Bitcoin is a crypto asset that operates on a decentralized database called blockchain. Transactions on the Bitcoin network are recorded on a public ledger and verified by a network of nodes located throughout the world. This article will comprehensively discuss what Bitcoin is, how it works, history and its advantages. Let's take a look!
What is Bitcoin?
Bitcoin is a digital form of an asset. However, unlike the government-issued fiat currencies you're used to, there is no central bank controlling them.
In contrast, the financial system in Bitcoin is run by thousands of computers spread throughout the world. Anyone can participate in this ecosystem by downloading Bitcoin open source software.
Bitcoin is a digital asset that was announced in 2008 (and launched in 2009). It allows users to send and receive Bitcoins called bitcoins (with a lowercase b, or BTC).
What makes it especially attractive is its resistance to censorship, the impossibility of dual use of assets, and the ability to carry out transactions anytime and anywhere.

What Makes Bitcoin Unique?
The following are some of the main features that make Bitcoin unique:
1. Decentralization
Bitcoin operates on a decentralized public blockchain, meaning there is no central authority controlling it.
Instead, transactions are verified by a network of computers, known as nodes. Plus, anyone can join the network and help secure it.
2. Without permission
The permissionless nature of Bitcoin means anyone with an internet connection can participate in the Bitcoin network without authorization or permission from a central authority. Bitcoin allows users to send and receive payments with anyone on the network, regardless of location or identity.
This makes Bitcoin very popular in regions where access to traditional financial systems is limited or even non-existent.
3. Limited supply
Bitcoin has a limited supply of 21 million coins coded into the protocol. This means there will never be more than 21 million bitcoins in circulation, which helps prevent inflation.
4. Transparency
All bitcoin transactions are recorded in a public ledger that can be seen by all users. This means anyone can see the transactions that have occurred, including the number of bitcoins involved and the sender and recipient addresses.
In traditional financial systems, transactions are recorded by banks and other financial institutions, and this information is not available to the public. Instead, people rely on these institutions to keep accurate records.
5. Can be divided
Bitcoins can be divided into smaller units called satoshis, which are one hundred millionth of one bitcoin. This means that even if the price of bitcoin gets very high, people can still use it for very small amounts.
This makes bitcoin more accessible to people with limited financial resources and allows for more granular transactions.
How Does Bitcoin Work?
Pexel
When Alice makes a transaction with Bob, she doesn't send money as you might imagine. This is not like a digital asset transaction by handing him a 10 thousand rupiah note.
It's more like Alice wrote on a piece of paper (which everyone can see) that Alice gave 10 thousand rupiah to Bob. When Bob went to send the same funds to Carol, Carol could see that Bob had the 10 thousand rupiah by looking at the same paper.
The sheet is a database called a blockchain. All bitcoin network participants have the same copy stored on their devices. Participants connect with each other to synchronize new information.
To maintain the security and integrity of the blockchain, Bitcoin uses mechanisms
Bitcoin's Proof-of-Work (PoW) consensus mechanism is designed to make a block expensive, but cheap to verify that the block is valid.
Suppose someone tries to cheat with an invalid block. In this case, the network will immediately reject it and miners will not be able to recover their mining fees.
What Are Bitcoins Used For?
Bitcoin is primarily used as a digital asset and store of value. Anyone with an internet connection can send and receive them, and their digital presence means they can be transferred globally.
Bitcoin is sometimes used for more private transactions. The transaction is public, and the address (public key) is pseudonymous, although not completely anonymous. In other words, although transactions are visible on the blockchain, the users behind them are not easily identified.
Some people also buy bitcoin as a long-term investment, with the hope that its value will increase over time. Like gold or other commodities, bitcoin's limited supply and decentralized nature make it a great choice for investors looking to diversify their portfolio.
Bitcoin History
Bitcoin was first introduced in 2008 when Satoshi Nakamoto published a white paper entitled "Bitcoin: A Peer-to-Peer Electronic Cash System". This white paper introduces a new digital asset that will operate on a decentralized system without relying on governments or banking systems.
In January 2009, the Bitcoin protocol was released, and the first bitcoin transaction occurred between Satoshi Nakamoto and a programmer named Hal Finney. This transaction involved sending ten bitcoins from Nakamoto to Finney.
After the first transactions, more people started discovering Bitcoin and joining the network. The digital currency gained popularity among a small community of technology enthusiasts by demonstrating that Bitcoin could function without a central authority or intermediary.
Bitcoin Pizza was another important milestone in Bitcoin history, as it marked the first time bitcoin was used as a transaction in the real world.
On May 22, 2010, a programmer named Laszlo Hanyecz made history by using 10,000 bitcoins to buy two pizzas. This transaction became known as "Bitcoin Pizza Day" and is now celebrated annually on May 22.
Who created Bitcoin?
Satoshi Nakamoto's identity is still a mystery. Satoshi could be a person or a group of developers anywhere in the world.
His name is of Japanese origin, but his mastery of the English language leads many to believe that Satoshi came from an English-speaking country.

Did Satoshi invent blockchain technology?
Bitcoin combines a number of technologies that have been around for a long time, and this includes blockchain technology.
The use of these immutable data structures can be traced back to the early 1990s when Stuart Haber and W. Scott Stornetta proposed a system for timestamping documents. Just like today's blockchains, these systems rely on cryptographic techniques to secure data and prevent it from being tampered with.

How many bitcoins are there?
The protocol sets the maximum supply of bitcoin at 21 million coins. By 2023, more than 90% of that amount will have been mined, but it will take more than a hundred years to produce the rest.
This is caused by periodic events known as halvings, which gradually reduce miner rewards .
What is meant by Bitcoin Halving?
Bitcoin halving is a process that reduces the speed at which new Bitcoin blocks are created. Specifically, halving refers to periodic halving events that reduce the block rewards offered to miners.
Bitcoin's next halving is expected to occur in 2024, about four years after the last halving, which occurred in May 2020. Bitcoin halving is at the heart of its economic model because it ensures that coins are issued at a steady pace, getting harder at a predictable rate.
The controlled rate of monetary inflation is one of the main differences between crypto assets and traditional fiat currencies, which have essentially unlimited supply.

Is Bitcoin Safe?

One of the main risks associated with Bitcoin is the potential for hacking and theft. For example, in phishing scams , hackers use social engineering techniques to trick users into revealing their login credentials or private keys.
Once hackers have access to a user's account or crypto wallet , they can transfer the victim's bitcoins to their own wallet.
Another way that hackers can steal bitcoins is through malware or ransomware attacks. Hackers can infect a user's computer or mobile device with malware that allows them to access the user's Bitcoin wallet.
In some cases, hackers can also use ransomware to encrypt users' files and demand payment in bitcoin to unlock them.
Because bitcoin transactions cannot be reversed and are not insured by any government agency, users must take precautions to protect their bitcoin holdings. This includes using strong passwords, two-factor authentication, and storing bitcoins in secure crypto wallets that are inaccessible to hackers.
It is also important to only download Bitcoin-related software from trusted sources.
Another risk associated with bitcoin is price volatility . The value of bitcoin can fluctuate greatly in a short period of time, making it a risky investment for those unprepared for potential losses.
