Orthrus: Accelerating Multi-BFT Consensus through Concurrent Partial Ordering of Transactions (Extended Version)
Hanzheng Lyu, Shaokang Xie, Jianyu Niu +4
Multi-Byzantine Fault Tolerant (Multi-BFT) consensus allows multiple consensus instances to run in parallel, resolving the leader bottleneck problem inherent in classic BFT consens…
Unraveling Responsiveness of Chained BFT Consensus with Network Delay
Yining Tang, Mohan Yu, Qihang Luo +4
With the advancement of blockchain technology, chained Byzantine Fault Tolerant (BFT) protocols have been increasingly adopted in practical systems, making their performance a cruc…
Fides: Secure and Scalable Asynchronous DAG Consensus via Trusted Components
Shaokang Xie, Dakai Kang, Hanzheng Lyu +2
DAG-based BFT consensus has attracted growing interest in distributed data management systems for consistent replication in untrusted settings due to its high throughput and resili…
TeeRollup: Efficient Rollup Design Using Heterogeneous TEE
Xiaoqing Wen, Quanbi Feng, Hanzheng Lyu +3
Rollups have emerged as a promising approach to improving blockchains' scalability by offloading transactions execution off-chain. Existing rollup solutions either leverage complex…
Ladon: High-Performance Multi-BFT Consensus via Dynamic Global Ordering (Extended Version)
Hanzheng Lyu, Shaokang Xie, Jianyu Niu +3
Multi-BFT consensus runs multiple leader-based consensus instances in parallel, circumventing the leader bottleneck of a single instance. However, it contains an Achilles' heel: th…
Crystal: Enhancing Blockchain Mining Transparency with Quorum Certificate
Jianyu Niu, Fangyu Gai, Runchao Han +3
Researchers have discovered a series of theoretical attacks against Bitcoin's Nakamoto consensus; the most damaging ones are selfish mining, double-spending, and consistency delay…
Phalanx: A Practical Byzantine Ordered Consensus Protocol
Guangren Wang, Liang Cai, Fangyu Gai +1
Byzantine fault tolerance (BFT) consensus is a fundamental primitive for distributed computation. However, BFT protocols suffer from the ordering manipulation, in which an adversar…
An Empirical Study on Ethereum Private Transactions and the Security Implications
Xingyu Lyu, Mengya Zhang, Xiaokuan Zhang +3
Recently, Decentralized Finance (DeFi) platforms on Ethereum are booming, and numerous traders are trying to capitalize on the opportunity for maximizing their benefits by launchin…
Scaling Blockchain Consensus via a Robust Shared Mempool
Fangyu Gai, Jianyu Niu, Ivan Beschastnikh +2
There is a resurgence of interest in Byzantine fault-tolerant (BFT) systems due to blockchains. However, leader-based BFT consensus protocols used by permissioned blockchains have…
Dissecting the Performance of Chained-BFT
Fangyu Gai, Ali Farahbakhsh, Jianyu Niu +3
Permissioned blockchains employ Byzantine fault-tolerant (BFT) state machine replication (SMR) to reach agreement on an ever-growing, linearly ordered log of transactions. A new pa…
EBFT: Simplifying BFT Consensus Through Egalitarianism
Jianyu Niu, Runchao Han, Shengqi Liu +4
We present Egalitarian BFT (EBFT), a simple and high-performance framework of BFT consensus protocols for decentralized systems like blockchains. The key innovation in EBFT is egal…
Fast-HotStuff: A Fast and Resilient HotStuff Protocol
Mohammad M. Jalalzai, Jianyu Niu, Chen Feng +1
The HotStuff protocol is a breakthrough in Byzantine Fault Tolerant (BFT) consensus that enjoys both responsiveness and linear view change. It creatively adds an additional round t…
The Hermes BFT for Blockchains
Mohammad M. Jalalzai, Chen Feng, Costas Busch +2
The performance of partially synchronous BFT-based consensus protocols is highly dependent on the primary node. All participant nodes in the network are blocked until they receive…
Incentive Analysis of Bitcoin-NG, Revisited
Jianyu Niu, Ziyu Wang, Fangyu Gai +1
Bitcoin-NG is among the first blockchain protocols to approach the \emph{near-optimal} throughput by decoupling blockchain operation into two planes: leader election and transactio…
Analysis of Nakamoto Consensus, Revisited
Jianyu Niu, Chen Feng, Hoang Dau +2
In the Bitcoin white paper, Nakamoto proposed a very simple Byzantine fault tolerant consensus algorithm that is also known as Nakamoto consensus. Despite its simplicity, some exis…
