src/avalanche/proof.cpp
118 ↗	(On Diff #30036)	Why does this need to be a lambda?
122 ↗	(On Diff #30036)	This calls for a ternary operator.
src/avalanche/proof.h
72 ↗	(On Diff #30036)	Clearly, this can't be "getHash". What hash? What are these parameters? Can I really pass anything in there?
96 ↗	(On Diff #30036)	This is clearly not a useful API. It happens because you can't decide who's in charge of what.
src/avalanche/proofbuilder.cpp
43 ↗	(On Diff #30036)	If the proof knows to use legacy or not, then it is clear that the switch between the two behavior doesn't belong here.
src/avalanche/proofbuilder.h
30 ↗	(On Diff #30036)	What do I need to pass in there? I can really pass any random crap and I get an appropriately signed stake?
src/avalanche/test/proof_tests.cpp
319 ↗	(On Diff #30036)	You just removed all the test cases for the legacy format.

This revision now requires changes to proceed.Sep 20 2021, 14:45

Cleanup the API by rebasing on top of D10175 and D10179.
By using a strongly typed StackCommitment it is no longer possible to sign arbitrary data.
