Scalability is a key advantage of both Arbitrum and zkSync, as they seek to alleviate the congestion on the Ethereum network. Arbitrum’s Optimistic Rollup can process thousands of transactions per second by aggregating them into batches and using an efficient off-chain processing model. This significantly increases the throughput compared to Ethereum’s main chain, making Arbitrum a viable solution for high-demand applications such as DeFi and gaming. zkSync’s zk-Rollup also offers high scalability by batching transactions and validating them with zero-knowledge proofs. zkSync can achieve similar or even higher throughput levels, as the validity proofs ensure that only the minimal necessary data is posted on-chain. This allows zkSync to handle a large volume of transactions with low latency. Both platforms provide substantial scalability improvements, but zkSync’s zk-Rollup technology may offer a slight edge in terms of maximum throughput due to the efficiency of its zero-knowledge proof system, making it particularly suitable for applications requi
