Technical Foundations of zkSync

zkRollup Technology

zkRollups have seen significant advancements in 2023, particularly with major players like Polygon, zkSync, and Starknet leading the way in Ethereum scalability solutions.

Polygon zkEVM has been a standout, launching its open-source mainnet beta in March 2023, which mimics the Ethereum mainnet’s transaction environment. This development allows for increased throughput and reduced transaction costs, as well as compatibility with all existing smart contracts, tools, and wallets without modification. The technology, which includes Plonky2, enables rapid proof generation and high transaction throughput at reduced costs.

zkSync Era has also made headlines with its full-scale zkEVM, known for its data compression and account abstraction capabilities. It’s particularly lauded for maintaining EVM compatibility, meaning developers can easily redeploy existing smart contracts from Ethereum. zkSync Era has processed over 200 million transactions at an impressive rate, showcasing its robust scalability and user adoption.

Starknet differentiates itself by using Cairo for smart contract development, which while not directly EVM-compatible, offers significant scalability advantages with the potential to handle over a million transactions per second. It utilizes STARK proofs, known for their quantum resistance and scalability. Starknet’s use cases include innovative features like digital will functionalities and automated recurring payments through account abstraction.

All these technologies highlight the potential of zkRollups to greatly enhance the throughput of Ethereum while ensuring security and scalability. Each platform has its unique advantages, whether in compatibility, transaction speeds, or advanced cryptographic techniques, making them essential contributors to Ethereum’s Layer 2 scaling efforts.

Zero-knowledge proofs (ZKPs) are a powerful cryptographic tool that enable the verification of statements or transactions without revealing any additional data about the contents of those statements. They work on the principles of completeness, soundness, and zero-knowledge, ensuring that proofs are convincing and leak no extra information beyond the validity of the assertion itself.

  1. Completeness: If a statement is true, a legitimate prover can always convince an honest verifier of this fact.
  2. Soundness: No deceptive prover can convince an honest verifier of the truth of a false statement, except with negligible probability.
  3. Zero-knowledge: The verifier learns nothing beyond the truth of the statement, preserving privacy and security.

ZKPs can be either interactive, where the prover and verifier engage in a back-and-forth communication to establish the truth of the statement, or non-interactive, where the proof can be verified by anyone without further interaction with the prover.

The implementation of ZKPs offers significant privacy and security benefits, particularly in the blockchain domain where they enhance transaction privacy without sacrificing trust. This capability is crucial in environments like Ethereum, where ZKPs facilitate scalability through mechanisms such as zk-rollups. These rollups bundle numerous transactions into a single proof that can be verified on the blockchain, significantly reducing the on-chain data processing burden and improving transaction speeds and costs.

Further, the versatility of ZKPs extends beyond blockchain. They’re applied in digital identity verification, private transactions, and even in compliance settings where they help reconcile the need for privacy with regulatory demands. As the digital landscape evolves, the role of ZKPs is likely to expand, making them a cornerstone of privacy and security strategies in decentralized applications and beyond.

zkRollups are an innovative scalability solution for Ethereum that significantly enhance transaction throughput while maintaining high levels of security and data privacy. Here’s a breakdown of how zkRollups work:

  1. Transaction Aggregation: Multiple transactions are collected and aggregated into a single batch. This batch processing is executed off-chain, which means that the actual computation and transaction validation happen outside the Ethereum mainnet.
  2. State Transition: Once the transactions are processed, the resulting state change from the batch is computed. This new state needs to be verified on-chain, but sharing all transaction details would be too bulky and diminish privacy.
  3. Validity Proof Creation: To prove the correctness of the off-chain computation without revealing the underlying transaction data, a validity proof (often using cryptographic techniques like zero-knowledge proofs) is generated. This proof is compact yet robust enough to confirm that the transactions in the batch are valid and that they result in the claimed new state.
  4. On-chain Submission: The validity proof is then submitted to the Ethereum blockchain. The mainnet, in turn, verifies this proof, which ensures that the state transition adhered to all of Ethereum’s rules and constraints without needing to process each individual transaction. This significantly reduces the data load on the Ethereum mainnet.
  5. Security and Efficiency: By using zkRollups, the Ethereum network can ensure the security of the transactions through the robustness of zero-knowledge proofs while also offloading the bulk of computational work. This leads to faster processing times, reduced gas costs, and enhanced scalability.

By only requiring the submission of a single proof rather than individual transaction data, zkRollups preserve user privacy and reduce the burden on Ethereum’s mainnet, enabling it to scale more effectively while still leveraging the security and decentralized nature of the blockchain. This approach not only improves transaction throughput but also retains low transaction fees, making it a promising solution for supporting high-volume, complex applications on Ethereum.

zkEVM

The zkEVM, or zero-knowledge Ethereum Virtual Machine, is a transformative adaptation of the standard Ethereum Virtual Machine (EVM) designed to leverage the benefits of zkRollups. This integration aims to maintain the full functionality of the EVM while incorporating the scalability and efficiency improvements provided by zero-knowledge proofs. Here’s a deeper look into how the zkEVM operates:

