(Carl Dong) Pull request description: ~~**This post is kept updated as this project progresses.

[Guix](https://www.gnu.org/software/guix/manual/en/html_node/Features.html) is a transactional package manager much like Nix, but unlike Nix, it has more of a focus on [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) and [reproducibility](https://www.gnu.org/software/guix/blog/tags/reproducible-builds/) which are attractive for security-sensitive projects like bitcoin. ### Guix Build Walkthrough Please read the `README.md`. [Old instructions no. 4](https://github.com/bitcoin/bitcoin/pull/15277#issuecomment-497303718) [Old instructions no. 3](https://github.com/bitcoin/bitcoin/pull/15277#issuecomment-493827011) [Old instructions no. 2](https://github.com/bitcoin/bitcoin/pull/15277#issuecomment-471658439) <details> <summary>Old instructions no. 1</summary> In this PR, we define a Guix [manifest](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#profile_002dmanifest) in `contrib/guix/manifest.scm`, which declares what packages we want in our environment. We can then invoke ``` guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes ``` To have Guix: 1. Build an environment containing the packages we defined in our `contrib/guix/manifest.scm` manifest from the Guix bootstrap binaries (see [bootstrappability](https://www.gnu.org/software/guix/manual/en/html_node/Bootstrapping.html) for more details). 2. Start a container with that environment that has no network access, and no access to the host's filesystem except to the `pwd` that it was started in. 3. Drop you into a shell in that container. > Note: if you don't want to wait hours for Guix to build the entire world from scratch, you can eliminate the `--no-substitutes` option to have Guix download from available binary sources. Note that this convenience doesn't necessarily compromise your security, as you can check that a package was built correctly after the fact using `guix build --check <packagename>` Therefore, we can perform a build of bitcoin much like in Gitian by invoking the following: ``` make -C depends -j"$(nproc)" download && \ cat contrib/guix/build.sh | guix environment --manifest=contrib/guix/manifest.scm --container --pure --no-grafts --no-substitutes ``` We don't include `make -C depends -j"$(nproc)" download` inside `contrib/guix/build.sh` because `contrib/guix/build.sh` is run inside the container, which has no network access (which is a good thing). </details> ### Rationale I believe that this represents a substantial improvement for the "supply chain security" of bitcoin because: 1. We no longer have to rely on Ubuntu for our build environment for our releases ([oh the horror]( |

Repository Tools
Developer tools
Specific tools for developers working on this repository.
Contains the script github-merge.py for merging GitHub pull requests securely and signing them using GPG.
Verify-Commits
Tool to verify that every merge commit was signed by a developer using the above github-merge.py script.
Linearize
Construct a linear, no-fork, best version of the blockchain.
Qos
A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Dash network. This means one can have an always-on dashd instance running, and another local dashd/dash-qt instance which connects to this node and receives blocks from it.
Seeds
Utility to generate the pnSeed[] array that is compiled into the client.
Build Tools and Keys
Debian
Contains files used to package dashd/dash-qt for Debian-based Linux systems. If you compile dashd/dash-qt yourself, there are some useful files here.
Gitian-descriptors
Notes on getting Gitian builds up and running using KVM.
Gitian-keys
PGP keys used for signing Dash Core Gitian release results.
MacDeploy
Scripts and notes for Mac builds.
Gitian-build
Script for running full Gitian builds.
Test and Verify Tools
TestGen
Utilities to generate test vectors for the data-driven Dash tests.
Verify Binaries
This script attempts to download and verify the signature file SHA256SUMS.asc from bitcoin.org.
