FISSION: Label Augmentation for Bot Detection
Sen Yang, Ignacy Nieweglowski, Aviv Yaish
Bot accounts and coordinated influence operations are often discovered via heuristic methods, leaving a dearth of reliable ground-truth labels for training detection systems. To ad…
Crypto x AI, AI x Crypto: A Survey
Sarah Allen, Pranay Anchuri, James Austgen +22
The intersection of crypto x AI is spawning papers, products, online posts, and companies. All the surrounding buzz, though, obscures what exactly has been done, what the opportuni…
The Price of Decentralization in Block Building
Burak Öz, Fei Wu, Luis Correia +3
Decentralized block building mechanisms replace the monopoly of a single proposer with multiple builders. However, their censorship-resistance and fair-access benefits depend not o…
Your Loss is My Gain: Low Stake Attacks on Liquid Staking Pools
Sen Yang, Aviv Yaish, Arthur Gervais +1
Permissionless Proof-of-Stake (PoS) economic security is predicated on the high cost of violating consensus safety or liveness. We show that liquid staking introduces additional ri…
Boost+: Equitable, Incentive-Compatible Block Building
Mengqian Zhang, Sen Yang, Kartik Nayak +1
Block space on the blockchain is scarce and must be allocated efficiently through block building. However, Ethereum's current block-building ecosystem, MEV-Boost, has become highly…
Lifefin: Escaping Mempool Explosions in DAG-based BFT
Jianting Zhang, Sen Yang, Alberto Sonnino +2
Directed Acyclic Graph (DAG)-based Byzantine Fault-Tolerant (BFT) protocols have emerged as promising solutions for high-throughput blockchains. By decoupling data dissemination fr…
Geographical Centralization Resilience in Ethereum's Block-Building Paradigms
Sen Yang, Burak Öz, Fei Wu +1
Decentralization has an important geographic dimension that conventional metrics, such as stake distribution, often overlook. Validator location affects resilience to regional shoc…
Insecurity Through Obscurity: Veiled Vulnerabilities in Closed-Source Contracts
Sen Yang, Kaihua Qin, Aviv Yaish +1
Most blockchains cannot hide the binary code of programs (i.e., smart contracts) running on them. To conceal proprietary business logic and to potentially deter attacks, many smart…
RediSwap: MEV Redistribution Mechanism for CFMMs
Mengqian Zhang, Sen Yang, Fan Zhang
Automated Market Makers (AMMs) are essential to decentralized finance, offering continuous liquidity and enabling intermediary-free trading on blockchains. However, participants in…
Agora: Trust Less and Open More in Verification for Confidential Computing
Hongbo Chen, Quan Zhou, Sen Yang +4
Binary verification plays a pivotal role in software security, yet building a verification service that is both open and trustworthy poses a formidable challenge. In this paper, we…
Decentralization of Ethereum's Builder Market
Sen Yang, Kartik Nayak, Fan Zhang
Blockchains protect an ecosystem worth more than $500bn with strong security properties derived from the principle of decentralization. Is today's blockchain decentralized? In this…
MISO: Legacy-compatible Privacy-preserving Single Sign-on using Trusted Execution Environments
Rongwu Xu, Sen Yang, Fan Zhang +1
Single sign-on (SSO) allows users to authenticate to third-party applications through a central identity provider. Despite their wide adoption, deployed SSO systems suffer from pri…
SoK: MEV Countermeasures: Theory and Practice
Sen Yang, Fan Zhang, Ken Huang +3
Blockchains offer strong security guarantees, but they cannot protect the ordering of transactions. Powerful players, such as miners, sequencers, and sophisticated bots, can reap s…
