How does Bitcoin work? Have you ever wondered how Bitcoin works while thinking about ‘digital gold’? Have you ever wondered how to pay someone in Bitcoin? Or how to even conduct a Bitcoin transaction? Here, we explain how a Bitcoin (BTC) transaction unfolds and the nuts and bolts behind it.
Why should investors understand Bitcoin?
Asher Tan, CEO of CoinJar, says normal currencies, like the Great British Pound, are controlled by the government and banks. “But Bitcoin operates on a network that is decentralised. This means no single entity has the power to manipulate it, making it resistant to censorship and inflation. It’s the people’s money.”
Tan says, “You can send and receive it instantly across the globe, without the need for intermediaries. It’s a true global currency.”
Tan says that Bitcoin’s underlying technology, blockchain, is sparking innovation across various industries. “From supply chain management to voting systems, blockchain has the potential to change the way we do life.”
Overview of Bitcoin transactions
Bitcoin is like a type of digital cash. Instead of physical coins or bills, you have digital “coins” stored in a digital wallet.
When you want to send Bitcoin to someone, it’s like handing them some of your digital coins. However, instead of a physical exchange, this transaction happens on the Bitcoin blockchain.
Think of the blockchain as a giant digital ledger that records every Bitcoin transaction ever made. It’s like a huge book where everyone can see all the transactions, but no one can change or erase them.
There are no banks or middlemen involved. Instead, a network of computers all around the world work together to verify and record your transaction. These computers are like accountants, making sure everything is correct.
How do Bitcoins work? Role of mining
So how are Bitcoin transactions verified? The process they use to verify transactions is called “mining.”
Miners get Bitcoin as a reward for solving complex problems and adding new transactions to the blockchain. This is how new “blocks” are added to the ledger.
Components of a Bitcoin Transaction
A Bitcoin transaction is like a digital money transfer. Here are the main parts:
Inputs
Think of these as the source of your Bitcoin. They’re like pulling money out of your digital wallet to spend.
Outputs
This is where your Bitcoin is going. It’s like writing down the address of the person (or place) you’re sending money to, and how much they’ll receive.
Transaction ID (TXID)
This is like a unique receipt number for your transaction. It’s used to track and verify it on the blockchain (the public record of all Bitcoin transactions).
Signatures
These are digital signatures that prove you own the Bitcoin you’re spending and give permission for the transaction to happen.
Transaction Fee
This is the amount of Bitcoin paid to the miners who confirm and record your transaction on the blockchain. It’s like a tip to incentivise them and also helps prevent spam on the network.
Transaction process: How do you send Bitcoins?
Here is how the transaction process happens, in the order it takes place.
Transaction initiation: A user creates a transaction using a Bitcoin wallet, specifying the recipient’s address and the amount to send.
Transaction broadcasting: The transaction is broadcast to the Bitcoin network.
Transaction verification: Bitcoin miners verify the transaction’s validity by checking signatures, ensuring sufficient funds in the inputs, and confirming that the inputs haven’t been spent already.
Transaction inclusion in a block: Validated transactions are bundled together into blocks by miners.
Block addition to the blockchain: Miners compete to solve a complex mathematical puzzle. The first miner to solve it adds their block to the blockchain.
Transaction confirmation: As subsequent blocks are added to the blockchain, the transaction gains more confirmations and becomes increasingly protected.
Transaction fees
Transaction fees are a crucial element of the Bitcoin network. They serve several purposes.
Incentivising miners
Miners receive transaction fees as a reward for their work in verifying and recording transactions.
Prioritising transactions
An increase in the price of fees can incentivise miners to prioritise a transaction, leading to more timely confirmations.
Network Protection
Fees help deter spam attacks and ensure the network’s overall protection. The amount of a transaction fee can vary depending on factors like transaction size, network congestion, and the sender’s desired confirmation time.
Common questions and issues
Transactions might not always go as planned.
Transaction delays
If there is heavy network activity, transactions may take longer than expected to confirm.
Unconfirmed transactions
Transactions with competitive fees or where the fees have decreased, might remain unconfirmed for extended periods.
Double-spending
Double-spending can happen if someone tries to send the same Bitcoin to two different recipients at the same time. However, the Bitcoin network is designed to prevent this by confirming and verifying all transactions before they are finalised. Only one of the transactions will be considered valid, and the other will be rejected.
Protection measures
Bitcoin transactions are generally considered protected due to the cryptographic techniques used and the decentralised nature of the network. However, it’s important to take precautions.
Always verify the recipient’s Bitcoin address before sending a transaction. Make double sure that it is correct. This will avoid sending Bitcoin to the wrong address.
Opt for well-established and protected wallets. Hardware wallets, which store your Bitcoin offline, offer the highest level of protection. Software wallets with strong protection features are also viable options.
Activate 2FA whenever possible. This adds an extra layer of protection, requiring a code from your phone or another device in addition to your password to access your Bitcoin wallet.
Be wary of scam emails, messages, or websites that ask for your private keys or login credentials. Legitimate services will never request this information.
Bitcoin: How it works
Satoshi Nakamoto, the pseudonymous creator of Bitcoin, introduced a revolutionary concept: a peer-to-peer digital currency that operates independently of any government or financial institution. Unlike traditional fiat currencies like the Great British Pound, Bitcoin has a finite supply of 21 million coins, making it resistant to inflation.
Transactions in Bitcoin are facilitated through a decentralised public ledger known as the blockchain. When you buy or sell Bitcoin, your transaction is broadcast to the network of miners who verify and record it on the blockchain.
This process promises transparency and protection, as each transaction is publicly viewable and difficult to alter.
You can invest in Bitcoin through cryptocurrency exchanges or by accepting it as payment for goods and services. While not many retailers accept Bitcoin outright, there are now crypto credit cards, like those offered by Mastercard and Visa, which are accepted everywhere normal credit cards are accepted. The bitcoin price uk has seen significant fluctuations, influenced by market trends and regulatory changes.Understanding how Bitcoin transactions work is essential for anyone venturing into the world of cryptocurrencies.
Conclusion: Understanding how Bitcoin works
Bitcoin, with its groundbreaking technology and potential for economic disruption, is far more than just a digital currency. Understanding its inner workings, from the blockchain’s decentralised ledger to the cryptographic principles ensuring protection, is crucial for anyone interested in the future of finance.
As Bitcoin continues to evolve and influence global markets, those who grasp its fundamentals will be best positioned to navigate the opportunities and challenges that lie ahead. Taking the time to learn about Bitcoin is an investment in understanding the technology that’s shaping our financial landscape.

UK residents are required (in accordance with local legislation) to complete an appropriateness assessment to show they understand the risks associated with what crypto/investment they are about to buy and enabling CoinJar to categorize them as an investor. New customers are also required under local regulations to wait 24-hours as a “cooling off” period (from account creation), before their account is active (i.e. to deposit, trade, withdraw etc.).
Cryptocurrency is currently not regulated in the UK. It’s vital to understand that once your money is in the crypto ecosystem, there are no rules to protect it, unlike with regular investments. You should not expect to be protected if something goes wrong. So, if you make any crypto-related investments, you’re unlikely to have recourse to the Financial Services Compensation Scheme (FSCS) or the Financial Ombudsman Service (FOS) if something goes wrong.
Remember:
Don’t invest unless you’re prepared to lose all the money you invest. This is a high‑risk investment and you should not expect to be protected if something goes wrong. Take 2 mins to learn more.
