Types

type Chain

type Chain struct {
	// contains filtered or unexported fields
}

Chain is an in memory blockchain used for testing

func NewChain

func NewChain(user key.Receiver) *Chain

NewChain returns a new block from the data and previous hash.

func (*Chain) Append

func (c *Chain) Append(blk *block.Block)

Append will append a block to the end of the chain

func (*Chain) Base

func (c *Chain) Base() (*block.Block, error)

Base returns the base of the chain

func (*Chain) BlockByIndex

func (c *Chain) BlockByIndex(i int) *block.Block

BlockByIndex indexes the underlying array of blocks

func (*Chain) Get

func (c *Chain) Get(h []byte) (*block.Block, error)

Get will get a block given it's hash

func (*Chain) Head
