A New Trinsic Platform Walkthrough

IMPORTANT UPDATE: This blog post describes a product Trinsic no longer offers, and is retained for archival purposes. Trinsic’s journey, including its pivot to its current product (digital ID acceptance infrastructure) from a SSI/decentralized identity platform, is outlined in this post.

New to Trinsic and looking for a quick way to learn how it all works? We got you covered with a full technical walkthrough of the Trinsic platform, courtesy of Trinsic’s co-founder and CTO Tomislav Markovski. This walkthrough was originally presented at did:hack 2023 and is a great tool to learn the fundamental capabilities of Trinsic.

Below we include a brief intro to Trinsic, breakdown the platform walkthrough, and share resources on how to get started building with Trinsic.

Trinsic is an enabler of verifiable credential products

If you are reading this now, you most likely have identified a problem within a certain industry, use case, or workflow that verifiable credentials can solve. You need to build the perfect product that implements verifiable credential technology in order to make your solution real and adoptable. Trinsic is the ideal verifiable credential infrastructure partner to do just that.

Trinsic takes care of all of your infrastructure needs, so you can focus on the following two things:

1. Building an incredible product

2. Selling that product to an ecosystem of users

While you are focused on your product and users, Trinsic takes care of things like, credential issuance, credential verification, identity wallet creation, ecosystem governance, scalability, interoperability, and more so you don’t have to, saving your team time and resources.

Trinsic’s platform walkthrough

In Trinsic’s platform walkthrough below, you will be shown reference applications for issuing a verifiable credential and verifying the credential on a website. The video will also demonstrate how to use governance with verifiable credentials and will end by talking about Trinsic’s future plans and additions. Below we have included links to the resources used within the walkthrough as well as timestamps for your convenience.
