Functions ¶

func CPUProviderID ¶

func CPUProviderID() int

func SaveMetadata(dir string, v *Metadata) error

func WithCommitment ¶ added in v0.2.0

func WithCommitment(commitment []byte) initializeOptionFunc

func WithConfig ¶ added in v0.2.0

func WithConfig(cfg Config) initializeOptionFunc

func WithInitOpts ¶ added in v0.2.0

func WithInitOpts(initOpts config.InitOpts) initializeOptionFunc

func WithLogger ¶ added in v0.2.0

func WithLogger(logger Logger) initializeOptionFunc

Types ¶

type ComputeProvider ¶

type ComputeProvider = gpu.ComputeProvider

func Providers ¶

func Providers() []ComputeProvider

type Config ¶

type Config = config.Config

type ConfigMismatchError ¶

type ConfigMismatchError = shared.ConfigMismatchError

type DiskState ¶

type DiskState struct {
	// contains filtered or unexported fields
}

func NewDiskState ¶

func NewDiskState(datadir string, bitsPerLabel uint) *DiskState

func (*DiskState) NumBytesWritten ¶

func (d *DiskState) NumBytesWritten() (uint64, error)

func (*DiskState) NumLabelsWritten ¶

func (d *DiskState) NumLabelsWritten() (uint64, error)

type InitOpts ¶

type InitOpts = config.InitOpts

type Initializer ¶

type Initializer struct {
	// contains filtered or unexported fields
}

func NewInitializer ¶

func NewInitializer(opts ...initializeOptionFunc) (*Initializer, error)

func (*Initializer) Initialize ¶

func (init *Initializer) Initialize(ctx context.Context) error

Initialize is the process in which the prover commits to store some data, by having its storage filled with pseudo-random data with respect to a specific id. This data is the result of a computationally-expensive operation.

func (*Initializer) Reset ¶

func (init *Initializer) Reset() error

func (*Initializer) SessionNumLabelsWritten ¶

func (init *Initializer) SessionNumLabelsWritten() uint64

func (*Initializer) Status ¶ added in v0.2.0

func (init *Initializer) Status() Status

type Logger ¶

type Logger = shared.Logger

type Metadata ¶

type Metadata struct {
	Commitment    []byte
	BitsPerLabel  uint8
	LabelsPerUnit uint64
	NumUnits      uint32
	NumFiles      uint32
}

metadata is the data associated with the PoST init procedure, persisted in the datadir next to the init files.

func LoadMetadata ¶

func LoadMetadata(dir string) (*Metadata, error)

type Proof ¶

type Proof = shared.Proof

type Status ¶ added in v0.2.0

type Status int

const (
	StatusNotStarted Status = iota
	StatusStarted
	StatusInitializing
	StatusCompleted
	StatusError
)
