How does bitcoin work?
You probably have had about bitcoin and are wondering how does bitcoin work? or maybe you don’t even know what is bitcoin you can read this article: What is bitcoin & crypto currency
In addition to being the first cryptocurrency, Bitcoin (BTC) is also the most well-known of the more than 19,000 cryptocurrencies that are currently in use. Every new dramatic high and sickening low is eagerly covered by the financial media, making Bitcoin an inevitable part of the landscape.
Even though the extreme volatility makes for exciting news, it hardly makes Bitcoin the greatest option for those who are new to investing or seeking a reliable store of value. It can be challenging to comprehend all the details; let’s look more closely at the question how does Bitcoin work .
A blockchain is a distributed digital ledger that serves as the foundation of bitcoin. As its name suggests, a blockchain is a network of interconnected data made up of units called blocks that each contain details about a single transaction, such as the date and time, the total amount, the buyer and seller, and a special identification number for each trade. A digital chain of blocks is created by connecting entries chronologically.
According to Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs, “Once a block is added to the blockchain, it becomes accessible to anybody who desires to access it, acting as a public database of cryptocurrency transactions.”
Blockchain is decentralized, thus no single entity has power over it. According to Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax, “It’s like a Google Doc that anyone can collaborate on.” Everyone with a link can add to it, but no one owns it. Additionally, your copy is updated when it is changed by other users.
Although it may seem dangerous that anyone might alter the blockchain, this is exactly what makes Bitcoin reliable and safe. A majority of Bitcoin holders must confirm a transaction block before it can be added to the blockchain. Additionally, the unique codes used to identify users’ wallets and transactions must follow the correct encryption pattern.
These codes are lengthy, random numbers, which makes it very challenging to manufacture them falsely. The likelihood that anyone might make fraudulent Bitcoin transactions is significantly decreased by the quantity of statistical unpredictability in the blockchain verification codes, which are required for every transaction.
The Technology Behind Bitcoin
Bitcoin transactions seem quick and simple on the surface, and they really are. The huge ledger known as the blockchain, however, is what powers the technology that keeps the Bitcoin network functioning flawlessly in the background.
Because it holds a record of every bitcoin transaction that has ever occurred since the currency was originally introduced in 2009, it is enormous.
The blockchain’s size will increase as more time goes by and more transactions take place. This is how the blockchain works:

When you send a payment, your wallet or app sends a request to the Bitcoin network, which is comprised of computers known as nodes. These nodes then use well-known algorithms to validate your transaction.
Once your transaction has been verified and confirmed, it is combined with other transactions to form a new data block for the blockchain.
This new block is then added to the blockchain’s end. When this occurs, the transaction is complete and permanent.
From start to finish, this process takes about 10-45 minutes (which is why Bitcoin transactions do not happen instantly). No one can undo or delete a transaction once it has been completed.
The person to whom you sent the bitcoin payment (the receiver) will now see it in his wallet.
So, if there is no central body governing the network, who verifies and confirms transactions?
The miners are the answer. Miners are the literal lifeblood of the bitcoin network. Some have even compared miners to hamsters in a wheel who keep the Bitcoin network running! This is true.
Miners contribute so much to Bitcoin’s success that they truly deserve to be rewarded in precious bitcoins. There would be no new blocks added to the blockchain if they did not exist.
No transactions are ever completed if nothing is added to the blockchain.
This means that no bitcoin payments are sent or received on the network. There will be no new bitcoins created.
Miners are compensated in bitcoins for their efforts because they are essential to the Bitcoin network (it would not make any sense to reward them in traditional paper currency). They are almost like network employees.
Because there are only 21 million bitcoins, the number of bitcoins that miners are paid with will continue to dwindle until all bitcoins are depleted by around 2140.
Now that you understand what Bitcoin and cryptocurrency are all about, let’s move on to the next guide, where you’ll learn how bitcoin’s value is determined.
