Scalability Issues of Ethereum and Layer-2 Solutions

Ethereum has become the primary platform for decentralized applications, bringing profound changes to the finance sector and other industries. However, this growth comes with a notable weakness: insufficient processing capacity to meet the increasing demand. As user numbers grow, transaction fees soar, processing speeds slow down, and the network becomes overloaded.

Ethereum 2.0 is gradually being deployed to address this issue, but Layer-2 solutions offer immediate effectiveness. These technologies enable off-chain transaction processing, supporting a multitude of dApps and new use cases.

ZK Rollup: Breakthrough Technology for Scalability

Among Layer-2 solutions, ZK rollup projects stand out as the most promising technology, combining high performance with strong security. It works by aggregating multiple transactions into a single transaction, similar to how bypass roads help reduce congestion in busy cities.

How It Works

ZK rollup uses cryptographic technology called (zero-knowledge proofs). This technology allows proving the validity of a batch of transactions without revealing the details of each individual transaction. These proofs are extremely compact, reducing data storage on the mainnet and speeding up processing.

The operation process includes the following steps:

On-chain smart contract defines rules and stores core data
Off-chain virtual machine processes most transactions, significantly reducing costs
Create cryptographic proof to verify the integrity of all transactions
Verification on the mainnet by validators to ensure safety

Advantages of ZK Rollup Projects

Increased transaction throughput: By batching multiple off-chain transactions into one, ZK rollup significantly reduces load on the main network.

Lower gas fees: Aggregated data is compact, leading to much lower transaction fees compared to on-chain transactions.

High security: Cryptographic proofs ensure validity without revealing sensitive information.

Fast speed: Verifying batch transactions is faster than verifying each transaction individually.

Better user experience: Transactions are quick, cheap, and less congested, enabling smoother dApp operation.

Ethereum compatibility: Maintains on-chain data to ensure compatibility with existing Ethereum smart contracts.

Environmentally friendly: Reduces energy consumption through efficient processing.

Prominent ZK Rollup Projects

The ZK rollup ecosystem is rapidly evolving, with many new projects shaping the future. Here are some noteworthy projects to watch:

Manta Network (Manta Pacific)

TVL: $851 million
Launch: September 2023 (Testnet)
Governance token: MANTA is used for governance, staking, and paying transaction fees

Manta Pacific is one of the pioneering ZK rollup projects, providing an efficient scalability solution for Ethereum. This project focuses on improving performance and reducing transaction costs.

The ZK rollup ecosystem is still in development, offering many new opportunities for developers and users. The advancement of these technologies promises to address Ethereum’s scalability challenges in the near future.
