%gora: Urbit's Decentralized Attestation System

%gora is one of the first apps to have been shipped with Urbit's software distribution system, initially announced at Assembly 2021. It is Quartus's founding product and continues to be its flagship as well as an integration point for additional Quartus software and middleware.

What is gora?

Simply put, it's a platform for making attestations sans central authority.

Anyone running %gora creates/hosts a "token" that contains an image and a title along with some other settings. Once minted, the host can subsequently offer this token to anyone else on the network. The recipients may choose to accept the offer - and thus irrevocably hold that token going forward - or to ignore it.

Examples help:

Others use %gora for... various fun things?

More!

%gora has additional features today - and plenty more on the roadmap - that you'll need to check out for yourself after installing. We'll touch on a few here.

Cults and Gated Access

Thanks to the integration of the %cult wrapper middleware from Quartus, you can use a gora to gate access to a private group. Creating a cult around a particular gora will generate a secret group that only the holders of this special gora can access. We've got a video that goes into greater detail.

Staks

For standard gorae, each recipient holds just a single copy of the token. With a stak-type gora, the host can dole out additional copies to current holders, forming a stak of "points" (seen above in my upvote gora).

Maybe you only want those who have at least 10 of your club's attendance points to have access to the private inner sanctum?

Public / Gossip

By default, newly-minted gorae are in private mode and will only be seen by those to whom they've been offered. However, you can choose to mark a gora as public which will propagate it out to your %pals (and their %pals...) on the gossip network. You can request a gora that you see on the gossip network. It's up to the host to accept or reject your request.

One Protocol, Many Faces

Presently, there are two interfaces for accessing the single %gora agent on your ship.

We believe that one of the promises of Urbit is the way in which UIs can be fungible and personalized without compromising on "backend" consistency. We've begun experimenting with that in %gora but these are merely fun, early steps. There's a lot more to say about this topic, but not here, nor now.

Installing %gora

We'll assume you're already on the network (if not, check out Tlon, Third Earth, Tirrel or a number of other hosts). 

• Install the "light background"/English interface from ~dister-dozzod-dalten

• Install the "dark background"/Japanese interface from ~mister-dozzod-dalten

Oh, and feel free to swap between the two to test them out. Installing from one will overwrite the UI (but not the backend state) of the other.

As always, if you have questions, come find us in our group on the network at ~mister-hilper-dozzod-dalten/quartus or on the doomed-web on Twitter @QuartusCo.
