Moved from: https://github.com/paritytech/polkadot/pull/6951 closes https://github.com/paritytech/polkadot-sdk/issues/490 - [x] update cumulus --- This PR introduces transactional processing of certain xcm instructions. For the list of instructions checkout https://github.com/paritytech/polkadot-sdk/issues/490. The transactional processing is implemented as an xcm-executor config item. The two implementations in this PR are `FrameTransactionalProcessor` and `()`. The `()` implementation does no transactional processing. Each implementation of the `ProcessTransaction` trait has an `IS_TRANSACTIONAL` const that tells the XCVM if transactional processing is actually implemented. If Transactional processing is implemented, changes to touched registers should also be rolled back to prevent inconsistencies. Note for reviewers: Check out the following safety assumption: https://github.com/paritytech/polkadot-sdk/pull/1222/files#diff-4effad7d8c1c9de19fd27e18661cbf2128c8718f3b2420a27d2f816e0749ea53R30 --------- Co-authored-by: Keith Yeung <kungfukeith11@gmail.com> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: command-bot <>
Substrate Cumulus Parachain Template
A new Cumulus-based Substrate node, ready for hacking ☁️..
This project is originally a fork of the Substrate Node Template modified to include dependencies required for registering this node as a parathread or parachain to a relay chain.
The stand-alone version of this template is hosted on the Substrate Devhub Parachain Template for each release of Polkadot. It is generated directly to the upstream Parachain Template in Cumulus at each release branch using the Substrate Template Generator.
👉 Learn more about parachains here, and parathreads here.
🧙 Learn about how to use this template and run your own parachain testnet for it in the Devhub Cumulus Tutorial.
