Join us for a live stream of the Stellar Open Protocol Discussion on October 28 at 2:00 PM ET! In these bi-weekly meetings, we discuss and plan for changes to upcoming versions of the Stellar Protocol. This meeting will focus on CAP-21, which generalizes transaction pre-conditions, and paves the way for building payment channels on Stellar. It's a technical discussion, so if you are interested in following along, we suggest reading through that CAP.
