PeerAssets Media

1. 01

   The picture is cut into pieces of 247 bytes, each written into its own Peercoin transaction.

2. 02

   The NFT is a PeerAssets deck (one of one) whose spawn transaction spends the last piece, and commits to the SHA-256 of everything.

3. 03

   Reading starts at the deck and walks back through the pieces. Anything that can fetch a transaction by its id can do it.

4. 04

   Owning follows PeerAssets: the deck's one card, which moves from address to address.

It adds nothing to PeerAssets itself: a PeerAssets Media NFT is an ordinary deck and card, so existing PeerAssets software still sees it. Media up to 1 MB costs about 19 PPC per MB in network fees.
