EthereumTraders Get Burned In Ethereum Flash CrashJeff John RobertsThe white hot cryptocurrency Ethereum went on a wild ride on Wednesday, plummeting from around $320 to around 10 cents in a so-called "flash crash."The price soon recovered but not before some investors took a terrible bath and some others made out like bandits.Ethereum, a popular new digital currency, trades on exchanges much like its older rival bitcoin.bitcoin kyle powersThe most widely-used exchange, Coinbase-owned GDAX, operates like a traditional stock exchange, and lets traders buy stock on margin and place so-called "stop loss" orders—an automated instruction to sell if the price falls below a certain point.As Adam White, the VP of GDAX, explained in a blog post, one investor placed a multi-million dollar Ethereum "sell" order at 12:30 p.m.litecoin low

The size of the order caused the price of the currency, which is already volatile, to dip.Things started to go really haywire, however, as the price dip triggered a series of stop loss orders."Thisslippage started a cascade of approximately 800 stop loss orders and margin funding liquidations, causing ETH to temporarily trade as low as $0.10," White explained.voice assistantsGoogle Home Outsmarts Amazon Alexa in 3,000 Question QuizBitcoinBitcoin and Ethereum Just Crashed, Taking Coinbase Down With ThemEthereumThis Cryptocurrency Hit a Record High—And It’s Not BitcoinBitcoinBitcoin Breaks $3,000, Continuing Epic Bull RunBlockchainSpeculators Are Driving a Cryptocoin BubbleBitcoinStartup Raises $35 Million in 30 Seconds With Crypto-Currency OfferingBitcoinBitcoin Fans Say Cryptocurrency Tokens Are the Future of Tech FundingBitcoinWhy Bitcoin Just Dropped 30%In other words, the computers executing the stop loss orders began to sell at all costs and, so long as there was someone on the other side to match the order, the trade went through—even if the price was totally irrational, and driven only by an algorithmic frenzy.Get Data Sheet, Fortune’s technology newsletterThis is hardly the first time such a thing has happened, of course.bitcoin dead in singapore

/DOGTnCnX2Q- Alex Melen (@amelen) June 22, 2017This is terrible news for those who sold Ethereum while the price was falling through the floor.It would be like seeing a computer sell of your Apple shares for $1 and not being able to do anything about it.Meanwhile, those who had put out "buy" orders to buy Ethereum if the price fell super-low would have made a killing.Some seasoned traders on discussion forums like Hacker News basically shrugged at the news, and said such events are not uncommon in foreign exchange trading, and that those who placed the stop-loss orders should have known better.bitcoin vietnam lua daoOthers noted this just how markets work, and praised GDAX for how they handled it:A trade is a trade...bitcoin ny teknikLarge sell fills the bids, triggers the S/L orders and then some!All is in 'order' folks.https://t.co/4iYfV7JV5D- Nigel Quantick (@nigelquantick) June 22, 2017So some1 placed a massive sell.cheapest bitcoin vps

As of Thursday morning, the price of one unit of Ethereum was $330, according to CoinDesk.go-ethereum: /ethereum/go-ethereum/ Index | Examples | Files /ethereum/go-ethereum/rlp" Package rlp implements the RLP serialization format.The purpose of RLP (Recursive Linear Prefix) is to encode arbitrarily nested arrays of binary data, and RLP is the main encoding method used to serialize objects in Ethereum.The only purpose of RLP is to encode structure; encoding specific atomic data types (eg.strings, ints, floats) is left up to higher-order protocols; in Ethereum integers must be represented in big endian binary form with no leading zeroes (thus making the integer value zero equivalent to the empty byte array).RLP values are distinguished by a type tag.The type tag precedes the value in the input stream and defines the size and kind of the bytes that follow.decode.go doc.go encode.go raw.go typecache.go ❖var ( = errors.New("rlp: end of list") = errors.New("rlp: expected String or Byte") = errors.New("rlp: expected List") = errors.New("rlp: non-canonical integer format") = errors.New("rlp: non-canonical size information") = errors.New("rlp: element is larger than containing list") = errors.New("rlp: value size exceeds available input length") = errors.New("rlp: input contains more than one value") )❖var ( = []byte{0x80} = []byte{0xC0} ) ❖func CountValues(b []byte) (int, error) CountValues counts the number of encoded values in b.

