Snarks for mixing, signaling and scaling

Duration: 01:01:28

Speaker: Barry Whitehat

Type: Talk

Expertise: Intermediate

Event: Devcon 4

Date: Oct 2018

There is general interest in the ethereum community to scale ethereum by moving dapps inside snarks. The key to do this is to make an efficient signature function available inside a snark. We present this signature function https://github.com/barryWhiteHat/baby_jubjub_ecc designed to work efficiently inside a snark. Furthermore we describe an architecture to scale ethereum using snarks. We discuss the trade offs required and compare them to building a dapp inside the evm.
