Identity can be described simply as proof of your existence and uniqueness. It functions through a system that verifies and authenticates who you are, enabling access to various services. Factors like your name, age, address, email, medical records, and even the credentials you use for online services are integral to defining your identity.

Although the current systems for managing our identity details are functional, they are disjointed and come with several challenges. Losing your ID can lead to a tedious process of replacement. Similarly, relocating and transferring your medical history to a new doctor can be cumbersome. Managing numerous usernames and passwords for different accounts like your email, bank, and school is often frustrating. Identity verification is pervasive across various aspects of life, such as housing, employment, education, and health, creating a complex web that grows as we expand our activities.

What if you had full ownership and control over all your personal details, consolidated in one accessible location? Such technology is not just a concept but a reality that evolves daily. In the realm of Web3, innovative approaches to identity management are continually being developed, pushing forward the evolution of digital identity.

Your cryptocurrency wallet consolidates your identifying information into a single location. Upon setting up your wallet, you are assigned a Secret Recovery Phrase (SRP), which consists of 12 random words. An example of such a phrase (which is not usable) might include:

witch / brown / cat / coven / bollywood / flower / bottle / phone / orange / camper / light / ear

These words form the cornerstone of your digital identity, generating the keys that enable access to your wallet. Just as you would safeguard your bank PIN, you should equally protect these words. Possession of your SRP by others could lead to unauthorized access to your wallet and its contents. In the financial world, where the potential for fraud exists, it is crucial to remain alert and secure your digital identity by guarding your Secret Recovery Phrase diligently.

After setting up your cryptocurrency wallet, it generates a public address, also known as your public key. This key acts as a unique identifier for all your transactions, analogous to a bank account number.

For example, a public wallet address may look like this:

0xd8da6bf26964af9d7eed9e03

You can safely share this public address. However, remember that anyone using a blockchain explorer such as Etherscan can view all transactions linked to it. While memorizing this complex string of characters may be challenging, there are tools available to simplify this task, such as the Ethereum Name Service (ENS). ENS enables you to create an easier-to-remember .eth name, which links directly to your wallet address, websites, and domains.

Like email addresses, each ENS name is unique—take "vitalik.eth" as an example, which corresponds to the public address mentioned above. Once claimed, an ENS name is yours alone unless you decide to sell or transfer it. With an ENS linked to your account, you can use it instead of the lengthy numeric string during transactions.

Significant efforts are underway by research teams at major tech companies like IBM and Microsoft, global standards organizations like the World Wide Web Consortium (W3C), and Ethereum innovators like Consensys. These groups are focused on integrating web3 technologies with traditional identity systems used for travel, residency, voting, and social security.

The domain of digital identity is under intense scrutiny and development. Key questions being explored include how to ensure a wallet belongs exclusively to its owner, how user data can remain portable and secure throughout their life, and how identities and activities can be verified accurately without central oversight.

The field is poised for rapid development as web3 technologies continue to transform how digital identities are created, stored, and managed.

Always remember: Your Secret Recovery Phrase is the cornerstone of your identity on web3. Securely write it down, store it safely, and never share it—not with family, not with financial advisors, and certainly not with your tattoo artist.
