Jump to: , Byte-map of Transaction with each type of TxIn and TxOut A transaction is a transfer of Bitcoin value that is broadcast to the network and collected into blocks.A transaction typically references previous transaction outputs as new transaction inputs and dedicates all input Bitcoin values to new outputs.Transactions are not encrypted, so it is possible to browse and view every transaction ever collected into a block.Standard transaction outputs nominate addresses, and the redemption of any future inputs requires a relevant signature.All transactions are visible in the block chain, and can be viewed with a hex editor.A block chain browser is a site where every transaction included within the block chain can be viewed in human-readable terms.This is useful for seeing the technical details of transactions in action and for verifying payments.Contents 1 2 3 4 5 6 The input in this transaction imports 50 BTC from output #0 in transaction f5d8... Then the output sends 50 BTC to a Bitcoin address (expressed here in hexadecimal 4043... instead of the normal base58).

When the recipient wants to spend this money, he will reference output #0 of this transaction in an input of his own transaction.An input is a reference to an output from a previous transaction.Multiple inputs are often listed in a transaction.All of the new transaction's input values (that is, the total coin value of the previous outputs referenced by the new transaction's inputs) are added up, and the total (less any transaction fee) is completely used by the outputs of the new transaction.litecoin bank transferPrevious tx is a hash of a previous transaction.ethereum chart graphIndex is the specific output in the referenced transaction.bitcoin average cadScriptSig is the first half of a script (discussed in more detail later).bitcoin aml risks

The script contains two components, a signature and a public key.The public key must match the hash given in the script of the redeemed output.The public key is used to verify the redeemers signature, which is the second component.More precisely, the second component is an ECDSA signature over a hash of a simplified version of the transaction.bitcoin kurs schweizIt, combined with the public key, proves the transaction was created by the real owner of the address in question.set up offline bitcoin walletVarious flags define how the transaction is simplified and can be used to create different types of payment.uk bitcoin hmrcAn output contains instructions for sending bitcoins.1 gh bitcoin mining

Value is the number of Satoshi (1 BTC = 100,000,000 Satoshi) that this output will be worth when claimed.ScriptPubKey is the second half of a script (discussed later).There can be more than one output, and they share the combined value of the inputs.Because each output from one transaction can only ever be referenced once by an input of a subsequent transaction, the entire combined input value needs to be sent in an output if you don't want to lose it.bitcoin kurs 500If the input is worth 50 BTC but you only want to send 25 BTC, Bitcoin will create two outputs worth 25 BTC: one to the destination, and one back to you (known as "change", though you send it to yourself).bitcoin mining shaAny input bitcoins not redeemed in an output is considered a transaction fee; whoever generates the block will get it.gia tien bitcoin

A sends 100 BTC to C and C generates 50 BTC.C sends 101 BTC to D, and he needs to send himself some change.D sends the 101 BTC to someone else, but they haven't redeemed it yet.Only D's output and C's change are capable of being spent in the current state.To verify that inputs are authorized to collect the values of referenced outputs, Bitcoin uses a custom Forth-like scripting system.asic bitcoin miners for saleThe input's scriptSig and the referenced output's scriptPubKey are evaluated (in that order), with scriptPubKey using the values left on the stack by scriptSig.bitcoin wert 2015The input is authorized if scriptPubKey returns true.bitcoin voucher code freeThrough the scripting system, the sender can create very complex conditions that people have to meet in order to claim the output's value.bitcoin kurs euro chart

For example, it's possible to create an output that can be claimed by anyone without any authorization.It's also possible to require that an input be signed by ten different keys, or be redeemable with a password instead of a key.Bitcoin currently creates two different scriptSig/scriptPubKey pairs.These are described below.asic bitcoin miner saleIt is possible to design more complex types of transactions, and link them together into cryptographically enforced agreements.main cày bitcoinThese are known as Contracts.linux bitcoin poolA Bitcoin address is only a hash, so the sender can't provide a full public key in scriptPubKey.bitcoin loans no verificationWhen redeeming coins that have been sent to a Bitcoin address, the recipient provides both the signature and the public key.sklep za bitcoin

The script verifies that the provided public key does hash to the hash in scriptPubKey, and then it also checks the signature against the public key.P2SH addresses were created with the motivation of moving "the responsibility for supplying the conditions to redeem a transaction from the sender of the funds to the redeemer.ethereum pool sourceThey allow the sender to fund an arbitrary transaction, no matter how complicated, using a 20-byte hash"1.bitcoin botnet proxyPay-to-Pubkey-hash addresses are similarly a 20-byte hash of the public key.bitcoin to litecoin calculatorPay-to-script-hash provides a means for complicated transactions, unlike the Pay-to-pubkey-hash, which has a specific definition for scriptPubKey, and scriptSig.bitcoin script escrow

The specification places no limitations on the script, and hence absolutely any contract can be funded using these addresses.The scriptPubKey in the funding transaction is script which ensures that the script supplied in the redeeming transaction hashes to the script used to create the address.In the scriptSig above, 'signatures' refers to any script which is sufficient to satisfy the following serialized script.bitcoin nyse symbolGenerations have a single input, and this input has a "coinbase" parameter instead of a scriptSig.bitcoin rx 480The data in "coinbase" can be anything; it isn't used.bitcoin crowdsaleBitcoin puts the current compact-format target and the arbitrary-precision "extraNonce" number there, which increments every time the Nonce field in the block header overflows.bitcoin paling banyak

Outputs can be anything, but Bitcoin creates one exactly like an IP address transaction.The extranonce contributes to enlarge the domain for the proof of work function.Miners can easily modify nonce (4byte), timestamp and extranonce (2 to 100bytes).The input sufficiently describes where and how to get the bitcoin amout to be redeemed.bitcoin sklepIf it is the (only) input of the first transaction of a block, it is called the generation transaction input and its content completely ignored.litecoin jpy(Historically the Previous Transaction hash is 0 and the Previous Txout-index is -1.)litecoin increase 2017The output sets the conditions to release this bitcoin amount later.litecoin more secure than bitcoin
