Constants

View Source 
const AddressedPartitionsMax = 200

The maximum number of partitions that may be required to be loaded in a single invocation. This limits the number of simultaneous fault, recovery, or sector-extension declarations. With 48 deadlines (half-hour), 200 partitions per declaration permits loading a full EiB of 32GiB sectors with 1 message per epoch within a single half-hour deadline. A miner can of course submit more messages.

View Source 
const AddressedSectorsMax = 10_000

The maximum number of sector infos that may be required to be loaded in a single invocation.

View Source 
const ChainFinality = abi.ChainEpoch(900)

Epochs after which chain state is final.

View Source 
const DealLimitDenominator = 134217728

Ratio of sector size to maximum deals per sector. The maximum number of deals is the sector size divided by this number (2^27) which limits 32GiB sectors to 256 deals and 64GiB sectors to 512

View Source 
const ElectionLookback = abi.ChainEpoch(1) // PARAM_FINISH

Lookback from the current epoch for state view for leader elections.

View Source 
const FaultDeclarationCutoff = WPoStChallengeLookback + 50

Minimum period before a deadline's challenge window opens that a fault must be declared for that deadline. This lookback must not be less than WPoStChallengeLookback lest a malicious miner be able to selectively declare faults after learning the challenge value.

View Source 
const MaxSectorExpirationExtension = 540 * builtin.EpochsInDay

Maximum number of epochs past the current epoch a sector may be set to expire. The actual maximum extension will be the minimum of CurrEpoch + MaximumSectorExpirationExtension and sector.ActivationEpoch+sealProof.SectorMaximumLifetime()

View Source 
const MinSectorExpiration = 180 * builtin.EpochsInDay

Minimum number of epochs past the current epoch a sector may be set to expire.

View Source 
const NewSectorsPerPeriodMax = 128 << 10

The maximum number of new sectors that may be staged by a miner during a single proving period.

View Source 
const SectorsMax = 32 << 20 // PARAM_FINISH

The maximum number of sectors that a miner can have simultaneously active. This also bounds the number of faults that can be declared, etc. TODO raise this number, carefully https://github.com/filecoin-project/specs-actors/issues/470

View Source 
const TerminationLifetimeCap = abi.ChainEpoch(70)

Maximum number of days of BR a terminated sector can be penalized

View Source 
const WPoStChallengeLookback = abi.ChainEpoch(20)

Lookback from the deadline's challenge window opening from which to sample chain randomness for the challenge seed. This lookback exists so that deadline windows can be non-overlapping (which make the programming simpler) but without making the miner wait for chain stability before being able to start on PoSt computation. The challenge is available this many epochs before the window is actually open to receiving a PoSt.

View Source 
const WPoStPeriodDeadlines = uint64(48)

The number of non-overlapping PoSt deadlines in each proving period.

View Source 
const WorkerKeyChangeDelay = ChainFinality

Staging period for a miner worker key change. Finality is a harsh delay for a miner who has lost their worker key, as the miner will miss Window PoSts until it can be changed. It's the only safe value, though. We may implement a mitigation mechanism such as a second key or allowing the owner account to submit PoSts while a key change is pending.

Functions

func ExpectedRewardForPower added in v0.8.6 

func ExpectedRewardForPower(rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, qaSectorPower abi.StoragePower, projectionDuration abi.ChainEpoch) abi.TokenAmount

This is the BR(t) value of the given sector for the current epoch. It is the expected reward this sector would pay out over a one day period. BR(t) = CurrEpochReward(t) * SectorQualityAdjustedPower * EpochsInDay / TotalNetworkQualityAdjustedPower(t)

func FindSector added in v0.8.0 

func FindSector(store adt.Store, deadlines *Deadlines, sectorNum abi.SectorNumber) (uint64, uint64, error)

FindSector returns the deadline and partition index for a sector number. It returns an error if the sector number is not tracked by deadlines.

func InitialPledgeForPower added in v0.7.0 

func InitialPledgeForPower(qaPower abi.StoragePower, baselinePower abi.StoragePower, networkTotalPledge abi.TokenAmount, rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, networkCirculatingSupplySmoothed abi.TokenAmount) abi.TokenAmount

Computes the pledge requirement for committing new quality-adjusted power to the network, given the current total power, total pledge commitment, epoch block reward, and circulating token supply. In plain language, the pledge requirement is a multiple of the block reward expected to be earned by the newly-committed power, holding the per-epoch block reward constant (though in reality it will change over time).

func NewDeadlineInfo added in v0.5.1 

func NewDeadlineInfo(periodStart abi.ChainEpoch, deadlineIdx uint64, currEpoch abi.ChainEpoch) *dline.Info

Returns deadline-related calculations for a deadline in some proving period and the current epoch.

func PledgePenaltyForDeclaredFault added in v0.7.0 

func PledgePenaltyForDeclaredFault(rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, qaSectorPower abi.StoragePower,
	networkVersion network.Version) abi.TokenAmount

