Modules

runtime_api

Runtime API module declares the trait ParachainHost which is part of the Runtime API exposed from the Runtime to the Host.

v9

V9 Primitives.

vstaging

Staging Primitives.

Structs

BlakeTwo256

Blake2-256 Hash implementation.

CandidateHash

Unit type wrapper around Hash that represents a candidate hash.

HeadData

Parachain head data included in the chain.

HrmpChannelId

A type that uniquely identifies an HRMP channel. An HRMP channel is established between two paras. In text, we use the notation (A, B) to specify a channel between A and B. The channels are unidirectional, meaning that (A, B) and (B, A) refer to different channels. The convention is that we use the first item tuple for the sender and the second for the recipient. Only one channel is allowed between two participants in one direction, i.e. there cannot be 2 different channels identified by (A, B). A channel with the same para id in sender and recipient is invalid. That is, however, not enforced.

Id

Unique identifier of a parachain.

InboundDownwardMessage

A wrapped version of DownwardMessage. The difference is that it has attached the block number when the message was sent.

InboundHrmpMessage

An HRMP message seen from the perspective of a recipient.

OutboundHrmpMessage

An HRMP message seen from the perspective of a sender.

Slot

Unit type wrapper that represents a slot.

ValidationCode

Parachain validation code.

ValidationCodeHash

Unit type wrapper around Hash that represents the blake2-256 hash of validation code in particular.

Constants

LOWEST_PUBLIC_ID

The ID of the first publicly registrable parachain.

Traits

AppVerify

Means of signature verification of an application key.

HashT

Abstraction around hashing

Type Aliases

AccountId

Alias to the opaque account ID type for this chain, actually a AccountId32. This is always 32 bytes.

AccountIndex

The type for looking up accounts. We don’t expect more than 4 billion of them.

AccountPublic

Alias to the public key used for this chain, actually a MultiSigner. Like the signature, this also isn’t a fixed size when encoded, as different cryptos have different size public keys.

AuthorityDiscoveryId

An authority discovery authority identifier.

Balance

The balance of an account. 128-bits (or 38 significant decimal figures) will allow for 10 m currency (10^7) at a resolution to all for one second’s worth of an annualised 50% reward be paid to a unit holder (10^11 unit denomination), or 10^18 total atomic units, to grow at 50%/year for 51 years (10^9 multiplier) for an eventual total of 10^27 units (27 significant decimal figures). We round denomination to 10^12 (12 SDF), and leave the other redundancy at the upper end so that 32 bits may be multiplied with a balance in 128 bits without worrying about overflow.

Block

Block type.

BlockId

Block ID.

BlockNumber

The block number type used by Polkadot. 32-bits will allow for 136 years of blocks assuming 1 block per second.

DownwardMessage

A message sent from the relay-chain down to a parachain.

Hash

A hash of some data used by the relay chain.

Header

Header type.

HorizontalMessages

Moment

An instant or duration in time.

Nonce

Index of a transaction in the relay chain. 32-bit should be plenty.

SessionIndex

Simple index type with which we can count sessions.

Signature

Alias to type for a signature for a transaction on the relay chain. This allows one of several kinds of underlying crypto to be used, so isn’t a fixed size when encoded.

UpwardMessage

A message from a parachain to its Relay Chain.
