Ethereum, as a pioneer in blockchain technology, faces growing user demand and complex application scenarios. In this context, the rise of Layer 2 expansion solutions and one-click multi-chain technology have become key factors in promoting the performance and ecological development of the Ethereum network.
1. Connecting island chains: Challenges of cross-chain asset transfer
In the blockchain ecosystem, the architecture and consensus mechanisms of each blockchain vary, making cross-chain asset transfers complex and costly. Existing third-party bridging solutions face challenges in trust and security, while centralized bridging needs to maintain liquidity and pass on costs to users. In this context, one-click chain technology, as a compromise solution for asset bridging, shows its unique potential.
2. Layer 2 Scaling Solutions
2.1 Rollups: Improving transaction speed and reducing costs
Rollups is one of the core technologies for Layer 2 expansion, including Optimistic Rollups and zk-Rollups. They aggregate a large number of transactions to off-chain processing and submit the final results to the Ethereum main chain, effectively reducing the transaction burden on the main chain and improving the throughput and efficiency of the network. Optimistic Rollups assumes that all transactions are valid and only verifies them when errors are found, while zk-Rollups use zero-knowledge proof technology for batch processing to ensure the validity of transactions.
2.2 State Channels: Accelerating Micropayments
State Channels allow transactions to be conducted off-chain, ultimately committing state changes to the main chain. This method is particularly suitable for frequent micropayments and micropayment scenarios, and can significantly improve transaction speed and efficiency.
3. The rise of one-click multi-chain technology
3.1 Elastic Chain: A new solution for ZKsync
Elastic Chain is an extension solution launched by ZKsync, which realizes native, trustless, and low-cost interoperability between chains through the ZK Stack framework. It consists of ZK Router, ZK Gateway, and ZK Chains, and realizes seamless cross-chain operations and transaction aggregation. The design goal of Elastic Chain is to improve interoperability within the ZKsync ecosystem and ensure the security and efficiency of transactions.
3.2 AggLayer: Innovation of Polygon 2.0
AggLayer is a core component of Polygon 2.0, which enables interoperability with other blockchains through unified bridging and security services. AggLayer adopts a shared validity sorting design to achieve atomic cross-chain interoperability between multiple Rollups. Unified Bridge and Pessimistic Proofs are its core components. The former realizes cross-chain communication and liquidity aggregation, and the latter provides additional transaction verification steps to ensure the security of transactions.
3.3 Superchain: Pioneer of Optimism
Optimism Superchain provides a unified development stack and protocol through OP Stack, achieving Ethereum expansion and multi-chain interoperability. Superchain's design includes data availability layer, sorting layer, derivation layer, execution layer and settlement layer, each layer has different functions, ensuring that each chain can operate in coordination as a whole. Base is a successful example based on Superchain, demonstrating its efficient on-chain activity and a wide range of application scenarios.
4. 行业趋势和未来展望
4.1 Competition in Layer 2 Scaling Technology
From the perspective of market maturity, OP Stack and Superchain have taken the lead in occupying the market, showing strong market share and application potential. AggLayer has an advantage in compatibility and can be directly integrated into the existing Ethereum network, while the success of Elastic Chain depends on the ecological development and community building of ZKsync. In the short term, OP and AggLayer will become the focus, while in the long term, more attention may be paid to the progress of ZKsync and Elastic Chain.
4.2 Future Applications of Rollups
In the context of limited industry innovation, DeFi remains the main application scenario for Rollups. Although DePIN, RWA, and large GameFi projects are less likely to be on Rollups, SocialFi and NFT markets may appear. However, the market heat is still uncertain, and the blockchain as a whole presents a Matthew effect. The application trend of Rollups deserves long-term attention.
Summarize
The evolution of Ethereum, especially the combination of Layer 2 expansion and one-click multi-chain technology, marks the progress of blockchain technology towards higher performance and wider interoperability. Through the application of these technologies, Ethereum not only improves network performance, but also promotes the prosperity of the blockchain ecosystem. In the future, the development of these technologies will continue to lead the innovation trend of digital assets and decentralized applications, bringing unlimited possibilities to the blockchain ecosystem.
