How to get Tezos¶
In this how-to we explain how to get up-to-date binaries to run Tezos on any network (either on the mainnet or on one of the test networks). Tezos consists of several binaries (i.e., executable files), including: a client, a node, a baker, and an endorser.
There are several options for getting the binaries, depending on how you plan to use Tezos:
getting static binaries. This is the easiest way to get native binaries for the latest stable release, requiring no dependencies, under Linux.
installing binaries. This is the easiest way to install native binaries for the latest stable release, together with their dependencies, using a package manager.
using docker images. This is the easiest way to run the latest stable release of the binaries in Docker containers, on any OS supported by Docker.
building the binaries via the OPAM source package manager. Take this way to install the latest stable release in your native OS environment, automatically built from sources.
setting up a complete development environment by compiling the sources like developers do. This is the way to take if you plan to contribute to the source code. It allows to install any version you want (typically, the current development version on the master branch) by compiling it yourself from the sources.
These different options are described in the following sections.
Note that some of the packaged distributions are not only available for the latest stable release. For instance, static binaries are also available for release candidates, and Docker images are also available for the current developement version (see Release system for more information).
When choosing between the installation options, you may take into account the convenience of the installation step (and of upgrading steps), but also efficiency and security considerations. For instance, static binaries have a different memory footprint compared to dynamically-linked binaries. Also, compiling the sources in the official Tezos repository is more secure than installing OPAM packages from a repository that is not under Tezos control. In particular, compiling from sources enforces a fixed set of dependencies; when compiling via OPAM, this set of dependencies may change, which may or may not be compatible with your security practices.
Getting static binaries¶
You can get static Linux binaries from the latest release in the tezos-packaging repository.
This repository provides static binaries for x86_64 and arm64 architectures. Since these binaries are static, they can be used on any Linux distribution without any additional prerequisites. However, note that, by embedding all dependencies, static binary executables are typically much larger than dynamically-linked executables.
For upgrading to a newer release, you just have to download and run the new versions of the binaries.
Depending on your operating system, you may install Tezos (dynamically-linked) binaries and their dependencies using a package manager, as follows.
Ubuntu Launchpad PPA with Tezos packages¶
If you’re using Ubuntu, you can install packages with Tezos binaries from the Launchpad PPA. Currently it supports Focal and Bionic versions. In order to add the PPA repository to your machine and install the binaries, run the following commands:
sudo add-apt-repository ppa:serokell/tezos && sudo apt-get update sudo apt-get install -y tezos-client sudo apt-get install -y tezos-node sudo apt-get install -y tezos-baker-009-psfloren sudo apt-get install -y tezos-endorser-009-psfloren sudo apt-get install -y tezos-accuser-009-psfloren
Upgrading to a newer release is made easy by the APT package manager, using
commands such as
apt-get upgrade <package>, and
apt-get install <new-package>. Indeed, as the names of some packages (e.g.
the baker) depend on their version, you may have to also install new packages.
You may take a look at the available packages in the Tezos PPA repository listed
Fedora Copr repository with Tezos packages¶
If you’re using Fedora, you can install packages with Tezos binaries from the Copr repository. Currently it supports Fedora 32 and 33. In order to dd the Copr repository to your machine and install the binaries, run the following commands:
dnf copr enable -y @Serokell/Tezos && dnf update -y dnf install -y tezos-client dnf install -y tezos-node dnf install -y tezos-baker-009-PsFLoren dnf install -y tezos-endorser-009-PsFLoren dnf install -y tezos-accuser-009-PsFLoren
Upgrading to a newer release is made easy by the DNF package manager, using
commands such as
dnf upgrade <package>, and
dnf install <new-package>. Indeed, as the names of some packages (e.g.
the baker) depend on their version, you may have to also install new packages.
You may take a look at the available packages in the Tezos Copr repository
Using Docker images¶
For every change committed in the GitLab repository, Docker images are
automatically generated and published on DockerHub. This provides a convenient
way to run an always up-to-date
tezos-node. The script
tezos-docker-manager.sh (formally known as
provided to download the right image for each network and run a
simple node. Its only requirement is a working installation of
Docker (including both Docker Engine and Docker Compose) on a machine
with architecture x86_64. Although we only officially support
Linux, the script has been tested with success in the past on
Windows, OS X, and Linux.
