# Classical When we talk about classical miners, we mean our bread and butter compute platforms that don't support entanglement: CPUs, GPUs, TPUs, NPUs, and the like. While the network often leads with quantum computing as a differentiator, these traditional compute architectures are a first class citizen of the Quip Network that help to validate the quantum computers are really delivering improved performance. #### Node Requirements Node requirements are minimal. There is no barrier to entry for running a node, but you will have to fit the blockchain on local storage and your block rewards will be correlated with your ability to efficiently solve the Proofs of Useful Work supported by the network. The first Proof of Useful Work is finding the ground state energy of a Hamiltonian, often called an Ising Model problem. These solutions can be used in a variety of optimization and constraint programming problems, providing useful outputs for real businesses. The network currently publishes Metal and CUDA solvers as well as direct implementations for x86 and ARM CPUs. If you have another framework or instruction set you would like to support, please submit an issue at our [Github](https://github.com/quipnetwork). #### Run a Node Please see the [Run a Node](/docs/nodes/run-a-node-testnet.md) section. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://quip.gitbook.io/docs/nodes/classical.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
