Review of Bitcoin and how it works

Bitcoin is a digital currency designed as an asset out of command, and no entity or individual can be involved in its financial transactions. Instead, blockchain miners are rewarded for the work done to verify transactions and can be purchased on multiple exchanges. And this is the same process that causes bitcoin mining. Bitcoin was introduced to the public in 2009 by an anonymous developer or group of developers named Satoshi Nakamoto. Since then, this currency has become the most recognized digital currency in the world. Its popularity inspired the development of many other digital currencies. These competitors are either trying to replace it as a payment system or use it as a tool or security token in other blockchains and emerging financial technologies.

What is Bitcoin?

In August 2008, the domain name Bitcoin.org was registered. Today, this domain is WhoisGuard Protected, meaning that the identity of the person who registered it is not available to the public. In October 2008, a person or group using the name Satoshi Nakamoto announced on metzdowd.com: "We are working on a new electronic cash system that will be completely peer-to-peer and outside the control of any person or entity." The article, now published on Bitcoin.org, is titled "Bitcoin: A Peer-to-Peer Electronic Cash System. " On January 3, 2009, the first Bitcoin block was mined, Block 0. This block, also known as the "Genesis Block," is the second bank bailout. Bitcoin rewards are halved every 210,000 blocks. For example, the block reward was 50 new bitcoins in 2009. On May 11, 2020, the third halving took place, reducing the reward per block to 6.25 bitcoins. This process is called halving, and it happens once every 4 years. A bitcoin can be divided into eight decimal places (100 millionths of a bitcoin), and this smallest unit is called a satoshi.
If necessary, and if participating miners accept the change, Bitcoin can eventually be divided into even more decimal places. As a form of digital currency, Bitcoin is very modern and not very complicated technology. For example, if you have one bitcoin, you can use your cryptocurrency wallet to send smaller portions of that bitcoin as payment for goods or services.

Bitcoin blockchain technology

Digital currencies are part of a blockchain and the network needed to power it. Blockchain is a distributed ledger, a shared database that stores data. Encryption methods secure the data in the blockchain. When a transaction is done in the blockchain, the information of the previous block is copied and encrypted with the new data in the new block, and the transaction is verified by validation devices called miners in the network.

When a transaction is confirmed, a new block is opened, and a bitcoin is created. This bitcoin is then rewarded to the miner(s) who have verified the data within the block, which they can then use, hold or sell. Bitcoin uses the SHA-256 algorithm to encrypt data stored in blocks on the blockchain. In simpler terms, the transaction data stored in a block is encoded into a 256-bit hexadecimal number. This number contains all the transaction data and information related to the blocks before that block.
Transactions are placed in a queue to be verified by miners on the network. Miners on the Bitcoin blockchain network all try to confirm a transaction simultaneously. Mining software and hardware work to resolve the nonce, a four-byte number contained in the block header that miners attempt to resolve. The block header is repeatedly hashed or randomly regenerated by a miner until it reaches a target number specified by the blockchain. When this process is complete, a new block will be created to encrypt and verify further transactions.

How does Bitcoin work?

It is essential to understand the three distinct components of Bitcoin. These components combine to create a decentralized payment system:

• Bitcoin network

•Bitcoin digital currency, called (BTC)

• Bitcoin blockchain

Bitcoin network

Bitcoin runs on a peer-to-peer network where users, usually individuals or entities, who want to exchange Bitcoin with others on the network do not need the help of intermediaries to complete and confirm transactions. Instead, users can choose to connect their computer directly to this network and record all historical Bitcoin transactions.

Bitcoin blockchain

Blockchain technology allows cryptocurrency transactions to be verified, stored, and ordered immutable and transparently. Credit immutability and transparency are critical for a payment system that relies on zero trust. The network updates each user's version to reflect the latest changes whenever new transactions are confirmed and added to the blockchain.

As the name suggests, the Bitcoin blockchain is a digital series of chronologically ordered "blocks," pieces of code that contain Bitcoin transaction data. However, it is important to note that transaction validation and Bitcoin mining are separate processes. Whether or not transactions are added to the blockchain, mining can still occur. Likewise, the intensity of Bitcoin transactions does not necessarily increase the rate at which miners find new blocks.

Regardless of the volume of transactions awaiting confirmation, Bitcoin is programmed to allow new blocks to be added to the blockchain approximately every 10 minutes. Due to the public nature of the blockchain, all participants in the network can track and evaluate Bitcoin transactions in real-time. This infrastructure reduces the possibility of an online payment issue known as double-spending. Double spending occurs when a user tries to spend the same cryptocurrency twice. In the traditional banking system, double costs are avoided. You also don't overpay with physical cash because you can't hand two people a $1 bill.

However, Bitcoin has thousands of copies of a blockchain and therefore requires the entire network of users to agree on the validity of every Bitcoin transaction. This agreement between all parties is what is known as "consensus." As banks constantly update their user balances, anyone who owns a copy of the Bitcoin blockchain is responsible for verifying and updating the balances of all Bitcoin holders. So, the question is: How does the Bitcoin network ensure that consensus is achieved? This is done through a process called "proof of work."

How does Bitcoin help you earn money?

The network of Bitcoin miners earn money by successfully validating blocks and receiving rewards from Bitcoin. Bitcoins can be exchanged for fiat currency through cryptocurrency exchanges and used to make purchases at merchants and retailers that accept them. Likewise, investors and speculators can earn money by buying and selling Bitcoin.

What are the problems with Bitcoin?

There have been several criticisms of Bitcoin, including that the mining system is extremely energy-hungry and consumes much energy. Digital currencies, including Bitcoin, are also a platform for fraud and can be used for black market transactions. Cash has provided this functionality for centuries, and the Bitcoin blockchain may actually be a tool for law enforcement.

How to invest in Bitcoin?

One of the ways to invest in Bitcoin is to mine it. But if you don't want to mine Bitcoin, it can be purchased using a cryptocurrency exchange. Most people can't buy 1 Bitcoin because of its high price, but you can purchase parts of Bitcoin on these exchanges for fiat currencies like US dollars. For example, you can buy bitcoins on Coinbase or other reputable exchanges by creating an account and funding it. You can top up your account using your bank account or credit card.

Is Bitcoin a good investment?

Bitcoin has experienced extreme fluctuations, especially in the last two years. Whether this is a good investment depends on your financial profile, investment portfolio, risk tolerance, and investment goals. You should always consult a financial professional for advice before investing in cryptocurrencies to make sure the conditions are right for you.
