The Era of Digital Identity

Lesson 03 Hero Art mobile

Digitization is changing the world. As digital technology advances, storing and accessing your personal information becomes easier and more secure. Long gone are the days of storing the paper trail of your life in a bulky filing cabinet; we are increasingly documenting our identity digitally.

Lesson 03 SideBySide 01
So, what is identity?

The simplest definition would be proof of who you are. The identity system verifies and authenticates you, allowing you to access various resources. Your name, age, home address, email address, medical records, or even the login credentials for your electricity provider's website all contribute to defining your identity.

While the current methods we use to obtain, store, and share these pieces of ourselves work, they are separate and can pose challenges. You might have to put yourself through a lengthy process to get a copy of your ID card if you lose it. Gathering your past medical history can prove difficult if you have to see a new doctor after relocating. Just trying to keep track of all your username logins for your email, bank, school, and so on can be a headache (maybe the new doctor can help with this). Every aspect of your life involves identification of some kind—from housing, to employment, to education, to your medical history, the more you do, the larger this web of identity becomes.

What would it be like if all these pieces of information were owned and controlled by you foremost (not other entities), located in one place, and accessible?

This technology exists, and is evolving each day. In Web3, new ways of thinking about identity are being reimagined to address the next phase of digital identity.

Your Secret Recovery Phrase and your identity

Your crypto wallet allows you to store the information that identifies you  in one place. When you create your wallet, you are given 12 words known as your Secret Recovery Phrase (SRP). The SRP is typically 12 random words that look something like this (note, this is not a real Secret Recover Phrase):

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

These 12 words are the seed of your digital identity and are used to generate  the keys that grant you access to your wallet. The same way you wouldn't give away your bank account PIN number, you wouldn't give away these 12 words: anyone with your SRP will be able to access your wallet and all of the assets held within it. Like at any point in history, where money is involved, so too are bad actors, so it’s important to stay vigilant. To protect your identity and digital assets, you must protect your Secret Recovery Phrase. 

The safest way to protect your identity, or Secret Recovery Phrase, is to write these words down manually—yes, using pen and paper—and store them securely offline, since they’re responsible for protecting your digital identity.

It should never be stored online like in your phone's notes app, or as a screenshot, since it will be vulnerable to hackers anywhere that is internet accessible.

Lesson 03 SideBySide 02
Using your identity: Your Public Address

Once you’ve created your wallet, your public address, often referred to as your public key, identifies all the transactions associated with you. A public wallet address is a string of letters and numbers that represents your account, similar to a bank account number.

It looks something like this:


You can feel free to share your public address, but do keep in mind that if someone searches for your address in a blockchain explorer like Etherscan, they can see the entire history of transactions associated with it. This long string of letters and numbers can be difficult to memorize, although if you like doing that sort of thing, we won’t judge. There are tools to make your account address easier to remember, like Ethereum Name Service (ENS). ENS allows you to register a .eth name and link it directly to your wallet address, websites, and domains.

Similar to email addresses, ENS names are unique and one of a kind. An example of this is vitalik.eth — which actually refers to the public address above. Once registered, nobody else can own the same .eth name unless you sell or transfer it. As soon as you link the ENS to your account, you can provide your ENS in place of that long string of letters and numbers when conducting transactions.

Whether it's research departments in major tech companies like IBM and Microsoft, global standards bodies like the World Wide Web Consortium (W3C), or Ethereum ecosystem innovators like ConsenSys, people around the world are working on bridging Web3 and traditional identity systems, such as those used for traveling, residency, voting, and social security.

The field of digital identity is being thoughtfully and actively researched. Here are just a few examples of the questions being considered by those creating the next phase of the World Wide Web:

What are the ways we can ensure a wallet belongs to its rightful owner and represents a unique individual? How can a user's personal data travel with them throughout their life — online and offline? How can a person's identity and activities be verified accurately and securely without relying on a centralized authority?

Expect rapid advancement over the next few years as the creation, storage, and management of digital identity is revolutionized by Web3.

Remember, your Secret Recovery Phrase is the root of your identity in Web3. Write it down, keep it safe, and do not share it with anyone: not your sister, not your accountant, especially not your tattoo artist.

Key Takeaways

03 Takeaway 03

Secret Recovery Phrase (SRP) 
is the core of my web3 identity.

03 Takeaway 02

SRP needs to be written down 
and placed in a secure location. An SRP is similar to the pin number to your bank card, you would not want to give it to anyone else or let others see it.

03 Takeaway 01

The SRP generates my public account number that is similar to a bank account number, it's how I'm associated with publicly on the blockchain.
