Yes, the ledger is the key.

A block chain is actually a singly linked list.  Typically blocks contain
transactions, which when added up form a ledger.

In a centralized ledger system, you have central authorities saying who has
what.  e.g. National currencies, equities, gift cards.

In a distributed ledger system, you have a consensus protocol and actors
saying who has what.  e.g. bitcoin, ripple, alts

In a decentralized ledger system, there is no central authority saying who
has what, but transactions are possible between ledgers based on mutually
beneficial rules.  e.g. linked data, the web
