Version 23.2

Version 23.2#

Changes#

Summary#

Version 23 introduces the following changes or new features:

  1. Support of the Seoul Protocol proposal (See the protocol support section)

  2. Release of the octez-baker executable (See the octez-baker executable section)

  3. BLS support (See the BLS support section)

  4. New snapshot version (See the snapshot version section)

Octez v23.1 addresses an issue with Ubuntu and Debian packages distribution, where an expired PGP key prevented users from updating to v23.0 using apt.

Octez v23.2 fixes an issue affecting systemd services of Debian and Ubuntu packages that could lead to having two baking binaries running at the same time.

In some cases, this issue could cause bakers to lose consensus rewards or, in certain conditions, could result in double-signing. Consequently, v23.0 and v23.1 Ubuntu and Debian packages were made unavailable via apt and dnf. The release of v23.2 restores the availability of these distribution packages.

For all other distributions, this version is the same as Octez v23.1

Protocol Support#

Version 23 contains a new version (V15) of the protocol environment. As a result, Octez version 23 is the first version compatible with all protocols that require this environment, such as the Seoul protocol proposal.

Octez-baker executable#

Starting from v23, the octez-baker executable is released. This binary is a protocol-independent that dynamically selects the appropriate baking process based on the active protocol.

The bakers names with protocols are still released, but they will be deprecated in an upcoming version.

Similarly, there is also a protocol-independent binary octez-accuser starting from v23.

BLS support#

Version 23 contains client commands and node RPCs that support Tz4 delegates and Native multisig.

Warning

The introduction of this feature entailed a few breaking changes, so it is recommended to update any tool producing or processing reveal operations to a Seoul-compatible version…

Snapshot version#

Octez version 23 has a new snapshot version (version 9), improving baking support just after importing a snapshot.

Snapshots of version 8 exported with previous versions of Octez can still be imported, snapshots of version 9 are not retro-compatible with previous Octez versions.

Minimal hardware specifications#

Our benchmarks suggest the following minimal specs for Octez node and baker operators:

  • 3 CPU cores: 2 needed by the node and 1 needed by the baker (arm64 or amd64/x86-64)

  • 8GB of RAM + 8GB of swap (or 16GB of RAM)

  • 100GB SSD storage (or similar I/O performance)

  • A low-latency reliable internet connection

This configuration has been tested for running an Octez node in rolling history mode. Other more specific uses may need adequate configurations. For instance:

  • running a node in full or archive mode requires extra storage space;

  • bakers participating to the DAL should consult The DAL node requirements.

Update Instructions#

Ubuntu and Debian packages#

Note

Because the PGP keys have been rotated, users updating packages need to overwrite the previously installed octez.gpg key. For example, in order to update to v23.2 from a pre-existing Ubuntu Noble deployment, a user should first update the keys with:

curl -s "https://packages.nomadic-labs.com/ubuntu/octez.asc" |
    sudo gpg --yes --dearmor -o /etc/apt/keyrings/octez.gpg

Then, Octez packages users are advised to stop systemd services before updating to v23.2:

sudo apt-get update
sudo apt-get upgrade octez-baker

See the install instructions for Ubuntu and Debian packages for details, or if you are installing Ubuntu and Debian packages from scratch.

Warning

If you are running the Octez node with a non-default data directory, check instructions here.

Fedora or Rocky Linux packages#

dnf -y update octez-node  octez-client octez-baker octez-dal-node octez-smart-rollup-node

If you are installing Ubuntu and Debian packages from scratch, follow their install instructions

From sources#

git fetch
git checkout octez-v23.2
make clean
opam switch remove . # To be used if the next step fails
make build-deps
eval $(opam env)
make

If you are using Docker instead, use the octez-v23.2 Docker images of Octez.