❖func Decode(r io.Reader, val interface{}) error Decode parses RLP-encoded data from r and stores the result in the value pointed to by val.Val must be a non-nil pointer.If r does not implement ByteReader, Decode will do its own buffering.Decode uses the following type-dependent decoding rules: If the type implements the Decoder interface, decode calls DecodeRLP.To decode into a pointer, Decode will decode into the value pointed to.If the pointer is nil, a new value of the pointer's element type is allocated.If the pointer is non-nil, the existing value will be reused.To decode into a struct, Decode expects the input to be an RLP list.The decoded elements of the list are assigned to each public field in the order given by the struct's definition.The input list must contain an element for each decoded field.Decode returns an error if there are too few or too many elements.The decoding of struct fields honours certain struct tags, "tail", "nil" and "-".

The "-" tag ignores fields.For an explanation of "tail", see the example.The "nil" tag applies to pointer-typed fields and changes the decoding rules for the field such that input values of size zero decode as a nil pointer.This tag can be useful when decoding recursive types.To decode into a slice, the input must be a list and the resulting slice will contain the input elements in order.For byte slices, the input must be an RLP string.Array types decode similarly, with the additional restriction that the number of input elements (or bytes) must match the array's length.To decode into a Go string, the input must be an RLP string.The input bytes are taken as-is and will not necessarily be valid UTF-8.To decode into an unsigned integer type, the input must also be an RLP string.The bytes are interpreted as a big endian representation of the integer.If the RLP string is larger than the bit size of the type, Decode will return an error.Decode also supports *big.Int.

There is no size limit for big integers.To decode into an interface value, Decode stores one of these in the value: Non-empty interface types are not supported, nor are booleans, signed integers, floating point numbers, maps, channels and functions.Note that Decode does not set an input limit for all readers and may be vulnerable to panics cause by huge value sizes.If you need an input limit, use Example Code: Output: Example (StructTagNil) Code: Output: Example (StructTagTail) Code: ❖func DecodeBytes(b []byte, val interface{}) error DecodeBytes parses RLP data from b into val.Please see the documentation of Decode for the decoding rules.The input must contain exactly one value and no trailing data.❖func Encode(w io.Writer, val interface{}) error Encode writes the RLP encoding of val to w. Note that Encode may perform many small writes in some cases.Consider making w buffered.Encode uses the following type-dependent encoding rules: If the type implements the Encoder interface, Encode calls EncodeRLP.

This is true even for nil pointers, please see the documentation for Encoder.To encode a pointer, the value being pointed to is encoded.For nil pointers, Encode will encode the zero value of the type.A nil pointer to a struct type always encodes as an empty RLP list.A nil pointer to an array encodes as an empty list (or empty string if the array has element type byte).Struct values are encoded as an RLP list of all their encoded public fields.Recursive struct types are supported.To encode slices and arrays, the elements are encoded as an RLP list of the value's elements.Note that arrays and slices with element type uint8 or byte are always encoded as an RLP string.A Go string is encoded as an RLP string.An unsigned integer value is encoded as an RLP string.Zero always encodes as an empty RLP string.Encode also supports *big.Int.An interface value encodes as the value contained in the interface.Boolean values are not supported, nor are signed integers, floating point numbers, maps, channels and functions.

❖func EncodeToBytes(val interface{}) ([]byte, error) EncodeBytes returns the RLP encoding of val.Please see the documentation of Encode for the encoding rules.❖func EncodeToReader(val interface{}) (size int, r io.Reader, err error) EncodeReader returns a reader from which the RLP encoding of val can be read.The returned size is the total size of the encoded data.ListSize returns the encoded size of an RLP list with the given content size.❖func SplitList(b []byte) (content, rest []byte, err error) SplitList splits b into the content of a list and any remaining bytes after the list.❖func SplitString(b []byte) (content, rest []byte, err error) SplitString splits b into the content of an RLP string and any remaining bytes after the string.❖type ByteReader interface { io.Reader io.ByteReader } ByteReader must be implemented by any input reader for a Stream.It is implemented by e.g.❖type Decoder interface { (*Stream) error } Decoder is implemented by types that require custom RLP decoding rules or need to decode into private fields.

The DecodeRLP method should read one value from the given Stream.It is not forbidden to read less or more, but it might be confusing.❖type Encoder interface { (io.Writer) error } Encoder is implemented by types that require custom encoding rules or want to encode private fields.Example Code: Kind represents the kind of value contained in an RLP stream.❖const ( Kind = iota ) ❖func Split(b []byte) (k Kind, content, rest []byte, err error) Split returns the content of first RLP value and any bytes after the value as subslices of b.❖func (k Kind) String() string RawValue represents an encoded RLP value and can be used to delay RLP decoding or to precompute an encoding.Note that the decoder does not verify whether the content of RawValues is valid RLP.Stream can be used for piecemeal decoding of an input stream.This is useful if the input is very large or if the decoding rules for a type depend on the input structure.

Stream does not keep an internal buffer.After decoding a value, the input reader will be positioned just before the type information for the next value.When decoding a list and the input position reaches the declared length of the list, all operations will return error EOL.The end of the list must be acknowledged using ListEnd to continue reading the enclosing list.Stream is not safe for concurrent use.Example Code: Output: ❖func NewListStream(r io.Reader, len uint64) *Stream NewListStream creates a new stream that pretends to be positioned at an encoded list of the given length.❖func NewStream(r io.Reader, inputLimit uint64) *Stream NewStream creates a new decoding stream reading from r. If r implements the ByteReader interface, Stream will not introduce any buffering.For non-toplevel values, Stream returns ErrElemTooLarge for values that do not fit into the enclosing list.Stream supports an optional input limit.If a limit is set, the size of any toplevel value will be checked against the remaining input length.

Stream operations that encounter a value exceeding the remaining input length will return ErrValueTooLarge.The limit can be set by passing a non-zero value for inputLimit.If r is a bytes.Reader or strings.Reader, the input limit is set to the length of r's underlying data unless an explicit limit is provided.❖func (s *Stream) Bool() (bool, error) Bool reads an RLP string of up to 1 byte and returns its contents as a boolean.If the input does not contain an RLP string, the returned error will be ErrExpectedString.❖func (s *Stream) Bytes() ([]byte, error) Bytes reads an RLP string and returns its contents as a byte slice.If the input does not contain an RLP string, the returned error will be ErrExpectedString.❖func (s *Stream) Decode(val interface{}) error Decode decodes a value and stores the result in the value pointed to by val.Please see the documentation for the Decode function to learn about the decoding rules.❖func (s *Stream) Kind() (kind Kind, size uint64, err error) Kind returns the kind and size of the next value in the input stream.

The returned size is the number of bytes that make up the value.For kind == Byte, the size is zero because the value is contained in the type tag.The first call to Kind will read size information from the input reader and leave it positioned at the start of the actual bytes of the value.Subsequent calls to Kind (until the value is decoded) will not advance the input reader and return cached information.❖func (s *Stream) List() (size uint64, err error) List starts decoding an RLP list.If the input does not contain a list, the returned error will be ErrExpectedList.When the list's end has been reached, any Stream operation will return EOL.❖func (s *Stream) ListEnd() error ListEnd returns to the enclosing list.The input reader must be positioned at the end of a list.❖func (s *Stream) Raw() ([]byte, error) Raw reads a raw encoded value including RLP type information.❖func (s *Stream) Reset(r io.Reader, inputLimit uint64) Reset discards any information about the current decoding context and starts reading from r. This method is meant to facilitate reuse of a preallocated Stream across many decoding operations.
