After giving a whirlwind tour of what Ethereum and Solidity are I will show how to use Django and Web3py to deploy a smart contract that performs division.

3. Who is this person? (on the right)

6. What is a blockchain?

7. Like twitter instead of tweets you
store events and everyone hosts
each other.

8. A peer to peer distributed ledger
is a blockchain.
(Entries are immutable once
confirmed)

9. You have a pointer to the
next event (tweet).

10. Everyone has a copy of the
blockchain (peer to peer)

11. And everyone sees every
operation (public
blockchain).

12. "nonce":
"0x0000000000000
042",

13. "difficulty
"0x000000100",

14. "timestamp":
"0x00",

15. EVM is a “scripting
language” on the
Ethereum Blockchain.

16. Solidity is the most
popular / well
developed EVM
Language

17. Q:What is the “Hello world
of solidity?

18. Make your own Token
