Encrypted Digital Artefact (EDA)

Silvermind takes a unique approach compared to what is commonly observed in the NFT landscape today. We step back and ensure correct preparation of files intended to become NFTs. Here's why:

• Exclusive visibility: Only the owner (initially the author) can access the original artwork.

• Included license: The artwork is accompanied by the author's prescribed license.

• Preview availability: The artwork can still be previewed, allowing others to have a glimpse of its content.

The final file we call encrypted digital artefact (EDA). It is the file that is going to become the content (artefact) of an NFT.

1. Assemble

Before this stage the artist must have prepared the e-autograph which is the proof of authenticity of the artwork.

Original artwork

The file can be of any format. Silvermind doesn't transform the file, as it would interfere with the initial intention of the artist. Maybe one photographer would want to privide a 20GB png file, whereas another would be working with 100KB jpeg, or several files for different purposes.

License

The license file is optional, but it's a a good idea that artists provide it. Silvermind does not ensure that a collector will respect the license, but at least it will be legally binding.

E-autograph

This is an electronically signed document by the author, which certifies the authenticity of the artwork and consequently the NFT which encapsulates it.

2. Encrypt

When everything is packaged into a zip (or tar) file, we encrypt that file. It becomes the original content that which is sought by a collector. Only the rightful owner will have the key to actually decrypt it into the zip file with the image and license inside of it.

3. Preview

Previews are needed for presentation purposes. Silvermind offers several of them:

1. Autographed preview. It's an image of the artwork, in a high enough resolution to appreciate it on a computer screen. It will have a reference to the e-autograph, which is ultimately a PDF file certifying the authenticity.

2. EDA with a preview. It's an image with "invisible" part where EDA bytes are inserted. Simply put, it's a convenient way to have a zip look like a picture.

3. Thumbnail. A small preview image.
