I have never cared about RPC market, but this text is so written in such an interesting way that I read it all. Great submission!

On a related note, we've created a simple, partially decentralised RPC monitoring tool that's free for everyone to use:

It should give you a basic overview of your RPC provider's response latency, how well it's synchronised with the chain tip, and potential errors.

PS: bear with us, it's still an MVP, so the code needs some love.
