* update libp2p to 0.52.0 * proto name now must implement `AsRef<str>` * update libp2p version everywhere * ToSwarm, FromBehaviour, ToBehaviour also LocalProtocolsChange and RemoteProtocolsChange * new NetworkBehaviour invariants * replace `Vec<u8>` with `StreamProtocol` * rename ConnectionHandlerEvent::Custom to NotifyBehaviour * remove DialError & ListenError invariants also fix pending_events * use connection_limits::Behaviour See https://github.com/libp2p/rust-libp2p/pull/3885 * impl `void::Void` for `BehaviourOut` also use `Behaviour::with_codec` * KademliaHandler no longer public * fix StreamProtocol construction * update libp2p-identify to 0.2.0 * remove non-existing methods from PollParameters rename ConnectionHandlerUpgrErr to StreamUpgradeError * `P2p` now contains `PeerId`, not `Multihash` * use multihash-codetable crate * update Cargo.lock * reformat text * comment out tests for now * remove `.into()` from P2p * confirm observed addr manually See https://github.com/libp2p/rust-libp2p/blob/master/protocols/identify/CHANGELOG.md#0430 * remove SwarmEvent::Banned since we're not using `ban_peer_id`, this can be safely removed. we may want to introduce `libp2p::allow_block_list` module in the future. * fix imports * replace `libp2p` with smaller deps in network-gossip * bring back tests * finish rewriting tests * uncomment handler tests * Revert "uncomment handler tests" This reverts commit 720a06815887f4e10767c62b58864a7ec3a48e50. * add a fixme * update Cargo.lock * remove extra From * make void uninhabited * fix discovery test * use autonat protocols confirming external addresses manually is unsafe in open networks * fix SyncNotificationsClogged invariant * only set server mode manually in tests doubt that we need to set it on node since we're adding public addresses * address @dmitry-markin comments * remove autonat * removed unused var * fix EOL * update smallvec and sha2 in attempt to compile polkadot * bump k256 in attempt to build cumulus --------- Co-authored-by: parity-processbot <>
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
