Layer 2 zero knowledge roll-ups have initially been used for achieving private transactions on blockchains. However, past simple transfers, interacting with a public smart contract posed a serious challenge. As research and technology evolved, proof construction became much more efficient, enabling zk-powered scalability. There is a variety of pros and cons for each type of proof system, but given the impending rise of qunatum computers, we have witnessed a recent migration from SNARKs to STARKs. While the former relies on trusted setups, zk-STARKs are quantum-resistant. We were joined by Eli Ben-Sasson, co-founder of Starkware, to discuss Starknet's layer 2 architecture, as well as the upcoming update to Cairo 1.0 and how it will impact scalability performances for STARKs. Topics covered in this episode: Shifting from privacy to scalabilityZK roll-up taxonomy and main differences between SNARKs and STARKsWhy scalability is easier to implement than privacy solutionsConstructing proofs efficiently in CairoStarknet’s layer 2 architectureBuilt-in account abstractionVolition, data availability and trust assumptionsSequencer decentralisation and crypto regulationsStorage proofsCairo upgrades & TPSCouncil-based vs. DAO governanceFuture developmentsEpisode links: Eli Ben-Sasson on TwitterStarknet on TwitterThis episode is hosted by Friederike Ernst.

As Epicenter hits the 500 episode milestone, our hosts look back on almost 10 years of crypto developments, analysing the good, the bad and the ugly. What projects & narratives have surprised our hosts? Has Bitcoin failed in becoming a reliable store of value? Will ZK proofs provide the much needed solution to AI’s alignment problem? Last but not least, are we still early? Get ready for a fascinating discussion, albeit gloomy for this special occasion. Thank you for being part of this amazing journey! We wouldn’t have made it so far without your continuous support! Looking forward to the next 500 episodes!
