This is a fork of the original dPow to make it easier to install and run on windows
- Download and install Python v3.7.3 from python.org
- Open a command prompt and navigate to /nano-dpow/client
- type: pip3 install --user -r requirements.txt
- run the file run_windows.bat
- Pip3.exe not found If you get this error when running the pip3 command you may need to specify the absolute path to pip3.exe.
You can do this by searching your c drive for 'pip3.exe' and inserting the path.
Example:
C:\Users\username\AppData\Local\Programs\Python\Python37\Scripts\pip3 install --user -r requirements.txt
- 'python.exe is not recognized as an internal or external command'
Same thing as above. You have to edit run_windows.bat and change python.exe to the absolute path

Welcome to the Distributed Proof of Work (DPoW) system. The DPoW system allows any user to support Nano community services by computing the required proof of work for transactions.
DPoW has helped reduce operating costs of community projects, such as faucets, tipping bots, and wallets. As a reward for helping, clients get occasional Nano payouts.
In the Nano protocol, every block must contain a small proof of work to be confirmed by the network. While a desktop with a modern graphics card can easily and quickly compute this proof, the process can require significant resources from a server and mobile devices. Services often need to scale quickly when there is an uptick in usage, and on-demand scalable solutions based on GPUs are not available given the time-to-deploy requirements.
DPoW provides a hub between services and clients who are happy to provide their resources, in return for small payouts. Consequently, services save significantly on operating costs to operate on the Nano network.
The image above outlines the flow of messages within the system. Services request a proof of work for a specific block (hash) from the server. The server broadcasts a request using the low-latency MQTT protocol. The first worker (client) to return valid work is rewarded, and immediately a message is sent so other clients know they can cancel the ongoing computation. Meanwhile, the work is returned to the service.
You can read more about the DPoW message specification.

We have made efforts to make it easier for anyone to run a DPoW server for themselves. If you need any assistance, please use the discord server or Github issues page.
- P2PoW is a P2P protocol which allows users to trustlessly request work from others. It is more inefficient than DPoW, as it requires two blocks for each request, but removes the middleman (server) which is a central point of failure of the system.
