AIP: BOLD - permissionless validation for Arbitrum

This Upgrade is another step towards a better future for Arbitrum!!

I think that the Arbitrum BoLD upgrade is a great idea because it makes the network more secure and open to everyone by allowing anyone to help validate without special permissions.

But how will the teams monitoring the upgrade ensure readiness during the restricted execution timeframe?

And how will whitelisting Infura impact the validation and operation of Arbitrum Nova?
