Polygon Labs developer sees great benefits for the zkEVM and the Ethereum network through the Dencun upgrade
Polygon Labs Developer Relations Engineer, Jarrod Watts, expressed belief in a March 12 post that Ethereum's long-awaited Dencun upgrade will provide major benefits for the Polygon zkEVM and the broader zero-knowledge Ethereum Virtual Machine (zkEVM) ecosystem.
The upcoming Dencun upgrade is intended to improve Layer 2 solutions that leverage rollup technology, such as Optimism and Arbitrum.
Of particular importance is the implementation of EIP-4844, which introduces “blobs” – efficient storage channels – to further reduce Layer 2 transaction costs.
Polygon is compatible with the Ethereum Virtual Machine (EVM), but it operates as a sidechain instead of a true Layer 2 rollup solution. Therefore, the impact of the Dencun upgrade on Polygon is likely to be less pronounced.
Polygon zkEVM, on the other hand, uses both zero-knowledge proofs (for improved privacy) and rollups. This means it can potentially benefit from the Dencun upgrade.
Watts, an engineer working on the project, notes that about 80% of zkEVM fees come from call data. By moving to more efficient “blob” storage following the Dencun upgrade, Polygon zkEVM aims to dramatically reduce these fees.
Ethereum’s Dencun upgrade will bring benefits to various Layer 2 platforms. These platforms will be able to offer their users lower transaction fees and higher throughput performance.
Polygon zkEVM plans to integrate EIP-4844 proposals, with testing starting on the testnet in April. The Feijoa upgrade will bring these changes to mainnet about a month later.
At the same time, Polygon is also working on Polygon 2.0. A core part of this upgrade will be the conversion of their current native token, MATIC, to POL.
This token exchange is intended to unify the entire Polygon ecosystem and serve as a medium of exchange and governance.
