Expand description
The Moonbase Runtime.
Primary features of this runtime include:
- Ethereum compatibility
- Moonbase tokenomics
Modules§
- api
- asset_
config - Asset configuration for Moonbase.
- currency
- UNIT, the native token, uses 18 decimals of precision.
- genesis_
config_ preset - governance
- Governance configurations
- moonbase_
xcm_ weights - opaque
- Opaque types. These are used by the CLI to instantiate machinery that don’t need to know the specifics of the runtime. They can then be made to be agnostic over specific formats of data like extrinsics, allowing for them to continue syncing the network through upgrades to even the core data structures.
- runtime_
params - Dynamic runtime parameters for moonbase.
- xcm_
config - XCM configuration for Moonbase.
Macros§
Structs§
- Adjustment
Variable - The adjustment variable of the runtime. Higher values will cause
TargetBlockFullnessto change the fees more rapidly. This fast multiplier responds by doubling/halving in approximately one hour at extreme block congestion levels. - Babe
Data Getter - Block
GasLimit - Block
Length - We allow for 5 MB blocks.
- Block
Weights - TODO: this is left here so that
impl_runtime_apis_plus_commonwill find the same type forBlockWeightsin all runtimes. It can probably be removed once the customRuntimeBlockWeightshas been pushed to each runtime. - Deposit
Base - Deposit
Factor - Ethereum
XcmEnsure Proxy - Existential
Deposit - Find
Author Adapter - The author inherent provides an AccountId, but pallet evm needs an H160. This simple adapter makes the conversion for any types T, U such that T: Into
- GasLimit
PovSize Ratio - The amount of gas per pov. A ratio of 8 if we convert ref_time to gas and we compare
it with the pov_size for a block. E.g.
ceil(
(max_extrinsic.ref_time() / max_extrinsic.proof_size()) / WEIGHT_PER_GAS
)
We should re-check
xcm_config::Erc20XcmBridgeTransferGasLimitwhen changing this value - GasLimit
Storage Growth Ratio - The amount of gas per storage (in bytes): BLOCK_GAS_LIMIT / BLOCK_STORAGE_LIMIT (60_000_000 / 160 kb)
- Genesis
Account - Account definition used for genesis block construction.
- Inflation
Info - Initialization
Payment - Length
ToFee - Maintenance
Filter - Maintenance mode Call filter
- MaxAdditional
Fields - MaxRegistrars
- MaxService
Weight - MaxSignatories
- MaxSpend
Balance - MaxSub
Accounts - MaxSuffix
Length - MaxUsername
Length - Maximum
Multiplier - Maximum multiplier. We pick a value that is expensive but not impossibly so; it should act as a safety net.
- Minimum
Multiplier - Minimum amount of the multiplier. This value cannot be too low. A test case should ensure
that combined with
AdjustmentVariable, we can recover from the minimum. Seemultiplier_can_grow_from_zeroin integration_tests.rs. - NoPreimage

Constants§
- BLOCK_
STORAGE_ LIMIT - The highest amount of new storage that can be created in a block (160KB). Originally 40KB, then multiplied by 4 when the block deadline was increased from 500ms to 2000ms. Reference: https://github.com/moonbeam-foundation/moonbeam/blob/master/MBIPS/MBIP-5.md#specification
- DAYS
- EXTRINSIC_
BASE_ WEIGHT - FOREIGN_
ASSET_ PRECOMPILE_ ADDRESS_ PREFIX - The asset precompile address prefix. Addresses that match against this prefix will be routed to Erc20AssetsPrecompileSet being marked as foreign
- GAS_
PER_ SECOND - Current approximation of the gas/s consumption considering EVM execution over compiled WASM (on 4.4Ghz CPU). Given the 2 sec Weight, from which 75% only are used for transactions, the total EVM execution gas limit is: GAS_PER_SECOND * 2 * 0.75 ~= 60_000_000.
- HOURS
- MAXIMUM_
BLOCK_ WEIGHT - Maximum weight per block
- MAX_
POV_ SIZE - Maximum PoV size we support right now.
- MILLISECS_
PER_ BLOCK - MINUTES
- NORMAL_
WEIGHT - RUNTIME_
API_ VERSIONS - VERSION
- This runtime version. The spec_version is composed of 2x2 digits. The first 2 digits represent major changes that can’t be skipped, such as data migration upgrades. The last 2 digits represent minor changes which can be skipped.
- WASM_
BINARY - WASM_
BINARY_ BLOATY - WASM_
BINARY_ PATH - WEEKS
- WEIGHT_
PER_ GAS - Approximate ratio of the amount of Weight per Gas. u64 works for approximations because Weight is a very small unit compared to gas.
