Answer: Incentive to run a rollup is a need to host your dapp, but it is also important to consider the benefits of a general purpose rollup. A general purpose rollup allows users to deploy EVM smart contracts on a secure, cost-effective platform that is powered by a consensus mechanism. This allows for faster and more secure transactions, as well as lower transaction fees. Furthermore, a general purpose rollup is more accessible to developers, as it is easier to deploy and manage. This opens up a much wider range of possibilities for developers, allowing them to create and deploy more complex applications. Ultimately, a general purpose rollup provides a more secure, efficient, and cost-effective platform for hosting dapps.
