Proof of Backhaul: Trustfree Measurement of Broadband Bandwidth
Peiyao Sheng
Network and Distributed System Security (NDSS) Symposium 2024 · Day 1 · Network Security
The talk "Proof of Backhaul: Trustfree Measurement of Broadband Bandwidth" by Peiyao Sheng introduces a groundbreaking protocol designed to securely and transparently measure the broadband backhaul link capacity of wireless access points in decentralized wireless networks. This innovation is critical for the burgeoning ecosystem of open networking initiatives, where individual participants and small enterprises host network nodes and require performance-based incentives for their contributions. The core challenge addressed is the need for a **Byzantine fault-tolerant network telemetry system** that can verify network performance without relying on a centralized, trusted authority.
