What is Bitcoin: 10 Essential Things You Need to Know

What is Bitcoin? It’s a digital asset, often referred to as ‘coins,’ with ownership recorded on a decentralized electronic ledger known as Bitcoin’s blockchain. This ledger is continually updated on approximately 10,000 independently operated computers worldwide, which communicate and synchronize. Transactions, representing the transfer of ownership of these coins, are generated and validated according to a protocol—a set of rules that govern the ledger’s updates and operation.


An In-Depth Look at the Revolutionary Digital Asset

Bitcoin is a revolutionary digital asset that operates on a decentralized network of computers around the world. It is a form of digital currency that is not controlled by any government or financial institution, but rather by its users who collectively maintain the network. The ownership of bitcoins is recorded on an electronic ledger known as the blockchain, which is constantly updated and validated by independent nodes on the network.

Transactions that record the transfer of bitcoins are created and verified according to a set of rules that make up the Bitcoin protocol. These rules ensure that the network is secure and that the ledger is accurate and up-to-date. Bitcoin’s blockchain technology has the potential to disrupt traditional financial systems and has already shown to be a reliable and secure way to transfer value globally.

The decentralized nature of Bitcoin

The decentralized nature of Bitcoin means that it is not subject to the same inflationary pressures as fiat currencies. The finite supply of 21 million bitcoins means that it is inherently deflationary, and as demand for the digital asset increases over time, its value may continue to appreciate. Additionally, the use of cryptography ensures that Bitcoin transactions are secure and private, making it an ideal alternative for those who value financial privacy.

In conclusion, Bitcoin is a revolutionary digital asset that has the potential to change the way we think about money and finance. Its decentralized and secure nature, along with its finite supply, make it an attractive alternative to traditional currencies. As the world becomes more digital and interconnected, Bitcoin and its blockchain technology will likely continue to play an increasingly important role in the global economy.

Bitcoins are a decentralized digital currency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. Bitcoins are based on a blockchain, which is a decentralized public ledger that records all transactions and allows for secure peer-to-peer transactions without the need for a central authority, Bitcoins can be obtained through a process called mining, where powerful computers solve complex mathematical equations to validate transactions and earn new bitcoins as a reward. Alternatively, bitcoins can be purchased through cryptocurrency exchanges or received as payment for goods and services.

One of the key features of bitcoins is their decentralized nature, which means they are not controlled by any government or financial institution. This makes bitcoins an attractive option for individuals looking to store value or make transactions without the need for a middleman.

Potential investment

Bitcoins are also known for their potential as an investment, with many investors buying and holding bitcoins in the hopes of profiting from price appreciation. However, bitcoins are also known for their volatility, with prices often experiencing significant fluctuations over short periods of time.

The protocol is implemented by software—an app—that participants run on their computers. The machines running the apps are called ‘nodes’ of the network. Each node independently validates all pending transactions wherever they arise, and updates its own record of the ledger with validated blocks of confirmed transactions. Specialist nodes, called miners, bundle together valid transactions into blocks and distribute those blocks to nodes across the network.

Anyone can buy bitcoins, own them, and send them to other people.

Every Bitcoin transaction is recorded and shared publicly in plain text on Bitcoin’s blockchain. Contrary to many media articles, Bitcoin’s blockchain is not encrypted. By design, everyone sees all details of all transactions. Anyone can, in theory, create bitcoins for themselves too.

This is part of the block creation process, called mining, and is described later.

What Is Bitcoin ?

The purpose of Bitcoin is described in its whitepaper—a short document written by a pseudonymous Satoshi Nakamoto, published in October 2008 It describes why Bitcoin exists and how it should work. It is worth reading the whitepaper in full. It is only nine pages long and available online. The abstract says:

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double spending. We propose a solution to the double spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.

The network requirements

As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, theyll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

That first sentence says it all. It sets out the purpose of Bitcoin, and how Bitcoin derives both value and utility. For the first time in history, we have a system that can send value from A to B, without the physical movement of items or using specific third-party intermediaries. It is difficult to overstate how important a milestone this is in the evolution of payments. I get shivers down my spine every time I think of Bitcoin like this. As popularized by cryptocurrency industry commentator Tim Swanson, Bitcoin is designed as censorship resistant digital cash.

There is no mention of a blockchain or ‘block chain’ at all in the original Bitcoin whitepaper, even though we are constantly reminded by the media that Bitcoin is built on blockchain or that blockchain is the underlying technology of Bitcoin. A chain of blocks was not the purpose of Bitcoin, it is just the design that was developed to achieve the objective —the solution to the business problem.

