What’s Going on with Decentralized Identity on Tezos?

A closer look into some ongoing developments around DID within the Tezos ecosystem.

Welcome to Tezos Bulletin!

We have recently started a new series to coincide with our active Twitter handle and telegram announcement channel, . The goal of this series is to help educate and inform the Tezos and crypto community at large about the latest and ongoing developments within the Tezos ecosystem that perhaps need further examination/insight apart from their rudimentary announcements.

With that said, for the first post in this series, let’s scale back and look at some of the work going on within Tezos around decentralized identity (DID).

DID on Tezos

Awhile back, I wrote a post detailing the work Spruce Systems is doing within the Tezos ecosystem around building out secure and convenient solutions for developers to share authentic data. Since that point in time, a lot has changed and we’ve recently learned about a Korean-based company (FutureSense) incorporating Tezos in its efforts towards implementing DID-based solutions with Korean law enforcement.

Decentralized Identity in the context of blockchain makes a lot of sense as there’s a real and growing problem unfolding before us around data sovereignty and returning data control back to the end user. This issue isn’t a matter of tin foil hat conspiracy theory as it’s well documented.

For a blockchain network such as Tezos that has a tested, well-defined governance process, multiple on-chain upgrades activated autonomously, and the facilitation of formally-verified smart contracts for security to the highest degree — Tezos makes an easy choice.

But, don’t take my word for it.

It has a battle-tested mainnet, active developer community, and smart contracting languages designed to support functional correctness checking using proof assistants.

Its demonstrated an ability to reliably upgrade the protocol to add new features our customers have asked for, such as ZKPs (“zero-knowledge proofs”).

It also has longevity through its on-chain governance system.

So, what exactly is going with DID on Tezos?

Future Sense

In the latest Tezos Foundation bi-annual report, we learned about a new Korean-based company (FutureSense) working on incorporating Tezos-based DID subsystem, data integrity subsystem, and a token-based data marketplace with the NIA National Police Agency in Korea.

I find it peculiar that this wasn’t brought up more in depth. However, for some clarity at the significance of this new development, the NIA National Police Agency in Korea is quite large. The agency has over 100,000 police officers, so naturally, the opportunity to get local law enforcement to incorporate Tezos-based DID solutions knowingly is quite significant.

What remains to be seen is how the efforts from FutureSense manifest in the context of South Korean law enforcement.

Spruce Systems

Spruce Systems is actively developing secure and convenient solutions for developers to share authentic data. In the context of Tezos, Spruce has released several new products and received prestigious funding from Y Combinator.

A few noteworthy developments:

  • Tezos DID Method (did:tz)
  • DIDKit
  • Credible
  • Rebase

Conclusion

When we put these two significant developments around Tezos in the context of DID, we arrive at a picture of not only why these are real problems being addressed — but how they’re being used on a macro level within Tezos. That macro level fits in with all the other developments we’re witnessing today in the Tezos ecosystem.

How these developments all tie in with one another from decentralized identity, asset tokenization, NFT’s, and more — is that they’re providing the necessary network effects for Tezos to grow since public blockchain derive their ultimate value from network effects.

It remains worth watching not only how Tezos continuously evolves, but also how projects like DID will help shape more network effects within the Tezos network.
