Bitcoin and the Bitcoin Transaction Chain: What You Need to Know

What is the definition of a Bitcoin transaction? It is necessary to go over Bitcoin's core functioning principles in order to grasp its significance and appreciate its valuable features. As a result, we'll go over Bitcoin's characteristics and functions in order to understand how it works and why it's different from other currencies in terms of security. You'll also learn how to process Bitcoin payments, including how to validate, confirm, and check them.

In 2009, Bitcoin was introduced as an alternative currency to address problems with financial transactions:

  • being unable to manage your own finances

  • coping with non-atomic transfers (transactions that aren't executed immediately even after they've been submitted)

  • coping with the freezing of funds

Due to the participation of middlemen and centralised administration in the traditional finance business, users began to face the aforementioned concerns more frequently. Many people become victims of fraud as a result of their inability to regulate their finances. People have accused banks of misusing cash, having affairs, and charging exorbitant fees. As a result, Satoshi Nakamoto, the creator of Bitcoin, suggested a new solution: the Bitcoin digital money. Its goal was to remove deceptive financial schemes, increase transparency for customers, and reduce interest fees through decentralisation.

Bitcoin is a decentralised currency rather than a centralised payment system. This is its most distinguishing feature, as it is a self-contained, decentralised digital currency. Users may regain complete control over their funds and avoid issues like fund freezing and unfair laws. Bitcoin is often referred to as "digital gold" because to similarities in the following characteristics:

  • supply is limited

  • mining is a must

  • independence

  • counterfeiting is no longer a problem

With Bitcoin, you may send money to anybody, anywhere, and for any reason. Furthermore, blockchain implementation ensures a higher level of security. Despite the fact that transactions are transparent and easy to follow, it is impossible to determine who submitted them because all usernames are encrypted. This contributes to the anonymity feature in a positive way.

Bitcoin Price

Bitcoin's popularity has surged as a result of rising demand. Its worth is determined by interest and supply. As a result, the greater the number of Bitcoin users, the higher the currency's value. Bitcoin's initial price was only a few cents, which is a fascinating fact!

The price of bitcoin has fluctuated between $6,000 and $7,300 in the last two months:

Taking past price changes into account, Bitcoin has had its ups and downs, reaching a high of $19,000 in 2017 and then falling by 69 percent in 2018.

Though Bitcoin's price isn't as high as it once was, we should note that the currency is getting less volatile. In the bitcoin market, lower volatility is a big benefit because it ensures reliability and safety. The Bitcoin market, according to Chainalysis analysis, is maturing rather than disappearing. The currency stability from August to October reflects this. In comparison to Ripple and Ether, Bitcoin was less volatile while staying within the same price range.

The graph below depicts variations in cryptocurrency prices from August to October 2018:

Bitcoin has become one of the most popular cryptocurrencies in the modern market, thanks to features such as multi-purpose use, a simple registration process, and the option of anonymity.

Let's take a deeper look at the Bitcoin transaction process and discover how it actually works.

What Is the Process of a Bitcoin Transaction?

You must first purchase Bitcoin before sending it to a recipient. Please take a look at the following platforms for storing, buying, and exchanging bitcoins:

  • CoinPayments

  • Cryptopay

  • Changelly

There are a few alternative options for buying Bitcoin:

You don't have to go into the technical specifics to understand how transactions function if you're a new user. We'll go over the fundamental phrases to give you a complete view.

You can exchange your bitcoin address with others to process and receive payments as soon as you instal a digital wallet (learn more about the different types here).

The transaction procedure is fairly straightforward. It's the same as sending an email. The main distinction is that your Bitcoin address can only be used once.

Your digital wallet, in fact, does not contain the actual Bitcoin. It saves its address, all subsequent transaction records, and the balance as an output.

Bitcoin Transaction Chain: Balances

A Bitcoin transaction chain is a collection of transaction records and data held in a decentralised public ledger. A transaction's record is added to the main blockchain once it has been confirmed. This allows Bitcoin wallets to calculate a spendable balance and fresh transactions to pass the verification process. Furthermore, the actual owner can assess whether or not he or she has adequate finances to complete the deal. The record sequence and integrity are ensured using cryptography.

Public and Private Keys for Transactions

A transaction is a term used to describe the movement of funds from one wallet to another. The wallet stores the user's addresses and personal information. The address is a string of 34 letters and numbers known as the "public key." The public key may be viewed by anybody, but it has nothing to do with security because it is just a collection of symbols that does not contain any secret information.

A set of symbols and letters known as a "private key" is required to sign and send bitcoin transactions. With a mathematical proof, it ensures that the transaction comes directly from the owner. This information is made up of 64 symbols, and it is critical to keep it safe and off the internet so that no one can tamper with it. Despite the fact that private and public keys are related, there is no way to distinguish your private from your public key. The use of a signature is another approach to prevent cheating and tampering. To sign a transaction, you must first enter a private key into the Bitcoin programme, as well as transaction parameters such as transaction quantity and receiver. This information will be used by the programme to generate a digital signature, which you will then send to the main network for verification.

