Types ¶
type ElkremNode ¶
type ElkremNode struct {
// contains filtered or unexported fields
}
You can calculate h from i but I can't figure out how without taking O(i) ops. Feels like there should be a clever O(h) way. 1 byte, whatever.
type ElkremReceiver ¶
type ElkremReceiver struct {
// contains filtered or unexported fields
}
func ElkremReceiverFromBytes ¶
func ElkremReceiverFromBytes(b []byte) (*ElkremReceiver, error)
func (*ElkremReceiver) AddNext ¶
func (e *ElkremReceiver) AddNext(sha *wire.ShaHash) error
AddNext inserts the next hash in the tree. Returns an error if the incoming hash doesn't fit.
func (*ElkremReceiver) AtIndex ¶
func (e *ElkremReceiver) AtIndex(w uint64) (*wire.ShaHash, error)
AtIndex returns the w'th hash in the receiver.
func (*ElkremReceiver) ToBytes ¶
func (e *ElkremReceiver) ToBytes() ([]byte, error)
ToBytes turns the Elkrem Receiver into a bunch of bytes in a slice. first the number of nodes (1 byte), then a series of 41 byte long serialized nodes, which are 1 byte height, 8 byte index, 32 byte hash.
func (*ElkremReceiver) UpTo ¶
func (e *ElkremReceiver) UpTo() uint64
UpTo tells you what the receiver can go up to.
type ElkremSender ¶
type ElkremSender struct {
// contains filtered or unexported fields
}
func NewElkremSender ¶
func NewElkremSender(r wire.ShaHash) *ElkremSender
Creates an Elkrem Sender from a root hash.
func (*ElkremSender) AtIndex ¶
func (e *ElkremSender) AtIndex(w uint64) (*wire.ShaHash, error)
AtIndex skips to the requested index should never error; remove error..?
func (*ElkremSender) ToBytes ¶
func (e *ElkremSender) ToBytes() []byte
ToBytes returns the root of the elkrem sender tree as a byte slice. This function is in place to allow one to export the root of the tree. However, node that if one uses a deterministic procedure to generate the root, then serialization isn't necessary as it can simply be re-derived on the fly.
