For example, imagine Mark previously received 0. Now, in order to send 1 BTC to Jessica, there might be two inputs: one input of 0. In this case, the amount Mark wants to send is 1 BTC. There are two outputs. The second is 0. This second output is calculated as the total of the inputs [0. 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! Broadcasting and confirmations 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.
