skipValidation ##\
|
|
## The `skipValidation` flag is used to skip over certain checks that are
|
|
## normally done when an untrusted block arrives from the network. The
|
|
## primary use case for this flag is when a proposer must propose a new
|
|
## block - in order to do so, it needs to update the state as if the block
|
|
## was valid, before it can sign it.
|
|
nextSlot ##\
|
|
## Perform the operation as if the next slot was being processed - this is
|
|
## useful when using the state to verify data that will go in the next slot,
|
|
## for example when proposing
|
|
## TODO need to be careful here, easy to assume that slot number change is
|
|
## enough, vs advancing the state - however, making a full state copy
|
|
## is expensive also :/
