Supposedly someone uploaded a Doom clone to the bitcoin blockchain:
But I'm a bit confused on exactly what is uploaded using "Ordinals". From a quick read of Ordinals, I'm assuming they are just using OP_RETURN and putting in a encoded string into a block or a transaction?
This encoded string uploaded is a "id" that links to a file on ordinals.com? So technically no real files are uploaded like this Doom clone is it? And if ordinals.com is offline, none of these files are accessible?
And how is this different from colored coins or counterparty from about a decade ago?
