A large number of protocols on Ethereum and Solana blockchains have no revenue

Blockchains store data as long as someone, somewhere has a node. There's no way to purge old data. So old, useless data does build up.

It's not that bad, though. The Ethereum chain is about 1.4TB right now.[1] Growth is roughly linear. Bitcoin is under half a terabyte. Those are manageable numbers given current disk sizes.

The size of the Solana blockchain is claimed to be only 10MB. That's tiny. Where is the data stored?

From the article: "Parts of this article were generated with the assistance from AI tools and reviewed by our editorial team to ensure accuracy and adherence to our standards." Right. That's Coinbase trolling for clicks.

Based on this answer[1] it was 100TB in 2022.

You can absolutely "delete" a protocol if you own the Solana program.

It's not deleted in the sense that all of its history is still on the blockchain. But it is deleted in the sense that the account storing the Solana program no longer exists / is empty and you cannot interact with it. In fact, if you haven't immutably deployed a Solana program, you are heavily incentivized to delete it if it is unused, because then you can recoup the Solana you posted as rent to upload the program in the first place.
