Ethereum's Upcoming Rollups Promise 100-Fold Scalability Boost
Written on
Chapter 1: The Current State of Ethereum
Ethereum stands as the leading blockchain for smart contracts globally, particularly dominating the DeFi sector. This prominence is attracting a growing pool of investors. Recently, the price of ETH surged past $2,000, achieving a new all-time high. However, this position is being challenged by rival platforms like Cardano and Polkadot, mainly due to Ethereum's ongoing scalability issues, which result in soaring transaction fees.
In times of high demand, simple transactions can incur fees of up to $30, while those involving smart contracts often exceed $50. Although the introduction of sharding with Ethereum 2.0 is expected to remedy these issues, users are eager for immediate solutions. Consequently, various initiatives are actively developing Layer 2 solutions to enhance scalability rapidly. One of the most promising approaches involves using rollups.
Scaling Solutions: The Role of Rollups
Rollups consolidate multiple sidechain transactions into a single entry, creating a cryptographic proof (SNARK = succinct non-interactive argument of knowledge) that integrates with the Ethereum mainchain. This method allows transactions to be processed on sidechains, while the mainchain merely records the transaction data. As a result, transaction costs can be substantially reduced, and processing capacity can be significantly increased.
Ethereum's co-founder, Vitalik Buterin, expresses strong confidence that rollups will address the scalability challenge in the near term. In a podcast with Tim Ferris on March 9, 2021, he indicated that rollups could lead to a scaling factor of 100, allowing the blockchain to handle between 1,000 and 4,000 transactions per second, depending on transaction complexity. He also mentioned that Optimism’s fully EVM-compatible rollup is projected to launch within a month.
Optimism Rollups: Tailored for DeFi Applications
Several DeFi projects are exploring the potential of Optimism’s rollup solution, with MakerDAO actively engaged in this effort. The MakerDAO community has unveiled the Optimism Dai Bridge, which addresses the week-long withdrawal delay typically associated with optimistic rollups.
Here’s how it operates:

Chapter 2: The Future with Ethereum 2.0
Sharding represents the strategy for achieving scalability in Ethereum 2.0. By dividing Ethereum’s infrastructure into smaller segments, its capacity can be enhanced.
The significant advantage of rollups is their compatibility with Ethereum 2.0. The combination of sharding and rollups could lead to even greater scalability. Vitalik Buterin envisions potential scaling of up to 10,000 times, predicting the ability to process over 100,000 transactions per second. He notes that as computer efficiency improves, more shards can be supported, effectively quadrupling the system's capacity.
Conclusion: A Bright Future for Ethereum Scaling
The encouraging developments regarding Ethereum’s scalability come at a critical moment, as complaints about high fees have surged recently. Although uncertainties remain about the execution of these plans, if the anticipated 100-fold scaling materializes in the coming months, it could elevate Ethereum's status and leave its competitors trailing behind.
