Akash v1.1.0 Node Upgrade Guide

Upgrade Details

• Upgrade name: Mainnet15
• Binary version: v1.1.0
• Block height: 24332547
• Estimated time: Monday, November 24th, 2025 at 14:10 UTC
• Expected duration: 10-15 minutes of network downtime
• Binary release: Available approximately 10 hours before the upgrade
• Binary Links

⚠️ Note: Block times have high variance. Please monitor the block countdown for more precise timing estimates.

Validator Expectations

To ensure a network upgrade with minimal downtime, Akash Validators should be available as follows:

• One hour prior to upgrade - available and monitoring the Akash Discord server’s validator and validator-announcement channels for any late breaking guidance

• Available throughout the network upgrade window (expected 10-15 minutes)

• One hour post upgrade - available and monitoring the Akash Discord server’s validator and validator-announcement channels for any possible revised strategies or updates deemed necessary

Emergency Coordination

In the event of issues during the upgrade, please coordinate via the validators channel in Discord to reach emergency consensus and mitigate problems quickly.

Hardware Requirements

This upgrade does not carry significant state changes and is relatively light-weight. It is recommended for all validators to use at least 64GB of RAM with swap enabled.

Upgrade Process

In the sections that follow, both Cosmovisor (recommended) and non-Cosmovisor (manual) upgrade paths are provided. Full upgrade details and coordination can be found via the Akash Discord validators channel.

Option 1: Upgrade Using Cosmovisor (Recommended)

The following instructions assume the akash and cosmovisor binaries are already installed and cosmovisor is set up as a systemd service.

The section that follows will detail the install/configuration of Cosmovisor. If additional details are necessary, visit the Cosmovisor documentation for instructions on how to install and set up the binaries.

NOTE - Cosmovisor 1.5.0 or higher is required

Validators and RPCs supervised by Cosmovisor with DAEMON_ALLOW_DOWNLOAD_BINARIES=true will automatically download upgrade binaries from the upgrade info file.

Configure Cosmovisor

Note: The following steps are not required if Cosmovisor v1.5.0+ is already installed and configured to your preferred settings.

To install cosmovisor by running the following command:

go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

Check to ensure the installation was successful:

DAEMON_NAME=akash DAEMON_HOME=~/.akash cosmovisor version

Update cosmovisor systemd service file and make sure the environment variables are set to the appropriate values (the following example includes the recommended settings).

• NOTE - It is preferable if you start your service under a dedicated non-system user other than root.
• NOTE - DAEMON_SHUTDOWN_GRACE (optional, default none), if set, send interrupt to binary and wait the specified time to allow for cleanup/cache flush to disk before sending the kill signal. The value must be a duration (e.g. 1s).

Cosmovisor can be configured to automatically download upgrade binaries. It is recommended that validators do not use the auto-download option and that the upgrade binary is compiled and placed manually.

If you would like to enable the auto-download option, update the following environment variable in the systemd configuration file:

Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"

Cosmovisor will automatically create a backup of the data directory at the time of the upgrade and before the migration.

If you would like to disable the auto-backup, update the following environment variable in the systemd configuration file:

Environment="UNSAFE_SKIP_BACKUP=true"

Move the file to the systemd directory:

sudo mv cosmovisor.service /etc/systemd/system/akash.service

Restart cosmovisor to ensure the environment variables have been updated:

systemctl daemon-reload
systemctl start akash
systemctl enable akash

Check the status of the cosmovisor service:

sudo systemctl status cosmovisor

Enable cosmovisor to start automatically when the machine reboots:

sudo systemctl enable cosmovisor.service

Download Precompiled Binary (Recommended)

NOTE - Skip this section if you have enabled DAEMON_ALLOW_DOWNLOAD_BINARIES=true in your Cosmovisor configuration. It will automatically create the correct path and download the binary based on the plan info from the governance proposal.

This upgrade links an info.json file that references the correct release with pre-built binaries.

Download the Akash binary for your platform from the GitHub releases page.

If you need to build the binary from source instead, see the Build Binary From Sources section in the Appendix.

Prepare Upgrade Binary

Create the folder for the upgrade (v1.1.0) and copy the akash binary into the folder:

# Create the upgrade directory
mkdir -p $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin

# Copy the downloaded binary (adjust path to your download location)
cp /path/to/downloaded/akash $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin/akash

# Make it executable
chmod +x $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin/akash

# Verify the version
$HOME/.akash/cosmovisor/upgrades/v1.1.0/bin/akash version

If you built from source, the binary will be in .cache/goreleaser/main/<YOUR_OS_ARCH>/akash - see Build Binary From Sources for details.

At the proposed block height (24332547), cosmovisor will automatically stop the current binary (v1.0.0), set the upgrade binary as the new current binary (v1.1.0), and then restart the node.

Option 2: Manual Upgrade Without Cosmovisor

Using Cosmovisor to perform the upgrade is not mandatory.

Node operators also have the option to manually update the akash binary at the time of the upgrade.

⚠️ Warning: Do NOT replace the binary before the upgrade height, as this will stop your node.

Manual Upgrade Steps

1. Wait for the chain to halt at block height 24332547

2. Stop your node (if not already stopped)

3. Install the new binary - Either download the Akash binary or build from source (see Build Binary From Sources)

4. Verify the binary version:

   akash version
   # Should output: v1.1.0

5. Restart your node

Appendix

Build Binary From Sources

NOTE - We highly recommend downloading a precompiled Akash binary over building from source. Only use this method if precompiled binaries are not available for your platform or if you have specific requirements.

Prerequisites

Ensure the following dependencies are installed before building:

Direnv Setup

If using direnv for the first time (or cloning sources onto a new host), you should see the following message after entering the source directory:

direnv: error .envrc is blocked. Run `direnv allow` to approve its content

If you don’t see this message, direnv is likely not hooked to your shell. Visit direnv.net for installation and shell integration instructions.

Build Steps

Follow these steps to build the v1.1.0 binary from source:

# Clone the repository
git clone https://github.com/akash-network/node.git

# Navigate to the directory
cd node

# Checkout the release tag
git checkout v1.1.0

# Allow direnv to set up the environment
direnv allow

# Build the release binary
make release

Build Output

After the build completes successfully, binaries will be located in .cache/goreleaser/main.

The directory structure will look like:

.cache/goreleaser/main/
├── darwin_amd64_v1/
│   └── akash
├── darwin_arm64/
│   └── akash
├── linux_amd64_v1/
│   └── akash
├── linux_arm64/
│   └── akash
└── ... (other platforms)

Select the directory matching your operating system and architecture:

• Linux AMD64: linux_amd64_v1/akash
• Linux ARM64: linux_arm64/akash
• macOS Intel: darwin_amd64_v1/akash
• macOS Apple Silicon: darwin_arm64/akash

Verify the Build

After building, verify the binary version:

.cache/goreleaser/main/<YOUR_OS_ARCH>/akash version
# Should output: v1.1.0

Using the Built Binary

For Cosmovisor, copy the built binary to the upgrade directory:

mkdir -p $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin
cp .cache/goreleaser/main/<YOUR_OS_ARCH>/akash $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin/akash
chmod +x $HOME/.akash/cosmovisor/upgrades/v1.1.0/bin/akash

For manual upgrade, copy the binary to your system path or use it directly when the upgrade height is reached.
