The price of Optimism (OP) has been skyrocketing since the beginning of July due to its proximity to Ethereum.

"Currently, with the combined rollup and Ethereum architecture, the current Ethereum-only transaction throughput of 15–45 TPS could scale to as much as 1,000–4,000 TPS," noted Ally Zach, a researcher at Messari, adding:
