const EpochDurationSeconds = 30

The duration of a chain epoch. This 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.

Functions

func ActorNameByCode 

func ActorNameByCode(code cid.Cid) string

ActorNameByCode returns the (string) name of the actor given a cid code.

func ConsensusMinerMinPower added in v0.9.4 

func ConsensusMinerMinPower(p stabi.RegisteredSealProof) (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 IsBuiltinActor 

func IsBuiltinActor(code cid.Cid) bool

IsBuiltinActor returns true if the code belongs to an actor defined in this repo.

func IsPrincipal 

func IsPrincipal(code cid.Cid) bool

Tests whether a code CID represents an actor that can be an external principal: i.e. an account or multisig. We could do something more sophisticated here: https://github.com/filecoin-project/specs-actors/issues/178

func PoStProofWindowPoStPartitionSectors added in v0.9.4 

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 RequestMinerControlAddrs 

func RequestMinerControlAddrs(rt runtime.Runtime, minerAddr addr.Address) (ownerAddr addr.Address, workerAddr addr.Address, controlAddrs []addr.Address)

func RequireNoErr 

func RequireNoErr(rt runtime.Runtime, err error, defaultExitCode exitcode.ExitCode, msg string, args ...interface{})

Aborts with a formatted message if err is not nil. The provided message will be suffixed by ": %s" and the provided args suffixed by the err.

func RequireParam added in v0.7.0 

func RequireParam(rt runtime.Runtime, predicate bool, msg string, args ...interface{})

Aborts with an ErrIllegalArgument if predicate is not true.

func RequireSuccess 

func RequireSuccess(rt runtime.Runtime, e exitcode.ExitCode, msg string, args ...interface{})

Propagates a failed send by aborting the current method with the same exit code.

func ResolveToIDAddr added in v0.9.2 

func ResolveToIDAddr(rt runtime.Runtime, address addr.Address) (addr.Address, error)

ResolveToIDAddr resolves the given address to it's ID address form. If an ID address for the given address dosen't exist yet, it tries to create one by sending a zero balance to the given address.

func SealProofSectorMaximumLifetime added in v0.9.4 

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

func SealProofWindowPoStPartitionSectors added in v0.9.4 

func SealProofWindowPoStPartitionSectors(p stabi.RegisteredSealProof) (uint64, error)

Returns the partition size, in sectors, associated with a seal proof type. The partition size is the number of sectors proved in a single PoSt proof.

type ConfirmSectorProofsParams added in v0.5.4 

type ConfirmSectorProofsParams struct {
	Sectors []abi.SectorNumber
}

func (*ConfirmSectorProofsParams) MarshalCBOR added in v0.5.4 

func (t *ConfirmSectorProofsParams) MarshalCBOR(w io.Writer) error

func (*ConfirmSectorProofsParams) UnmarshalCBOR added in v0.5.4 

func (t *ConfirmSectorProofsParams) UnmarshalCBOR(r io.Reader) error

type Discard added in v0.9.9 

type Discard struct{}

Discard is a helper

func (*Discard) MarshalCBOR added in v0.9.9 

func (d *Discard) MarshalCBOR(_ io.Writer) error

func (*Discard) UnmarshalCBOR added in v0.9.9 

func (d *Discard) UnmarshalCBOR(_ io.Reader) error

type MinerAddrs 

type MinerAddrs struct {
	Owner        addr.Address
	Worker       addr.Address
	ControlAddrs []addr.Address
}

This type duplicates the Miner.ControlAddresses return type, to work around a circular dependency between actors.

func (*MinerAddrs) MarshalCBOR 

func (t *MinerAddrs) MarshalCBOR(w io.Writer) error

func (*MinerAddrs) UnmarshalCBOR 

func (t *MinerAddrs) UnmarshalCBOR(r io.Reader) error

type PoStProofPolicy added in v0.9.13 

type PoStProofPolicy struct {
	WindowPoStPartitionSectors uint64
}

Policy values associated with a PoSt proof type.

type SealProofPolicy added in v0.9.4 

type SealProofPolicy struct {
	SectorMaxLifetime      stabi.ChainEpoch
	ConsensusMinerMinPower stabi.StoragePower
}

Policy values associated with a seal proof type.
