+
+When learning about libp2p, it can be helpful to understand how various projects and applications have integrated and benefitted from libp2p over the years.
+As a modular peer-to-peer networking framework, usage of libp2p can look very different when powering large-scale blockchain networks, vs enabling robust p2p applications, vs underpinning flexible edge computing and agent coordination.
+
+A few notable users of libp2p include:
