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…
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…
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…
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…
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…
A Secure Consensus Protocol for Sidechains
Fangyu Gai, Cesar Grajales, Jianyu Niu +2
Sidechain technology has been envisioned as a promising solution to accelerate today's public blockchains in terms of scalability and interoperability. By relying on the mainchain…
Selfish Mining in Ethereum
Jianyu Niu, Chen Feng
As the second largest cryptocurrency by market capitalization and today's biggest decentralized platform that runs smart contracts, Ethereum has received much attention from both i…
