Types

type Block

type Block struct {
	// header of this block.
	Header

	// Transactions of this block.
	Transactions []Transaction
}

Block represent a block that stored in the blockchain database.

type BlockHeader

type BlockHeader interface {
	Previous() common.Uint256
	Bits() uint32
	MerkleRoot() common.Uint256
	Hash() common.Uint256
	PowHash() common.Uint256
	Serialize(w io.Writer) error
	Deserialize(r io.Reader) error
}

type Filter

type Filter interface {
	Add(data []byte)
	Matches(data []byte) bool
}

type Header

type Header struct {
	// The origin header of the block
	BlockHeader

	Height uint32

	// MerkleProof for transactions packed in this block
	NumTxs uint32
	Hashes []*common.Uint256
	Flags  []byte

	// The total work from the genesis block to this
	// current block
	TotalWork *big.Int
}

Header is a data structure stored in database.

	Timestamp time.Time

	// Transaction
	RawData []byte
}

Tx is a data structure used in database.
