What is Polygon zkEVM ?

Polygon zkEVM (Zero-Knowledge Ethereum Virtual Machine) is a layer 2 scaling solution that has been developed by Polygon (formerly known as Matic Network) to address the scalability challenges of the Ethereum blockchain. It offers a unique combination of high throughput, low transaction fees, and Ethereum compatibility, making it an attractive option for developers and users alike.

One of the key features of Polygon zkEVM is its ability to provide zero-knowledge proofs (ZKPs) for transactions, which allows for increased privacy and security. ZKPs are cryptographic proofs that enable the verification of a statement without revealing any additional information beyond the fact that the statement is true. This means that transactions can be verified without revealing the sender, receiver, or amount involved.

Another important feature is its compatibility with the Ethereum Virtual Machine (EVM). This means that all existing smart contracts, developer tools, and wallets that work on the Ethereum blockchain can seamlessly transition to Polygon zkEVM without any modifications. This makes it easy for developers to migrate their existing Ethereum-based applications to Polygon zkEVM, and leverage the benefits of its high throughput and low transaction fees.

Polygon zkEVM achieves high throughput by using a Proof of Stake (PoS) consensus mechanism, which allows for faster and cheaper transaction processing compared to Proof of Work (PoW) used by Ethereum. This means that Polygon zkEVM can handle a significantly higher number of transactions per second, while keeping transaction fees low. In addition, Polygon zkEVM offers fast finality, which means that transactions are confirmed quickly and efficiently.

‍

Security

• Ethereum security inherited in L2 with the additional benefit of L2 batching for scaling
• ZK proofs ensure transaction validity and safeguards user funds
• Assurance that information stored cannot be changed or corrupted

‍

Overall, Polygon zkEVM is a leading zero-knowledge scaling solution that offers Ethereum compatibility, high throughput, and low transaction fees. Its unique combination of features makes it an attractive option for developers and users who are looking to build and use decentralized applications that require fast and secure transaction processing. With the continued growth of the blockchain ecosystem, it is expected that Polygon zkEVM will play an increasingly important role in driving innovation and adoption of blockchain technology.
