New Exploration of Ethereum Rollup Ecosystem: Based Rollup and UniFi Solutions

In the field of blockchain scalability, Rollup technology has been a highly regarded solution. It enhances the processing capacity and efficiency of the blockchain by handling and bundling a large number of transactions off-chain, and then submitting the results to the mainnet. With the development of the ecosystem, new Rollup solutions continue to emerge, among which Based Rollup and UniFi solutions have sparked widespread discussion in the industry.

Overview of Rollup Technology

The core idea of Rollup technology is "off-chain computation, on-chain verification." It processes a large number of transactions outside the main network, only submitting the final results to the main network, thereby significantly improving transaction processing speed and reducing costs. Currently, Optimistic Rollup and ZK Rollup are two mainstream implementation methods, each with its own advantages.

Innovation of Based Rollup

Based Rollup is an emerging Rollup solution, with its core innovation being the transfer of transaction sorting responsibility from L2 to L1. This design fully leverages the node resources of the Ethereum mainnet, avoiding the potential risks associated with centralized sorters. However, this solution also faces the challenge of longer transaction confirmation times, as it is constrained by the block time of the Ethereum mainnet.

UniFi: Optimization Solution for Based Rollup

To address the efficiency issues faced by Based Rollup, a team proposed the UniFi solution. This solution introduces a "pre-confirmation" mechanism, where Ethereum validators commit to Rollup transactions before block packaging. This design greatly improves transaction confirmation speed while maintaining the characteristics of decentralization.

The core components of the UniFi solution include:

1. Pre-confirmation mechanism: Transactions containing commitments are provided by Ethereum validators.
2. Penalty mechanism: Ensure that validators fulfill their commitments.
3. AVS (Application Verification Service): Based on re-staking technology, it provides support for the pre-confirmation mechanism.

Core Advantages of UniFi

The UniFi solution demonstrates several advantages in the Rollup ecosystem:

1. Decentralized Sorting Based on L1
2. Improve transaction confirmation speed through pre-confirmation technology
3. Create yield opportunities for re-staking
4. Achieve synchronous composability

It is especially worth mentioning that the sync composability of UniFi helps to address the current liquidity fragmentation issue in a multi-Rollup environment. It allows different Rollups to interact within the same block without relying on cross-chain bridges, thus providing users with a smoother experience.

Future Outlook of the Rollup Ecosystem

The emergence of the Based Rollup and UniFi solutions has brought new ideas to Ethereum's scalability technology. These solutions create an interesting contrast with existing technologies such as Optimistic Rollup:

• Based Rollup is more like the "elite troops" of the Ethereum mainnet, directly controlled by the mainnet, offering higher security and native synchronization compatibility.
• Traditional Rollups are more like "feudal lords", possessing greater autonomy, but may face more challenges in terms of security and cross-chain interactions.

In the future, these different Rollup solutions are likely to coexist and develop to accommodate various types of application scenarios. Developers will continuously weigh factors such as decentralization, efficiency, and benefit distribution, driving the advancement of blockchain technology.

The inclusiveness and innovative spirit of blockchain technology will continue to drive the exploration and development of various Rollup solutions. Only through continuous technological iteration and conceptual innovation can we create a better future for the blockchain ecosystem.
