Identity is the perception of oneself and is shaped by distinctive attributes. It encompasses the notion of being an individual, a unique human entity, and can extend to non-human entities like organizations or authorities. An identifier serves as a reference to a specific identity, commonly taking the form of a name, mobile number, tax ID number, place of birth, or date.
Digital identity emerges naturally from the utilization of personal information on the internet and the accompanying shadow data generated by one’s online activities. Presently, conventional identity systems are disjointed, insecure, and exclusive. However, blockchain technologies like Ethereum offer a solution, providing a secure, unified, interoperable, and tamper-proof infrastructure. This not only enhances the management and storage of digital identities but also brings key advantages to enterprises and users. In this blog, we will delve into Ethereum’s impact on digital identity.
How is Ethereum transforming digital identification?
Ethereum is not just a crypto; it functions as a blockchain platform, facilitating the creation of decentralized applications (DApps) and smart contracts. Its practical applications span across many industries. Ethereum’s blockchain is valuable for establishing secure and decentralized systems for managing identities. Storing identity details on the blockchain empowers individuals with more control over their data, streamlining processes like Know Your Customer (KYC) verification.
Digital identity is increasingly integral to the global social and economic well-being of individuals. It plays a crucial role in exercising fundamental rights such as voting, utilizing banking services, and accessing education. However, the challenges in current identity management systems underscore the need for reforms. Blockchain technologies like Ethereum offer an ideal platform for revolutionizing digital identity management. Ethereum has the potential to establish decentralized identifiers and the ability to link digital identity with verifiable credentials. This enables the consolidation of digital identities from various platforms into a single identity that the individual controls and owns. Utilizing Ethereum for decentralized identity brings benefits such as non-custodial login solutions, relief from cumbersome paper-based identity systems, and quicker, simpler, and more secure digital ID verification.

Ethereum-based Identity Solutions
The Ethereum name service, or ENS, functions as a decentralized system for on-chain, machine-readable identifiers, including Ethereum wallet addresses and metadata. Its mechanism resembles the structure of the internet, where website addresses consist of random numbers and domains create a navigational map. ENS aims to establish a comparable directory for human identity using their “.eth” naming convention. In a bid to revolutionize traditional login verification, ENS Labs and the Ethereum Foundation collaborated on the “Sign-in With Ethereum” initiative in 2021. This open-source alternative to logins from major platforms like Apple, Google, and Facebook allows users to seamlessly utilize their ENS.eth name whenever they encounter the “Sign-in with Ethereum” option. This approach ensures users maintain self-sovereign control over their identity while accessing various supported applications.
Spruce ID is a decentralized identity initiative that enables users to oversee their digital identity using Ethereum accounts and ENS profiles, eliminating dependence on third-party services. This project empowers organizations to oversee the complete lifecycle of digital credentials, encompassing items like mobile driver’s licenses, professional certifications, software audit statements, and similar documents.
The Ethereum Attestation Service (EAS) functions as a decentralized protocol designed for on-chain or off-chain attestations covering a wide range of subjects. Users have the flexibility to generate schemas and provide attestations on EAS, with the option to create custom schemas tailored to their specific needs. EAS operates seamlessly with just two Ethereum Smart contracts—one for registering attestation schemas and another for making attestations on those schemas. It offers a straightforward yet versatile solution with limitless potential.
The Future of Digital Identity with Ethereum
BNS (.btc), Lens (.lens), and Polygon ID are self-sovereign identity naming systems in competition with ENS. BNS, which stands for Bitcoin Naming System, presents a self-sovereign identity framework secured by the Bitcoin blockchain. The primary hurdle for these identity providers is challenging the existing dominance of “Big Login,” controlled by Apple, Facebook, and Google. Although .eth, .btc, .lens, and similar systems may appear as competitors, it’s noteworthy that they also gain advantages from being mutually compatible with each other.
The Ethereum Name Service marks a significant move in closing the divide between the complex blockchain world and the user-friendly interface commonly found in traditional systems. Ethereum plays a vital role in streamlining interactions with Ethereum addresses, thereby promoting the widespread acceptance of blockchain technology. Positioned within the dynamic evolution of decentralized identity, Ethereum serves as a symbol of innovation, unlocking fresh opportunities for the advancement of decentralized applications in the future.
