Scratch tech is a technology that applies proof-of-work to digital art, i.e. creates multiple variations of an original art piece until the hash of a variation reaches a pre-specified target hash. We call this ‘scratching’
A hash is a sequence of digits that uniquely represents a document. A hash can be viewed as a cryptographic fingerprint of a document. You can hash any digital document (picture, word, video, etc)
In .gif palette scratching, Scratch Tech iteratively creates variations through changes in the palette colors until one variation meets the target hash. In .gif pixel scratching, Scratch Tech iteratively creates variations through changes a few pixels of the image until one variation meets the target hash. At first, we focused on variations with changes unnoticeable to the human eye.
In the SaaS version, you can scratch .gif files up to 10 MB. If you need to scratch a bigger .gif file, this is possible. Please send us a direct request and we will make a custom quote for you.
