func IsHeight(arg string) bool

IsHeight returns true is the string a block height

func NewService

func NewService(k kv.DB, c *cache.Cache) *service

NewService instantiates a new Service layer for customer

func Routes

func Routes(g *echo.Group, s Service)

Routes mounts all /block, /blocks and /block-height based routes on the main group

	Previousblockhash string    `json:"previousblockhash,omitempty"`
}

Block model defined by standard

type BlockOut

type BlockOut struct {
	Block
	Transactions []tx.Tx `json:"transactions"`
}

BlockOut enhanced model block with full transactions

type Service

type Service interface {
	StoreBlock(b *Block, txs []tx.Tx) (err error)
	ReadFromHeight(height int32) (block Block, err error)
	ReadHeight() (height int32, err error)
	GetFromHash(hash string) (Block, error)
	GetFromHeight(height int32) (*BlockOut, error)
	GetFromHashWithTxs(hash string) (*BlockOut, error)
	GetLast() (*BlockOut, error)
	GetFromHeightRange(height int32, first int) (blocks []BlockOut, err error)
	GetStored() (blocks []Block, err error)
	GetStoredList(from int32) (blocks map[string]interface{}, err error)
	Remove(block *Block) error
	RemoveLast() error
	GetStoredTxs() (transactions []string, err error)
	GetTxBlock(hash string) (block *BlockOut, err error)
	GetTxBlockHeight(hash string) (height int32, err error)
}

Service interface exports available methods for tx service
