Welcome! This is a group for developers in and near San Francisco to learn about Ethereum and to aid in developing decentralized applications (Dapps). We have meetings on development tools for Ethereum, example contracts, in-depth looks at various companies, and on the technical details of the Ethereum protocol, and sometimes other layer 1 protocols as well. See also our sister community, the Silicon Valley Ethereum meetup (http://www.meetup.com/EthereumSiliconValley/). We'd love to have you join us!
