[Chicago] Blockchain

I'd describe blockchain as three things: (a) some schema to store
records/events/contracts in, and a serialization method to make them
hashable, (b) a cryptographic method to combine the new record and previous
record's signature to produce a new signature, and (c) keeping signatures
public so other parties can make sure nobody can rewrite history.

As far as I know, and someone please correct me if I'm wrong on any of
this, the distributed system of Bitcoin, et al., is both a method to keep
things public, but also is needed by the schema that stores the records
(goes beyond the essence of blockchain). Also, I think that the actual
record doesn't need to be public. A secret record could be verified to have
been entered into the chain at some point by parties recomputing the next
