About Purramid
A playful, community-driven cat ranking. Upload your feline, collect pawsitive reactions, and climb the pyramid together with the community.
Photos
Gallery with folders, Markdown captions and seasonal frames. You can change the profile photo at any time — just pick any picture from your gallery.
Originals live on-chain: when you mint a photo, it’s written to the blockchain and can’t be altered — it’s yours, permanently. For speed, the site shows a temporary cached copy from our server; the original stays untouched on chain. You also decide what’s public in the Purramid: mint thousands to your wallet and simply mark which ones you want to share.

On-chain
Behind the scenes we use Bitcoin SV (via TeraNode.pl Tools). Every cat can have its own “shelf” in your wallet. When you mint your cat’s identity or a photo, we write a proof to the public ledger — so it can’t be lost or silently changed. You keep the keys, so you keep the ownership. The website shows fast previews; the originals remain preserved on-chain.
