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.

View Source 
const DefaultTokenActorBitwidth = 3
View Source 
const EndOfLifeClaimDropPeriod = 30 * EpochsInDay
View Source 
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

var TokenPrecision = big.NewIntUnsigned(1_000_000_000_000_000_000)

Number of token units in an abstract "FIL" token. The network works purely in the indivisible token amounts. This constant converts to a fixed decimal with more human-friendly scale.

var TotalFilecoin = big.Mul(big.NewIntUnsigned(2_000_000_000), TokenPrecision)

The maximum supply of Filecoin that will ever exist (in token units)

var VerifiedDealWeightMultiplier = big.NewInt(100)

Quality multiplier for verified deals in a sector

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 GenerateFRCMethodNum 

func GenerateFRCMethodNum(name string) (abi.MethodNum, error)

Generates a standard FRC-42 compliant method number Reference: https://github.com/filecoin-project/FIPs/blob/master/FRCs/frc-0042.md

func MakeEmptyState 

func MakeEmptyState() (cid.Cid, error)

func MustGenerateFRCMethodNum 

func MustGenerateFRCMethodNum(name string) abi.MethodNum

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 

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

Rounds e to the nearest exact multiple of the quantization unit offset by offsetSeed % unit, rounding up. 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

func SealProofSectorMaximumLifetime 

func SealProofSectorMaximumLifetime(p stabi.RegisteredSealProof) (stabi.ChainEpoch, error)

SectorMaximumLifetime is the maximum duration a sector sealed with this proof may exist between activation and expiration
