The Layer of Zero Knowledge | Layer 2 ReviewQuick Reads and Hot Links Covering the People and Projects Who Are Scaling EthereumDear Frens, Welcome to the L2 Review, where we bring you the latest layer 2 updates. The past few weeks have seen significant developments in the L2 ecosystem, and we're here to keep you informed. One of the major developments is Movement’s connection with Polygon’s AggLayer. This initiative opens up altVMs, creating a bridge between these protocols and EVM ecosystems. According to data from Token Terminal, Base now hosts 80% of active Uniswap users. This underscores its growing influence and the increasing adoption of L2 solutions within the crypto ecosystem. Additionally, Artifact Lab has partnered with Eclipse to launch data staking on Ethereum L2, offering users enhanced privacy and new income opportunities. This issue's editorial is a primer into zero-knowledge proofs, the technology that powers zero-knowledge rollups. It promises to be an engaging read. Seat back and scroll on to stay informed about the latest in the world of layer 2s.

Movement Labs has announced its participation in the development of the AggLayer, an extraordinary initiative aimed at bridging the gap between Move and Ethereum Virtual Machine (EVM) ecosystems. This development is particularly exciting because it opens up new possibilities for altVMs (alternative virtual machines), potentially improving how different blockchain ecosystems interact. Movement’s integration into the AggLayer will unify users and liquidity across MoveVM Layer 2 chains, bringing together an impressive $160 million in Total Value Locked (TVL). Movement Labs is also launching a MoveVM public testnet that leverages Celestia's Data Availability (DA) layer. This testnet will integrate with the AggLayer and feature six pioneering projects:
The goal of this innovation extends far beyond just connecting Move and EVM ecosystems. Its ultimate mission is nothing short of unifying the entire web3 landscape. This includes bringing together users, developers, various programming languages, smart contracts, and different blockchain networks – including non-EVM chains and Layer 1 solutions Interested in learning more about this new project?

OptimismPolygonThe Layer of Zero KnowledgeAuthor: Kornekt As Ethereum celebrates its ninth anniversary, scaling problems remain one of the network’s biggest setbacks. The Ethereum community has been building around a rollup-centric model to address these scaling challenges. There are two types of rollups: Optimistic and Zero-knowledge. The model of optimistic rollups is easy to understand – assume transactions are valid unless proven otherwise within a given timeframe. However, comprehending the operations of zero-knowledge rollups (which involve complex cryptographic maths) can be quite daunting. In this article, we provide a simple and beginner-friendly intro to zero-knowledge technology. Zero-Knowledge TechnologyIs it possible to show someone you know something without actually revealing details of that particular thing? Like proving you know a secret without revealing the secret itself? Welcome to the world of zero-knowledge proofs – cryptographic protocols that allow a party (the prover) to prove to another party (the verifier) that they know a value without conveying any information apart from the fact that they know the value. Zero-knowledge proving is a concept that is not native to cryptocurrency but has found wide applications in the industry. Beyond blockchains and cryptocurrency, ZK proofs find application in privacy-focused identity verification, voting systems, supply chain management, and several other sectors. Generally, ZK proving can happen in two forms: Interactive and Non-Interactive. Interactive Zero-Knowledge ProofsIn this type, the prover and verifier engage in a dialogue, with the prover convincing the verifier of their knowledge through multiple rounds of communication. It provides a high level of security and is well-suited for real-time applications. However, interactive proofs require multiple rounds of interaction, and as such are not ideal for asynchronous systems. Non-Interactive Zero-Knowledge Proofs (NIZKs)As the name suggests, these proofs eliminate the need for a dialogue between the prover and verifier. The prover generates a single message that can be verified independently by the verifier. NIZKs are efficient and scalable, perfect for blockchain and other decentralized systems. Although they are slightly less secure compared to interactive ZKPs. Zero-Knowledge Proofs in Layer 2 RollupsSeveral layer 2 solutions use Zero-knowledge technology to prove transaction validity before batching it to the Ethereum mainnet. In essence, these protocols operate in the same way every other rollup would, only that they submit a ZK proof (also known as Validity proof) to confirm the validity of their transactions. Any verifier can compute the proof to ascertain the validity of the transactions without actually going through the transactions one after the other. While it is computation-intensive, ZK proofs provide a faster and more secure method of transaction settlement on the base layer. A Typical ZK Rollup OperationHere’s an outline of how transaction settlement occurs on a typical ZK rollup:
Types of Zero-Knowledge ProofsZK rollups use non-interactive zk proofs which come in different fashions. Here’s a little intro to these proofs: zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge)This is a specific type of non-interactive zk proof (NIZK) that is highly efficient and generates very short proofs. They are based on complex cryptographic assumptions. They are highly secure, efficient, and require no interaction. However, they require complex setups and higher computational requirements. Examples of layer 2 solutions using zk-SNARKs are Scroll and Linea. zk-STARKs (Zero-Knowledge Scalable Transparent Argument of Knowledge)This is another type of NIZK that is based on different cryptographic assumptions than zk-SNARKs. They are more transparent and require no trusted setup. They are scalable, transparent, and post-quantum resistant. A drawback though is that they require larger proof sizes compared to zk-SNARKs. Starknet is an Ethereum rollup using the zk-STARK technology. PLONK (Permuted Lagrange basis for Oecumenical Noninteractive arguments of Knowledge)PLONK is a universal and succinct NIZK that uses a generic setup for various applications. It is versatile and can be used for a wide range of applications. Although it can be more complex to implement compared to other NIZK systems. ZKSync uses PLONK for its state validation. Future DevelopmentsThere are ongoing developments in the scene of zero-knowledge proofs. These developments are aimed at reducing computational overheads and proof sizes, developing stronger resistance to potential threats from quantum computers, EVM compatibility, and other measures to increase effectiveness, developer friendliness, and user experience. Optimism is currently moving to incorporate zk proofs in its OP stack. As the technology continues to advance, we will likely see more protocols adopt zk proofs for increased efficiency in this race to scale Ethereum. 📈 DataTotal Value Locked on L2s surpasses $40 billion!Top Ten Projects by Total Value Locked:🔭 Project WatchArbitrumOptimismTop Projects by TVL in the Last 7 DayszkSyncTop Projects by TVL in the Last 7 DayszkEVMTop Projects by TVL in the Last 7 Days🔥 L2 Fees and Costs UpdateTransaction Fees as of August 1, 2024: |
