Multicast is one of those terms you'll probably only encounter if you're deep in learning about Internet engineering. It lets a single sender deliver data to multiple recipients at once. Given how much content we consume simultaneously (live sports, major events), you'd think multicast would be everywhere, right? Yet most of the Internet relies on unicast, which is only one sender and one recipient. So even if ten people in the same neighborhood are streaming the same event, ten copies of that event are being sent over the network. Multicast feels like the Internet’s silver bullet, but it's been limited mostly to core and private networks, while the last mile (where the consumption actually happens) is largely untouched. This is exactly why I'm so excited about what my good friend @oaliramadan is building at @BlockcastNet. Many know Omar as "the multicast guy," but his real vision is even bigger -- combining multicast with an edge-based CDN. This is exactly how tech moves from niche engineering to solving real problems at scale. Content delivery needs help scaling, and Blockcast brings new technology, in new locations, and a model that leverages existing infrastructure folks already have. And the protocol that governs this technology intersection between content and the orchestration of how it's delivered, has to exist. The opportunity is too meaningful -- networks today have a 10x efficiency upgrade just waiting to be tapped by the right orchestration layer. We're soon going to be live streaming historical moments like the Artemis moon landing with hundreds of millions, maybe billions watching simultaneously. The current Internet is simply not ready for events of this scale. Content and its delivery are deeply intertwined, and I'm thrilled to help make Omar’s vision a reality. Especially for wireless networks like DAWN, optimizing airwaves is critical. We've got some exciting research with Blockcast coming out soon on this and more. Stay tuned.
