Frequently Asked Questions about Bitcoin, cryptocurrencies and Blockchain

What is Bitcoin?

Bitcoin is a decentralized digital currency that is based on a peer-to-peer network. It is created and held electronically, and it operates without a central bank or single administrator. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin is unique in that it is limited in supply, with only 21 million bitcoins ever to be created. It was created in 2009 by an unknown person or group using the name Satoshi Nakamoto, and it has since become the most widely used cryptocurrency in the world.

Bitcoin has gained popularity due to its decentralized nature, its ability to bypass traditional financial institutions, and its potential for anonymity. However, its volatility, lack of regulation, and association with illegal activities have also made it controversial.

What are cryptocurrencies?

Cryptocurrency is a type of digital currency that uses cryptography to secure and verify transactions and to control the creation of new units. Unlike traditional currency, which is controlled by governments or financial institutions, cryptocurrencies are decentralized, meaning they operate independently of any central authority.

The most well-known and widely used cryptocurrency is Bitcoin, which was created in 2009. Bitcoin operates on a blockchain, which is a decentralized ledger that records all transactions in a transparent and secure manner. The blockchain is maintained by a network of computers around the world, which work together to verify and record transactions.

Other popular cryptocurrencies include Ethereum, Ripple, Litecoin, and Bitcoin Cash. Each cryptocurrency has its own unique features and characteristics, but all are based on the same underlying technology of blockchain and cryptography.

Cryptocurrencies are often used as a means of payment for goods and services, and can also be traded on exchanges like traditional currencies or commodities. Because cryptocurrencies are decentralized and operate independently of central authorities, they are often seen as a way to protect against inflation, government interference, and other economic uncertainties. However, they are also subject to their own unique risks, such as market volatility and the potential for fraud and hacking.

What is Blockchain ?

At a high level, a blockchain is a decentralized, distributed ledger that records transactions in a secure and verifiable way. It was first introduced in 2008 as the underlying technology behind Bitcoin, but has since been adopted by many other cryptocurrencies and applications.

The key feature of a blockchain is its immutability. Once a transaction is recorded on the blockchain, it cannot be altered or deleted. This is accomplished through a process called consensus, where multiple nodes in the network come to agreement on the validity of the transaction before it is added to the blockchain.

In a blockchain network, every node has a copy of the entire ledger, which is constantly updated and synchronized with other nodes in the network. Transactions are grouped together into blocks, which are then added to the chain in a linear, chronological order.

Each block contains a cryptographic hash of the previous block, which links them together in a chain. This creates a tamper-proof record of all transactions that have occurred on the network, and ensures that any attempt to alter or delete a transaction would be immediately detected.

In addition to being secure and immutable, blockchains are also transparent and decentralized. Anyone can view the contents of the blockchain, and there is no single entity in control of the network. This makes it an ideal technology for a wide range of applications beyond just cryptocurrency, such as supply chain management, voting systems, and more.

What is a Crypto wallet ?

In the context of cryptocurrencies, a wallet is a software program or hardware device used to store, manage, and transact digital assets such as Bitcoin, Ethereum, and other cryptocurrencies.

A cryptocurrency wallet works similarly to a traditional physical wallet, allowing users to store their digital currency and use it to make transactions. However, instead of holding physical cash, a cryptocurrency wallet stores a user’s private keys, which are needed to access their cryptocurrency holdings and authorize transactions.

There are several types of cryptocurrency wallets, including desktop wallets, mobile wallets, online wallets, and hardware wallets. Each has its own benefits and drawbacks, and users should carefully consider their needs and security preferences when selecting a wallet. It’s important to note that while cryptocurrency wallets offer a high degree of security, they are not immune to hacks or theft, so it’s essential to take appropriate measures to protect your digital assets.

What is a crypto exchange ?

A crypto exchange is a platform that allows users to buy, sell, and trade cryptocurrencies with other users or the exchange itself. These exchanges typically require users to create an account, provide personal and financial information, and may also require identity verification.

Crypto exchanges operate similarly to traditional stock exchanges, with buy and sell orders matched between buyers and sellers. The price of cryptocurrencies on an exchange is determined by supply and demand, and can fluctuate rapidly.

