Constants ¶
const ( MethodSend = abi.MethodNum(0) MethodConstructor = abi.MethodNum(1) UniversalReceiverHookMethodNum = abi.MethodNum(3726118371) )
const DefaultHamtBitwidth = 5
Default log2 of branching factor for HAMTs. This value has been empirically chosen, but the optimal value for maps with different mutation profiles may differ.
const DefaultTokenActorBitwidth = 3
const EpochDurationSeconds = 30
PARAM_SPEC The duration of a chain epoch. Motivation: It guarantees that a block is propagated and WinningPoSt can be successfully done in time all supported miners. Usage: It is used for deriving epoch-denominated periods that are more naturally expressed in clock time. TODO: In lieu of a real configuration mechanism for this value, we'd like to make it a var so that implementations can override it at runtime. Doing so requires changing all the static references to it in this repo to go through late-binding function calls, or they'll see the "wrong" value. https://github.com/filecoin-project/specs-actors/issues/353 If EpochDurationSeconds is changed, update `BaselineExponent`, `lambda`, and // `expLamSubOne` in ./reward/reward_logic.go You can re-calculate these constants by changing the epoch duration in ./reward/reward_calc.py and running it.
const EpochsIn540Days = stabi.ChainEpoch(540 * EpochsInDay)
For V1 Stacked DRG sectors, the max is 540 days since Network Version 11
according to https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0014.md
const EpochsInDay = 24 * EpochsInHour
const EpochsInFiveYears = stabi.ChainEpoch(5 * EpochsInYear)
For V1_1 Stacked DRG sectors, the max is 5 years
const EpochsInHour = SecondsInHour / EpochDurationSeconds
const EpochsInYear = 365 * EpochsInDay
const FirstNonSingletonActorId = 100
const SecondsInDay = 24 * SecondsInHour
const SecondsInHour = 60 * 60
const SectorQualityPrecision = 20
Precision used for making QA power calculations

Functions ¶
func ConsensusMinerMinPower ¶
func ConsensusMinerMinPower(p stabi.RegisteredPoStProof) (stabi.StoragePower, error)
The minimum power of an individual miner to meet the threshold for leader election (in bytes). Motivation: - Limits sybil generation - Improves consensus fault detection - Guarantees a minimum fee for consensus faults - Ensures that a specific soundness for the power table Note: We may be able to reduce this in the future, addressing consensus faults with more complicated penalties, sybil generation with crypto-economic mechanism, and PoSt soundness by increasing the challenges for small miners.
func PoStProofWindowPoStPartitionSectors ¶
func PoStProofWindowPoStPartitionSectors(p stabi.RegisteredPoStProof) (uint64, error)
Returns the partition size, in sectors, associated with a Window PoSt proof type. The partition size is the number of sectors proved in a single PoSt proof.

func QuantizeUp(e abi.ChainEpoch, unit abi.ChainEpoch, offsetSeed abi.ChainEpoch) abi.ChainEpoch

This function is equivalent to `unit * ceil(e - (offsetSeed % unit) / unit) + (offsetSeed % unit)` with the variables/operations are over real numbers instead of ints. Precondition: unit >= 0 else behaviour is undefined
