Describe the feature

with lower blocktimes it's more likely that there's a delay during validation and insert, e.g.

validation in block N
N + 1 mined
pool updated
insert in N + 1

we could use the block context (NumHash) during validation in case we need to enforce things like non-noncegap transactions (7702)

TODO

• add block_info: NumHash to validationoutcome
