Prism Removes Consensus Bottleneck for Smart Contracts
Gerui Wang, Shuo Wang, Vivek Bagaria +2
The performance of existing permissionless smart contract platforms such as Ethereum is limited by the consensus layer. Prism is a new proof-of-work consensus protocol that provabl…
Proof-of-Stake Longest Chain Protocols: Security vs Predictability
Vivek Bagaria, Amir Dembo, Sreeram Kannan +5
The Nakamoto longest chain protocol is remarkably simple and has been proven to provide security against any adversary with less than 50% of the total hashing power. Proof-of-stake…
Boomerang: Redundancy Improves Latency and Throughput in Payment-Channel Networks
Vivek Bagaria, Joachim Neu, David Tse
In multi-path routing schemes for payment-channel networks, Alice transfers funds to Bob by splitting them into partial payments and routing them along multiple paths. Undisclosed…
Practical Low Latency Proof of Work Consensus
Lei Yang, Xuechao Wang, Vivek Bagaria +5
Bitcoin is the first fully-decentralized permissionless blockchain protocol to achieve a high level of security, but at the expense of poor throughput and latency. Scaling the perf…
Deconstructing the Blockchain to Approach Physical Limits
Vivek Bagaria, Sreeram Kannan, David Tse +2
Transaction throughput, confirmation latency and confirmation reliability are fundamental performance measures of any blockchain system in addition to its security. In a decentrali…
Bandit-Based Monte Carlo Optimization for Nearest Neighbors
Vivek Bagaria, Tavor Z. Baharav, Govinda M. Kamath +1
The celebrated Monte Carlo method estimates an expensive-to-compute quantity by random sampling. Bandit-based Monte Carlo optimization is a general technique for computing the mini…
