zkSync, an innovative Layer 2 protocol built on ZK Rollup technology, is revolutionizing asset transfers between Ethereum’s Layer 1 and Layer 2 networks. By harnessing the capabilities of Zero-Knowledge proofs and on-chain data accessibility, zkSync ensures seamless and efficient transactions while significantly enhancing scalability on the Ethereum blockchain.

Currently, Ethereum employs two different types of rollups: ZK rollups and Optimistic rollups. In the case of ZK rollups, the transaction batch is meticulously verified for accuracy on the Ethereum network. Once the verification process is successfully completed, the transaction batch is treated as final, akin to any other Ethereum transaction.

The magic behind ZK rollups lies in Zero-Knowledge proofs. The zkSync operator generates proof of validity for a batch of offline transactions. These proofs are then transmitted to Ethereum for the final execution of the transaction batch using a cryptographic technique called SNARK.

The fundamental concept of zkSync is to provide an open and sacrifice-free Layer 2 solution to boost Ethereum’s scalability. Users can now transfer assets via zkSync without encountering tiering issues, the need for new addresses, or any other barriers that might hinder their experience.

zkSync’s benefits extend to both users and developers alike. By significantly lowering transaction fees and enhancing the user experience of crypto wallets and services, zkSync paves the way for exploring new DeFi innovations. This protocol eliminates the reliance on third-party intermediaries, ensures instant transaction confirmation, and reduces fees by up to 99%. Additionally, zkSync enables seamless payments to existing Ethereum addresses and smart contracts.

With zkSync leading the charge in adopting Zero Knowledge rollups, the Ethereum community is poised for a new era of smooth and scalable asset transfers, opening up exciting possibilities for the future of decentralized finance.

Starknet, a pioneering Layer 2 solution, has emerged as a game-changing technology to address the crucial issue of scalability in the Ethereum network. In the past, Ethereum has faced challenges in handling large transaction volumes, resulting in congestion and high gas fees. Starknet’s innovative approach aims to overcome these limitations by utilizing zero-knowledge (ZK) rollups, revolutionizing the way transactions are processed, and enhancing the overall efficiency and security of the Ethereum blockchain.

To understand the significance of Starknet’s impact, let’s delve into the technology behind it. The term “ZK-rollups” comprises two crucial components: “ZK” stands for zero-knowledge proofs, and “rollups” refer to the bundling of transactions into a single, aggregated batch.

Zero-knowledge proofs are cryptographic protocols that allow one party (the prover) to prove the validity of a statement to another party (the verifier) without revealing any specific information about the statement itself. In the context of Starknet, zero-knowledge proofs enable the network to verify the validity of transactions without disclosing the underlying sensitive data. This ensures that transactions are secure and private, a vital aspect for users in the decentralized finance (DeFi) space.

Starknet achieves scalability by employing STARK (Scalable Transparent Argument of Knowledge) technology, a highly secure and efficient cryptographic proof system. With STARK, the prover generates proofs for transactions off-chain, and the verifier checks these proofs on-chain without the need to execute the actual transactions. This process significantly reduces computational overhead, making it more cost-effective and scalable compared to traditional on-chain computations.

The beauty of this approach lies in its ability to create a one-time event for complex calculations. Instead of repeating these calculations across the entire network, Starknet generates a proof once and allows others to verify it, thereby saving considerable time and computational resources. This optimization is pivotal in enhancing Ethereum’s throughput, reducing congestion, and mitigating high gas fees.

Through the integration of ZK-rollups, Starknet enables the bundling of multiple transactions into a single transaction sent to the Ethereum mainnet. By consolidating multiple operations into one, Starknet drastically reduces the number of transactions processed on-chain, leading to faster and more efficient transaction processing.

Furthermore, Starknet embraces account abstraction (AA), which enables greater flexibility in the management of user accounts. AA allows users to interact with the blockchain using a broader range of assets, making it easier to utilize various tokens and assets within the network.

Immutable X

Immutable X, a layer 2 scaling solution, is making significant strides in revolutionizing the NFT and gaming sectors on the Ethereum blockchain. Founded in 2018 by James Ferguson, Robbie Ferguson, and Alex Connolly, the project aims to provide game developers with the necessary infrastructure and software development tools to seamlessly integrate crypto assets into games, thereby streamlining the process and reducing barriers to entry into the web3 gaming world.

Central to Immutable X’s success is its implementation of the Validium StarkEx solution, a cutting-edge Zk rollup technology developed by StarkWare. StarkWare Industries, co-founded by Eli Ben Sasson, an influential figure in the development of STARK and ZCash, focuses on leveraging SNARK proof technology to enhance blockchain scalability and privacy.

The StarkEx framework within Immutable X facilitates the creation of specific rollups, enabling applications such as AMM, Spot Trading, Payments, NFT minting, and trading. Dapps can be deployed in two primary modes: ZK Rollup, which stores transaction data on Ethereum via calldata, and Validium, where transaction data is stored off-chain.

When users conduct operations that modify the network’s state, such as minting or trading NFTs, transactions are generated and processed within the Immutable X chain. The Operator role aggregates and issues transaction batches, sending them to Ethereum with Merkle roots before and after processing the new transactions. In contrast to Optimistic Rollups, which require Verifiers to recalculate and verify the state, Immutable X leverages STARK Proofs, providing a more efficient and timely approach to validating the state of new transactions on Ethereum.

Transaction data on Immutable X is stored off-chain by the Data Availability Committee (DAC), a network of nodes responsible for storing relevant data. In case of disputes, the DAC supplies the necessary data, and each batch of transactions is accompanied by attestations, confirming the availability of data when needed. This approach significantly reduces costs compared to posting full transaction data to Ethereum as calldata.

With its focus on NFT and gaming applications, Immutable X is poised to make a significant impact on Ethereum’s scalability, driving innovation and fostering growth within the web3 gaming ecosystem. As the platform continues to expand its capabilities and integration, it is expected to attract further attention from developers and users alike.
