Crate domain_runtime_primitives

Common primitives for subspace domain runtime.

Modules

• opaque
  Opaque types.

Structs

• AccountId20
  A fully Ethereum-compatible AccountId. Conforms to H160 address and ECDSA key standards. Alternative to H256->H160 mapping.
• AccountId20Converter
  An AccountId20 to MultiAccount converter.
• AccountIdConverter
  An AccountId32 to MultiAccount converter.
• CheckExtrinsicsValidityError
• DecodeExtrinsicError

Enums

• HoldIdentifier
• MultiAccountId
  MultiAccountId used by all the domains to describe their account type.

Constants

• CHECK_EXTRINSICS_AND_DO_PRE_DISPATCH_METHOD_NAME
  fullu qualified method name of check_extrinsics_and_do_pre_dispatch runtime api. Used to call state machine. Change it when the runtime api’s name is changed in the interface.
• ERR_BALANCE_OVERFLOW
  Custom error when balance overflow occurs.
• ERR_NONCE_OVERFLOW
  Custom error when nonce overflow occurs.
• EXISTENTIAL_DEPOSIT
  Computed as ED = Account data size * Price per byte, where Price per byte = Min Number of validators * Storage duration (years) * Storage cost per year Account data size (80 bytes) Min Number of redundant validators (10) - For a stable and redundant blockchain we need at least a certain number of full nodes/collators. Storage duration (1 year) - It is theoretically unlimited, accounts will stay around while the chain is alive. Storage cost per year of (12 * 1e-9 * 0.1 ) - SSD storage on cloud hosting costs about 0.1 USD per Gb per month
• NORMAL_DISPATCH_RATIO
  Dispatch ratio for domains
• SLOT_DURATION
  Slot duration that is same as consensus chain runtime.

Traits

• Signer
  Extracts the signer from an unchecked extrinsic.
• TryConvertBack
  Extensible conversion trait. Generic over both source and destination types.

Functions

• block_weights
• maximum_block_length
  Maximum block length for all dispatches. This is set to 3.75 MiB since consensus chain supports on 3.75 MiB for normal
• maximum_domain_block_weight
  The maximum domain block weight with 3.25 MiB as proof size Consensus allows 3.75 MiB but Fraud proof can carry extra size along with proof size So we set the proof size to 3.25 MiB

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.
• Address
  The address format for describing accounts.
• Balance
  Balance of an account.
• BlockNumber
  An index to a block.
• EVMChainId
  The EVM chain Id type
• Hash
  A hash of some data used by the chain.
• Nonce
  Index of a transaction in the chain.
• Signature
  Alias to 512-bit hash when used in the context of a transaction signature on the chain.
