A very clever part of the HUYGENS algorithm is that it doesn’t just sync clocks pair-wise, it leverages a natural network effect where a group of pair-wise synchronized clocks becomes transitively synchronized, helping reduce errors further without requiring specialized hardware. That’s one of the key reasons it can achieve ~100 nanoseconds of software-based sync on commodity networks.
