Donate Bandwidth Using Bitcoin Core

Support the network

Download Bitcoin Core
Bitcoin Core 27.0
Windows Mac Linux

The Bitcoin peer-to-peer network serves both Bitcoin Core and many other Bitcoin programs (mostly lightweight wallets). By contributing some of your bandwidth—typically about 100 GB upload a month—you can help support Bitcoin.

The bandwidth sharing guide provides all of the details you need to begin donating bandwidth.

Don’t Forget About Decentralization

The Bitcoin network needs more than bandwidth—it also needs people who actively secure their bitcoins using Bitcoin Core. By securing your bitcoins with a full node like Bitcoin Core, you help protect Bitcoin’s decentralization for yourself and other Bitcoin users.

You can help protect decentralization instead of donating bandwidth by simply using Bitcoin Core as your main wallet. Or, even better, you can both donate bandwidth and protect decentralization at the same time by using Bitcoin Core as your main wallet while also following the instructions in the bandwidth sharing guide.

Thank You

Whether you choose to donate bandwidth, protect decentralization, or both, please know that your fellow Bitcoin users thank you. Without volunteers like you, Bitcoin would never have come as far as it has.
