Rethinking Collaborative Trust for Verifiably Decentralized Blockchain Systems
Yunqi Zhang, Shaileshh Bojja Venkatakrishnan
Despite the promise of decentralization, measurement studies have identified a conspicuous lack of decentralization in blockchains. Centralization has been observed in almost all l…
Starfield: Demand-Aware Satellite Topology Design for Low-Earth Orbit Mega Constellations
Shayan Hamidi Dehshali, Tzu-Hsuan Liao, Shaileshh Bojja Venkatakrishnan
Low-Earth orbit (LEO) mega-constellations are emerging as high-capacity backbones for next-generation Internet. Deployment of laser terminals enables high-bandwidth, low-latency in…
Less is More: Fairness in Wide-Area Proof-of-Work Blockchain Networks
Yifan Mao, Shaileshh Bojja Venkatakrishnan
Blockchain is rapidly emerging as an important class of network application, with a unique set of trust, security and transparency properties. In a blockchain system, participants…
The Effect of Network Topology on Credit Network Throughput
Vibhaalakshmi Sivaraman, Weizhao Tang, Shaileshh Bojja Venkatakrishnan +2
Credit networks rely on decentralized, pairwise trust relationships (channels) to exchange money or goods. Credit networks arise naturally in many financial systems, including the…
Perigee: Efficient Peer-to-Peer Network Design for Blockchains
Yifan Mao, Soubhik Deb, Shaileshh Bojja Venkatakrishnan +2
A key performance metric in blockchains is the latency between when a transaction is broadcast and when it is confirmed (the so-called, confirmation latency). While improvements in…
Placeto: Learning Generalizable Device Placement Algorithms for Distributed Machine Learning
Ravichandra Addanki, Shaileshh Bojja Venkatakrishnan, Shreyan Gupta +2
We present Placeto, a reinforcement learning (RL) approach to efficiently find device placements for distributed neural network training. Unlike prior approaches that only find a d…
