Getting a Sequencer Signature
Blocks must be cosigned by the Sequencer. The Sequencer blindly signs any number of candidate blocks for the current Builder via a simple API.
The Sequencer API accepts a SignRequest via a POST call to the /signBlock endpoint, and returns a SignResponse. For details on calculating the contents hash, see the rust builder example.
The sequencer is allowed to modify the returned copy of the SignRequest. This is to allow the sequencer to set a specific gas_limit. It currently does not modify the request before returning it, but may do so in the future.
