Zero Knowledge Proofs: From Theory to Applications
Channel: Epicenter Podcast
Date: 2023-01-14

Zero knowledge proofs offer privacy and scaling solutions for Ethereum, in the form of shielded transactions and zk-rollup solutions. By aggregating multiple transactions (several orders of magnitude beyond Ethereum's limitations in terms of TPS) and only publishing a validity proof on L1, zk-rollups are the go-to solution for solving scalability (and privacy).
In this video we summarise all the episodes we hosted on this subject, going back as far as 2016. We wanted to create a narrative arc for the ZK ecosystem, capturing its evolution from a purely theoretical field to practical use cases.

Topics discussed in this episode:
0:00 - Trusted setup phase
2:42 - SNARK
3:18 - Optimistic vs. ZK rollups
3:51 - How transactions are aggregated (sequencer)
4:54 - STARK (vs. SNARK)
6:20 - SNARK vs. STARK vs. bulletproofs
8:06 - Integrating smart contracts (arithmetic circuits)
10:11 - Proof construction & privacy (Aztec's Noir)
11:04 - zkEVM (Hermez)
11:47 - Scalable, shielded transactions
12:30 - Privacy vs. public state (Aztec)
