Flux and Proof of Useful Work
At Mining Disrupt Miami 2023, Daniel Keller pitched Flux, a GPU-mined network that switches miners from hashing to paid compute jobs.
Daniel Keller told a room of Bitcoin miners he would not be talking about mining rigs, immersion or Bitcoin. He had come to talk about Flux and what he called proof of useful work. Keller spoke at Mining Disrupt Miami 2023, held July 25 through 27, 2023. That was 1,175 days ago.
Bitcoin traded at $29,125 then. On October 12, 2026 it was $83,900. His question was how to get more computing power to the people and projects that need it. His answer was a network of GPU miners who can switch to paid compute jobs.
In his words, Flux is the very first and largest decentralized compute network that you've never heard of, and that's by design. The team, he said, wanted it fully working before it was promoted. Flux hosts applications, websites and cloud services on a node network of its own. Keller put it at more than 13,000 nodes in just about every country, and said the team was preparing to deploy more than a hundred thousand more on mining rigs.
He called it AWS on the blockchain. The network stays GPU-only by rule. Keller said Flux is ASIC resistant and would immediately fork the project if ASICs or FPGAs were ever detected. Older cards such as a 1070 Ti or 1060 Ti can still take part.
He called the approach run till death, and tied it to a carbon-neutral goal. Here is how the switch works. A rig mining Flux, or another proof-of-work coin, can be moved to useful work when a job arrives, such as AI work, rendering or edge compute. Pricing depends on the task configuration, the reward quantity and reward upon completion.
A data center can also wait on standby for jobs. Storage runs through Flux Drive, which he described as a decentralized Dropbox, sharded over IPFS, with no third party between you and your data. The hardware bar is ordinary. A CPU and motherboard that support virtualization, PCIe Gen 3.0, a CPU with four threads, and minimum RAM and video memory.
Keller said these are the machines people already run at home, especially gamers, and that this opens the next version of proof of work to anyone who wants it. Operators get a dashboard to configure and benchmark workers and split them across tasks, and they can keep mining another coin while they wait. He closed with a motto. Google once said don't be evil.
Flux, Keller said, says don't be evil again. The full story is on Intelligence Disrupt at intelligencedisrupt dot com, and many more like it play around the clock on Bitcoin Radio.