How Does Bitcoins Work?

The Bitcoin blockchain is managed by software running on computers that communicate with each other forming a network. Although multiple compatible software implementations exist, the most commonly used software is called ‘Bitcoin Core’ and source code to this software is published on GitHub. This software contains the full range of functionalities needed for the network to exist.

Bitcoin blockchain software tasks:

It has the ability to perform the following tasks which will be explained later:

  • Connect with other participants in the Bitcoin network
  • Download the blockchain from other participants
  • Store the blockchain
  • Listen for new transactions
  • Validate those transactions
  • Store those transactions
  • Relay valid transactions to other nodes
  • Listen for new blocks
  • Validate those blocks
  • Store those blocks as part of its blockchain
  • Relay valid blocks
  • Create new blocks
  • ‘Mine’ new blocks
  • Manage addresses
  • Create and send transactions

However, in practice, the software is usually only used for its bookkeeping function, which will be explained in depth in this section.

Bitcoins works

To understand how Bitcoins works, and why it works the way it does, it is important to keep in mind the objective: to create an electronic payment system that cannot be censored, and to allow anyone the ability to send payments ‘directly from one party to another without going through a financial institution’.

Such a system cannot have a central administrator managing the ledger, as that administrator would be the financial institution that Bitcoin is set up to avoid. The system therefore needs to be able to be operated by anyone, without any need to identify themselves or gain permission from a gatekeeper. The moment that parties need to identify themselves, they lose privacy and are vulnerable to interference, coercion, prison, or worse. This goes for both administrators of the system and users themselves. So every single part of the solution needs to work with these constraints in mind.

How did Satoshi go about designing the solution? Let’s start with a classic centralized model and then try to decentralize it. In this way, we can build up the design of Bitcoin step by step.

The Unique and Surprising Features

One unique aspect of Bitcoin is its limited supply. Unlike traditional fiat currencies that can be printed on demand, Bitcoin has a predetermined supply cap of 21 million coins. This means that the total number of Bitcoins that will ever exist is limited, and this limit is hard-coded into the Bitcoin protocol.

As of now, more than 18.7 million Bitcoins have already been mined, leaving less than 2.3 million to be mined. The mining of new Bitcoins is designed to slow down over time, and the last Bitcoin is expected to be mined around the year 2140.

This limited supply makes Bitcoin deflationary in nature, meaning that as demand for Bitcoin increases, its value may continue to appreciate over time. This is because the supply of Bitcoin is fixed, but its demand is subject to market forces such as speculation, adoption, and the use cases of the currency.

This is in contrast to traditional fiat currencies that are inflationary in nature, where central banks can print new currency to stimulate economic growth. While inflationary monetary policies may help boost economic growth, they can also lead to devaluation and loss of purchasing power over time.

In summary, Bitcoin’s limited supply creates a unique dynamic that is different from traditional currencies. As demand for Bitcoin increases, its value may continue to appreciate over time, making it an attractive investment option for those looking to diversify their portfolio.

The Fascinating World of Bitcoin: Exploring Its Unique Features and Benefits

Another unique feature of Bitcoin is its decentralized nature. Unlike traditional fiat currencies that are controlled by central authorities such as banks or governments, Bitcoin is not controlled by any central authority or institution. Instead, it operates on a decentralized network of computers around the world, with each computer running the Bitcoin software acting as a node in the network.

This means that no single entity can control the supply of Bitcoin or manipulate its value, making it more resistant to inflation, corruption, or other forms of manipulation. Additionally, the decentralized nature of Bitcoin allows for greater privacy and security in transactions, as users are not required to reveal their personal identities in order to make or receive payments.

Blockchain technology

The decentralized nature of Bitcoin is achieved through the use of blockchain technology, which is a distributed ledger system that records and validates all Bitcoin transactions in a secure and transparent manner. Every time a Bitcoin transaction is made, it is recorded on the blockchain and validated by other nodes in the network, ensuring its authenticity and preventing double-spending.

Overall, the decentralized nature of Bitcoin is one of its most unique and compelling features, as it allows for greater financial freedom, privacy, and security for users around the world.

Another unique feature of Bitcoin is its pseudonymous nature. While all transactions on the Bitcoin network are recorded on the public blockchain, users are identified only by their wallet addresses, which are essentially a series of randomly generated characters. This provides a degree of anonymity to users, as their real-world identity is not directly linked to their transactions. However, it’s worth noting that Bitcoin transactions can still be traced and analyzed through various means, including blockchain analysis tools and third-party data sources.
