class MerkleBlock:

Below, I have the 2 solutions to the two exercises respectively:

I matched it up with the original book solutions and it looks correct from what I can tell.

I tried "MerkleBlock" instead of "merkleblock" and I'm still getting the NameError.

Yes, I hit the same issue. I resolved it by adding import merkleblock to the top cell in the notebook that loads all the dependencies.
