Merge bitcoin/bitcoin#25970: Add headerssync tuning parameters optimization script to repo 
3d420d8f28 Add instructions for headerssync-params.py to release-process.md (Pieter Wuille)
53d7d35b58 Update parameters in headerssync.cpp (Pieter Wuille)
7899402cff Add headerssync-params.py script to the repository (Pieter Wuille)

Pull request description:

  Builds upon #25946, as it incorporates changes based on the selected values there.

  This adds the headerssync tuning parameters optimization script from https://gist.github.com/sipa/016ae445c132cdf65a2791534dfb7ae1 to the repository, updates the parameters based on its output, and adds release process instructions for doing this update in the future.

  A few considerations:
  * It would be a bit cleaner to have these parameters be part of `CChainParams`, but due to the nature of the approach, it really only applies to chains with unforgeable proof-of-work, which we really can only reasonably expect from mainnet, so I think it's fine to keep them local to `headerssync.cpp`. Keeping them as compile-time evaluatable constants also has a (likely negligible) performance impact (avoiding runtime modulo operations).
  * If we want to make sure the chainparams and headerssync params don't go out of date, it could be possible to run the script in CI, and and possibly even have the parameters be generated automatically at build time. I think that's overkill for how unfrequently these need to change, and running the script has non-trivial cost (~minutes in the normal python interpreter).
  * A viable alternative is just leaving this out-of-repo entirely, and just do ad-hoc updating from time to time. Having it in the repo and release notes does make sure it's not forgotten, though adds a cost to contributors/maintainers who follow the process.

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) or
  • bin/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.
