At present, our lives are more and more related to the apps and companies we use.
An eCommerce retailer to buy on-line, a social community to work together with, an e-mail system for work communications—the checklist goes on.
Utilizing these companies requires proving our id and authorizations. Whereas we’re used to giving out low-level id info, reminiscent of names and e-mail addresses, different companies could require a high-level ID like a Driver’s License.
Nonetheless, present id administration methods have a number of flaws.
Not solely are they centralized, with service suppliers storing person information, however they’re additionally dangerous since malicious actors can breach servers and steal your info.
Decentralized id improves on present id administration requirements and offers customers larger management over private information.
In a decentralized id framework, people retailer their id info and select what to share with third events.
As a result of decentralized identifiers are saved on distributed ledgers and blockchains, they’re tamper-proof, safe, and immediately verifiable by anybody.
This reduces the necessity to retailer id info in servers and makes it simpler for customers to entry companies seamlessly.
This text explains what decentralized id means intimately, the way it works, and why it issues. We’ll cowl key ideas like decentralized identifiers and decentralized authentication and discover present decentralized id initiatives.
Let’s dive in!
What Does Decentralized Id Imply?
Decentralized id is a brand new type of id and entry administration (IAM) that de-emphasizes centralized storage of person info. Decentralized id bolsters people’ management of their information—therefore additionally it is referred to as self-sovereign id (SSI).
In plain English, a decentralized id lets you personal your id. So how does it work in apply?
Your id is a group of attributes and credentials that uniquely describe you. Some identifiers could also be self-owned, like your title, DOB, e-mail deal with, username.
And others could also be issued by establishments; for instance, a college diploma, Driver’s License, or passport quantity.
In decentralized id administration, customers retailer credentials and private info in a “digital pockets.” Identical to a real-life pockets, a digital wallet holds your identifiers, reminiscent of your license or ID card.
Decentralized id distributes the storage of id info throughout a system of distributed computer systems, like a distributed ledger or blockchain.
The usage of distributed ledgers to carry id parts renders them proof against alteration and theft. So, although your id info is recorded in digital format, it can’t be altered, stolen, or deleted.
The transparency inherent in distributed ledgers makes id info immediately verifiable with out essentially counting on the issuer.
Right here’s a short illustration of how decentralized id works:
A corporation (the Division of Motor Automobiles) needs to challenge you (the person) a credential (Driver’s License). You ship your pockets deal with, which is a particular location on the distributed ledger or blockchain for storing information. The DMV then sends the credential to your digital pockets, signing the transaction with its personal key.
Now, you’ll be able to share this credential anytime it is advisable to set up your id—for instance, whereas finishing a mortgage software. Utilizing a trusted utility, the opposite get together can test the validity of your credentials. On this case, the utility checks the general public keys and transaction particulars to substantiate the issuing group and date of issuance.
Be aware that the data itself is just not saved on the blockchain. As an alternative, the blockchain generates an immutable document of the transaction that noticed the data cross from the issuing group to you. This “digital fingerprint” (additionally referred to as a hash) is exclusive to every credential and might reliably show your possession.
The varied gamers in a decentralized id ecosystem embody:
-
Customers: People who personal and use items of id info. Customers like you’ll be able to maintain numerous identifiers in a digital pockets and share them on an as-needed foundation.
-
Issuers: Organizations and establishments that challenge credentials and claims to customers. This may be your native Tax Workplace, an employer, an educational establishment, and any entity that may challenge id info.
-
Verifiers: Third-parties who want id info to ascertain belief and grant entry to companies. For instance, a web based store might have proof of your age or citizenship earlier than permitting you to buy sure objects. Any info you present would must be verified correctly.

How does a Decentralized Identifier Work?
The World Extensive Internet Consortium (W3C) defines a decentralized identifier (DID) as a type of verifiable, decentralized digital id. A DID may be created for any entity, together with a corporation, particular person, or perhaps a gadget.
Designed to be user-controlled, DIDs are saved in a decentralized structure, like peer-to-peer networks or a distributed ledger as an alternative of a centralized registry. As such, a DID is cryptographically safe, proof against adjustments, and verifiable with out relying on the unique issuer.
