Struct frame_system::pallet::config_preludes::SolochainDefaultConfig

pub struct SolochainDefaultConfig;

Default configurations of this pallet in a solochain environment.

Considerations:

By default, this type makes the following choices:

• Use a normal 32 byte account id, with a DefaultConfig::Lookup that implies no ‘account-indexing’ pallet is being used.
• Given that we don’t know anything about the existence of a currency system in scope, an DefaultConfig::AccountData is chosen that has no addition data. Overwrite this if you use pallet-balances or similar.
• Make sure to overwrite DefaultConfig::Version.
• 2s block time, and a default 5mb block size is used.

Trait Implementations

impl DefaultConfig for SolochainDefaultConfig

type Nonce = u32

The default type for storing how many extrinsics an account has signed.

type Hash = H256

The default type for hashing blocks and tries.

type Hashing = BlakeTwo256

The default hashing algorithm used.

type AccountId = AccountId32

The default identifier used to distinguish between accounts.

type Lookup = AccountIdLookup<<SolochainDefaultConfig as DefaultConfig>::AccountId, ()>

The lookup mechanism to get account ID from whatever is passed in dispatchers.

type MaxConsumers = ConstU32<128>

The maximum number of consumers allowed on a single account. Using 128 as default.

type AccountData = AccountInfo<<SolochainDefaultConfig as DefaultConfig>::Nonce, ()>

The default data to be stored in an account.

type OnNewAccount = ()

What to do if a new account is created.

type OnKilledAccount = ()

What to do if an account is fully reaped from the system.

type SystemWeightInfo = ()

Weight information for the extrinsics of this pallet.

type SS58Prefix = ()

This is used as an identifier of the chain.

type Version = ()

Version of the runtime.

type BlockWeights = ()

Block & extrinsics weights: base values and limits.

type BlockLength = ()

The maximum length of a block (in bytes).

type DbWeight = ()

The weight of database operations that the runtime can invoke.

type RuntimeEvent = ()

The ubiquitous event type injected by construct_runtime!.

type RuntimeOrigin = ()

The ubiquitous origin type injected by construct_runtime!.

type RuntimeCall = ()

The aggregated dispatch type available for extrinsics, injected by construct_runtime!.

type RuntimeTask = ()

The aggregated Task type, injected by construct_runtime!.

type PalletInfo = ()

Converts a module to the index of the module, injected by construct_runtime!.

type BaseCallFilter = Everything

The basic call filter to use in dispatchable. Supports everything as the default.

type BlockHashCount = TestBlockHashCount<ConstU32<256>>

Maximum number of block number to block hash mappings to keep (oldest pruned first). Using 256 as default.

type OnSetCode = ()

The set code logic, just the default since we’re not a parachain.

type SingleBlockMigrations = ()

All migrations that should run in the next runtime upgrade.

type MultiBlockMigrator = ()

The migrator that is used to run Multi-Block-Migrations.

type PreInherents = ()

A callback that executes in every block directly before all inherents were applied.

type PostInherents = ()

A callback that executes in every block directly after all inherents were applied.

type PostTransactions = ()

A callback that executes in every block directly after all transactions were applied.
