Functions

func DeriveSha 

func DeriveSha(list DerivableList) common.Hash

func Number 

func Number(b1, b2 *Block) bool

func Sender 

func Sender(signer Signer, tx *Transaction) (common.Address, error)

Sender returns the address derived from the signature (V, R, S) using secp256k1 elliptic curve and an error if it failed deriving or upon an incorrect signature.

Sender may cache the address, allowing it to be used regardless of signing method. The cache is invalidated if the cached signer does not match the signer used in the current call.

Types

func (BlockBy) Sort 

func (self BlockBy) Sort(blocks Blocks)

type BlockNonce 

type BlockNonce [8]byte

func EncodeNonce(i uint64) BlockNonce

EncodeNonce converts the given integer to a block nonce.

func (BlockNonce) MarshalText 

func (n BlockNonce) MarshalText() ([]byte, error)

MarshalText encodes n as a hex string with 0x prefix.

func (n BlockNonce) Uint64() uint64

Uint64 returns the integer value of a block nonce.

func (*BlockNonce) UnmarshalText 

func (n *BlockNonce) UnmarshalText(input []byte) error

UnmarshalText implements encoding.TextUnmarshaler.

type Blocks 

type Blocks []*Block

type Body 

type Body struct {
	Transactions []*Transaction
}

Body is a simple (mutable, non-safe) data container for storing and moving a block's data contents (transactions) together.

type DerivableList 

type DerivableList interface {
	Len() int
	GetRlp(i int) []byte
}
type Header struct {
	ParentHash common.Hash    `json:"parentHash"       gencodec:"required"`
	Coinbase   common.Address `json:"miner"            gencodec:"required"`
	TxHash     common.Hash    `json:"transactionsRoot" gencodec:"required"`

	// Bloom       Bloom          `json:"logsBloom"        gencodec:"required"`
	Difficulty *big.Int   `json:"difficulty"       gencodec:"required"`
	Number     *big.Int   `json:"number"           gencodec:"required"`
	Time       *big.Int   `json:"timestamp"        gencodec:"required"`
	Extra      []byte     `json:"extraData"        gencodec:"required"`
	Nonce      BlockNonce `json:"nonce"            gencodec:"required"`

func (MasterSigner) SignatureValues 

func (fs MasterSigner) SignatureValues(tx *Transaction, sig []byte) (r, s, v *big.Int, err error)

type Signer 

type Signer interface {
	// Sender returns the sender address of the transaction.
	Sender(tx *Transaction) (common.Address, error)
	// SignatureValues returns the raw R, S, V values corresponding to the

	SignatureValues(tx *Transaction, sig []byte) (r, s, v *big.Int, err error)
	// Hash returns the hash to be signed.
	Hash(tx *Transaction) common.Hash
	// Equal returns true if the given signer is the same as the receiver.
	Equal(Signer) bool
}
