Was ist eine “Blockchain”?

● Jeder Block ist ein unveränderlicher Datensatz(beinhaltet Transaktionen, etc.)

● Referenzierung auf vorhergehenden Block(am Anfang ein “Genesis”-Block)

● Die Blöcke müssen von allen akzeptiert werden● Mehrere neue Blöcke?

→ Längste Kette ist die “Wahrheit”Wikipedia, CC-BY-3.0

Wann spricht man von einer Blockchain?● Die Kernfunktion ist die Anordnung der

Transaktionen, sodass keine Konflikte entstehen können

● Welche Blockstruktur, welcher Konsensalgorithmus und welche Interpretation gewählt wird, sind optional

storage becomes a commodity like air+water

What is capa.space / what will it be● Smart Contracts living on any Blockchain● Network of Hosts/Validators/Replicators● Protocol + Encoding Specifications● SDK for Windows, Mac, Linux + more● A Framework for any Storage Application
