Threshold ECDSA in Three Rounds [PDF]
We present a three-round protocol for threshold ECDSA signing with malicious security against a dishonest majority, which information-theoretically UC-realizes a standard threshold signing functionality, assuming only ideal commitment and two-party ...

Efficient Asymmetric Threshold ECDSA for MPC-based Cold Storage [PDF]
Motivated by applications to cold-storage solutions for ECDSA-based cryptocurrencies, we present a new threshold ECDSA protocol between $n$ ``online\u27\u27 parties and a single ``offline\u27\u27 (aka.~cold) party.
