Ethereum, a titan in the realm of blockchain, has been tirelessly striving to enhance network performance and reduce transaction costs in recent years. Amidst this ongoing pursuit, the upcoming Cancun upgrade has captured significant attention. The Cancun upgrade is poised to be a pivotal moment for Ethereum, ushering in a new era of Layer 2 technology.

Core of the Cancun Upgrade

At the heart of the Cancun upgrade lies the implementation of EIP-4844, also known as “proto-danksharding.” This proposal introduces a new transaction type called “blob,” expanding the blockchain’s data capabilities for improved scalability. Previously, Layer 2 periodically stored data on the Layer 1 main chain, distributing costs to users who transacted on Layer 2 during that period to reduce fees.

However, with the Cancun upgrade, Layer 2 transactions will be stored in a “blob.” This “blob” resembles Ethereum’s “external storage space.” Compared to the previous storage approach on L1, blob storage costs less and offers more space, significantly reducing the cost of each L2 transaction. This transformation heralds revolutionary changes for Ethereum’s Layer 2, achieving cost reduction and speed enhancement.

Impact of the Cancun Upgrade

The implications of the Cancun upgrade will manifest in several aspects:

Faster Transaction Speeds and Throughput: Transactions on Layer 2 utilizing Optimistic Rollup technology will drastically boost transaction speeds and throughput without compromising security. This addresses Ethereum’s network congestion and enhances efficiency for applications like DeFi and NFTs.

Lower Transaction Costs: As Ethereum’s transaction volume surges, escalating transaction fees have become a focal concern for users. The Cancun upgrade will substantially decrease Layer 2 transaction fees, making Ethereum’s Layer 2 network more accessible.

Enhanced User Experience: Faster transaction speeds and lower fees will significantly improve user experiences in fields such as DeFi and NFTs, driving wider adoption of blockchain technology.

Diverse Application Scenarios: The Cancun upgrade will introduce a plethora of Layer 2 application scenarios for Ethereum’s ecosystem. Increased speed and reduced costs will attract more developers and users, further expanding Ethereum’s ecosystem.
