Ethereum scaling solutions often resort to tradeoffs, sacrificing security or decentralisation in favour of scalability. However, zk rollups hold the potential of increasing throughput, while also inheriting the layer 1’s security. This is achieved through zero knowledge validity proofs, which are published on Ethereum mainnet. The final hurdle remains the sequencer decentralisation. zkSync was designed around EVM-compatibility, offering custom scaling solutions through its hyperchain architecture.We were joined by Alex Gluchowski, co-founder &amp; CEO of Matter Labs, to discuss the zk rollup landscape, its bottlenecks, and what makes zkSync stand apart as the most popular rollup.Topics covered in this episode:High-level overview of zero knowledge proofsZK rollupszkSync EraZK ecosystem taxonomyRollup performance: bottlenecks &amp; tradeoffsBridging between zkSync hyperchainsData availability.

Alex Gluchowski: zkSync – The First EVM-Compatible zkRollup Protocol

John Adler

James Prestwich

Guests:Alex Gluchowski (@gluk64)John Adler (@jadler0)Host:Richard Yan (@gentso09)James Prestwich (@_prestwich, special co-host)Today’s motion is “ZK rollup has a better set of security/scalability tradeoff than Optimistic rollup.”Rollups are a class of layer-2 Ethereum scalability solutions. They allow an off-chain aggregation of transactions inside a smart contract. Users can transact inside the contract with security guarantees, and they will settle to the mainchain at some future point.ZK and optimistic rollups are different in the way they ensure the validity of these transactions that are being kept off-chain.The ZK approach uses math. It bundles the transactions, compresses them, and adds a zero-knowledge proof that indicates the validity of the state transitions. When the transaction is sent to the mainchain, the block is verified by the attached zero-knowledge proof.The optimistic approach uses economic incentives. An operator publishes a state root that isn’t constantly checked by the rollup smart contract. Instead, everybody hopes that the state transition is correct. However, other operators or users can challenge the validity of the transactions, revert the incorrect block, and slash malicious operators.We compared the two approaches from the standpoint of security, usability, capital efficiency of exits and more.Today’s debaters are John Adler and Alex Gluchowski. John is the proposer of the original construction of the optimistic rollup and cofounded Celestia, and Alex is implementing a ZK rollup at Matter Labs. Our co-host James Prestwich is a security consultant and auditor for solidity contracts, among many other things.If you’re into crypto and like to hear two sides of the story, be sure to also check out our previous episodes. We’ve featured some of the best known thinkers in the crypto space.If you would like to debate or want to nominate someone, please DM me at @blockdebate on Twitter.Please note that nothing in our podcast should be construed as financial advice.Source of select items discussed in the debate:Coindesk's layman guide for rollups: https://www.coindesk.com/ethereum-dapps-rollups-heres-whyAlex Gluchowski on the difference between the two rollups: https://medium.com/matter-labs/optimistic-vs-zk-rollup-deep-dive-ea141e71e075John Adler explains optimistic rollup: https://medium.com/@adlerjohn/the-why-s-of-optimistic-rollup-7c6a22cbb61a Celestia: https://celestia.org/Fuel Labs: https://fuel.sh/Matter Labs: https://matter-labs.io/Debater bios:Alex Gluchowski is co-founder of Matter Labs, currently working on scaling Ethereum with zkSNARKs.

Motion: ZK rollup has a better set of security/scalability tradeoff than optimistic rollup (Alex Gluchowski vs. John Adler, co-host: James Prestwich)

How can Ethereum scale to thousands of transactions per second?In this episode, I am going to be reading “Introducing zkSync: the missing link to mass adoption of Ethereum” by Alex Gluchowski. In this article, Gluchowski and his team at Matter Labs announces their vision for zkSync: a trustless scaling and privacy solution for Ethereum that has the potential to boost Ethereum’s current throughput of 15 transactions per second to thousands per second. Gluchowski dives in deeper about the specific features for zkSync. He acknowledges the challenges of staying decentralized, enabling privacy, and meeting UX expectations.

We go down the rabbit hole with Alex Gluchowski, CEO of Matter Labs that's unchaining #Ethereum. He shares his thoughts on preserving privacy, how tech is empowering human rights, and what social impact the public blockchain has on the world.

We go down the rabbit hole with Alex Gluchowski, CEO of Matter Labs that's unchaining #Ethereum. He shares his thoughts on preserving privacy, how tech is empowering human rights, and what social impact the public blockchain has on the world.

Blockchain for Social Impact with Alex Gluchowski

On this Shelter-In-Place Episode, we talk to Alex Gluchowski, co-founder of Matter Labs. We talk about his parents fleeing European HyperInflation and how cash (dollars) was king there. We hear about his political introduction to Libertarianism and why it makes sense to him. We discuss his Crypto awakening, and whether or not he hodled. We also talk about Matter Labs and their roadmap for increasing scalability while remaining secure and private with ZKproofs (Zero-Knowledge Proofs) and other tools they’ve developed. We learn about some other projects he’s excited about and get his take on MakerDAO’s Black Thursday/Swan Event. Hit Play to hear all this, off-chain, supported by DSOTHM’s LFCKproof protocol (Lunar-Full-CryptoKnowledge).

035: Ukrainian HyperInflation, German Libertarian Politics, Bitcoin/ETH/DeFi and more w/ Alex Gluchowski

Alex joins us on Base Layer to talk more about zero knowledge proofs and what they are doing at Matter Labs. Initially found by a tweet from Ari @ BlockTower, Matter Labs recently revealed their vision for ZK Sync: a trustless scaling and privacy solution for Ethereum based on ZK Rollup". We discussed that in heavy detail, including tx receipts but also addressed Matter Labs mission which they discussed in their blog: "A successful solution to the scaling problem in public blockchains is not only a matter of high transaction throughput. It must also be defined as the ability of the system to meet the demands of millions of users without sacrificing decentralization. The prerequisites of mass crypto adoption  include high speed, low cost, smooth UX, and privacy." All this and more with Alex from Matter Labs.
