func New ¶

func New() *HyperShaChain

NewHyperShaChain

used to track their pre-images

func NewFromSeed ¶

func NewFromSeed(seed *[32]byte, deriveTo uint64) (*HyperShaChain, error)

NewHyperShaChainFromSeed...

used to derive your own pre-images

func (*HyperShaChain) AddNextHash ¶

func (h *HyperShaChain) AddNextHash(hash [32]byte) error

addHash

func (*HyperShaChain) CurrentPreImage ¶

func (h *HyperShaChain) CurrentPreImage() *wire.ShaHash

CurrentPreImage...

func (*HyperShaChain) CurrentRevocationHash ¶

func (h *HyperShaChain) CurrentRevocationHash() []byte

CurrentRevocationHash... TODO(roasbeef): *wire.ShaHash vs [wire.HashSize]byte ?

func (*HyperShaChain) Decode ¶

UnmarshallBinary...

func (*HyperShaChain) Encode ¶

func (h *HyperShaChain) Encode(b io.Writer) error

MarshallBinary...

func (*HyperShaChain) GetHash ¶

func (h *HyperShaChain) GetHash(index uint64) (*[32]byte, error)

getHash... index should be commitment #

func (*HyperShaChain) LocatePreImage ¶

func (h *HyperShaChain) LocatePreImage(outputScript []byte) (uint64, *[32]byte)

LocatePreImage... Alice just broadcasted an old commitment tx, we need the revocation hash to claim the funds so we don't get cheated. However, we aren't storing all the pre-images in memory. So which shachain index # did she broadcast?
