@tolyloom, we should add these details to the whitepaper. They're unique optimizations enabled by proof-of-history.

Yes, but orthogonal.
There's no hash of a set of coins.
There's a hash of each transaction, and each transaction signs an existing hash from the ledger.
Ethereum uses a globally unique counter, as I understand. A performance choke point.
And probably a security hole, since two forks could have the same counter.

Only requires proof-of-order, technically, which Bitcoin implements with UTXOs. That's a clunky way to do it.
