Functions

func CRC

func CRC(height uint64, packed []byte) uint64

crc a block digest

func DeleteDownToBlock

func DeleteDownToBlock(finalBlockNumber uint64) error

delete from current highest block down to and including the specified block

func DigestForBlock

func DigestForBlock(number uint64) (blockdigest.Digest, error)

func Finalise

func Finalise() error

shudown the block system

func Get

func Get() (blockdigest.Digest, uint64)

get block data for initialising a new block returns: previous block digest and the number for the new block

func GetHeight

func GetHeight() uint64

get the current height

func GetLatestCRC

func GetLatestCRC() uint64

fetch latest crc value

func GetPayment

func GetPayment(blockNumberKey []byte) *transactionrecord.Payment

get a payment record from a specific block given the blocks 8 byte big endian key

func Initialise

func Initialise() error

setup the current block data

func OwnerOf

func OwnerOf(txId merkle.Digest) *account.Account

find the owner of a specific transaction (only issue or transfer is allowed)

func StoreIncoming

func StoreIncoming(packedBlock []byte) error

store an incoming block checking to make sure it is valid first

func TransferOwnership

need to have a lock

func VerifyTransfer

func VerifyTransfer(arguments *transactionrecord.BitmarkTransfer) (merkle.Digest, []byte, *transactionrecord.BitmarkTransfer, []byte, error)

verify that a transfer is ok

Types

type Ownership

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

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

type RingReader

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

to iterate though the ring

func NewRingReader

func NewRingReader() *RingReader

start of ring iterator

func (*RingReader) Get

func (r *RingReader) Get() (uint64, bool)

fetch item from ring works in reverse, fetching older items
