Non-interactive Mimblewimble transactions, revisited

Authors: Georg Fuchsbauer, Michele Orrù


Mimblewimble is a cryptocurrency protocol promising to overcome notorious blockchain scalability issues. To this day, one of the major factors hindering its wider adoption is the lack of non-interactive transactions, that is, payments where only the sender needs to be online. We start from a proposal by Yu that adds non-interactive transactions to stealth addresses to Mimblewimble, but which turned out to be flawed. Using ideas from Burkett, we propose a modified scheme and analyze it using the provable-security methodology.
