func (*Validator) NIPost added in v1.0.0 

func (v *Validator) NIPost(ctx context.Context, publishEpoch types.EpochID, nodeId types.NodeID, commitmentAtxId types.ATXID, nipost *types.NIPost, expectedChallenge types.Hash32, numUnits uint32, opts ...verifying.OptionFunc) (uint64, error)

NIPost validates a NIPost, given a node id and expected challenge. It returns an error if the NIPost is invalid.

Some of the Post metadata fields validation values is ought to eventually be derived from consensus instead of local configuration. If so, their validation should be removed to contextual validation, while still syntactically-validate them here according to locally configured min/max values.

func (*Validator) NIPostChallenge added in v1.0.0 

func (*Validator) NIPostChallenge(challenge *types.NIPostChallenge, atxs atxProvider, nodeID types.NodeID) error

func (*Validator) NumUnits added in v1.0.0 

func (*Validator) NumUnits(cfg *PostConfig, numUnits uint32) error

func (*Validator) PositioningAtx added in v1.0.0 

func (*Validator) PositioningAtx(id *types.ATXID, atxs atxProvider, goldenATXID types.ATXID, pubepoch types.EpochID, layersPerEpoch uint32) error

func (*Validator) Post added in v1.0.0 

func (v *Validator) Post(ctx context.Context, publishEpoch types.EpochID, nodeId types.NodeID, commitmentAtxId types.ATXID, PoST *types.Post, PostMetadata *types.PostMetadata, numUnits uint32, opts ...verifying.OptionFunc) error

Post validates a Proof of Space-Time (PoST). It returns nil if validation passed or an error indicating why validation failed.

func (*Validator) PostMetadata added in v1.0.0 

func (*Validator) PostMetadata(cfg *PostConfig, metadata *types.PostMetadata) error

func (*Validator) VRFNonce added in v1.0.0 

func (*Validator) VRFNonce(nodeId types.NodeID, commitmentAtxId types.ATXID, vrfNonce *types.VRFPostIndex, PostMetadata *types.PostMetadata, numUnits uint32) error
