Expand description

A single item in a path to describe the relative location of a consensus system.

Each item assumes a pre-existing location as its context and is defined in terms of it.

Variants§

§

Parachain(u32)

An indexed parachain belonging to and operated by the context.

Generally used when the context is a Polkadot Relay-chain.

§

AccountId32

Fields

§id: [u8; 32]

A 32-byte identifier for an account of a specific network that is respected as a sovereign endpoint within the context.

Generally used when the context is a Substrate-based chain.

§

AccountIndex64

Fields

§index: u64

An 8-byte index for an account of a specific network that is respected as a sovereign endpoint within the context.

May be used when the context is a Frame-based chain and includes e.g. an indices pallet.

§

AccountKey20

Fields

§key: [u8; 20]

A 20-byte identifier for an account of a specific network that is respected as a sovereign endpoint within the context.

May be used when the context is an Ethereum or Bitcoin chain or smart-contract.

§

PalletInstance(u8)

An instanced, indexed pallet that forms a constituent part of the context.

Generally used when the context is a Frame-based chain.

§

GeneralIndex(u128)

A non-descript index within the context location.

Usage will vary widely owing to its generality.

NOTE: Try to avoid using this and instead use a more specific item.

§

GeneralKey

Fields

§length: u8
§data: [u8; 32]

A nondescript array datum, 32 bytes, acting as a key within the context location.

Usage will vary widely owing to its generality.

NOTE: Try to avoid using this and instead use a more specific item.

§

OnlyChild

The unambiguous child.

Not currently used except as a fallback when deriving context.

§

Plurality

Fields

A pluralistic body existing within consensus.

Typical to be used to represent a governance origin of a chain, but could in principle be used to represent things such as multisigs also.

§

GlobalConsensus(NetworkId)

A global network capable of externalizing its own consensus. This is not generally meaningful outside of the universal level.
