower users with control over their personal information in a secure and private manner. Unlike traditional identity systems where a central authority holds and verifies user information, DIDs operate on the principles of trustlessness and individual sovereignty.

In the growing Web3 world, DIDs are unique identifiers tied to individuals. These identifiers are created and managed on decentralized networks like Bitcoin. DIDs let users have complete control of access to their personal data without relying on intermediaries.

Decentralized identity also allows users to have universal credentials. Instead of creating a user account for social media, your email, and your utilities online, DID would allow you to have a single, universal login.

Think of DID like a digital passport. But instead of being issued and controlled by a government, it's generated on a decentralized, immutable network. Each user has a unique, cryptographic identifier that they own and control. This identifier, or DID, becomes the cornerstone of their digital identity. It enables interactions in the decentralized ecosystem without sacrificing privacy or security.

Web3 can also open a world of seamless and trustless transactions, allowing users to prove their identity without revealing unnecessary details. This paradigm shift towards decentralized identity aligns with the core tenets of the blockchain movement. 

Is There Decentralized Identity on Bitcoin?

In keeping with a cypherpunk ethos of decentralization and individual ownership, decentralized identity has been growing on Bitcoin for years. The concept began in the early days of blockchain and, since then, technologies and implementations have only improved.

One great example of DID on Bitcoin is Bitcoin Name System. BNS is a system specifically designed for Bitcoin, connecting Stacks usernames to off-chain states. Stacks acts as a layer on top of Bitcoin (an L2), allowing easy implementation of decentralized identity features. Unlike traditional naming systems like DNS, BNS operates without relying on central points of control.

For web3 to fulfill its goal, decentralized identity is pivotal. Truly giving users control of their money and information requires secure and sovereign identity. BNS plays a crucial role in making this reality. It provides a secure and decentralized way for users to associate their identity with their Bitcoin transactions. 

Benefits of BNS

There are many benefits to implementing decentralized identity on Bitcoin. Here are a few:

  • Global Uniqueness: BNS ensures that names are globally unique, eliminating the possibility of duplicates, giving a distinct identity to every user

  • Human-Meaningful Names: BNS allows users to choose names that are readable and meaningful. There is no need for a long series of numbers and letters.

  • Strong Ownership: Ownership is tied to ECDSA private keys, ensuring that only the owner has the authority to change the state associated with their name.

  • Integration with Wallets: BNS seamlessly integrates with Bitcoin wallets like Leather, offering users the ability to use their BNS names for transactions. 

  • Enhanced User Experience: The use of BNS names in transactions streamlines the process, making it more intuitive and user-friendly.

  • Potential for Various Applications: BNS opens the door to building diverse network applications, including domain name services resistant to hijacking, social media platforms with heightened security, and much more.

  • Alignment with Web3 Goals: DID on Bitcoin aligns with the principles of Web3, offering a secure and decentralized way for users to own their identities 

BNS brings a new layer of identity management to Bitcoin, aligning with the principles of decentralization and user ownership in the Web3 era.

How Do Bitcoin Wallets Use BNS?

Several Bitcoin wallets have already integrated BNS, recognizing its potential to improve user identity and streamline transactions. Leather wallet, for instance, provides easy usability for BNS names directly within the wallet interface. This integration is helping move the ecosystem towards more user-centric identity management.

With BNS integration, users can quickly conduct transactions using their unique BNS names. This provides individuals with a distinct and personal identity on the Bitcoin network, tied to their BNS names. Instead of having to copy and paste a long, cryptographic address for a wallet, users can simply use a BNS domain.

This not only enhances the user experience but also reduces the likelihood of errors in the transaction process. BNS facilitates a more human-centric approach to transactions on the Bitcoin network.


In an era when users are becoming more aware of how their data is constantly compromised online, DID is becoming more and more important. By providing users with unique, globally recognizable identities, Bitcoin DID empowers individuals to navigate the online world with autonomy and security.

The integration of BNS into Bitcoin wallets like Leather, signals a shift towards a more user-friendly crypto world. The ease of using DID for transactions not only simplifies the process but also enhances overall user experience. In this evolving landscape, embracing technologies that prioritize individual ownership of identity becomes not just a choice but a necessity.

If you want to foray into the world of decentralized identity on Bitcoin, Leather wallet and systems like BNS are the perfect place to start. In 2024 and beyond, it’s more important than ever to take control of your online data.
