How to do runtime upgrade

  1. Compile calamari project.
git clone https://github.com/Manta-Network/Manta.git
cd Manta
git checkout manta-pc \\ now the branch is `add-calamari-runtime`
cargo build --release
  1. use manta-pc-launch to run a manta mini-system. If you want to know more, see https://github.com/Manta-Network/manta-pc-launch.
yarn start calamari.json
  1. Go to calamari runtime crate (Path /Manta/runtime/calamari/src/lib.rs), search the field spec_version: 1, and increase it by 1. Just like this,

spec_version: 2,

Runtime upgrade happens in the next block on parachain. You can see it in your block explorer.

This means that the runtime upgrade is ready. parachainSystem.ValidationFunctionStored means that the validationfunction data will be stored at this relaychain block. It will be change when relaychain is busy.

  • Runtime upgrade will be happened when validation function applied on relaychain. You will see this on parachain block explorer.

Waiting a moment and refresh the browser, you will see it:
