Our paper on the the vulnerabilities of Bitcoin to attacks at the network routing level. Joint Work with Maria Apostolaki and Laurent Vanbever. See the project page at ETH, and the IEEE S&P '17 paper.
Our work on the (lack of) resilience of Bitcoin to strategic mining attacks. We find the optimal way miners can exploit the protocol for their own gain. Work with Ayelet Sapirstein and Yonatan Sompolinsky. Paper from FC'16.
We show how attackers might disrupt Bitcoin's P2P network using an eclipse attack, and propose some changes to alleviate the problem. Joint work with Ethan Heilman, Alison Kendler, and Sharon Goldberg. The paper from USENIX SEC '15.
