Module 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

Modules

parachains

Primitives of polkadot-like chains, that are related to parachains functionality.

time_units

Human readable time units defined in terms of number of blocks.

Structs

AccountInfoStorageMapKeyProvider

Provides a storage key for account data.

BlockLength

All Polkadot-like chains have maximal block size set to 5MB.

BlockWeights

All Polkadot-like chains have the same block weights.

ExtrinsicBaseWeight

Weight of executing a NO-OP extrinsic, for example System::remark. Calculated by multiplying the Average with 1.0 and adding 0.

Kusama

Kusama Chain

Perbill

A fixed point representation of a number in the range [0, 1].

Constants

AVERAGE_HEADER_SIZE

Average header size in votes_ancestries field of justification on Polkadot-like chains.

AVERAGE_ON_INITIALIZE_RATIO

All Polkadot-like chains assume that an on-initialize consumes 1 percent of the weight on average, hence a single extrinsic will not be allowed to consume more than AvailableBlockRatio - 1 percent.

BEST_FINALIZED_KUSAMA_HEADER_METHOD

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

DAYS

A day, expressed in Polkadot-like chain blocks.

EXTRA_STORAGE_PROOF_SIZE

Number of extra bytes (excluding size of storage value itself) of storage proof, built at Polkadot-like chain. This mostly depends on number of entries in the storage trie. Some reserve is reserved to account future chain growth.

FREE_HEADERS_INTERVAL_FOR_KUSAMA_METHOD

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

HOURS

A hour, expressed in Polkadot-like chain blocks.

KUSAMA_SYNCED_HEADERS_GRANDPA_INFO_METHOD

Name of the <ThisChain>FinalityApi::accepted_<consensus>_finality_proofs runtime method.

MAXIMUM_BLOCK_WEIGHT

All Polkadot-like chains allow 2 seconds of compute with a 6-second average block time.

MAX_AUTHORITIES_COUNT

Maximal number of GRANDPA authorities at Polkadot-like chains.

MAX_MANDATORY_HEADER_SIZE

Approximate maximal header size on Polkadot-like chains.

MAX_MESSAGES_IN_DELIVERY_TRANSACTION

Maximal number of messages in single delivery transaction.

MAX_NESTED_PARACHAIN_HEAD_DATA_SIZE

Maximal size of encoded bp_parachains::ParaStoredHeaderData structure among all Polkadot parachains.

MILLISECS_PER_BLOCK

Milliseconds between Polkadot-like chain blocks.

MINUTES

A minute, expressed in Polkadot-like chain blocks.

PARAS_PALLET_NAME

Name of the parachains pallet in the Kusama runtime.

REASONABLE_HEADERS_IN_JUSTIFICATION_ANCESTRY

Reasonable number of headers in the votes_ancestries on Polkadot-like chains.

SLOT_DURATION

Slot duration in Polkadot-like chain consensus algorithms.

TX_EXTRA_BYTES

Maximal number of bytes, included in the signed Polkadot-like transaction apart from the encoded call itself.

WITH_KUSAMA_BRIDGE_PARACHAINS_PALLET_NAME

Name of the With-Kusama parachains pallet instance that is deployed at bridged chains.

WITH_KUSAMA_GRANDPA_PALLET_NAME

Name of the With-Kusama GRANDPA pallet instance that is deployed at bridged chains.

Traits

Convert

Infallible conversion trait. Generic over both source and destination types.

KusamaFinalityApi

API for querying information about the finalized chain headers.

Parameter

A type that can be used as a parameter in a dispatchable function.

SuffixedCommonTransactionExtensionExt

Helper trait to define some extra methods on SuffixedCommonTransactionExtension.
