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:

bb5100b8dbc6c3f8ca117898e8fcfaf714f989562ce4df386192882642f94b3d  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:

103561cf95016ddbe807a671cc9a98281356fa9d1643075fed6f082ee51b4cd6  emped_v0.3.0_linux_arm64.tar.gz

Unpack the tar.gz file:

tar -xvf emped_v0.3.0_linux_arm64.tar.gz
