one runners thought. wikipedia should be a validity rollup. anyone can permissionlessly verify prs, merges, etc. with a node on their smart phone. 

in a world where disinfo and social attacks are the norm the public needs trustless verification. ethereum endgame can provide this.

I like crypto nerd snipes, please forgive me in advance.

can use a consistent stream of rpgf to pay for da costs. 

you could argue a rollup is overkill and a validium is all you need. i dont’t understand the tradeoffs well enough to make that distinction.
