Crate bp_moonbeam

Moonbeam bridge primitives

Modules

bp_kusama

Bridging primitives describing the Kusama relay chain, which we need for the other side. Same approach as in https://github.com/polkadot-fellows/runtimes/pull/627

Structs

BlockLength

Size limit of the Cumulus-based bridge hub blocks.

BlockWeights

Weight limit of the Cumulus-based bridge hub blocks.

GlobalConsensusLocation

Moonbeam

Moonbeam parachain.

Constants

AVERAGE_BLOCK_INTERVAL

Average block time for Cumulus-based parachains

BEST_FINALIZED_MOONBEAM_POLKADOT_HEADER_METHOD

Name of the <ThisChain>FinalityApi::best_finalized runtime method.

FREE_HEADERS_INTERVAL_FOR_MOONBEAM_POLKADOT_METHOD

Name of the <ThisChain>FinalityApi::free_headers_interval runtime method.

FROM_MOONBEAM_POLKADOT_MESSAGE_DETAILS_METHOD

Name of the From<ThisChain>InboundLaneApi::message_details runtime method.

MAX_UNCONFIRMED_MESSAGES_IN_CONFIRMATION_TX

Maximal number of unconfirmed messages at inbound lane for Cumulus-based parachains. Note: this value is security-relevant, decreasing it should not be done without careful analysis (like the one above).

MAX_UNREWARDED_RELAYERS_IN_CONFIRMATION_TX

Maximal number of unrewarded relayer entries at inbound lane for Cumulus-based parachains. Note: this value is security-relevant, decreasing it should not be done without careful analysis (like the one above).

PARACHAIN_ID

Identifier of Moonbeam parachain in the Polkadot relay chain.

TO_MOONBEAM_POLKADOT_MESSAGE_DETAILS_METHOD

Name of the To<ThisChain>OutboundLaneApi::message_details runtime method.

WITH_MOONBEAM_POLKADOT_MESSAGES_PALLET_NAME

Name of the With-MoonbeamPolkadot messages pallet instance that is deployed at bridged chains.

Traits

FromMoonbeamPolkadotInboundLaneApi

Inbound message lane API for messages sent by this chain.

MoonbeamPolkadotFinalityApi

API for querying information about the finalized chain headers.

ToMoonbeamPolkadotOutboundLaneApi

Outbound message lane API for messages that are sent to this chain.

Type Aliases

AccountId

Some way of identifying an account on the chain. We intentionally make it equivalent to the public key of our transaction signing scheme.

Balance

Balance of an account.

BlockNumber

An index to a block.

Hash

A hash of some data used by the chain.

Hasher

The type of object that can produce hashes on Polkadot-like chains.

Header

Block header type as expected by this runtime.

LaneId

Bridge lane identifier.

Nonce

Nonce of a transaction on the Polkadot-like chains.

Signature

Alias to 512-bit hash when used in the context of a transaction signature on the chain.

SignedBlock

Polkadot-like block signed with a Justification.
