This simplifies things a lot, but don't we also want to have a nonce in the header? It might be useful to have for contracts.

The nonce in the block is an unreliable random number, and contracts should not rely on it.

We can even keep the same header size by removing this 1.

We have already discussed this before. 😆

Back when ac52765 initially added Ledger I've used neo-project/neo#2215 as a reference and it was correct (no primary index). But then neo-project/neo#2296 came into the C# codebase and while it looked like a pure refactoring it actually did add the primary index as well and this wasn't noticed. It wasn't noticed even when 3a4e0ca had touched some nearby code. In short, we had a completely wrong implementation of this call for more than three years. But looks like it's not a very popular one. Signed-off-by: Roman Khimov <roman@nspcc.ru>
