Add a builders blacklist for ePBS #14385

Open potuz opened 3 weeks ago

We need to keep a blacklist of builders to not take bids from and not gossip bids from. Otherwise a single builder can poisson the p2p stack by submitting high bids. This cache needs to be checked against crucially in two places

How do we decide on which builders should be added to this blacklist?

Edit: Reply from terence: it's subjective and more of an open design. Example: builder revealed an invalid block. Builder revealed a late block under observation. Buildn't revealed a valid block but didnt reveal any blobs... etc
