Functions

func CheckHeader

func CheckHeader(r io.ReadSeeker, height int64, p *chaincfg.Params) bool

CheckHeader ...

func CheckRange

func CheckRange(r io.ReadSeeker, first, last int64, p *chaincfg.Params) bool

CheckRange verifies a range of headers. It checks their proof of work, difficulty adjustments, and that they all link in to each other properly. This is the only blockchain technology in the whole code base. Returns false if anything bad happens. Returns true if the range checks out with no errors.

func MakeMerkleParent

func MakeMerkleParent(left *wire.ShaHash, right *wire.ShaHash) *wire.ShaHash

MakeMerkleParent ...
