Danny Bradbury wrote about bitcoin and other cryptocurrencies for The Balance. He has won awards for his investigative reporting on cybercrime. Bitcoin transactions are more complex than you might think. You rarely simply send an amount of bitcoin in one go. Instead, your bitcoin wallet and the bitcoin network have to go through a set of steps to ensure that the right amount of electronic money gets to the recipient.

The bitcoins that you send to someone were sent to you from someone else. When they sent them to you, the address that they sent from was registered on the bitcoin blockchain as the transaction input, and your address — the address they sent it to — was registered on the bitcoin network as the transaction output.

That transaction will then be registered on the bitcoin network with your bitcoin address as the transaction input. Using this system, people can trace bitcoin transactions all the way through to when the bitcoin was first created, understanding who sent it to whom, at any point in time.

This creates a completely transparent system in which all transactions can be checked at any time. So, if Alice has a bitcoin address with one bitcoin in it, and she only wants to send Bob half a bitcoin, then she would have to send Bob that entire bitcoin. The bitcoin network would then automatically create 0. That third address will also be a transaction output, meaning that the address will have multiple transaction outputs.

Over time, this means that bitcoin wallets end up with lots of addresses containing varying amounts of bitcoin and change from bitcoin transactions. When you send bitcoins to someone, your wallet will try its best to piece together the necessary funds using the addresses containing the different amounts.

That leads to transactions that can have several different inputs — different addresses with different amounts used to make up the funds. What if you want to send just a tiny amount of bitcoin? Luckily, you can slice bitcoins very thinly indeed. The smallest divisible part of a bitcoin is called a satoshi, and it amounts to just one hundred millionth of a bitcoin.

The smallest transaction value is satoshis, which is still pretty tiny. This is something to consider, especially when sending tiny fractions of a bitcoin. Bitcoin Basics. The transaction input is the bitcoin address from which the money was sent.

The transaction output is the bitcoin address to which the money was sent. If the bitcoin is in your wallet, that will be the bitcoin address under your control.

The amount is the amount of bitcoin that was sent. Continue Reading.
