Earlier this year we partnered with the Zcash Foundation to bring threshold signatures support to Sapling. In this blog we want to share with the community about our progress and some exciting results we got so far. The highlight is that for the first time we were able to run a Zcash full node, patched to support 2 party Sapling shielded transactions. Proof of Concept is hereby released. The blog is highly technical and structured as a series of challenges we faced.
