Hi, I’m Sergei!
I am a protocol research engineer working on blockchains and decentralized technologies, with a focus on security and privacy of off-chain protocols and smart contracts. I hold a PhD from the University of Luxembourg.
My work includes:
- Off-chain payment streams for the Logos P2P network
- Attacks on Bitcoin’s Lightning Network: channel jamming and balance probing
- P2P-based transaction clustering in Bitcoin, Zcash, and Monero
- Static analysis of Solidity for vulnerability detection in Ethereum smart contracts
See Publications for the full list of papers.
