|
|
|
|
We can optimize verifying multiple multisignatures by splitting the
|
|
data building into two parts;
|
|
o A large part that is shared by all of the computations.
|
|
o A small part that is unique to each signer in the multisignature.
|
|
|
|
The following methods support that optimization:
|
|
1. startMultiSigningData provides the large part which can be shared.
|
|
2. finishMultiSigningData caps the passed in serializer with each
|
|
signer's unique data.
