> a blockchain is defined by the property that each block "contains" its predecessors
That's how @cy is defining the term too. I'm wondering what this is based on, because I agree with @soapdog here, my understanding has always been that a blockchain is a special case of an append-only log, that includes a global consensus mechanism. So calling any use of an append-only log a "blockchain" is like calling any use of the net a "website", even if it doesn't use HTTP.
