### Dock Labs unlocks Decentralized Identifiers and Verifiable Credentials for your Auth0-powered App.

### <br>

While crypto companies adjust to the [changing market conditions](https://www.cnbc.com/2022/07/14/why-the-2022-crypto-winter-is-unlike-previous-bear-markets.html) in the DeFi space, Web3 innovators continue to build new infrastructure for the decentralized internet. That work took a step forward earlier this month when [Dock Labs](https://www.dock.io/) released their [Auth0 Marketplace Integration](https://marketplace.auth0.com/integrations/dock-web-3-id), Web3 ID, to unlock sign-in with [Decentralized Identifiers (DIDs)](https://dock.io/decentralized-identifiers) and [Verifiable Credentials (VCs)](https://dock.io/verifiable-credentials) and enable privacy-preserving user verification for Web3. 

Using Web3 ID, developers can grant access and verify end-user eligibility by requesting private data from users' non-custodial identity wallet apps with the users' consent.

The DID and VC W3C standards are core building blocks to enable [Decentralized Identity](https://dock.io/decentralized-identity) scenarios. [The Auth0 Lab team](https://twitter.com/Auth0Lab) has been following the space closely, and we're excited to support Dock with this important work.

## The Genesis of Decentralized Identity

The 2010s saw a stream of news on the misuse of identity information ([1](https://www.vice.com/en/article/g5gk73/google-fired-dozens-for-data-misuse), [2](https://www.nytimes.com/2018/04/04/us/politics/cambridge-analytica-scandal-fallout.html), [3](https://www.theatlantic.com/technology/archive/2014/06/everything-we-know-about-facebooks-secret-mood-manipulation-experiment/373648/)). Governments responded with new regulations, like the European Union’s [General Data Protection Regulation (GDPR)](https://auth0.com/gdpr)  and the [California Consumer Privacy Act (CCPA)](https://auth0.com/ccpa). Technologists started thinking about their own solutions for how to design a web ecosystem that doesn't rely on large centralized players to arbitrate identity across the web. While Decentralized Identity won't solve every privacy concern, it will hopefully represent a move towards user control of their data.

One of the core tenets of Decentralized Identity is that users own and control their identity information. In Web2, users sign in with centralized identifiers like email addresses and social media profiles. Web3 users want decentralization, to own their assets and identifiers, and to preserve their privacy while accessing apps and services. Web3 introduced the ability to sign in using cryptocurrency wallets. But with crypto wallets, all the user data that a developer can verify is on the blockchain, like assets owned or transaction history. Putting personal user data on the blockchain can be a major privacy issue, as a public blockchain is immutable and… public.

### Dock Lab's Approach to Decentralized Identity

The need to have a Web3-native system that enables organizations to verify private user data led Dock Labs to build Web3 ID, a blockchain-based Authentication and Authorization system that puts user privacy first. With Web3 ID, users' private data is stored on their non-custodial wallet apps.

However, this notion poses all sorts of challenges. Users need both security and convenience. Traditionally, they offloaded these responsibilities to the major social IDPs, like signing in with Google, which provided both very well, but sacrificed user privacy and control as Web3 organizations realized that getting a user to successfully handle a private key with a wallet [can prove to challenge](https://www.cnbc.com/2021/12/14/common-defi-crypto-related-scams-and-how-to-protect-your-wallet.html).

Another challenge of Decentralized Identity is that it's an ecosystem play; a lot of independent actors need to adopt similar standards so the identity can operate between systems. To ensure that DIDs and their associated public keys are always available for verification, Dock publishes DIDs to a[ public blockchain](https://dock.subscan.io/) that anyone can reference. Even though blockchains aren't required for DIDs to work, blockchains solve ecosystem problems by making the data publicly available for anyone to build against.

In the meantime, the standards for Decentralized Identity are evolving and being solidified. The [World Wide Web Consortium (W3C)](https://www.w3.org/) recently [finalized the DID Core standard](https://www.w3.org/2022/07/pressrelease-did-rec.html.en). The W3C's working on [Verifiable Credentials continues to evolve the standard](https://www.w3.org/TR/vc-data-model/) to fit industry needs. Dock Lab's evolving toolset is keeping apprised and applying these developments.

## Dock in Depth

Dock Labs, the team behind Web3 ID, has been in the decentralized identity space since 2017. "We started Dock to enable organizations and individuals to create and share verified data," says Elina Cadouri, co-founder of Dock.

While Web3 ID allows developers to verify user data in Verifiable Credentials, Dock's Decentralized Identity Platform,[ Certs](http://certs.dock.io/), provides a highly secure and scalable solution to issue these credentials through a no-code dashboard or a simple-to-use API.

And it's all built on top of the Dock blockchain. A Proof of Stake distributed ledger purposely created by Dock Labs for identity use cases, with high throughput, energy, and cost efficiency.

"It's incredibly exciting to see other industries, not just Web3, realize what Decentralized Identity enables. With Verifiable Credentials, sectors like Supply Chain Management or Health & Safety can now issue fraud-proof certificates and instantly verifiable documents. We're helping them eliminate certificate fraud, prove the origin of goods and greatly reduce the time it takes to verify a document." says Nick Lambert, Dock's CEO.
