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. 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. They allow the sender to fund an arbitrary transaction, no matter how complicated, using a byte hash" 1. Pay-to-Pubkey-hash addresses are similarly a byte hash of the public key. Pay-to-script-hash provides a means for complicated transactions, unlike the Pay-to-pubkey-hash, which has a specific definition for scriptPubKey, and scriptSig.

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.

Generations have a single input, and this input has a " coinbase " parameter instead of a scriptSig. It is a unique type of bitcoin transaction that can be created by a miner.

The miners use it to collect the block reward for their work and any other transaction fees collected by the miner are also sent in this transaction.

Each transaction executed on the bitcoin network are combined together to form a block. When a block is formed, immediately, it will be added in the blockchain. Now, these blocks are immutable and tamper-proof for all transactions that are made on the bitcoin network. Each block must contain one or more transactions, and the first transaction in the block is called the coinbase transaction.

The miners are always responsible for creating a block. When a block is successfully created, he will be rewarded from bitcoin for their work. The bitcoin block reward is always dependent on the number of blocks from the genesis block and the number of fees included in the transactions of the block.

The total amount of rewards that a miner will collect is the sum of the block reward and the transaction fees taken from all the transactions that have been included in the block. Miners often use the scriptSig for strings of text. This is a safeguard to prevent outputs that originate from the coinbase transaction from becoming unspendable in the event the mined block moves out of the active chain due to a fork.

I'll let you know about cool website updates , or if something seriously interesting happens in bitcoin. Don't worry, it doesn't happen very often. Usage When a miner creates a candidate block , the very first space for a transaction is reserved for the coinbase transaction. Every block must have a coinbase transaction.
