    Compile the runtime with srtool

    When voting for a runtime upgrade, you should check that the proposed hash actually corresponds to the published code you reviewed. Otherwise, a malicious runtime upgrade could be advertised as a legitimate one.

    mkdir runtime/gdev/target
    chmod o+w runtime/gdev/target
    # Workaround see !239
    echo -e "[toolchain]\nchannel = \"1.81.0\"\ncomponents = [ \"rust-std\", \"rust-src\" ]" > runtime/gdev/rust-toolchain.toml
    docker run \
      -i \
      --rm \
      -e PACKAGE=gdev-runtime \
      -e RUNTIME_DIR=runtime/gdev \
      -v $PWD:/build \
      paritytech/srtool:1.81.0-0.17.0 build --app --json -cM

    Then, the runtime wasm bytecode is generated in this location:

    runtime/gdev/target/srtool/release/wbuild/gdev-runtime/gdev_runtime.compact.compressed.wasm

    To compare it to last official :
