Polygon PoS proposes a major upgrade to a zkEVM validium, addressing challenges and improving its value proposition. 

The upgrade leverages the security of Ethereum and Polygon’s zkEVM technology. Validiums offer lower fees and higher scalability compared to rollups. The upgrade brings increased security, a future-proof tech stack, reorg elimination, faster transaction confirmations, increased scalability, improved fee estimation, greater decentralization, and compatibility with Polygon 2.0. 

The upgrade is viable, straightforward, and beneficial. It enhances the long-term relevance and reliability of Polygon PoS, making it a pivotal solution for the ecosystem.

The network aims to create a smart contract platform and will utilize Frax stablecoin and Frax Ether for transaction fees. Fraxchain’s governance will be led by Frax Shares (FXS) token holders. It incorporates a Layer 2 rollup model and decentralized sequencers, allowing for decentralized order sequencing. 

Unlike other Layer 2 solutions, Fraxchain enables the auctioning and rotation of sequencer roles, ensuring continuity in case of shutdowns. The network is expected to launch by year-end, offering enhanced scalability and security for the Frax ecosystem.

The Step-by-step Guide for The Potential Polygon zkEVM Airdrop

Pkncrehhx9Nqpkm30Pjt2Dlgt4Etrtssc3Oatszljybaas61Cl169Prw Y54Uvfx89Wval0Pxcvgglt9D Y3E9Qqcx4Par Buws1Mis3Y4Fnd3Krxfjtua28Mimizwmml5Msa8Xmu A1Bc37Wc3V9V4

Polygon zkEVM is a zk Rollup Layer solution that utilizes zkEVM technology developed by Polygon Labs, a unit specializing in developing Ethereum scaling solutions, with its most famous product being Polygon PoS.

On March 27, 2023, Polygon zkEVM officially launched the Mainnet Beta version, allowing users and developers in the market to use and build freely on this Layer 2. Applying zkEVM will provide a better product development experience for programmers.

From this, Ethereum DApps can easily migrate to the zk-Rollup chain without making significant changes to source code or spending effort and time to rebuild the product from scratch. Instead, they can focus on innovation and creative development models for their products.

On July 10th, the Polygon zkEVM token will be confirmed. Find a step-by-step tutorial for the potential airdrop here.