Crypto exchanges may also offer additional services such as margin trading, lending, and staking, as well as access to a variety of different cryptocurrencies. However, it is important to note that crypto exchanges can be vulnerable to hacking and security breaches, so it is important for users to carefully research and choose a reputable exchange and take steps to secure their accounts and assets.

Who is Satoshi Nakamoto?

Satoshi Nakamoto is the pseudonym used by the unknown person or group of people who created the cryptocurrency, Bitcoin, and authored its original white paper in 2008. Their true identity has never been revealed and remains a mystery. Satoshi Nakamoto is believed to be a highly skilled computer programmer with expertise in cryptography and has created one of the most significant innovations in the field of finance and technology. Despite the anonymity, the contributions of Satoshi Nakamoto have had a profound impact on the development of the cryptocurrency industry, and their identity remains an object of fascination for many people.

The true identity of Satoshi Nakamoto, the pseudonymous creator of Bitcoin, is still unknown. Over the years, there have been several individuals who have been identified as potential candidates, based on various pieces of evidence and speculations. Some of the most notable candidates include:

Dorian Nakamoto: In 2014, Newsweek published an article claiming that a man named Dorian Nakamoto, who lived in California, was the creator of Bitcoin. However, Dorian Nakamoto denied any involvement in Bitcoin and claimed that he misunderstood the question that was asked of him.
Craig Wright: In 2016, an Australian computer scientist named Craig Wright claimed that he was the real Satoshi Nakamoto. However, his claims were met with skepticism and he has failed to provide conclusive evidence to support his claims.
Nick Szabo: Nick Szabo is a computer scientist and cryptographer who has been linked to the creation of Bitcoin due to his work on a precursor to Bitcoin called “bit gold.” However, Szabo has denied being Satoshi Nakamoto.
Hal Finney: Hal Finney was an early Bitcoin user and developer who worked on the Bitcoin code with Satoshi Nakamoto in the early days of the project. Some people have speculated that Finney may have been Satoshi Nakamoto, but there is no conclusive evidence to support this theory.

Overall, the true identity of Satoshi Nakamoto remains a mystery and may never be revealed.

What is an NFT ?

An NFT, or non-fungible token, is a unique digital asset that is verified using blockchain technology. Unlike traditional cryptocurrencies such as Bitcoin, which are interchangeable with one another and have the same value, each NFT is one-of-a-kind and cannot be replicated. NFTs are used to represent a wide range of digital assets, such as art, music, videos, and more. They are often bought and sold on online marketplaces, and their value is determined by supply and demand, similar to other collectibles. Because they are unique and verifiable, NFTs are seen as a way to establish ownership and authenticity in the digital world.

Here are some examples of popular NFTs:

CryptoPunks – a collection of 10,000 unique 8-bit characters, each with its own distinct traits and attributes.
Beeple’s “The First 5000 Days” – a digital art piece consisting of 5,000 unique images created by artist Mike Winkelmann, also known as Beeple.
NBA Top Shot – a digital collectibles platform that allows users to buy, sell, and trade officially licensed NBA highlights, with each highlight being a unique NFT.
Axie Infinity – a blockchain-based game that allows players to buy, sell, and trade NFT creatures called “Axies” and use them to battle other players.
Art Blocks – a platform for generative art, where users can purchase unique algorithmically-generated art pieces as NFTs.

Pudgy Penguins – a collection of 8,888 unique NFTs featuring cartoon penguins, each with its own distinct traits and attributes.
The Fidenza Collection – a collection of 1,001 unique algorithmically-generated NFTs created by artist Tyler Hobbs.

What is Ethereum?

Ethereum is a decentralized, open-source blockchain platform that enables developers to build decentralized applications (dApps) and smart contracts. It was launched in 2015 by Vitalik Buterin, a Russian-Canadian programmer, and a group of co-founders.

Ethereum is built on a blockchain technology that enables developers to create and deploy decentralized applications. It introduced the concept of smart contracts, which are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. This enables transactions to be performed without the need for intermediaries, such as banks or other financial institutions.

One of the key differences between Ethereum and other blockchain platforms is its use of the Ethereum Virtual Machine (EVM). The EVM is a runtime environment that enables developers to run smart contracts on the Ethereum blockchain.

Ethereum also has its own cryptocurrency, called Ether (ETH), which is used to pay for transaction fees and computational services on the Ethereum network.
