Bitcoin Core Release Signing Keys v0.11.0+
Check your bandwidth and space
Bitcoin Core requires a one-time download of about 180GB of data plus a further 5-10GB per month. By default, you will need to store all of that data, but if you enable pruning, you can store as little as 6GB total without sacrificing any security. For more information about setting up Bitcoin Core, please read the full node guide.
