In the first part of this series, we explored how packet loss accumulates in block and fountain codes—even in simple network topologies such as daisy chains—and how the recoding capability of RLNC effectively mitigates this issue. In this follow-up article, we examine hierarchical topologies, such as trees, which have been adopted by Web3 protocols such as Monad and Solana. We present a simple example demonstrating that, even in tree-based architectures, RLNC can outperform both Raptor and Reed–Solomon (RS) codes by achieving lower latency.
