The 'Atlas' upgrade, also known as Dencun, introduced a new transaction model called blobs to Ethereum, aiming to reduce fees for Layer 2 networks.

Proto-danksharding, a feature of the upgrade, processes data in smaller segments to expedite transactions and lower operational costs for L2s like Optimism, Zora, and Base.

The implementation of blobs is more cost-effective compared to previous data storage methods, contributing to significantly lower transaction fees.

Following the upgrade, there was a temporary 2.44% decrease in Ether's (ETH) price, but it subsequently stabilized to its pre-upgrade value.

Ethereum's Layer 2 network Starknet observed a 90% reduction in gas fees post-upgrade, indicating substantial cost savings for users.

Investors are advised to do their due diligence before making investment decisions in light of these changes.

The Atlas upgrade is generally viewed as a beneficial development for the Ethereum ecosystem, enhancing scalability and reducing Layer 2 transaction costs.
