ZK-SNARKs are an innovative method of verifying that a computation has been performed correctly. They form the backbone of many proposed scaling and privacy solutions for Ethereum.
PLONK is a new ZK-SNARK construction, developed by AZTEC and Protocol Labs, that is 'universal'; only one 'trusted setup' is required, and different ZK-SNARK programs do not require additional trusted setups to be performed. This construction is the first universal ZK-SNARK construction that is practical enough for use in smart-contracts.
In this talk, we will provide an overview of how ZK-SNARKs can be used to solve Ethereum's scaling and privacy challenges, and how PLONK opens up a world of zero-knowledge dapps.
