By moving `primitives/transaction.cpp` from `bitcoinconsensus` toThere is a circular dependency that is currently hidden in CMake builds.
chainparams.cpp from `common` requires `primities/transactions.cpp`
`common`, we can keep it and `primitives/blcok.cpp` together in onefrom `bitcoinconsensus` which also depends on `common`. This is
library. This will remove the need to include `bitcoinconsensus` ashidden in every other build by linking `common` before linking
By moving `primitives/transaction.cpp` from `bitcoinconsensus` to
part of the seeder library when the chainparams facilities are`common`, we can keep it and `primitives/block.cpp` together in one
introducedlibrary. This will remove the circular dependency mentioned above.
Discussed previously with Fabien.
