During oral proceedings at the EPO this week, the other side's attorneys made a couple of assertions. I have my own views but I'm not an expert in this field and would like to see what others think.

The first assertion was that all transactions in Bitcoin inevitably contain an unlocking script.

The second was that Ethereum doesn't have locking and unlocking scripts.

These turned out to be irrelevant to the validity of the patent we were discussing (which got revoked anyway), but made me wonder whether the other side knew what they were talking about.
