Definitions
-----------
- ``PostBlossomHalvingInterval`` as-defined in [#zip-0208]_.
We use the following constants and functions defined in [#zip-0208]_:
- ``BlossomActivationHeight``
- ``PostBlossomHalvingInterval``
- ``Halving(height)``
We also define the following constants and functions:
- ``SlowStartShift`` as-defined in [#block-subsidy]_.
- ``HeightForHalving(halving)``: Smallest ``height`` such that ``Halving(height) = halving``

The three consensus-defined funding streams described above each start at the Blossom activation height, and
end at the first block reward halving. They are defined as follows:
