A Geography-Based P2P Overlay Network for Fast and Robust Blockchain Systems

Numerous blockchain systems with various consensus protocols have emerged to achieve high transaction rates (2∼10K tps). However, their underlying P2P network primitives constrain further improvements due to two problems (i) high message redundancy …

FRing: Augmenting Blockchain System Efficiency and Security with a TEE-Facilitated P2P Overlay Network

Project FRing includes a noval peer-to-peer overlay network protocol which improves communication efficiency and security among peers, and an implementation of the protocol in C++.
