Arbitrum (ARB)
Arbitrum is a prominent Ethereum scaling solution designed to deliver cost-effective transactions to a vast number of users while maintaining an experience akin to the Ethereum network. As an optimistic rollup, Arbitrum is recognized as the leading Layer 2 (L2) solution, particularly in terms of total value locked (TVL). Its ecosystem supports some of the most significant decentralized applications (dApps), including GMX, Radiant, Uniswap V3, and Gains Network.
The technology behind Arbitrum
Optimistic rollup explained
Optimistic rollups are a type of layer 2 scaling solution that aims to enhance the throughput and reduce the transaction costs of Ethereum. They achieve this by processing transactions off-chain, which are later batched and posted on-chain. The term "optimistic" refers to the assumption that transactions are valid by default. Only in cases of disputes or fraud do validators need to provide proof. This approach significantly reduces the computational load on the Ethereum mainnet, allowing for faster and cheaper transactions.

Arbitrum's architecture
Arbitrum's architecture leverages the optimistic rollup technology to enable scalability. Its off-chain processing capability allows for the aggregation of multiple transactions before they are submitted to the Ethereum mainnet. This method ensures that the mainnet is only used for settling disputes and finalizing batched transactions, which conserves bandwidth and reduces congestion. The security model relies on Ethereum's robust consensus mechanism, ensuring that Arbitrum inherits the security features of the main Ethereum blockchain.
Key features of Arbitrum
Cost-effectiveness
One of the primary advantages of Arbitrum is its ability to significantly reduce transaction costs. By processing transactions off-chain and only using the Ethereum network for finalization, users experience lower gas fees compared to executing the same transactions directly on Ethereum.
High throughput
Arbitrum's design allows for a substantial increase in transaction throughput. By offloading the computational work from the Ethereum mainnet, Arbitrum can handle thousands of transactions per second, making it a highly efficient solution for dApps that require high transaction volumes.
Compatibility with Ethereum
Arbitrum maintains compatibility with Ethereum, enabling developers to deploy their Ethereum dApps on Arbitrum with minimal changes. This compatibility ensures that developers can leverage existing Ethereum tooling and infrastructure, facilitating a seamless transition to this layer 2 solution.
Arbitrum's ecosystem
Major dApps on Arbitrum
Arbitrum hosts a variety of prominent decentralized applications that benefit from its scalability and cost advantages. Some of the notable dApps include:
- GMX: A decentralized exchange and perpetual contract trading platform that capitalizes on Arbitrum's low fees and high speed.
- Radiant: A lending and borrowing platform that provides users with efficient financial services within the Arbitrum ecosystem.
- Uniswap V3: The popular decentralized exchange, Uniswap, has extended its services to Arbitrum, offering users a familiar trading experience with reduced transaction costs.
- Gains Network: A decentralized finance platform that leverages Arbitrum's capabilities to offer innovative financial products and services.
Total value locked (TVL)
Arbitrum has achieved the status of the leading L2 solution in terms of total value locked (TVL). This metric indicates the overall value of assets deposited in the various dApps operating on Arbitrum. The high TVL reflects user confidence in Arbitrum's security and efficiency as a scaling solution.
