The Dencun upgrade, a significant advancement in [[Ethereum]]'s evolution, focuses on enhancing the network's scalability and efficiency. Its core feature, known as proto-danksharding ([[Ethereum Improvement Proposal (EIP)]]-4844), introduces a new method for storing data, specifically targeting "blobs" of information that are temporary and don't need to be permanently stored on the blockchain. This is particularly beneficial for [[Layer-2]] scaling solutions like rollups, which can now process larger amounts of data off-chain at a lower cost. By optimizing data handling and reducing fees for these Layer-2 solutions, Dencun paves the way for increased transaction throughput and a smoother user experience on the Ethereum network. It's an important step towards full danksharding, which promises even greater scalability improvements in the future.
