An "unconfirmed" transaction is one which is recent enough to not be considered a canonical part of the block chain. Once enough blocks have been added to the block chain after the one in which your transaction is recorded it will be considered confirmed. The .

Active Oldest Votes. Unconfirmed transactions are perfectly valid and can be spent, though wallets try to avoid it. Immature coins are generations which do not have confirmations yes, and these are effectively invalid worthless before they are. Pieter Yes sorry absolutely right.

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. The input in this transaction imports 50 BTC from output 0 in transaction f5d Then the output sends 50 BTC to a Bitcoin address expressed here in hexadecimal 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. Previous tx is a hash of a previous transaction. Index is the specific output in the referenced transaction.

ScriptSig is the first half of a script discussed in more detail later. 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.

It, combined with the public key, proves the transaction was created by the real owner of the bitcoins in question. Various flags define how the transaction is simplified and can be used to create different types of payment. An output contains instructions for sending bitcoins. 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. If 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. Any input bitcoins not redeemed in an output is considered a transaction fee ; whoever generates the block can claim it by inserting it into the coinbase transaction of that block.

To verify that inputs are authorized to collect the values of referenced outputs, Bitcoin uses a custom Forth-like scripting system. The 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. The input is authorized if scriptPubKey returns true. Through the scripting system, the sender can create very complex conditions that people have to meet in order to claim the output's value.

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. It is possible to design more complex types of transactions, and link them together into cryptographically enforced agreements. These are known as Contracts. A Bitcoin address is only a hash, so the sender can't provide a full public key in scriptPubKey.

When redeeming coins that have been sent to a Bitcoin address, the recipient provides both the signature and the public key.
