In today’s digital age, the protection of our individual identities has become increasingly crucial. As technology advances and we rely more on digital platforms, it has become alarmingly easy for others to gain access to, control, and manipulate the information that comprises our identities. This pervasive issue has raised global concerns and has persisted for years without significant resolution.
Despite the extensive media coverage and documentaries highlighting identity manipulation, the impact of these revelations has been disappointingly minimal. However, this state of affairs is not set to continue for long.
Undoubtedly, Blockchain technology is changing the narrative across different walks of life through innovations and technological advancement, and one of the most remarkable innovations currently making waves is Decentralized Identifiers(DID). From social identity down to official credentials, DID is changing the status quo and completely rewriting the narrative through self-sovereign identity, thereby putting people in control of their data and identity.
DIDs are also a central part of the cosmos ecosystem as they offer privacy, security, and interoperable identity that you can carry across different networks in the ecosystem.
Throughout this article, we will help you understand what DIDs are and their benefit on the Cosmos ecosystem.
A Decentralized Identifier (DID) is a unique identifier used to represent individuals or organizations, and it is not controlled by a single entity. DID is currently at the forefront of blockchain innovation, empowering individuals to take control of their data and significantly reducing the risk of data theft or manipulation.
DID’s foundation rests on four key principles: decentralization, immutability, interoperability, and privacy. These principles imbue DIDs with immutability, interoperability, security, and resistance to censorship. Consequently, DIDs offer a promising solution for establishing secure and user-controlled digital identities in an increasingly interconnected and data-driven world.
It is worth noting that DIDs are stored on a blockchain, ensuring they are tamper-proof and immutable. Once a DID is created, it cannot be altered or deleted.
DIDs have so many applications, but they mostly fall under three major categories. They include:
DIDs are based on a standard called W3C DID specification. This specification provides a standardized framework for the representation and makes it possible for different applications and services to interoperate and share DIDs.
Essentially, a DID comprises two key elements: the DID identifier and the DID document.
The DID identifier is a unique URI (Uniform Resource Identifier) that serves as the unique identifier for a particular DID. Think of it as a special address that separates one DID from another.
To help you understand, let’s create an example using the name “Abiodun Victoria” for a school certificate DID.
Please note that this example is fictional and created for illustrative purposes. In practice, generating real DIDs and associated documents would involve appropriate cryptographic protocols and security measures.
We’ll create a unique DID identifier using the name “Abiodun Victoria.” Let’s say the DID identifier is: `did:example:abiodunvictoria123`.
Now, let’s create a sample DID document in JSON format for Abiodun Victria’s school certificate:
In this example, the DID document includes the following elements:
Abiodun Victoria can now share her DID (`did:example:abiodunvictoria123`) and the corresponding DID document with relevant parties, such as educational institutions or potential employers. The DID document provides essential information about her school certificate, including her public key, authentication method, the certificate service endpoint, and ownership.
Others can use this information to verify the authenticity of Abiodun Victoria’s school certificate, interact with the certificate service, or establish secure communications using her public key.
DIDs are a key part of the Cosmos ecosystem, and since they are interoperable, it makes it possible for users to have a single, unified identity that can be used across different applications within the ecosystem. This means DID powers seamless identity management and interoperability across multiple blockchains within the Cosmos network.
First, DIDs offer a powerful solution by creating a unified identity that can seamlessly be used across multiple blockchain networks. This breakthrough innovation eliminates the hassle of creating new accounts for every application or service, providing users with easy access to different platforms.
Also, DIDs have completely revolutionized the way user data is shared across different blockchain networks. By maintaining a single, comprehensive identity record, individuals can effortlessly manage and update their personal information. This opens up lots of possibilities, from streamlined identity verification to simplified interactions with government services and even improving job application processes.
Finally, DIDs play a pivotal role in ensuring secure and private cross-chain communication. With DIDs, users can securely transmit messages, data, and tokens across various blockchain networks, safeguarding their privacy while enabling seamless interoperability.
The Cosmos network stands out as an exceptional example of a blockchain ecosystem that fully incorporates DIDs. Designed with interoperability as a core principle, the Cosmos network facilitates seamless communication between different blockchains within its ecosystem. This unique characteristic enables DIDs to be used across multiple blockchain networks within the Cosmos network.
There are several key technical components and protocols that enable DID on Cosmos. They include:
If you made it down here, you could already think of a million ways DID can be incorporated into different walks of life. Here are some real-world use cases of DID on the Cosmos ecosystem:
Decentralized Identifiers (DIDs) present numerous benefits across various walks of life, and we are already witnessing significant adoption of this innovative technology within the Cosmos network. As we continue to explore and understand the potential of DIDs, it is clear that we are only scratching the surface of their capabilities. The adoption of DIDs on the Cosmos network is a testament to the significance and promise of this technology. With its interoperable nature and strong technical foundation, the Cosmos ecosystem provides an ideal environment for the widespread use and integration of DIDs.
