Review of Cryptocurrency Bitcoin (BTC)

History of Bitcoin

Bitcoin was created in 2009 by an anonymous individual or group using the pseudonym Satoshi Nakamoto. It represents the first decentralized cryptocurrency operating on blockchain technology. The core idea was to create digital money that could function without central authority and allow users to transact directly with each other.

Key Milestones in Bitcoin's Creation

• 2008: Nakamoto publishes a white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System," outlining the concept of Bitcoin and its technical aspects.
• 2009: The first Bitcoin block (the genesis block) is mined, and the mining process begins. In the same year, the first transaction took place between Nakamoto and programmer Hal Finney.
• 2010: Bitcoin begins to gain popularity. The first commercial transaction using Bitcoin occurs when programmer Laszlo Hanyecz buys two pizzas for 10,000 BTC.
• 2011: The first services and exchanges for buying and selling Bitcoin emerge. The cryptocurrency starts to be used on various forums and websites.
• 2013: Bitcoin experiences significant price growth, attracting media attention and investors. At this stage, the first major exchanges for trading BTC appear.
• 2017: Crypto hits an all-time high and enters mainstream culture. Bitcoin becomes a topic of discussion at all levels, including government bodies and financial institutions.
• 2020: Bitcoin continues to grow in popularity, with increasing institutional investment and recognition from major companies.

Key Figures

Satoshi Nakamoto remains an enigmatic figure in the world of cryptocurrencies. Despite actively participating in the development of Bitcoin in its early years, their identity has yet to be revealed. Since 2010, Nakamoto has not been involved in the project, handing over management to other developers.

Other key figures in the history of Bitcoin include:

Since its inception, Bitcoin has evolved from an innovative technology into a recognized global currency. In 2021, Bitcoin became the first medium of exchange to be legalized as legal tender in some countries, such as El Salvador. It is accepted not only by individual users but also by major companies, confirming its status as a new asset and store of value.

Despite price fluctuations and associated risks, Bitcoin continues to attract the attention of investors and researchers, offering new opportunities for use in various sectors of the economy.

Bitcoin Technology

Bitcoin operates on blockchain technology, which is a distributed ledger that stores information about all transactions on the network. Each block in the blockchain contains a list of transactions, a timestamp, and a link to the previous block, ensuring data integrity and protecting it from tampering.

Principles of Blockchain Operation

The main principle of blockchain operation lies in its decentralized nature. All network participants (nodes) have access to the same version of the ledger, which prevents data manipulation. When a new block is added to the chain, it must be confirmed by the majority of nodes, making the system resistant to attacks and fraud.

Each block contains the following information:

• Transaction List: All transactions executed since the last block was instantly created.
• Previous Block Hash: This ensures the chain's continuity and makes it impossible to alter information in existing blocks.
• Current Block Hash: A unique identifier generated based on all block data.
• Timestamp: Indicates the time the block was created.

SHA-256 Algorithm

To ensure data security and integrity in the Bitcoin blockchain, the SHA-256 (Secure Hash Algorithm 256-bit) algorithm is used. This algorithm converts input data into a unique fixed-length string (256 bits). Key features of SHA-256 include:

• Irreversibility: It's impossible to reconstruct the original data from its hash.
• Collision Resistance: It's highly improbable that two different datasets will produce the same hash.
• Computational Speed: The algorithm enables rapid processing of large data volumes.

The Role of Mining

Mining is a crucial process in the Bitcoin network, as it facilitates both the creation of new Bitcoin and the validation of transactions. Miners leverage the computational power of their devices to solve complex mathematical problems related to block hashing. For successfully adding a new block to the blockchain, miners receive a reward in the form of new Bitcoin and transaction fees.

The mining process involves the following stages:

1. Collecting transactions into a pool and forming a block.
2. Calculating the block's hash using the SHA-256 algorithm.
3. Finding a value that makes the block's hash fall below a predetermined difficulty target (proof-of-work).
4. Adding the block to the blockchain after confirmation by other network nodes.

Thus, Bitcoin technology is based on a combination of a decentralized ledger, a robust hashing algorithm, and active miner participation, making it secure and attack-resistant.
