1. Presented by: Fabian Vogelsteller @feindura

2. MONARCHY DEMOCRACY

MONARCHY DEMOCRACY

4. DECENTRALIZED SYSTEMS

5. DECENTRALIZED SYSTEMS

6. A copy of the blockchain is stored on each user’s computer.

7. Block Approval

8. It is the shared, collective history of
transactions on the network.

9. Mining

10. IDENTITY
Your signature is regularly
used to verify your actions.

11. YOUR KEY
In Ethereum your signature is your Private-key, which
only you posses.

13. OPEN SOURCE TRUST
“If I have more than $100
in my wallet, I’ll give $10
to Tom.”
People make promises, and sometimes break them.

14. if wallet.balance > 100
then money.giveTo(tom,10)
OPEN SOURCE TRUST
Software does what it is coded to do.

15. OPEN SOURCE TRUST
Open Source software can be seen and audited by anyone.
if wallet.balance > 100
then money.giveTo(tom,10)

16. Contracts can be used to build currencies, financial derivatives,
voting systems, decentralized organizations, data feeds, title
registries and thousands of other applications.
ETHEREUM IS VERSATILE

17. Sending a transaction to a contract causes its code to execute.
Contracts can store data, send transactions and interact with
other contracts.
ETHER IS THE FUEL

18. The more computation a transaction requires the more ether it
consumes.
NOT ALL CONTRACTS ARE ALIKE

19. JavaScript Application interacting with the Blockchain
USING CONTRACTS

20. Ethereum can be used to codify, decentralize, secure and trade
almost anything.
BUILD (ALMOST) ANYTHING

21. Mist is the Ethereum client. It allows decentralized applications
built for Ethereum to be used like any other web application.
