MAD-HTLC Accepted to IEEE S&P 2021

We are excited about the MAD-HTLC paper: it identifies a new HTLC attack variation that applies for Bitcoin-like systems as well, and not just Ethereum; it shows the attack costs are substantially lower than what was previously thought; and, it introduces the MAD-HTLC solution, disincentivizing any of above attacks.

The IEEE S&P conference is a top venue for security researchers and we are looking forward to (virtually) presenting our work there.
