This requires a linux kernel of 3.17.0+, which seems entirely reasonable. 3.17 went EOL in 2015, and the last supported 3.x kernel (3.16) went EOL > 4 years ago, in 2020. For reference, the current oldest maintained kernel is 4.14 (released 2017, EOL Jan 2024). Support for `getrandom()` (and `getentropy()`) was added to glibc 2.25, https://sourceware.org/legacy-ml/libc-alpha/2017-02/msg00079.html, and we already require 2.27+. All that being said, I don't think you would encounter a current day system, running with kernel headers older than 3.17 (released 2014) but also having a glibc of 2.27+ (released 2018). |

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