This is the FF(t) penalty for a sector expected to be in the fault state either because the fault was declared or because it has been previously detected by the network. FF(t) = DeclaredFaultFactor * BR(t)

func PledgePenaltyForTermination added in v0.7.2 

func PledgePenaltyForTermination(dayRewardAtActivation, twentyDayRewardAtActivation abi.TokenAmount, sectorAge abi.ChainEpoch,
	rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, qaSectorPower abi.StoragePower, networkVersion network.Version) abi.TokenAmount

Penalty to locked pledge collateral for the termination of a sector before scheduled expiry. SectorAge is the time between the sector's activation and termination.

func PledgePenaltyForUndeclaredFault added in v0.7.0 

func PledgePenaltyForUndeclaredFault(rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, qaSectorPower abi.StoragePower,
	networkVersion network.Version) abi.TokenAmount

This is the SP(t) penalty for a newly faulty sector that has not been declared. SP(t) = UndeclaredFaultFactor * BR(t)

func PreCommitDepositForPower added in v0.8.1 

func PreCommitDepositForPower(rewardEstimate, networkQAPowerEstimate *smoothing.FilterEstimate, qaSectorPower abi.StoragePower) abi.TokenAmount

Computes the PreCommit Deposit given sector qa weight and current network conditions. PreCommit Deposit = 20 * BR(t)

func QAPowerForSector added in v0.7.0 

func QAPowerForSector(size abi.SectorSize, sector *SectorOnChainInfo) abi.StoragePower

Returns the quality-adjusted power for a sector.

Returns the power for a sector size and weight.

func QualityForWeight added in v0.7.0 

func QualityForWeight(size abi.SectorSize, duration abi.ChainEpoch, dealWeight, verifiedWeight abi.DealWeight) abi.SectorQuality

DealWeight and VerifiedDealWeight are spacetime occupied by regular deals and verified deals in a sector. Sum of DealWeight and VerifiedDealWeight should be less than or equal to total SpaceTime of a sector. Sectors full of VerifiedDeals will have a SectorQuality of VerifiedDealWeightMultiplier/QualityBaseMultiplier. Sectors full of Deals will have a SectorQuality of DealWeightMultiplier/QualityBaseMultiplier. Sectors with neither will have a SectorQuality of QualityBaseMultiplier/QualityBaseMultiplier. SectorQuality of a sector is a weighted average of multipliers based on their propotions.

func RewardForConsensusSlashReport added in v0.7.0 

func RewardForConsensusSlashReport(elapsedEpoch abi.ChainEpoch, collateral abi.TokenAmount) abi.TokenAmount

func SectorKey 

func SectorKey(e abi.SectorNumber) abi.Keyer

Types

type Actor 

type Actor struct{}

func (Actor) AddLockedFund 

func (a Actor) AddLockedFund(rt Runtime, amountToLock *abi.TokenAmount) *abi.EmptyValue

Locks up some amount of the miner's unlocked balance (including funds received alongside the invoking message).

func (Actor) ChangeMultiaddrs added in v0.5.5 

func (a Actor) ChangeMultiaddrs(rt Runtime, params *ChangeMultiaddrsParams) *abi.EmptyValue

func (Actor) ChangePeerID 

func (a Actor) ChangePeerID(rt Runtime, params *ChangePeerIDParams) *abi.EmptyValue

func (Actor) ChangeWorkerAddress 

func (a Actor) ChangeWorkerAddress(rt Runtime, params *ChangeWorkerAddressParams) *abi.EmptyValue

ChangeWorkerAddress will ALWAYS overwrite the existing control addresses with the control addresses passed in the params. If a nil addresses slice is passed, the control addresses will be cleared. A worker change will be scheduled if the worker passed in the params is different from the existing worker.

func (Actor) CheckSectorProven 

func (a Actor) CheckSectorProven(rt Runtime, params *CheckSectorProvenParams) *abi.EmptyValue

func (Actor) Code added in v0.9.12 

func (a Actor) Code() cid.Cid

func (Actor) CompactPartitions added in v0.8.0 

func (a Actor) CompactPartitions(rt Runtime, params *CompactPartitionsParams) *abi.EmptyValue

Compacts a number of partitions at one deadline by removing terminated sectors, re-ordering the remaining sectors, and assigning them to new partitions so as to completely fill all but one partition with live sectors. The addressed partitions are removed from the deadline, and new ones appended. The final partition in the deadline is always included in the compaction, whether or not explicitly requested. Removed sectors are removed from state entirely. May not be invoked if the deadline has any un-processed early terminations.

func (Actor) CompactSectorNumbers added in v0.8.2 

func (a Actor) CompactSectorNumbers(rt Runtime, params *CompactSectorNumbersParams) *abi.EmptyValue

Compacts sector number allocations to reduce the size of the allocated sector number bitfield.

