What is Bitcoin (BTC)?

Bitcoin is a decentralized digital currency that was first proposed in a 2008 whitepaper by an individual or a group of individuals using the pseudonym Satoshi Nakamoto. The cryptocurrency was officially launched in January 2009, following the publication of its whitepaper.

As a peer-to-peer online currency, Bitcoin allows transactions to occur directly between equal, independent participants without any intermediaries, such as banks or financial institutions. The goal of Bitcoin, as stated by Nakamoto, is to enable "online payments to be sent directly from one party to another without going through a financial institution."

Who Founded Bitcoin?

The true identity of Satoshi Nakamoto, the person or group behind the creation of Bitcoin, remains unknown as of 2021. On October 31, 2008, Nakamoto published the Bitcoin whitepaper, which detailed the concept of a decentralized digital currency built on a peer-to-peer network.

On January 3, 2009, Nakamoto mined the first block on the Bitcoin network, known as the genesis block, thereby launching the world's first cryptocurrency. The first known commercial transaction involving Bitcoin took place on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas, an event now celebrated as "Bitcoin Pizza Day."

Bitcoin Circulation and Supply

Bitcoin's total supply is limited to 21 million coins, a cap that is built into its software. New coins are created through a process called "mining," in which miners validate transactions and add them to the blockchain in the form of blocks. As a reward for their efforts, miners receive a predetermined number of new Bitcoins for each block they successfully mine.

When Bitcoin was first launched, the mining reward was 50 Bitcoins per block. This reward is halved approximately every four years, with the current reward standing at 6.25 Bitcoins per block.

How is the Bitcoin Network Secured?

The Bitcoin network is secured using the SHA-256 algorithm, a member of the SHA-2 family of cryptographic hashing algorithms. This same algorithmis also employed by Bitcoin's fork, Bitcoin Cash (BCH), as well as several other cryptocurrencies.

Bitcoin as a Store of Value

One of Bitcoin's primary functions is its use as a decentralized store of value. This means that it can serve as a digital asset that represents ownership rights, similar to physical assets or traditional units of account. However, the notion of Bitcoin as a store of value has been a subject of debate among experts and enthusiasts.

Bitcoin Technology Upgrades

Bitcoin's technology can be upgraded through two primary methods: hard forks and soft forks. A hard fork entails a radical change to the protocol that renders previously invalid blocks or transactions valid, necessitating all users to upgrade their software. In contrast, a soft fork involves changes to the protocol that only invalidate previously valid blocks or transactions, making it backward-compatible as old nodes will still recognize new blocks as valid.

Examples of notable cryptocurrencies that have undergone hard forks include Bitcoin's hard fork that resulted in Bitcoin Cash and Ethereum's hard fork that led to Ethereum Classic.

BRC20 Standard 2023

The BRC20 standard introduces token creation and transfer capabilities to the Bitcoin network(BRC20), utilizing the Ordinals protocol and Taproot upgrade. This enables new applications like DeFi on Bitcoin, expanding its use beyond just a digital currency. For the latest coins added check the CoinRotator BRC20 coinscreener.

The Lightning Network

The Lightning Network is an off-chain, layered payment protocol that enables instantaneous, high-volume, and trustless transactions between any two parties. By operating bidirectional payment channels, the Lightning Network allows for rapid reconciliation and private transactions. This innovation scales the transaction capacity of the Bitcoin network without incurring the costs associated with on-chain transactions and interventions.

Team Background: Origins and Key Contributors

Bitcoin's development has been driven by a diverse and dedicated global community of programmers, researchers, and enthusiasts. While the true identity of Satoshi Nakamoto, Bitcoin's creator, remains unknown, several key figures have emerged as important contributors to the project since its inception. Among them, Gavin Andresen played a significant role after being handed control of the network alert key and code repository by Nakamoto. Additionally, the Bitcoin source code repository on GitHub lists more than 750 contributors, underlining the collective efforts behind the continuous improvement and evolution of the cryptocurrency.

Current and Upcoming Project Developments: Enhancing Scalability and Usability

As Bitcoin gains traction, its developers continuously innovate to maintain a resilient and scalable network. The Lightning Network, for instance, optimizes transaction speed and volume through off-chain, trustless exchanges. Additionally, soft and hard forks serve as key protocol updates.

Bitcoin Price Analysis

As of July 18 2025 Bitcoin has a marketcap of $2.4T. This is {{percentagefromath}} from its all time high of $122.838K. In terms of its tokenomics, there's a total supply of 20M with 100% currently outstanding. Keep in mind Bitcoin has a fully diluted value of $2.4T which many investors might interpret as overvalued.
