Functions

func NewPool

func NewPool(server string) *redis.Pool

Types

type BlockChain

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

Blockchain is an interface to be used by the devp2p downloader to abstract the Redis DB

func LoadBlockChain

func LoadBlockChain(dbPool *redis.Pool) *BlockChain

func (*BlockChain) CurrentHeader

func (b *BlockChain) CurrentHeader() *types.Header

CurrentHeader retrieves the head header from the local chain.

func (*BlockChain) GetHeaderByHash

func (b *BlockChain) GetHeaderByHash(hash common.Hash) *types.Header

GetHeaderByHash retrieves a header from the local chain.

func (*BlockChain) GetTd

func (b *BlockChain) GetTd(hash common.Hash, number uint64) *big.Int

GetTd returns the total difficulty of a local block.

func (*BlockChain) HasHeader

func (b *BlockChain) HasHeader(desiredHash common.Hash, desiredHashNumber uint64) bool

HasHeader verifies a header's presence in the local chain (i.e. CHT)

func (*BlockChain) InsertHeaderChain

func (b *BlockChain) InsertHeaderChain(headers []*types.Header, checkFreq int) (int, error)

InsertHeaderChain inserts a batch of headers into the local chain.