The same script can be used to run Tezos on Mainnet, on Florencenet, or on other network: it suffices to rename it as it downloads a different image based on its name. For example, to run Tezos on the Florencenet test network with the latest release:
wget -O florencenet.sh https://gitlab.com/tezos/tezos/raw/latest-release/scripts/tezos-docker-manager.sh chmod +x florencenet.sh
Alternatively, to run on Mainnet:
wget -O mainnet.sh https://gitlab.com/tezos/tezos/raw/latest-release/scripts/tezos-docker-manager.sh chmod +x mainnet.sh
In the following we assume you are running on the florencenet test network. You are now one step away from a working node:
This will download the right Docker image for your chosen network, launch 3 Docker containers running the node, the baker and the endorser. Keep in mind that when a Tezos node is launched, it needs to connect to new peers and synchronize the chain. This can be lengthy on the first launch considering that the chain takes up several gigabytes of data. See how to use Tezos for more details.
Every call to
florencenet.sh will check for updates of the node and
will fail if your node is not up-to-date. For updating the node, simply
If you prefer to temporarily disable automatic updates, you just have to set an environment variable:
./florencenet.sh --help for more information about the
script. In particular see
./florencenet.sh client --help or the
online manual for more information about
the client. Every command to the
tezos-client can be equivalently
executed by using
./florencenet.sh client, passing the needed arguments. Similarly,
can be executed using
Building from sources via OPAM¶
The easiest way to build the binaries from the source code is to use the OPAM source package manager for OCaml.
Currently Tezos is being developed for Linux x86_64, mostly for Debian/Ubuntu and Arch Linux. The following OSes are also reported to work: macOS (x86_64), Arch Linux ARM (aarch64), Debian Linux (buster), Ubuntu Linux (focal). A Windows port is feasible and might be developed in the future.
If you build the binaries by using the following instructions inside a
Docker container, you have to give extended privileges to this container,
by passing option
--privileged to the
docker run command.
After the first install of OPAM, use
opam init --bare to set it up
while avoiding to compile an OCaml compiler now, as this will be done in
the next step.
Install Tezos OPAM packages¶
The latest Tezos release is available (as soon as possible after the release) directly as OPAM packages.
Every file related to OPAM is (by default) in
means that, first, OPAM installs are user-specific and, second, you
can get rid of everything by removing this directory (+ updating
your rc files (
$HOME/.emacs, …) if you asked/allowed OPAM
to add some lines in them).
The binaries need a specific version of the OCaml compiler (see the value
$ocaml_version in file
scripts/version.sh). To get an environment with it do:
wget -O latest-release:version.sh https://gitlab.com/tezos/tezos/raw/latest-release/scripts/version.sh source latest-release:version.sh opam switch create for_tezos $ocaml_version eval $(opam env)
eval $(opam env) sets up required environment
variables. OPAM will suggest to add it in your rc file. If, at any
point, you get an error like
tezos-something: command not
found, first thing to try is to (re)run
env --switch $ocaml_version) (replace
$ocaml_version with its value
scripts/version.sh) to see if it fixes the problem.
In order to get the system dependencies of the binaries, do:
opam install depext opam depext tezos
If an OPAM commands times out, you may allocate it more time for its
computation by setting the OPAMSOLVERTIMEOUT environment variable (to a
number of seconds), e.g. by adding
OPAMSOLVERTIMEOUT=1200 before the
command. If no timeout occurs, you may omit this part.
Now, install all the binaries by:
opam install -y tezos
You can be more specific and only
opam install tezos-node,
install tezos-endorser-009-PsFLoren, … In that case, it is enough to install the system dependencies of this package only by running
opam depext tezos-node for example instead of
opam depext tezos.
opam install tezos-client and
tezos-signer are “minimal” and do not install the support for
Ledger Nano devices. To enable it, run
ledgerwallet-tezos in addition to installing the binaries. (The
Updating via OPAM¶
Installation via OPAM is especially convenient for updating to newer versions. Once some libraries/binaries are installed and new versions released, you can update by:
opam update opam depext opam upgrade
It is recommended to also run the command
opam remove -a in order
to remove the dependencies installed automatically and not needed
anymore. Beware not uninstall too much though.
Identified situations where it will be more tricky are:
When the OCaml compiler version requirement changes. In this case, be explicit about the “upgrade” and do
opam upgrade --unlock-base ocaml.$new_version tezos.
When there are Rust dependencies involved. The way to go is still unclear. The solution will be defined when delivering the first release with Rust dependencies.
Setting up the development environment from scratch¶
If you plan to contribute to the Tezos codebase, the way to go is to set up a complete development environment, by cloning the repository and compiling the sources using the provided makefile.
