Why Ethereum MainNet Might Not Be Great for Instant Coordination

You know how some blockchains need a boss to keep them in line? That's where a Coordination Blockchain comes in. This one's about Ethereum MainNet, the public Ethereum blockchain, and whether it can handle that job for Ethereum Private Sidechains. These sidechains are like private clubs where blockchains party together and do atomic crosschain transactions. Ethereum MainNet is an open network that wants to be trustworthy and offer incentives for good behavior using crypto. The question is, can it really do that?

Well, yes and no. It's awesome for storing stuff that needs to be widely available for a long time, like info from the Ethereum Registration Authority. But for stuff that needs to be used right away, like Sidechain Public Keys and atomic crosschain states, it's not so great. That's because Ethereum MainNet takes its sweet time to finalize things, which isn't ideal when you need info pronto. So, while MainNet can be a reliable coordinator for some tasks, it might not be the best choice for everything.
