Bitcoin is the world's first decentralized digital currency and has been making headlines since its inception in 2009.

Despite its popularity, many people still struggle to understand what Bitcoin is and how it operates. In this beginner's guide, we will explore the basics of Bitcoin, including its history, how it works, and its differences from traditional currencies.

What is Bitcoin?

Bitcoin, commonly referred to as BTC, is a digital or virtual currency, also known as cryptocurrency.

It was created by an unknown entity under the pseudonym Nakamoto in 2009 with the aim of creating a completely decentralized new currency, which means it will not be controlled by any government or financial institution. The birth of Bitcoin is also a response to the 2008 financial crisis, highlighting the demand for alternative and more resilient financial systems.

Bitcoin operates based on a technology called blockchain, which is a distributed digital ledger where all transactions are recorded and visible to everyone on the network. This transparency helps maintain the integrity of the system and makes it difficult for any fraudulent activities to occur.

Bitcoin is generated through a process called "mining," in which individuals use powerful computers to solve complex mathematical problems. The first person to solve the problem will receive rewards in the form of new Bitcoin, which will motivate more people to participate in the network. The system can also protect the network from attacks and maintain its security.

Bitcoin is stored in a digital wallet, which can be based on software or hardware devices. Bitcoin transactions are sent from one wallet to another, and each transaction is recorded on the blockchain. This makes Bitcoin transactions anonymous - although the transaction data is public, the identity of the person conducting the transaction is not.

Although Bitcoin has many advantages, it also faces challenges. Its highly volatile nature makes it a high-risk investment, and its use for illegal activities has raised concerns. In addition, due to the irreversibility of Bitcoin transactions, if Bitcoin is sent to the wrong address, it may result in permanent losses.

How does Bitcoin operate?

It is crucial to delve into the operation of Bitcoin and understand its operation on peer-to-peer networks, which are fundamentally decentralized. This means that Bitcoin is not issued, controlled, or regulated by any central institution such as the government or central bank, preventing it from government intervention or manipulation. Bitcoin transactions occur directly between users on the network without intermediaries participating. Each transaction is verified by network nodes through cryptography and recorded in a public ledger called blockchain.

Bitcoin miners add new transaction data to the blockchain. As a reward for their efforts, the miners will receive new Bitcoin rewards, thereby introducing new coins into circulation. This process ensures the security and integrity of the Bitcoin network.

In addition, Bitcoin operates based on both public and private keys. Your public key is similar to a bank account and is a wallet address that others can use to send Bitcoin to you. A private key is similar to your ATM password, which is a password that allows you to access and send Bitcoin. Ensuring the security of this private key is crucial, as losing it means you cannot access your Bitcoin.

How do you mine Bitcoin?

Extracting Bitcoin is a crucial process that involves using high-performance computers to solve complex mathematical problems, known as proof of effort. This process is crucial for the functionality and security of the Bitcoin network.

Miners, the individuals involved in this process, are committed to solving these problems, which are essentially protecting the encrypted "hashes" of each transaction block on the Bitcoin network. The miners who first solve the problem will receive rewards in the form of new Bitcoin, thereby motivating more people to participate in the network. This powerful system also helps to protect the network from potential attacks.

However, it is worth noting that Bitcoin mining is a challenging and resource intensive activity. It requires a high hash rate, measured in hashes per second (H/s), which represents the number of hashes that miners can calculate per second. In order to successfully mine Bitcoin, miners need a high hash rate, usually measured in megahashes per second (MH/s), gigabits per second (GH/s), or terahashes per second (TH/s).

The Bitcoin code provides miners with additional Bitcoin as a reward, encouraging them to continue competing, solving puzzles, and maintaining the entire system. The reward system is a way to add new transactions to the blockchain. However, mining rewards are roughly halved every four years, a process known as halving. This means that although miners received 50BTC for mining a block in 2009, the reward was reduced to 25BTC in 2012, then to 12.5BTC in 2016, and most recently to 6.25BTC in 2020. By 2140, it is expected that all Bitcoins will be released into circulation, allowing miners to profit from verification networks through transaction fees.

What is a Bitcoin wallet?

The Bitcoin wallet is essentially a digital storage system for Bitcoin. Just like a physical wallet, it holds your currency, but in this case, the currency is numerical. The wallet does not actually store your Bitcoin, but rather stores the private key you need to access Bitcoin addresses and sign transactions. Your wallet also has a public key, which is a public code that others can use to send Bitcoin to your wallet. It is worth noting that although your public key can be freely shared, your private key should be kept confidential and secure, as anyone with access to it can use your Bitcoin.

There are various types of Bitcoin wallets, including mobile wallets, network wallets, desktop wallets, hardware wallets, and paper wallets.

Mobile and online wallets are convenient and user-friendly, allowing you to access your Bitcoin from anywhere through an internet connection. A desktop wallet is a software application that you can download and install on your computer, providing a higher level of security than a network wallet. A hardware wallet is a physical device that can securely store private keys offline, protecting it from online threats. Finally, a paper wallet is a physical printout of your public and private keys, providing a secure way to store your Bitcoin offline.

Bitcoin wallets not only help store and manage your Bitcoin, but also enable you to send, receive, and monitor your transactions. When you want to send Bitcoin, you only need to enter the recipient's public key and the amount you want to send, and then sign the transaction with your private key. Once the transaction is confirmed, it will be recorded on the Bitcoin blockchain and the balance in your wallet will also be updated.

Despite its digital nature, using a Bitcoin wallet is as simple as using a traditional wallet, making it a tool that anyone interested in using Bitcoin can use.
