I follow the instructions (see notes):

git clone https://github.com/crypto-org-chain/cronos-blockscout.git
cd cronos-blockscout
asdf install
export DATABASE_URL=postgresql://<username>:<username_password>@localhost:5432/blockscout
mix do deps.get, local.rebar --force, deps.compile
mix phx.gen.secret
    UjkomPOS3FuoIz9Ssxvh4REJNlwfhCvJbpEVhInwhyOaCmAfRjXd43VwLf9zZ7bL
export SECRET_KEY_BASE=UjkomPOS3FuoIz9Ssxvh4REJNlwfhCvJbpEVhInwhyOaCmAfRjXd43VwLf9zZ7bL
