Hi folks. I'm posting this in ~creative because I want to see what other artists think of it; the technical side is important too, but artists and art are the focus of this project.

Cryptographic Digital Art Tokens are a concept I've been working on for a while, to provide some of the benefits of crypto tokens without perpetuating the harm they create.

CDATs are not NFTs. They are not designed to facilitate investment, but rather collection. They do not use a blockchain and do not rely on distributed consensus at all. Instead, they use traditional cryptography to validate the ownership of art.

How CDATs Work

Let's say an artist Adam creates a piece of art called One. He decides he wants to sell a CDAT of One, so he creates a CDAT key and publishes his public key on his website, adam.art.

A collector, Beth, decides she wants to buy One. She e-mails Adam and they agree on a price, and exchange keys; once she has paid, Adam sends Beth a CDAT, which he has signed. Beth then cross-signs the CDAT and sends it back to Adam. It ends up looking like this:

=== CDAT DATA ===
Artist: Adam <adam@adam.art>
Collector: Beth <beth@betawork.codes>
Date of Sale: 2021-12-08T19:50:56Z
Title: One, a Digital Story

Artist Key Fingerprint: c634d0420f825b91
Collector Key Fingerprint: 3b2e3bbf91ec96c2
=== CDAT SIGN ===

=== CDAT META ===

Work URL: https://adam.art/art/one.zip
Artist Key URL: https://adam.art/static/cdat.key
Collector Key URL: https://betawork.codes/
=== CDAT OVER ===

In an ideal world, with all the software enablement I want to do, Beth would be able to take this token and put it in a digital gallery or on her website, where the art piece, and her ownership of it, would be proudly displayed for all to see in a user-friendly, beautiful format.

Structure

The CDAT has three sections - DATA, which is signed, META, which is not, and SIGN, which contains the CDAT's cryptographic signatures. Hashes and key fingerprints are in the DATA section, but URLs are in the META section, which means they can be changed later; artists and collectors can re-host their art and keys, so long as the files' hashes or fingerprints remain exactly the same.

Semantics

Because the CDAT is cross-signed, anyone can see that both Adam and Beth have agreed to the sale. Assuming the signatures and keys all check out, Beth can now prove to people that Adam sold her his art, and Adam can prove that Beth bought it.

Implementation

In order for this interaction to work, we technically need only existing technology: you can validate such things with GPG and some manual reordering. Ideally, though, we'd have a few tools:

• A CDAT validation program. This should include a command line program and a GUI (maybe even a mobile app?), and would validate the following information:
  • The given signatures are valid and correct for the given CDAT.
  • The keys used to sign the CDAT match both the given fingerprints and identities.
  • The linked key URLs, if any, in fact point to the indicated keys.
  • The linked art and cover URLs, if any, in fact point to files with the given hashes.
• A CDAT creation program. This should include a command line program and a GUI. It would take as input the relevant keys and names, provide a way to set the date, and ensure that everything relevant is online at the given URLs.
  • This program would be used by both artists (to create CDATs) and collectors (to cross-sign CDATs).
• A CDAT hosting service. Obviously there could be more than one of these, and people could host their CDATs and art on their own machines - that's decentralization, baby! - but it would be very nice to be able to host CDATs, art, and keys for free or a nominal fee.

This would be a great start, but in order to really kick-start the ecosystem, it would be nice to provide some additional enablement software, such as:

• A drop-in HTML embed that uses client-side JavaScript to display and validate CDATs on a website.
• A browser extension which validates CDATs found on arbitrary websites, on the user's request.
• A self-hostable CDAT gallery for artists and collectors which displays who owns what, and which art pieces are still for sale.

Please let me know if this idea is interesting to you, and ask any questions/leave comments!

Howdy folks.

Had a recent interest in large-scale art projects, and I'm not sure where to start looking to find more.

Anything that by nature has to exist outside of a museum. I'm looking for big displays. Whether it be large scale performance art, buildings erected at the will of an artist, or things like the Dumb Starbucks event that took place out in Los Angeles.

Installments that took any measure of great coordination, investment, or raw personal effort.

I feel like I'm doing a right shit job of describing this - but maybe you get the idea. If anyone has links to news articles, blog posts, or whatever about these kinds of art please drop a comment!

So once a year artists all over the internet settle down and attempt Inktober, where we abandon our digital tools and attempt to put out paper-and-ink drawings once a day for the full month of October! There's "official" prompt sheets and the like, but a lot of us focus on just getting the art made rather than going by a list of ideas to draw.

I never make it the full month, but we're three days in now and I'm currently 3 for 3!

Anyone else taking part? I'd love to see what you've made!

In honor of starving artists everywhere, the topic for this thread is "scant".

• Feel free to open it up to interpretation as literal or loose as you'd like
• Whatever medium works best for you! Even though I labelled the thread as "visual", it would be great to see work from any writers or musicians if any would like to participate as well.
• Entry should be your own work
• Multiple entries are great if you feel inclined

@userexec won the last round of the Visual Weekly Activity. I don't want to steal the glory, but I also got ants in my pants. So this is an unofficial thread and hopefully userexec will chime in with a new official thread when they have time.

Edit: moved the user tag down so the main topic is more visible.

I'M ALIVE!!!!!
Sorry about that; my get up and go got up and went without me. I wandered out of funkland today just in time to be a week and a day late.
<_<

For this week, you may use any media you like - photos, sketches, paints, collage, et. al. to portray BLUE. In any sense of the word. Posting and up voting will cease when the 16th is over and done with.

If you end up with the most votes appreciating your piece(s), you will have the honour to decide the theme to the next week's thread! If that's not enough I'm sure I can find a gif of people grovelling in your magnificent wake. \o/

We've been having a smattering of art, poetry, and photo participation posts, such as this, and this, and this, and this.

We seem to have enough ~tilders to have a schedule of sorts, but not enough to have each activity every week. How about we rotate weekly activities for a while and see how it goes? I'm thinking we have enough interest for a series of visual/craft based threads and a series of writing based threads. For example:

July 3-9th Photography (subject exploration or technique)
July 10-16th What are you making now?/Speedart
July 17-23rd Photography (topic or equipment)
July 24-30th What are you making now?/Media challenge

July 3-9th Freestyle Writing (up to a thousand words)
July 10-16th Themed Drabbles
July 17-23rd Poetry format challenge
July 24-30th It was a dark and stormy night

Please note that these are suggestions and not an arbitrary bid to codify content or become TEH LEADER. I just think it would be fun to have an activity to look forward to every week. We could even just sign up for hosting a week's topic, and whoever is in charge of the week picks the activity.

What does everyone think?

Okay, it's been a little while since the last speedart thread, but I think we are ready for another one! All the same rules apply.

Remember, the purpose of this thread is not necessarily to create a masterpiece, but to encourage people to dedicate some time each week to improve their art as well as providing critique and support. Thus this thread is open to all either as constructive critics and/or artists!

There is no official theme, but if you are looking for inspiration checkout this month's Pictures of the Day over at Wikipedia Commons.

Now grab your materials, set a timelimit, and get creative!