TL;DR: From a fresh Debian Buster x86_64, you typically want to do:
sudo apt install -y rsync git m4 build-essential patch unzip wget pkg-config libgmp-dev libev-dev libhidapi-dev libffi-dev opam jq zlib1g-dev # [install rust] wget https://sh.rustup.rs/rustup-init.sh chmod +x rustup-init.sh ./rustup-init.sh --profile minimal --default-toolchain 1.44.0 -y # [source cargo] source $HOME/.cargo/env # [get sources] git clone https://gitlab.com/tezos/tezos.git cd tezos git checkout latest-release # [install Tezos dependencies] opam init --bare make build-deps # [compile sources] eval $(opam env) make # [optional setup] export PATH=~/tezos:$PATH source ./src/bin_client/bash-completion.sh export TEZOS_CLIENT_UNSAFE_DISABLE_DISCLAIMER=Y
The following sections describe the individual steps above in more detail.
Compiling Tezos requires the Rust compiler,
version 1.44.0, and the Cargo package manager to be installed. If you
have rustup installed, it should work without
any additional steps on your side. You can use rustup to install both. If you do not have
please avoid installing it from Snapcraft; you can rather follow the
simple installation process shown below:
wget https://sh.rustup.rs/rustup-init.sh chmod +x rustup-init.sh ./rustup-init.sh --profile minimal --default-toolchain 1.44.0 -y
Once Rust is installed, note that your
PATH environment variable
.profile) may be updated and you will need to restart your session
so that changes can be taken into account. Alternatively, you can do it
manually without restarting your session:
Note that the command line above assumes that rustup
installed Cargo in
$HOME/.cargo, but this may change depending on how
you installed rustup. See the documentation of your rustup distribution
.cargo does not exist in your home directory.
Install Zcash Parameters¶
Tezos binaries require the Zcash parameter files to run.
Docker images come with those files, and the source distribution also
includes those files. But if you compile from source and move Tezos to
another location (such as
/usr/local/bin), the Tezos binaries may
prompt you to install the Zcash parameter files. The easiest way is to
download and run this script:
The node will try to find Zcash parameters in the following directories, in this order:
$XDG_DATA_DIRScontains several paths separated by colons
:, each path is considered)
If the node complains that it cannot find Zcash parameters, check that
at least one of those directories contains both files
sapling-output.params. Here is where you should expect to find those files:
if you are compiling from source, parameters should be in
_opam/share/zcash-params(you may need to run
eval $(opam env)before running the node);
if you used
fetch-params.sh, parameters should be in
Some operating systems may not be covered by the list of directories above.
If Zcash is located elsewhere on your system (typically, on MacOS X), you may try creating a symbolic link such as:
ln -s ~/Library/Application\ Support/ZcashParams ~/.zcash-params.
Get the sources¶
latest-release branch to use the latest release.
Alternatively, you can checkout a specific version based on its tag.
Install Tezos dependencies¶
Install the OCaml compiler and the libraries that Tezos depends on:
Alternatively, if you want to install extra
development packages such as
merlin, you may use the following
These commands create a local OPAM switch (
_opamfolder at the root of the repository) where the required version of OCaml and OCaml Tezos dependencies are compiled and installed (this takes a while but it’s only done once).
Be sure to
eval $(scripts/env.sh)when you
cdinto the repository in order to be sure to load this local environment.
As the opam hook would overwrite the effects of
eval $(scripts/env.sh)the script will disable the opam hook temporarily.
OPAM is meant to handle correctly the OCaml libraries but it is not always able to handle all external C libraries we depend on. On most systems, it is able to suggest a call to the system package manager but it currently does not handle version checking.
As a last resort, removing the
_opamfolder (as part of a
git clean -dxffor example) allows to restart in a fresh environment.
Once the dependencies are installed we can update OPAM’s environment to refer to the new switch and compile the project:
eval $(opam env) make
Lastly, you can also add the Tezos binaries to your
and after reading the Disclaimer a few
hundred times you are allowed to disable it with
You may also activate Bash autocompletion by executing:
Note that if your shell is zsh, you may need extra configuration to customize shell completion (refer to the zsh documentation).
For updating to a new version, you typically have to
update the sources by doing
git pull in the
tezos/ directory and replay
the compilation scenario starting from
You may also use
make clean (and
rm -Rf _opam/ if needed) before that, for restarting compilation in a
