Download the binary and matching .sha256 file for your platform into the same
directory. Then verify the checksum before staging the binary.

AMD64:

curl -fL -O https://github.com/medibloc/panacea-core/releases/download/v2.3.0/panacead-linux-amd64
curl -fL -O https://github.com/medibloc/panacea-core/releases/download/v2.3.0/panacead-linux-amd64.sha256

sha256sum -c panacead-linux-amd64.sha256
chmod +x panacead-linux-amd64
./panacead-linux-amd64 version --long | grep -E '^(version|commit):'

ARM64:

curl -fL -O https://github.com/medibloc/panacea-core/releases/download/v2.3.0/panacead-linux-arm64
curl -fL -O https://github.com/medibloc/panacea-core/releases/download/v2.3.0/panacead-linux-arm64.sha256

sha256sum -c panacead-linux-arm64.sha256
chmod +x panacead-linux-arm64
./panacead-linux-arm64 version --long | grep -E '^(version|commit):'

The checksum command must report OK. The final command must report version
2.3.0 and commit
