The Ethereum blockchain, while revolutionary, faces significant scalability challenges due to its limited transaction capacity of 20-40 transactions per second (TPS). This congestion leads to high fees and delays during peak usage. Layer 2 (L2) networks like Arbitrum offer a proven solution by processing transactions off-chain, alleviating mainnet congestion. Arbitrum stands out as a leading L2 solution designed to tackle Ethereum's scalability issues while maintaining security and decentralization.
What is Arbitrum?
Arbitrum is a Layer 2 scaling solution for Ethereum that enhances transaction throughput and reduces fees. It operates as a sub-module within Ethereum, processing transactions off-chain to minimize congestion. Using optimistic rollups, Arbitrum bundles transactions off-chain and validates them on Ethereum's mainnet, combining efficiency with security.
Ethereum’s design prioritizes decentralization over scalability, limiting its transaction capacity. Arbitrum provides a seamless workaround, allowing users to enjoy Ethereum’s benefits—such as security and smart contract functionality—without its drawbacks.
How Arbitrum Works
Arbitrum leverages Optimistic Rollups and the Arbitrum Virtual Machine (AVM) to enhance Ethereum’s scalability.
Optimistic Rollups
Optimistic Rollups process transactions off-chain, assuming their validity unless disputed. Batches of hundreds of transactions are submitted to Ethereum as a single unit, significantly boosting throughput. Invalid transactions trigger penalties, ensuring network integrity.
Arbitrum Virtual Machine (AVM)
The AVM is fully compatible with the Ethereum Virtual Machine (EVM), enabling developers to migrate smart contracts effortlessly. This compatibility ensures high performance for decentralized applications (DApps) and DeFi projects. Governance is facilitated by the ARB token, which grants voting rights but isn’t used for transactions.