Decentralized Identifiers and Verifiable Credentials
Verifiable Credentials complement DIDs and energy decentralized id administration. The W3C defines verifiable credentials as “verifiable credentials symbolize statements made by an issuer in a tamper-evident and privacy-respecting method.”
When a college points an educational certificates, it’s “claiming” that the recipient has undergone training for a sure interval. Equally, a vaccination passport is a declare that you’ve obtained the vaccine.
Whereas these claims exist already as bodily paperwork, utilizing them on-line poses a number of issues. Lets say a Know Your Buyer (KYC) course of requires importing your diploma Driver’s License to confirm your age throughout a KYC registration.
First, the service supplier can not affirm the declare’s authenticity. Second, your personal info is now saved on a number of servers, growing the danger of id theft. Third, you want entry to a bodily copy of your license—for those who misplaced it, then you definately can not show your id.
Verifiable credentials resolve these issues in 3 ways:
- Utilizing zero-knowledge proofs to show the validity of claims information with out revealing personal info
- Utilizing public-key cryptography to confirm claims issuers
- Storing claims info on Verifiable Knowledge Registries (blockchains, distributed ledgers)
Utilizing our preliminary instance, you would not must add the whole Driver’s License throughout the KYC. As an alternative, you possibly can simply share a hyperlink to the Verifiable Credential.
Verifiable Credentials use zero-knowledge proofs to guard the privateness of ID holders. Zero-knowledge proofs assist show the authenticity of data with out revealing the whole info to a 3rd get together.
Let’s use the instance of a Driver’s License to elucidate how ZK-proofs may shield your privateness:
The service supplier received’t really see your delivery date listed on the license. Nonetheless, the credential will determine the issuer (the DMV) by way of the general public key. For the reason that DMV solely points licenses to people inside a sure age-range, then we will assume that your age declare is appropriate.
How Verifiable Credentials (VCs) work. Supply: Tykn.tech
VCs are immutably saved on the blockchain, that means you’ll be able to entry them insofar as you may have your pockets and personal keys. They can’t be destroyed, modified, stolen, or deleted. Extra importantly, they are not below the management of the issuing group.
Verifiable Credentials are an essential constructing block of decentralized id administration. With VCs, we will create digital variations of bodily credentials and use them on-line with out having to reveal extra info than mandatory. Third events can simply affirm the veracity of those credentials with out counting on the issuing establishment.
What’s Decentralized Authentication?
The COVID-19 pandemic has quickly accelerated the shift to a digital life-style. Now, it’s possible you’ll select to do issues like banking, videoconferencing, communication, and purchasing from the consolation of your own home.
Accessing these platforms requires verifying your id and permission to make use of these companies. For instance, a banking web site could ask you to supply an e-mail deal with and a password.
Nonetheless, conventional authentication may be fairly problematic. Not solely do it’s a must to create a number of logins for various companies, however you will need to keep in mind each, or danger dropping entry.
Customers could reuse passwords throughout a number of websites to make on-line authentication simpler, however that solely will increase the danger of id theft. If a hacker steals one password, they will simply impersonate you on a dozen completely different platforms.

Federated authentication is without doubt one of the present options designed to make on-line authentication simpler and safer. Right here, a gaggle of entities agrees to depend on one supply for id info. A very good instance of federated authentication is logging in to a web site along with your Fb or Google account.
However federated authentication is hardly a silver bullet. Your id info continues to be hosted on a central server (Fb and Google), so the danger of an information breach or id theft continues to be there.
Federated authentication methods depend on third-party companies to confirm id. Supply: apievangelist.com
Decentralized authentication is a more recent idea the place customers can achieve entry to on-line companies utilizing verifiable credentials. Say you wished to entry a web based banking service. As an alternative of submitting ID paperwork, you possibly can submit a Verifiable Credential from a authorities physique to show your id.
This removes the necessity for the financial institution to request and retailer your info earlier than granting you entry. And also you received’t want an account to login sooner or later because the service supplier can challenge a Verifiable Credential for ongoing verification. Logging into the location could be so simple as connecting your digital pockets!
