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

Which Blockchain Type?Don’t trust, verify
Who are my verifiers? Who am i accountable to?
What resources do those verifiers control?

Blockchain - Anwendungen heute● Digitales Cash● Universelle weltweite Währung● Setzt neue Standards bei der Sicherheit● Spekulation● Basis für andere Finanzprodukte● Tokens, NFTs, Ticketing
Mobilio
● App (iOS & Android) incentivises distraction-free driving
● Drivers collect points that can be exchanged for MOBILIO tokens
● What we did
○ Mobilio’s ERC-20 token (MOB) with special time-dependent minting process, assigning tokens continuously over 100 years
○ Custom Blockchain Backend Service (BBS)
○ Corresponding REST-API communicating between blockchain and MOBILIO App
Qravity
● Decentralized content production and distribution platform where creators own and profit from their work
● Capacity is the lead blockchain development team
○ We designed the Ethereum-based token ecosystem
○ Currently developing the corresponding smart contracts that ensure transparency, fairness and security for Qravity project founders, content creators, distributors, and consumers

storage becomes a commodity like air+water
