Optimal Flexible Consensus and its Application to Ethereum
Joachim Neu, Srivatsan Sridhar, Lei Yang +1
Classic BFT consensus protocols guarantee safety and liveness for all clients if fewer than one-third of replicas are faulty. However, in applications such as high-value payments,…
Coded Transaction Broadcasting for High-throughput Blockchains
Lei Yang, Yossi Gilad, Mohammad Alizadeh
High-throughput blockchains require efficient transaction broadcast mechanisms that can deliver transactions to most network nodes with low bandwidth overhead and latency. Existing…
Light Clients for Lazy Blockchains
Ertem Nusret Tas, David Tse, Lei Yang +1
Lazy blockchains decouple consensus from transaction verification and execution to increase throughput. Although they can contain invalid transactions (e.g., double spends) as a re…
Longest Chain Consensus Under Bandwidth Constraint
Joachim Neu, Srivatsan Sridhar, Lei Yang +2
Spamming attacks are a serious concern for consensus protocols, as witnessed by recent outages of a major blockchain, Solana. They cause congestion and excessive message delays in…
Securing Parallel-chain Protocols under Variable Mining Power
Xuechao Wang, Viswa Virinchi Muppirala, Lei Yang +2
Several emerging PoW blockchain protocols rely on a "parallel-chain" architecture for scaling, where instead of a single chain, multiple chains are run in parallel and aggregated.…
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…
High Throughput Cryptocurrency Routing in Payment Channel Networks
Vibhaalakshmi Sivaraman, Shaileshh Bojja Venkatakrishnan, Kathy Ruan +5
Despite growing adoption of cryptocurrencies, making fast payments at scale remains a challenge. Payment channel networks (PCNs) such as the Lightning Network have emerged as a via…
RSPP: A Reliable, Searchable and Privacy-Preserving e-Healthcare System for Cloud-Assisted Body Area Networks
Lei Yang, Qingji Zheng, Xinxin Fan
The integration of cloud computing and Internet of Things (IoT) is quickly becoming the key enabler for the digital transformation of the healthcare industry by offering comprehens…
