Migration to v0.3.0

Release Notes

For Linux AMD Distributions

Download the tar.gz file:

curl -LO https://github.com/empe-io/empe-chain-releases/raw/master/v0.3.0/emped_v0.3.0_linux_amd64.tar.gz

Verify the checksum (change filename for ARM):

sha256sum emped_v0.3.0_linux_amd64.tar.gz

You should see the following:

2bfe1bc92b5d5e20e72bcc7a3b24661fb30d74a050a915e4c6eaeba9fe41811b  emped_v0.3.0_linux_amd64.tar.gz

Unpack the tar.gz file:

tar -xvf emped_v0.3.0_linux_amd64.tar.gz

Move the binary to your local bin directory:

mkdir -p ~/go/bin
sudo mv emped ~/go/bin

Install wasmvm library

Create a directory for the library

mkdir ~/.empe-chain/lib

Download the library to the directory

wget https://github.com/CosmWasm/wasmvm/releases/download/v1.5.2/libwasmvm.x86_64.so -P ~/.empe-chain/lib

Add the library to the path

echo 'export LD_LIBRARY_PATH=/home/$USER/.empe-chain/lib:$LD_LIBRARY_PATH' >> ~/.profile
source ~/.profile

Check the version

emped version

You should see the following:

0.3.0

Setup cosmovisor

Create cosmovisor upgrade dir

export DAEMON_HOME=$HOME/.empe-chain/
mkdir -p $DAEMON_HOME/cosmovisor/upgrades/v0.3.0/bin

Put binary in proper dir

cp ~/go/bin/emped $DAEMON_HOME/cosmovisor/upgrades/v0.3.0/bin

Just to be sure check version (should be 0.3.0)

$DAEMON_HOME/cosmovisor/upgrades/v0.3.0/bin/emped version

Add wasmvm path to cosmovisor service

Add the following line to the cosmovisor service file under the [Service] section. Remember to change user_path to your actual path

Environment="LD_LIBRARY_PATH=/home/user_path/.empe-chain/lib:$LD_LIBRARY_PATH"

Restart the cosmovisor service

sudo systemctl daemon-reload
sudo systemctl restart cosmovisor

For Linux ARM Distribution

If (and only if) you're running ARM Linux, download this file instead:

curl -LO https://github.com/empe-io/empe-chain-releases/raw/master/v0.3.0/emped_v0.3.0_linux_arm64.tar.gz

Verify the checksum

sha256sum emped_v0.3.0_linux_arm64.tar.gz

You should see the following:

c46e8a589e62febbd2b9b6b14f610e504e35d7a547ed6bac380fcdd01acd6f8f  emped_v0.3.0_linux_arm64.tar.gz

Unpack the tar.gz file:

tar -xvf emped_v0.3.0_linux_arm64.tar.gz

Install wasmvm library

Create a directory for the library

mkdir ~/.empe-chain/lib

Download the library to the directory

wget https://github.com/CosmWasm/wasmvm/releases/download/v1.5.2/libwasmvm.aarch64.so -P ~/.empe-chain/lib

Add the library to the path

echo 'export LD_LIBRARY_PATH=/home/$USER/.empe-chain/lib:$LD_LIBRARY_PATH' >> ~/.profile
source ~/.profile

Check the version

emped version

You should see the following:

0.3.0

Continue with the shared steps

The remaining steps are identical to the AMD distribution. Continue with:

• Move the binary to your local bin directory — mkdir -p ~/go/bin && sudo mv emped ~/go/bin

• Setup cosmovisor — create $DAEMON_HOME/cosmovisor/upgrades/v0.3.0/bin and copy the binary into it

• Add wasmvm path to cosmovisor service

• Restart the cosmovisor service
