WOW, this is perfect, I read that we can add videos into the blockchain by this thing! Amazing, just imagine sending child porn, government secrets as NFTs.
People already do some of that, see https://www.righto.com/2014/02/ascii-bernanke-wikileaks-photographs.html.
They link to CSW as the original creator of Bitcoin, to their software that requires top-grade hardware to run a full node and list CoinGeek as a 'Trustworthy source of Bitcoin news' What I'm trying to say: this garbage is what happens when you allow people to store any data on your blockchain. Fucking disgusting.There's no need to create new side-chain. RSK and Liquid could do that. In fact, i would recommend those people to use RSK which is decentralized and secure thanks to merge mining with BTC network.