After transactions have been validated, they must go through the confirmation phase, often known as mining.

Mining is a method of verifying transactions.

What methods are used to confirm Bitcoin transactions? Within a decentralised, distributed consensus system, mining is the process of confirming transaction requests. Mining is required to:

  • within the ledger, implement the chronological order of transactions

  • allow different computers (nodes) to come to an agreement (agree on the system state)

  • maintain network neutrality and integrity

To go through the confirmation process, transactions must be included in a block that meets strict cryptographic standards and is verified by the network. To prevent data fraud or tampering with upcoming blocks, these constraints inhibit the change of earlier blocks. Furthermore, mining prevents the possibility of adding random blocks to the chain because each one must connect to the preceding one. As a result, no organisation or single person can control or replace the data housed by a block without first obtaining an agreement.

Various consensus algorithms are used in mining. They're all different in terms of price, how they got into the common state agreement, and how they use the blockchain platform. Let's look at the different sorts of consensus to better understand how mining works.

What does a Bitcoin transaction look like? First, consider the abbreviations used in the following example:

Now that we've covered the transaction process's basic working principle, let's have a look at its primary qualities and benefits.

Bitcoin's Assets

  • Irreversibility: Once a transaction has been confirmed, it cannot be reversed or returned by anyone. As a result, be sure you know where your money is going.

  • Anonymity: Transactions and accounts do not reveal the physical identities of the parties involved. You get payments from another encrypted address to your 34-character address. Even though the public ledger shows transaction flow, no one knows who transmitted what.

  • Speed and worldwide reach: Transactions can be sent very quickly, with confirmation arriving in a matter of minutes (approximately). Up to 6-7 transactions per second are possible on the Bitcoin Blockchain. With around 25 thousand transactions per second, Visa is a long way behind. This, on the other hand, is not dependent on your actual location, so you can process it from anywhere in the world, just like you can with Visa.

  • Security: The cryptography technology encrypts all of your funds. Only your private key and signature can be used to send them. Unless you haven't properly stored your private key, no one else will be able to do so.

  • Permissionless: There are no limitations or restrictions on where or how you send your own funds. It will not freeze, and no one will be able to take it away from you.

Let's take a look at some of the most often asked questions by users.

1. What Is the Best Way to Confirm a Bitcoin Transaction?

If you're wondering how to confirm a Bitcoin transaction, keep in mind that it must be approved by network nodes. A transfer must go through six stages in order to be completed.

Confirmation time is influenced by two factors:

  • transaction cost

  • network activity

The confirmation procedure is linked to the mining procedure we covered previously. The greater the number of outstanding transactions, the longer it takes for miners to process them so that they can be included in a block.

One block takes about 10 minutes to mine on average. Your transaction could take up to an hour to complete due to the six confirmation processes. The process can take several hours depending on the overall volume and network activity.

Furthermore, Bitcoin miners place a premium on transaction verifications with a greater fee.

2. How do I figure out how much I'll have to pay?

The size of each transaction varies. The cheapest charge is now computed as 60 Satoshis per byte. Let's imagine the size of your transaction is 300 bytes, and you need to multiply it by 60. You receive a charge of 18,000 Satoshis, which you must pay in order to confirm the transaction. You don't have to do anything to figure out the size of your transaction because any wallet will do it for you.

The following table shows how different wallets impose fees:

3. How Do I Check The Status Of My Bitcoin Transaction?

You may use a variety of websites to view Bitcoin transactions and learn more about blockchain activities. Some of the most well-known are:

It makes no difference where you check a bitcoin transaction. You can input your exact transaction details in the "search" area on any of the above-mentioned sites. In general, it's best to start with the digital address of the recipient - the person to whom you're sending money. If you've input everything correctly, you'll see a transaction list including the receiver's address. Frequently, the list looks to be excessively long. You can search for Bitcoin transactions by amount in this situation.

When looking up a Bitcoin transaction, you'll usually find the following transaction ID:

A green arrow indicates that the Bitcoin has been transferred or is in the process of being transferred to the receiving address. Those with a red arrow indicate that the Bitcoin has left the sender or is in the process of leaving.

4. What if the Transaction Isn't Confirmed?

Before entering a block, all pending transactions are normally kept in the mempool. Transactions can get stuck in the mempool for a long time, and the nodes that retain them can drop them out of the system. It will only be cancelled after that. There is also the option of rebroadcasting a transaction (an expired one). However, because you never know if a miner would include it, this can take even longer. In this scenario, the best course of action is to review the transaction again to check if there are any errors, incorrect addresses, or balance difficulties. You can also charge an additional fee to encourage it to be confirmed.


Bitcoin has risen to prominence as a leading cryptocurrency, and its use is spreading rapidly. Its appeal has also been aided by additional aspects such as enhanced stability and lower volatility. However, for some people, the procedure of using it may appear to be a little complicated. Though transactions are public and thus clear and observable, it is important to remember that Bitcoin's main advantages are security and anonymity, which are provided through encryption. We've defined the fundamental operating principles, as well as potential obstacles and remedies. Please contact Cryptoauxiliary if you have any questions. Our team is here to assist you!
