* Make grandpa work * Introduce `SharedData` * Add test and fix bugs * Switch to `SharedData` * Make grandpa tests working * More Babe work * Make it async * Fix fix * Use `async_trait` in sc-consensus-slots This makes the code a little bit easier to read and also expresses that there can always only be one call at a time to `on_slot`. * Make grandpa tests compile * More Babe tests work * Fix network test * Start fixing service test * Finish service-test * Fix sc-consensus-aura * Fix fix fix * More fixes * Make everything compile *yeah* * Fix build when we have Rust 1.51 * Update client/consensus/common/src/shared_data.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/common/src/shared_data.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/common/src/shared_data.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/common/src/shared_data.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/common/src/shared_data.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/babe/src/tests.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/babe/src/tests.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Fix warning Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com>
Substrate offchain workers.
The offchain workers is a special function of the runtime that gets executed after block is imported. During execution it's able to asynchronously submit extrinsics that will either be propagated to other nodes or added to the next block produced by the node as unsigned transactions.
Offchain workers can be used for computation-heavy tasks that are not feasible for execution during regular block processing. It can either be tasks that no consensus is required for, or some form of consensus over the data can be built on-chain for instance via:
- Challenge period for incorrect computations
- Majority voting for results
- etc
