Short Paper: On the Claims of Weak Block Synchronization in Bitcoin
Published in Financial Cryptography and Data Security (FC), 2022
We re-evaluates claims that Bitcoin has slow block propagation. We show that block synchronization is actually fast enough, and that previous slow-propagation claims stemmed from bugs and limits in monitoring tools. We finally ask several open-ended questions regarding the technical and ethical issues around monitoring blockchain networks.

Fork State-Aware Differential Fuzzing for Blockchain Consensus Implementations
Published in IEEE/ACM International Conference on Software Engineering (ICSE), 2025
We introduce Forky, a fork state-aware differential fuzzing framework for finding semantic discrepancies in blockchain consensus implementations. We test Forky on Bitcoin and Ethereum, which are the representatives of the two major blockchain consensus algorithm families, PoW and PoS consensus algorithms.

On Frontrunning Risks in Batch-Order Fair Systems for Blockchains
Published in ACM SIGSAC Conference on Computer and Communications Security (CCS), 2025
We examine frontrunning risks in batch-order fair blockchain systems (like Themis [CCS’23]) and propose the ‘Ambush attack’ that enables frontrunning attacks that remain possible despite fair-ordering guarantees.

Published in KIISC International Conference on Mobile Internet Security (MobiSec), 2025
On the Security Risks of Memory Adaptation and Augmentation in Data-plane DoS Mitigation
Published in Network and Distributed System Security Symposium (NDSS), 2026
We introduce ‘Heracles attack’ that uncover security risks in adaptive data-plane DoS defenses in programmable switches, and propose a new sketch mechnaism ‘Shield’ to mitigate Heracles attack.
