🚀 Finally! The long-awaited Dencun upgrade arrived on Ethereum mainnet Wednesday morning around 9:55 am ET. Here's what you need to know:

- The core of Dencun is EIP 4844, aka "proto-danksharding" which improves blockchain scalability by expanding the data capacity of "blobs"

- It is hoped that layer 2 rollup costs will decrease

- Dencun includes 9 Ethereum Improvement Proposals (EIPs), making it the largest hard fork in terms of improvements implemented

- Layer-2 solutions like Arbitrum, Optimism, & Polygon will benefit the most from Dencun

With Dencun, this Layer-2 solution will be able to send data to Ethereum in a special "blobspace", eliminating the need for additional costs to enter data into standard transactions. This allows Layer-2 solutions to handle more data effectively & reduce transaction costs for end users. 🎉

Come on, discuss in the comments column! What do you think about this Dencun upgrade?
