As much as it pains me to say this this might be a good use of blockchain
The Bitcoin whitepaper [0] is a very accesible read, but the revolutionary ideas are not immediately obvious.
The problem is it could be very expensive. Think NFT but the metadata is the source code of the emulator. You're not removing that from the blockchain, ever. It also needs to be a popular blockchain, like ETH, BTC, SOL or whatever people still use today.
There are "coins" where your stake is disk space but if it's not a widespread thing it just dies off (conway GoL style)
