What is Arbitrum?
Arbitrum is a Layer2 expansion solution with the core goal of improving the performance and scalability of Ethereum networks. ArbitrumRollup uses a technology called Optimistic Rollup, which takes on the burden of the Ethereum network by migrating smart contracts and transactions on the second layer chain.
On ArbitrumRollup, users can execute smart contracts and transactions on Ethereum, but the processing speed is faster and transaction costs are expensive. This is achieved by conducting transactions on the ArbitrumRollup chain and then submitting the results to the Ethereum main chain. The main smart contracts and data are stored on the Ethereum main chain, ensuring security and decentralization.
The goal of Arbitrum is to solve the congestion problem of Ethereum networks and provide faster, more efficient, and cost-effective transaction processing. It allows developers to build centralized applications based on Layer2 while providing users with a better user experience.
The problem of limited scalability of Ethereum
The main issue with Ethereum's limited scalability stems from its design decisions, especially the adoption of a full node consensus approach, which requires all nodes to verify and record each transaction, resulting in limited transaction processing speed.
In order to address the scalability issue of Ethereum, the Ethereum community has proposed various solutions, one of which is the Layer2 expansion solution, such as Arbitrum. These solutions improve transaction throughput and reduce transaction costs by building a second layer network outside the Ethereum main chain, transferring the execution of transactions and smart contracts to the side chain or optimistic aggregation protocol, while still maintaining the security of the Ethereum main chain.
In addition, Ethereum upgrade, the transition from Ethereum 1.0 to Ethereum 2.0, introduces higher performance and scalability. Ethereum 2.0 adopts the consensus mechanism of PoS (Proof of Rights) instead of PoW (Proof of Work), which leads to increased throughput, reduced energy consumption, and improved network security.
In summary, the scalability issue of Ethereum is a complex challenge, but through the Layer2 solution and the upgrade of Ethereum 2.0, the Ethereum community is actively working to address this issue, providing a better user experience and responding to the urgent growing demand for problems.
How does ArbitrumRollup solve this problem
ArbitrumRollup is an optimistic aggregation protocol that is seen as a key solution for improving Ethereum scalability. Unlike the first layer (Layer1, L1) of Ethereum, Arbitrum is a second layer (Layer2, L2) solution built outside the Ethereum main chain to improve transaction throughput and reduce transaction costs while maintaining interoperability with the Ethereum main chain.
The working principle of ArbitrumRollup is to migrate the execution of transactions and smart contracts from the Ethernet main chain to the Arbitrum chain, and then regularly submit the summary results of these transactions to the Ethernet main chain. This means that Arbitrum does not require Ethereum nodes to handle arbitrage transactions, significantly improving transaction throughput and reducing costs. At the same time, it maintains the security and interoperability between transactions and the Ethereum main chain.
Arbitration risk adopts an optimistic approach, assuming that the activities in arbitration follow appropriate rules, rather than immediately verifying each transaction on the Ethereum main chain. This makes trading faster, but it may also exist, such as prevention. However, arbitration provides a method of resolving disputes at the first level of Ethereum. If there is a dispute, a ruling can be made on the Ethereum main chain and fraudulent defamation can be proven, thereby punishing the malicious party.
Overall, ArbitrumRollup is an Ethereum scalability solution that improves user experience by increasing transaction throughput and reducing costs, while inheriting the security of the Ethereum main chain.
The transparency and fraud prevention process of ArbitrumRollup are key features of this technology, aimed at ensuring security and user trust.
- Transparency: The design requirement of ArbitrumRollup is mainly to publish data on the Ethereum blockchain, including user transaction data. This means that anyone interested in blockchain can monitor the activity of the ArbitrumRollup chain, view transactions, and verify their openness, which helps ensure the system's openness and detection of suspicious activities.
- Fraud prevention process: ArbitrumRollup introduces an optimistic aggregation method where participants in the voting system adhere to rules, thereby improving transaction speed. However, if disputes or fraud arise, there is a process in place to resolve the issue. On the first level of Ethereum, disputes can be adjudicated, and there is also a mechanism to prove fraudulent allegations. This means that users do not need to rely on trusting any single party, as there are methods in the system to protect their funds.
- Role: The validator in ArbitrumRollup plays a key role in supporting the chain's operation.
In fact, Arbitrum represents an innovative solution aimed at improving the scalability and user experience of Ethereum. It adopts an optimistic aggregation protocol that allows transactions to be processed outside the chain, thereby improving transaction throughput and reducing user costs, while maintaining compatibility and security with Ethereum. It can help Ethernet better solve the problems of congestion and high fees in transactions, providing users with a faster and more economical trading experience.
The emergence of Arbitrum also reflects the continuous innovation and development within the Ethereum ecosystem. It not only demonstrates the flexibility of Ethereum as a blockchain platform, but also demonstrates the community's efforts to improve network performance and user friendliness. These technological advancements will facilitate the large-scale popularization of cryptocurrencies and decentralized applications, thereby driving the development of the entire blockchain industry.
