Author: Akindele Hambolu; Translation: Huohuo/Blockchain in Vernacular

**As the adoption of decentralized applications (dApps) and blockchain technology continues to soar, scalability and privacy have become key challenges. **The growing demand for faster and more secure transactions requires innovative solutions that can effectively address these issues. A promising breakthrough in this area is zkEVM Validium, a novel approach to combining zero-knowledge proofs (zk) with the Ethereum Virtual Machine (EVM).

In this article, we explore the benefits of zkEVM Validium and how it has the potential to revolutionize blockchain scalability and privacy.

1. Enhanced scalability

Traditional blockchain networks, such as Ethereum, often face scalability bottlenecks due to limited throughput. The Ethereum Virtual Machine (EVM), while powerful, can only handle a limited number of transactions per second (TPS). ** This limitation leads to high gas fees and slow transaction confirmation during periods of network congestion, hindering mainstream adoption and user satisfaction. **

**Polygon Technology's zkEVM Validium solves this scalability problem by offloading most of the transaction processing to a secondary layer or "Validium Chain". **The Ethereum main chain only verifies the cryptographic proofs generated by the Validium Chain, which significantly reduces the computational burden on the main chain. As a result, zkEVM Validium achieves significant improvements in scalability, potentially achieving thousands of transactions per second, similar to centralized payment systems.

2. Low transaction costs

High gas fees have been a persistent problem on the Ethereum network. As transaction volumes increase, the cost of executing simple transactions can also rise substantially, undermining the efficiency and usability of decentralized applications.

Polygon zkEVM Validium effectively alleviates this problem by reducing the number of calculations on the chain, thereby greatly reducing Gas costs.

On Polygon zkEVM, the cost of proving a 10 million gas batch is only $0.0259, or $0.00005 per transfer.

**By transferring most of the calculations to the Validium chain, users can experience lower transaction costs and more affordable dApp interactions. **This cost-effectiveness makes zkEVM Validium an attractive solution for decentralized finance (DeFi) protocols, non-fungible token (NFT) marketplaces, and other blockchain-based apps that rely on frequent and affordable transactions.

3. Enhanced privacy and security

**Privacy is a fundamental concern in the blockchain space. While traditional public blockchains offer pseudonymity, they lack strong privacy protections for sensitive data and transaction details. **zkEVM Validium utilizes Ethereum and zero-knowledge proofs to significantly enhance privacy.

In zkEVM Validium, users can submit transactions to the Validium chain in a privacy-preserving manner. Zero-knowledge proofs verify the validity of transactions without revealing the underlying data, ensuring the confidentiality of sensitive information. This enhanced layer of privacy also helps prevent front-running attacks, where malicious actors use trade order information to gain an unfair advantage.

4. Interoperability with Ethereum

One of the most compelling advantages of zkEVM Validium is its compatibility with the Ethereum ecosystem. Existing Ethereum smart contracts can be seamlessly deployed on the Validium chain without modification. This interoperability allows developers to take advantage of the vast library of Ethereum-based applications and tools, thereby simplifying the adoption process.

In addition, zkEVM Validium inherits the strong security features of Ethereum, benefiting from a proven consensus mechanism and a large network of miners protecting the main chain. This compatibility ensures that zkEVM Validium can maintain the same level of trustlessness and security as Ethereum, while providing significant scalability and privacy improvements.

5 Conclusion

The strengths of zkEVM Validium offer a promising solution to two of the most pressing challenges facing the blockchain industry: scalability, fees, and privacy. By utilizing zero-knowledge proofs to process transactions off-chain and verify transactions on-chain, zkEVM Validium achieves significant scalability enhancements and significantly reduces transaction costs.

Additionally, enhanced privacy features not only protect sensitive data, but also contribute to a safer and stronger blockchain ecosystem. With seamless interoperability with Ethereum, zkEVM Validium opens up a world of possibilities for decentralized application and smart contract development.

As the blockchain space continues to evolve, zkEVM Validium is at the forefront of innovative technologies, paving the way for mass adoption and unlocking the full potential of DeFi, dApps, and more. It represents a transformative step towards a more scalable, private and secure future for blockchain technology.
