+## Reproducible builds
+
+Reproducibility is a goal of the Sparrow Wallet project. 
+As of v1.5.0 and later, it is possible to recreate the exact binaries in the Github releases (specifically, the contents of the `.tar.gz` and `.zip` files).
+
+Due to minor variances, it is not yet possible to reproduce the installer packages (`.deb`, `.rpm` and `.exe`).
+In addition, the OSX binary is code signed and thus can't be directly reproduced yet. 
+Work on resolving both of these issues is ongoing.
+
+### Reproducing a release
+
+#### Install Java
+
+Because Sparrow bundles a Java runtime in the release binaries, it is essential to have the same version of Java installed when creating the release.
+For v1.6.4 and later, this is Eclipse Temurin 17.0.2+8. 
+It is available for all supported platforms from [Eclipse Temurin 17.0.2+8](https://github.com/adoptium/temurin17-binaries/releases/tag/jdk-17.0.2%2B8).
+
+For reference, the downloads are as follows:
+- [Linux x64](https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.2%2B8/OpenJDK17U-jdk_x64_linux_hotspot_17.0.2_8.tar.gz)
+- [MacOS x64](https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.2%2B8/OpenJDK17U-jdk_x64_mac_hotspot_17.0.2_8.tar.gz)
+- [MacOS aarch64](https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.2%2B8/OpenJDK17U-jdk_aarch64_mac_hotspot_17.0.2_8.tar.gz)
+- [Windows x64](https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.2%2B8/OpenJDK17U-jdk_x64_windows_hotspot_17.0.2_8.zip)
+
+It is also possible to install via a package manager on *nix systems. For example, on Debian/Ubuntu systems:
+```shell
+sudo apt-get install -y wget apt-transport-https gnupg
+wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -
+echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list
+sudo apt update -y
+sudo apt-get install -y temurin-17-jdk=17.0.2+8
+sudo update-alternatives --config java
+```
+
+A alternative option for all platforms is to use the [sdkman.io](https://sdkman.io/) package manager ([Git Bash for Windows](https://git-scm.com/download/win) is a good choice on that platform).
+See the installation [instructions here](https://sdkman.io/install).
+Once installed, run
+```shell
+sdk install java 17.0.2-tem
+```
+
+#### Other requirements
+
+Other packages may also be necessary to build depending on the platform. On Debian/Ubuntu systems:
+```shell
+sudo apt install -y rpm fakeroot binutils
+```
+
+#### Building the binaries
+
+The project can cloned for a specific release tag as follows:
+```shell
+GIT_TAG="1.6.6"
+git clone --recursive --branch "${GIT_TAG}" git@github.com:sparrowwallet/sparrow.git
+```
+
+Thereafter, building should be straightforward:
+
+```shell
+cd sparrow
+./gradlew jpackage
+```
+
+The binaries (and installers) will be placed in the `build/jpackage` folder.
+
+#### Verifying the binaries are identical
+
+Note that you will be verifying the files in the `build/jpackage/Sparrow` folder against either the `.tar.gz` or `.zip` releases.
+Download either of these depending on your platform and extract the contents to a folder (in the following example, `/tmp`).
+Then compare all of the folders and files recursively:
+
+```shell
+diff -r build/jpackage/Sparrow /tmp/Sparrow
+```
+
+This command should have no output indicating that the two folders (and all their contents) are identical.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
