Pseudonymous cypherpunk Satoshi Nakamoto posted the document, titled Bitcoin: A Peer-to-Peer Electronic Cash System, to a cryptography mailing list, according to Cointelegraph. The paper was created to bypass opaque financial institutions and remove the need for trust in financial transactions. Cointelegraph reported that the Bitcoin network began operating when its genesis block was mined on January 3, 2009. [3][4]

The network relies on a proof-of-work consensus mechanism where miners solve computational puzzles to validate transactions and secure the chain. The protocol features a hard supply limit of 21 million bitcoins, with block reward halving events occurring roughly every four years until issuance ends around the year 2140. [14]

Cointelegraph reported that the cryptocurrency network now faces security risks, artificial intelligence threats, and quantum computing concerns. Additionally, Onramp chief executive Michael Tanguma stated to CoinDesk that business owners can protect part of their surplus by holding bitcoin. [2][3][4]