  1. Compatibility with EVM: The zkEVM is engineered to be fully compatible with the standard EVM. This means it supports all existing Ethereum smart contracts and tools, which allows developers to migrate their applications to zkEVM-based systems without any modifications. This compatibility is crucial for ensuring a smooth transition and wider adoption within the Ethereum community.
  2. Adapting Computation for Zero-Knowledge Proofs: Traditional EVMs process transactions and compute state changes directly on the blockchain. In contrast, zkEVM modifies this process to fit within the zero-knowledge proof framework. Specifically, computations and state transitions are performed off-chain, and only a cryptographic proof of their validity is submitted to the blockchain. This proof verifies that all transactions and state transitions are correct, without revealing the underlying data.
  3. Efficiency and Scalability: By processing transactions off-chain and only submitting a validity proof to the Ethereum blockchain, the zkEVM significantly reduces the computational load and storage requirements on the main chain. This approach not only increases transaction throughput but also decreases transaction costs, making Ethereum more scalable and efficient.
  4. Security: Despite the off-chain computation, the security model of the Ethereum blockchain is maintained. The zero-knowledge proofs ensure that no incorrect transactions can be validated, and the integrity of the blockchain is preserved without exposing any transaction details. This method also enhances privacy and security for users by keeping their transaction data confidential.

The zkEVM represents a major step forward in blockchain technology, merging the traditional functionalities of the Ethereum network with the advanced cryptographic techniques of zero-knowledge proofs to create a more scalable, efficient, and secure ecosystem. This development is poised to drive significant growth in the adoption and functionality of Ethereum-based applications.

Indeed, the zkEVM (zero-knowledge Ethereum Virtual Machine) represents a sophisticated adaptation of the traditional EVM that integrates it within a zk-rollup framework. This adaptation is crucial for maintaining the functionality and flexibility of Ethereum while significantly enhancing its scalability and efficiency through the use of zero-knowledge proofs like zk-SNARKs. Here’s how it fundamentally alters the transaction and smart contract processing:

  1. Data Handling and Privacy: In a zkEVM, data handling shifts significantly to maintain privacy while ensuring compatibility with Ethereum’s existing infrastructure. Rather than posting all transaction data on-chain, only compressed proofs that attest to the correctness of transactions are submitted. This method ensures data privacy and reduces the on-chain footprint.
  2. State Transition Computation: zkEVM modifies the way state transitions are computed by executing these operations off-chain and then generating a cryptographic proof (such as zk-SNARKs). This proof demonstrates the validity of the entire batch of transactions and the resulting state transitions, which the on-chain EVM can then verify without needing to see each individual transaction.
  3. EVM-Equivalence: One of the key goals of zkEVM is to achieve EVM-equivalence. This means that it can support all existing Ethereum smart contracts and DApps without requiring developers to rewrite or substantially modify their code. This is achieved through careful engineering to ensure that the off-chain computation of state transitions and data handling mimics that of the traditional EVM.
  4. Scalability and Efficiency: By processing complex computations off-chain and minimizing the data that needs to be verified on-chain, the zkEVM significantly reduces the computational burden on the Ethereum mainnet. This leads to higher transaction throughput, lower gas costs, and better overall network performance.

The development and implementation of zkEVMs are crucial steps towards resolving Ethereum’s scalability challenges, aiming to provide a seamless, scalable, and secure platform for decentralized applications. This approach not only preserves the robust developer ecosystem built around Ethereum but also introduces significant improvements in transaction privacy and efficiency.

The innovations around zero-knowledge Ethereum Virtual Machines (zkEVMs) and their integration into zk-rollups represent a pivotal advancement for the Ethereum blockchain. These technologies promise significant improvements in several key areas:

  1. Scalability: By processing transactions off-chain and only submitting succinct proofs to the mainnet, zkEVMs reduce the volume of data processed and stored on-chain. This dramatically increases Ethereum’s capacity to handle transactions, addressing one of the most pressing limitations of the current network architecture.
  2. Efficiency: zkEVMs optimize the processing of transactions by reducing the computational load on the Ethereum mainnet. This efficiency not only speeds up transaction times but also lowers gas fees, making operations more cost-effective for users.
  3. Security: Despite the off-chain computation, zkEVMs maintain the integrity and security of transactions through zero-knowledge proofs. These proofs ensure that all transactions are valid and adhere to Ethereum’s rules without revealing any transaction-specific data, thereby enhancing user privacy.
  4. Decentralization: By enabling more transactions to be processed at a lower cost, zkEVMs contribute to the broader goal of decentralization. They allow more users to participate in the network affordably, potentially increasing the decentralization of the network’s user base and governance.
  5. Compatibility: A major advantage of zkEVMs is their EVM-equivalence, which ensures compatibility with existing smart contracts and decentralized applications (DApps). This lowers barriers for developers as they can deploy their existing Ethereum-based applications on zkEVMs without needing to refactor their code, fostering greater innovation and adoption within the ecosystem.

Overall, these technological enhancements are not just incremental improvements; they could be transformative for Ethereum, enhancing its position as a leading platform for decentralized applications by making it faster, cheaper, and more scalable while preserving, and in some aspects enhancing, the security and decentralization that are core to its value proposition.
