Well, Wikipedia describes it sufficiently vague: “a database is an organized collection of data”. But is a linked list on its own a database? I’d say the blockchain itself is the data structure but any software using it is most likely a database.

Good summary, a few additions from my side:

• Being public is not required. E.g. banks could form an internal block chain shared only with other banks.
• Blockchains are a database. An immutable and usually distributed database.

Unterstützt Bogen noch x86? Eventuell brauchst du da was spezielleres für sowas. Oder alte Verteilung und weit weg von Netzwerken halten
