Would it be chaotic to make another blockchain? Will it interfere the current stored data on our computers and make it cross linked in someway!
No; in fact, there are already
dozens, if not hundreds of them (this list does have some errors, like listing Lightning Network as a blockchain).
You can definitely run multiple different blockchains' full node software in parallel, as well. They have their own install and data directories, so nothing should interfere.
Ok, thats good. I was not even sure if that was a question to ask but considering blockchain with its mega data storage and complex algo a computer would go brrrr on its bus lines. Lolz.
So it's the same as having multiple apps on your phone. Let us say multiple wallets with their own universe within the phone environment and no matter how many you install they are not interfering. It's a broken example but that's the closest I could think about technically.
If so, multiple blockchains shall be created and it could lay off bigger burdens from the current blockchain. Imagine the Ordinal NFT getting shaded from the current chain and shifting it entirely on a different one.
