Types

type Ownership

type Ownership struct {
	N          uint64                       `json:"n,string"`
	TxId       merkle.Digest                `json:"txId"`
	IssueTxId  merkle.Digest                `json:"issue"`

}

type to represent an ownership record

func ListBitmarksFor

func ListBitmarksFor(owner *account.Account, start uint64, count int) ([]Ownership, error)

fetch a list of bitmarks for an owner
