Ethereum's Dencun Upgrade Approaches: Layer2 Ecosystem Heats Up – Project Progress and Market Expectations

Dencun Upgrade on the Horizon: Ethereum Layer2 Ecosystem Gets a Key Catalyst

The Ethereum community is closely focused on the upcoming Dencun upgrade (Cancun-Deneb). Its core component, EIP-4844 (Proto-Danksharding), is widely seen as a milestone for Layer2 scaling solutions. By introducing a new temporary data storage space called "Blobs," Dencun is expected to significantly reduce the cost for Layer2s to submit transaction data to Ethereum's mainnet, directly lowering fees and boosting throughput on Layer2 networks. Market consensus suggests this technological shift will accelerate the maturation and explosion of the Layer2 ecosystem.

Layer2 Heat Surges: From Tech Narrative to Real-World Use

As the upgrade date nears, the Layer2 sector has become one of the most closely watched areas in the crypto market. According to L2BEAT data, the total value locked (TVL) across Ethereum Layer2s has hit an all-time high, signaling a rapid influx of capital and users. Popular projects such as Arbitrum, Optimism, Base, zkSync Era, and StarkNet are all showing signs of significantly increased activity. Market analysts believe Dencun will solve the long-standing "data availability" bottleneck for Layer2s, enabling these networks to process more transactions at lower costs, thereby unlocking greater potential in applications like DeFi, gaming, and social media.

Key Layer2 Project Progress Overview

• Arbitrum: As the leading Optimistic Rollup by TVL, Arbitrum recently launched the Orbit tech stack, allowing developers to build custom Layer3 chains. The community is closely watching how it leverages Dencun to further reduce cross-chain costs.
• Optimism: The OP Stack ecosystem continues to expand, with Base (Coinbase's Layer2) already live on the stack and rapidly accumulating users. The Optimism team states that Dencun could reduce their network's transaction fees to near zero.
• zkSync Era: As a leading ZK Rollup, zkSync Era has completed several performance optimizations ahead of the upgrade. Expectations around the governance and airdrop of its native token, ZK, have also attracted significant attention.
• StarkNet: StarkNet recently launched StarkEx and Appchain solutions, and plans to further optimize the execution efficiency of its Cairo programming language after Dencun.
• Base: Backed by Coinbase, Base has leveraged its massive user base to climb the TVL rankings within just a few months. Its "Onchain Summer" campaign drove a wave of NFT and social app migrations to Layer2.

Market Expectations and Potential Impact

According to multiple industry analyses, the Dencun upgrade could become one of the most important narratives for the Ethereum ecosystem in 2024. If implemented smoothly, transaction fees on Layer2 networks are expected to drop by 80-90%, directly benefiting cost-sensitive areas like high-frequency trading, micropayments, and gaming. Additionally, lower fees could attract more traditional Web2 users into the crypto world. However, some caution that the market may have already partially priced in the upgrade's benefits, warning of potential "buy the rumor, sell the news" volatility.

From a broader perspective, Dencun is a critical step in Ethereum's "rollup-centric" roadmap. It marks a clearer division of labor between Layer1 and Layer2: the mainnet focuses on security and decentralization, while Layer2s handle large-scale applications. If successful, this architecture will solidify Ethereum's leading position in smart contract platforms and could spark a new wave of Layer2 application innovation.
