Satograms! Sending Messages over the Bitcoin Lightning Network with Coder Bob

Join the Atlanta BitDevs as we learn about Satograms! Satograms are a technique for mass broadcasting messages across the Lightning network using a technique called keysend. Is it the next wave in marketing? Is it a spam prevention technique? Is it a way to *get paid to receive spam*? Form your own opinion!

[Bitcoin Coder Bob](https://twitter.com/BitcoinCoderBob) is joining us to share his work on this project. We’ll talk about the theory behind it, how it’s implemented on a technical level, fun tales about interoperating with other projects, and more.

🚨 Atlanta BitDevs is a community focused on the development of Bitcoin and related protocols. Our meetup groups are great places to learn if you are interested in working on Bitcoin. Everyone is welcome, but keep in mind that discussions will be very technical! If you are interested in less developer-focused events and just want to learn about Bitcoin in general, we recommend our sister-group Atlanta BitPlebs: [https://www.meetup.com/atlanta-bitplebs/](https://www.meetup.com/atlanta-bitplebs/)
