The San Francisco Ethereum Developer Meetup focuses on sharing experiences among Ethereum developers and aims to create decentralized applications (dApps) together. Key topics include useful developer tools, examples of tutorial dApps like Tic Tac Toe and HODL ETH Coin, and resources such as Truffle and Mix for development management and debugging. The event also mentions upcoming workshops and discount codes for participants.

MEETUP
BUILDING DAPPS (1/3) - OVERVIEW OF THE MOST
USEFUL ETHEREUM DEVELOPER TOOLS

2. GOALS OF THE
MEETUP GROUP
- place to exchange experiences for active Ethereum
developers
- short term: a bunch of overview and tutorial talks
Lets create some DAPPs together!

3. GNOSIS - ONE OF THE
FIRST FULL DAPPS

4. 3 SIMPLE TUTORIAL
DAPPS (1/3) TIC TAC TOE
- tic tac toe on the blockchain
- small „test framework“ for decentralized decision making
contracts

5. (2/3) HODL ETH COIN
- decentralized coin that is basically free but still has some
scarcity
- lock x ETH for y days in a contract and create x*y HODL
coins
- have a look at https://github.com/ethereum/wiki/wiki/
Standardized_Contract_APIs

6. (3/3) WRITE OR DIE
Still haven’t written your thesis/ this blog post/ this doc/ …?
commit your self to do it.
Lock up x ETH - specify your goal („3 pages of my thesis“) -
send the link/hash to your writing to the contact
Oracle will decide wether you get the money back or whether
it will be destroyed/ sent to an „opponent“
