# The `skipXXXValidation` flags are 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. Also useful for some testing, fuzzing with
|
|
# improved coverage, and to avoid unnecessary validation when replaying trusted
|
|
# (previously validated) blocks.

skipMerkleValidation ##\
|
|
## When processing deposits, skip verifying the Merkle proof trees of each
|
|
## deposit. This is a holdover from both interop issues with the malformed
|
|
## proofs and, more currently, nim-beacon-chain's creation of proofs which
|
|
## are inconsistent with the current specification. Furthermore several of
|
|
## the mocking interfaces deliberately do not create Merkle proofs. Whilst
|
|
## this seems less than entirely justifiable, for now enable keeping those
|
|
## in place while minimizing the tech debt they create. One, in principle,
|
|
## should be able to remove this flag entirely. It is not intrinsically an
|
|
## expensive operation to perform.
|
|
skipBlsValidation ##\
|
|
## Skip verification of BLS signatures in block processing.
|
|
## Predominantly intended for use in testing, e.g. to allow extra coverage.
|
|
## Also useful to avoid unnecessary work when replaying known, good blocks.
|
|
skipStateRootValidation ##\
|
|
## Skip verification of block state root.
|
|
skipBlockParentRootValidation ##\
|
|
## Skip verification that the block's parent root matches the previous block header.
