func (Witness) GetLatestSTH 

func (w Witness) GetLatestSTH(ctx context.Context, logID string) ([]byte, error)

GetLatestSTH returns a recent STH from the witness for the specified log ID.

func (Witness) Update 

func (w Witness) Update(ctx context.Context, logID string, sth []byte, proof [][]byte) ([]byte, error)
