Variables ¶
var ErrWorkOracleClosed = errors.New("work oracle has been closed")
ErrWorkOracleClosed is returned when calling a method on an already closed WorkOracle instance.
Functions ¶
func CommitmentBytes ¶ added in v0.2.2
CommitmentBytes returns the commitment bytes for the given Node ID and Commitment ATX ID.
Types ¶
type LazyScrypter ¶ added in v0.9.0
type LazyScrypter struct {
// contains filtered or unexported fields
}
Lazy initialized Scrypter.
func (*LazyScrypter) Close ¶ added in v0.9.0
func (l *LazyScrypter) Close() error
func (*LazyScrypter) Positions ¶ added in v0.9.0
func (l *LazyScrypter) Positions(start, end uint64) (postrs.ScryptPositionsResult, error)
type OptionFunc ¶ added in v0.2.2
type OptionFunc func(*option) error
OptionFunc is a function that sets an option for a WorkOracle instance.
func WithCommitment ¶ added in v0.2.2
func WithCommitment(commitment []byte) OptionFunc
WithCommitment sets the commitment to use for the oracle.
func WithLogger ¶ added in v0.6.3
func WithLogger(logger *zap.Logger) OptionFunc
WithLogger sets the logger to use.
func WithMaxRetries ¶ added in v0.8.3
func WithMaxRetries(maxRetries int) OptionFunc
WithMaxRetries sets the maximum number of retries for a single initialization invocation.
func WithProviderID ¶ added in v0.6.0
func WithProviderID(id *uint32) OptionFunc
WithProviderID sets the ID of the OpenCL provider to use.
func WithRetryDelay ¶ added in v0.8.3
func WithRetryDelay(retryDelay time.Duration) OptionFunc
WithRetryDelay sets the delay between retries for a single initialization invocation.
func WithScryptParams ¶ added in v0.5.1
func WithScryptParams(params config.ScryptParams) OptionFunc
WithScryptParams sets the parameters for the scrypt algorithm. At the moment only configuring N is supported. r and p are fixed at 1 (due to limitations in the OpenCL implementation).
func WithVRFDifficulty ¶ added in v0.6.0
func WithVRFDifficulty(difficulty []byte) OptionFunc
WithVRFDifficulty sets the difficulty for the VRF Nonce. It is used as a PoW to make creating identities expensive and thereby prevent Sybil attacks.
type WorkOracle ¶
type WorkOracle struct {
// contains filtered or unexported fields
}
WorkOracle is a service that can compute labels for a given Node ID and CommitmentATX ID.
func New ¶ added in v0.6.2
func New(opts ...OptionFunc) (*WorkOracle, error)
New returns a WorkOracle. If not specified, the labels are computed using the default (CPU) provider.
func (*WorkOracle) Position ¶ added in v0.6.2
func (w *WorkOracle) Position(p uint64) (WorkOracleResult, error)
Position computes the label for a given position.
func (*WorkOracle) Positions ¶ added in v0.6.2
func (w *WorkOracle) Positions(start, end uint64) (WorkOracleResult, error)
Positions computes the labels for a given range of positions.
type WorkOracleResult ¶ added in v0.2.2
type WorkOracleResult struct {
Output []byte // Output are the computed labels
Nonce *uint64 // Nonce is the nonce of the proof of work
}
WorkOracleResult is the result of a call to WorkOracle. It contains the computed labels and a nonce for a proof of work.