When allocating sector numbers sequentially, or in sequential groups, this bitfield should remain fairly small. However, if the bitfield grows large enough such that PreCommitSector fails (or becomes expensive), this method can be called to mask out (throw away) entire ranges of unused sector IDs. For example, if sectors 1-99 and 101-200 have been allocated, sector number 99 can be masked out to collapse these two ranges into one.

func (Actor) ConfirmSectorProofsValid added in v0.5.4 

func (a Actor) ConfirmSectorProofsValid(rt Runtime, params *builtin.ConfirmSectorProofsParams) *abi.EmptyValue

func (Actor) Constructor 

func (a Actor) Constructor(rt Runtime, params *ConstructorParams) *abi.EmptyValue

func (Actor) ControlAddresses 

func (a Actor) ControlAddresses(rt Runtime, _ *abi.EmptyValue) *GetControlAddressesReturn

func (Actor) DeclareFaults 

func (a Actor) DeclareFaults(rt Runtime, params *DeclareFaultsParams) *abi.EmptyValue

func (Actor) DeclareFaultsRecovered 

func (a Actor) DeclareFaultsRecovered(rt Runtime, params *DeclareFaultsRecoveredParams) *abi.EmptyValue

func (Actor) Exports 

func (a Actor) Exports() []interface{}

func (Actor) ExtendSectorExpiration 

func (a Actor) ExtendSectorExpiration(rt Runtime, params *ExtendSectorExpirationParams) *abi.EmptyValue

Changes the expiration epoch for a sector to a new, later one. The sector must not be terminated or faulty. The sector's power is recomputed for the new expiration.

func (Actor) OnDeferredCronEvent 

func (a Actor) OnDeferredCronEvent(rt Runtime, payload *CronEventPayload) *abi.EmptyValue

func (Actor) PreCommitSector 

func (a Actor) PreCommitSector(rt Runtime, params *SectorPreCommitInfo) *abi.EmptyValue

Proposals must be posted on chain via sma.PublishStorageDeals before PreCommitSector. Optimization: PreCommitSector could contain a list of deals that are not published yet.

func (Actor) ProveCommitSector 

func (a Actor) ProveCommitSector(rt Runtime, params *ProveCommitSectorParams) *abi.EmptyValue

Checks state of the corresponding sector pre-commitment, then schedules the proof to be verified in bulk by the power actor. If valid, the power actor will call ConfirmSectorProofsValid at the end of the same epoch as this message.

func (Actor) ReportConsensusFault 

func (a Actor) ReportConsensusFault(rt Runtime, params *ReportConsensusFaultParams) *abi.EmptyValue

func (Actor) State added in v0.9.12 

func (a Actor) State() cbor.Er

func (Actor) SubmitWindowedPoSt 

func (a Actor) SubmitWindowedPoSt(rt Runtime, params *SubmitWindowedPoStParams) *abi.EmptyValue

Invoked by miner's worker address to submit their fallback post

func (Actor) TerminateSectors 

func (a Actor) TerminateSectors(rt Runtime, params *TerminateSectorsParams) *TerminateSectorsReturn

Marks some sectors as terminated at the present epoch, earlier than their scheduled termination, and adds these sectors to the early termination queue. This method then processes up to AddressedSectorsMax sectors and AddressedPartitionsMax partitions from the early termination queue, terminating deals, paying fines, and returning pledge collateral. While sectors remain in this queue:

  1. The miner will be unable to withdraw funds.
  2. The chain will process up to AddressedSectorsMax sectors and AddressedPartitionsMax per epoch until the queue is empty.

The sectors are immediately ignored for Window PoSt proofs, and should be masked in the same way as faulty sectors. A miner terminating sectors in the current deadline must be careful to compute an appropriate Window PoSt proof for the sectors that will be active at the time the PoSt is submitted.

This function may be invoked with no new sectors to explicitly process the next batch of sectors.

func (Actor) WithdrawBalance 

func (a Actor) WithdrawBalance(rt Runtime, params *WithdrawBalanceParams) *abi.EmptyValue

type BigFrac struct {
	// contains filtered or unexported fields

	*adt.Array
	// contains filtered or unexported fields
}

func (BitfieldQueue) ForEach added in v0.8.0 

func (q BitfieldQueue) ForEach(cb func(epoch abi.ChainEpoch, bf bitfield.BitField) error) error

Iterates the queue.

func (BitfieldQueue) PopUntil added in v0.8.0

ExpirationSet is a collection of sector numbers that are expiring, either due to expected "on-time" expiration at the end of their life, or unexpected "early" termination due to being faulty for too long consecutively. Note that there is not a direct correspondence between on-time sectors and active power; a sector may be faulty but expiring on-time if it faults just prior to expected termination. Early sectors are always faulty, and active power always represents on-time sectors.

Balance of Miner Actor should be greater than or equal to the sum of PreCommitDeposits and LockedFunds. It is possible for balance to fall below the sum of PCD, LF and InitialPledgeRequirements, and this is a bad state (IP Debt) that limits a miner actor's behavior (i.e. no balance withdrawals) Excess balance as computed by st.GetAvailableBalance will be withdrawable or usable for pre-commit deposit or pledge lock-up.
