Functions ¶
func DeFountain ¶
DeFountain takes a []Block of valid blocks (validated by ValidateBlocks) and recompiles the blocks into the source file as an io.Reader. It optionally allows for dynamic reconstruction that has a higher success rate, but can increase overall runtime.
func Split ¶
Splits a 'file' into blocks of size 'block_size' and outputs them into The directory given by 'filedir'
func ValidateFlags ¶
Types ¶
type Block ¶
type Block struct {
Id string // unique Id of block
Parents []string // slice of parent chunks
Data string // encoded source data
Hash string // signed content hash
}
func Fountain ¶
Fountain takes an io.Reader from a source file and implements a Luby Transform fountain code encoding algorithm over the file. It uses degree of distribution, chunk size, and a percent of chunks to generate into blocks.
func ValidateBlocks ¶
ValidateBlocks takes a []Block of remotely pulled blocks from the network and compares it to a block chain generated list. Returns an empty list if all blocks are valid, or a []Block of corrupt blocks otherwise.
