Railgun cracks new privacy feature requested by Ethereum Vitalik Buterin

Railgun contributors have built a working prototype of a private multi-signature wallet on Ethereum, a feature that Ethereum co-founder Vitalik Buterin had called for at a Web3Privacy Now meetup in Tokyo. Alan Scott, co-founder of the Railgun Project, told DL News that the wallet hides which users control it and uses the same zero-knowledge proof technology that underpins the Railgun protocol. The design implements Flexible Round-Optimised Schnorr Threshold Signatures (FROST), a method originally created for Bitcoin. The team plans to build a user interface next and demo the wallet at the Devconnect Argentina conference in Buenos Aires.
