That's a great question :) Outside of fixing human behavior - Blockchain
can be used to keep a tamper proof record of financial transaction that
is much easier for auditing after the fact. So if an RFP is taking place
all of the negotiations and contracts could be digitized and recorded
there. Unfortunately I don't see it fixing what individuals could do
outside of the transaction but where there is a signing and record kept
it could help. Hope that helps!
One of the differences between how blockchains operate versus traditional centralized systems is that information stored within it is more widely accessible by virtue of how its distributed. Lack of transparency and easy/practical access to records is one of the things that helps govt. corruption and this is something moving to blockchains can help with.
