Ethereum Prepares for Dencun Upgrade: What You Need to Know

By

What Is the Dencun Upgrade?

The Dencun upgrade is Ethereum’s most important technical upgrade since the Shanghai hard fork. It combines two proposals — Deneb (consensus layer) and Cancun (execution layer) — aimed at significantly improving Ethereum’s scalability, efficiency, and Layer 2 ecosystem.

Set to go live in July 2025, Dencun will introduce a critical feature called proto-danksharding, which is expected to drastically reduce transaction costs on Layer 2 networks like Arbitrum, Optimism, and Base.

What Is Proto-Danksharding?

Proto-danksharding (aka EIP-4844) is a stepping stone toward full sharding, which has long been part of Ethereum’s roadmap. Rather than breaking the blockchain into shards immediately, this upgrade introduces “blobs” — new data structures that allow Layer 2 rollups to post data more efficiently on Ethereum.

✅ Benefits of Proto-Danksharding:

  • 🔹 Lower gas fees for Layer 2 transactions
  • 🔹 Increased throughput and scalability
  • 🔹 Faster and more cost-effective DeFi and NFT activity
  • 🔹 Stronger developer support for rollup-based solutions

Why Does the Dencun Upgrade Matter?

Ethereum has struggled with high gas fees and network congestion, especially during times of increased market activity. The Dencun upgrade is Ethereum’s answer to scaling without sacrificing decentralization or security.

This makes Ethereum:

  • ⚡ More efficient for developers
  • 💸 Cheaper for users
  • 🧱 Stronger as a base layer for Web3 applications

At Coincashyangel.com, we expect this upgrade to further encourage users to adopt ETH for trading, sending, and building applications — especially with simplified ways to buy Ethereum using Visa, MasterCard, PayPal, and other everyday payment options.

Impact on Layer 2 Networks

Layer 2 networks like Optimism, Arbitrum, Base, and zkSync will see the biggest benefits. These platforms depend on Ethereum’s mainnet for security but operate off-chain for speed and cost-efficiency.

With proto-danksharding:

  • Layer 2 fees could drop by up to 10x
  • Developers can build more scalable dApps
  • Ethereum becomes a serious contender for mass adoption and microtransactions
