Types

type Block

type Block struct {
	Version    uint32   // Block version, based on the software version creating this block.
	PrevBlock  [32]byte // The hash value of the previous block this particular block references.
	MerkleRoot [32]byte // Merkle tree hash of all transactions related to this block.
	Timestamp  uint32   // A timestamp recording when this block was created (limited to 2106).
	Bits       [4]byte  // The calculated difficulty target being used for this block.
	Nonce      [4]byte  // The nonce used to generate this block.
}

Block represents a Bitcoin block header, the metadata of a block.

func (*Block) Difficulty

func (b *Block) Difficulty() *big.Int

Difficulty returns the block (current mining) difficulty based on the bits. Difficulty is simply a human interpretable form of the target. The difficulty of the genesis block is 1. The formula is as follows:

difficulty = (target of lowest difficulty) / (current target)

func (*Block) Id

func (b *Block) Id() string

func (*Block) Marshal

func (b *Block) Marshal() [80]byte

func (*Block) Target

func (b *Block) Target() *big.Int

Target returns the PoW target based on the bits.

func (*Block) Unmarshal

func (b *Block) Unmarshal(r io.Reader) *Block

func (*Block) VerifyPoW

func (b *Block) VerifyPoW() bool

VerifyPoW returns whether this block satisfies the PoW.
