Arbitrum ARB

Arbitrum is a suite of scaling solutions for Ethereum. It provides high-throughput, low-cost smart contracts and is backed by industry-leading proving technology. It aims to enhance the scalability of Ethereum and allows for faster transaction processing. Arbitrum transactions are posted on the Ethereum blockchain, ensuring data availability and transaction finality.

Arbitrum is unique compared to other cryptocurrencies due to its focus on secure scaling for Ethereum. It offers high-throughput, low-cost smart contracts backed by industry-leading proving technology rooted in Ethereum. One of its key features is the use of rollups, which enable transaction execution to be moved off-chain while transaction data is still posted on the Ethereum blockchain. This allows for faster and more efficient processing of transactions. Additionally, Arbitrum employs a fraud-proof mechanism, where validators can challenge assertions and receive rewards for proving fraud. This ensures the integrity and correctness of transaction execution. Overall, Arbitrum's approach to scaling and security sets it apart from other cryptocurrencies.
