Normally there will be either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and at most two outputs: one for the payment, and one returning the change, if any, back to the sender. Let's break down that section of the Bitcoin white paper by looking at a sample transaction in practice:.

Mark wants to send 1 BTC to Jessica. To do this, he uses his private key to 'sign' a message with the transaction-specific details. This message, which must be broadcast to the network, will contain the following:. This might seem confusing, but it's done this way to improve efficiency - and the good news is that knowing the behind-the-scenes details of Bitcoin transactions is not required to send or receive bitcoin.

Your Bitcoin Wallet takes care of that! In the above example, Mark via his wallet software will broadcast his proposed transaction to the Bitcoin network. A special group of participants in the network known as 'miners' verify that Mark's keys are able to access the inputs i.

Miners also gather together a list of other transactions that were broadcast to the network around the same time as Mark's and form them into a block. Any miner who has completed the ' Proof of Work ' is permitted to propose a new block that will be added or 'attached' to the chain and by referencing the last block. That new block is then broadcast to the network. If other network participants nodes agree it's a valid block ie.

Eventually, another miner will build on top of it by referencing it as the previous block when proposing the next block. Any transactions that were in the previous block will now have been 'confirmed' by the next miner. As blocks are added to the chain, the number of confirmations of Mark's transaction increases.

Each block can only contain a certain number of transactions, and that number is determined largely by the space available in each block, or the 'block size,' which is 1MB. The limited space gives rise to the fee market, where miners, who collect fees, choose to include in the next block only those transactions which have included a high enough fee.

Thus higher fees act as incentive for miners to prioritize your transactions. Note that the block size is an arbitrary limit, but the Bitcoin community has chosen to keep the block size as small as possible in order to make it easier for people to operate Bitcoin nodes.

Bitcoin Cash , which is a fork of Bitcoin, has a larger block size and therefore requires much lower fees for transactions. Read more: Understand how the Bitcoin network decides on critical issues like the block size. The reason for the big variation is that Bitcoin fees depend on both supply and demand ie. Size is affected primarily by inputs, so if your transaction has many inputs, it will take up more block space, and demand a higher fee.

For example, if you want to send 10 BTC, there's a good chance your transaction will require more inputs than if you want to send 1 BTC. Many wallets, including the Bitcoin. This helps you to avoid overpaying. For example, if you're not in a rush, you can set the fee the lower such that it will be picked up by a miner when the network is less congested. You can also ensure your transactions are processed immediately by increasing your fee.

The input and outputs have values. The transaction is less than the block size of 1 MB. The values must be more than 0 and less than 21 million. None of the inputs have a hash that is equal to 0. The locktime is less than the maximum allowed number. The transaction size is greater than or equal to bytes. The number of signatures is less than the signatute limit. The unlocking script can only push numbers onto the stack.

The locking script must match isstandard format. A matching transaction must exist. If a transaction is missing move the transaction to the orphan transaction pool. If the transaction is a coinbase transaction then it must have a maturity of confirmations. For each input the output must exist and not have been spent. Check that each input value is in the required range. Reject if the input value is less than the output value.
