Summary

assertBlockchain gives the Blockchain in reverse order, rather than in newest -> oldest order, like most of the other functions which return Blockchain.
It's unclear that this is the case, and you want the newest -> oldest order for functions in Ledger.Blockchain to work.
Ideally this fact should be documented or changed.
