Decentralized and distributed systems are likely to continue to gain adoption in numerous fields. With the proliferation of Internet-of-Things, smartphones, vehicles and embedded data centers, mesh networking becomes an important 6G enabler providing flexible deployment and resilient connectivity. We propose to use blockgraph, a mobility-aware blockchain-like data structure to secure this environment. We present in this paper the performance of our solution and provide arguments for the utility of blockgraph for future 6G mesh networks.
