Functions ¶

func ToHex ¶

func ToHex(num int64) []byte

ToHex converts a number to base 10 binary.

Types ¶

type Block ¶

type Block struct {
	Hash     []byte
	Data     []byte
	PrevHash []byte
	Nonce    int
}

Block is the struct for each block in the blockchain.

func CreateBlock ¶

func CreateBlock(data string, prevHash []byte) *Block

CreateBlock creates a new block in the blockchain.

func Deserialize ¶

func Deserialize(data []byte) *Block

Deserialize takes in encoded data and returns an un-encoded block.

func Genesis ¶

func Genesis() *Block

Genesis creates the blockchains first block.

func (*Block) Serialize ¶

func (b *Block) Serialize() []byte

Serialize encodes a block.

type Blockchain ¶

type Blockchain struct {
	LastHash []byte
	Database *badger.DB
}

Blockchain is a list of blocks in the blockchain.

func InitBlockchain ¶

func InitBlockchain() *Blockchain

InitBlockchain initializes the blockchain.

func (*Blockchain) AddBlock ¶

func (chain *Blockchain) AddBlock(data string)

AddBlock adds a block to the blockchain.

func (*Blockchain) Iterator ¶

func (chain *Blockchain) Iterator() *Iterator

Iterator converts a blockchain to a blockchain iterator.

type Iterator ¶

type Iterator struct {
	CurrentHash []byte
	Database    *badger.DB
}

Iterator is struct for the current iteration of the blockchain.

func (*Iterator) Next ¶

func (iter *Iterator) Next() *Block

Next gives you the "next" block, working backwards through the blockchain.

type ProofOfWork ¶

type ProofOfWork struct {
	Block  *Block
	Target *big.Int
}

ProofOfWork is the struct fot our proof of work algorithm.

func NewProof ¶

func NewProof(b *Block) *ProofOfWork

NewProof creates a new proof of work.

func (*ProofOfWork) InitData ¶

func (pow *ProofOfWork) InitData(nonce int) []byte

InitData initialized the data.

func (*ProofOfWork) Run ¶

func (pow *ProofOfWork) Run() (int, []byte)

Run initiates the proof of work algorithm.

func (*ProofOfWork) Validate ¶

func (pow *ProofOfWork) Validate() bool

Validate makes sure the proof of work is valid.
