The purpose of this project is to produce a unique audio-visual / representation of the signature / signature of an Urbit adress. It takes the two words eg "master" "masrze" (or 4 sigils 'mas','ter','mas','rze') as input, and creates a combined output :
- a graphical colored representation of the planet
- a sequence of sounds
Both sound and image are one-to-one unique, making it less error-prone. Only one of the two digital media is enough to verify the signature, even though theoritical.
It uses following components:
- https://processing.org/ for the 3D modeling and audio generation
Unicity is achieved by combining prefixes-suffixes to generate one wave/chord. For the graphical part, we use a combination of (subject to change)
- Color, rotational speed, rotational angle, lightning angle. For the sound, we use a use a chord in C Major scale
- Run an executable from one of the folders included on the /build folder.
- Download and install processing from: https://processing.org/download
- From the Processing IDE open the planet.pde file.
- Press run
Once the software is running, just type the name of your planet (Eg. ~master-master) and press Enter.
To do list / Next Steps :
- Make it match the stars/planets galaxy constellation

What is Urbit ID? Urbit ID is a decentralized address space infrastructure designed for Urbit OS. Urbit ID is the Identity system of Urbit, consisting of 2^32 (4.294.967.296) unique identities. Urbit IDs are distributed hierarchically. At the top of this hierarchy there are 2^8 (256) galaxies. Each galaxy issues 2^8 stars, making a total of 2^16 (65K). Stars then each can issue 2^16 planets, making for a total of 2^32 (~4B). Each of the identities has its own point on the network, its Azimuth point and a corresponding unique pronounceable name with a tilde before it, like: ~wolref-podlex. Galaxies can be found at the first 256 points, Galaxy ~zod is for example azimuth point 0, the Stars that are spawned under a galaxy are placed from point 256 onwards Planets are the 4 billion points from 65.536. If we look at the table below we can identify that ~wolref-podlex is a planet and its Azimuth point is 4.880.309. You can find out more about Urbit IDs here https://urbit.org/understanding-urbit/urbit-id and you can look up all the information about specific Urbit IDs and their parent here https://urbit.live/.
| Tree | Amount | Example name | Azimuth point |
|---|---|---|---|
| Galaxies | 2^8 (256) | ~zod | 0 |
| Stars | ~2^16 (65.280) | ~barwet | 46.949 |
| Planets | ~2^32 (4.294.901.760) | ~wolref-podlex | 4.880.309 |
Besides the Azimuth points, all Urbit IDs have a pronounceable name composed of fragments of three letters that are referred to as syllables. ~zod is a galaxy and consists of one syllable, a star like ~barwet is composed of two syllables and a planet of four syllables. In total there are 512 unique syllables that can be divided in prefixes and suffixes 2^8 (256) each. A galaxy only uses a suffix while any combination of two or more syllables is built with prefixes and suffixes. Example: ~zod ~barwet ~wolref-podlex
A more extensive explanation of Urbit phonetic names and their relation to the numerical addresses on the network can be found here.
At the end of the doc there is a list of all prefixes and suffixes.
At this moment @p's are visualized via Urbit's sigils that create different shapes for prefixes and suffixes and combine them into a unique visual representation of the @p. Below you can find an example of the three visual representations.
~zod ~barwet ~wolref-podlex
More information about how sigils are created and the rationale behind it is here. The rarity of shapes and combinations can be found here.
