The Technology That Transformed the Financial World: Bitcoin Turns 17

Bitcoin, the pioneer of the cryptocurrency market, has celebrated its 17th anniversary today.

The first block, known as the “genesis block,” released by Satoshi Nakamoto on January 3, 2009, marked the beginning of a technology that today has profound effects on the global financial system.

Satoshi Nakamoto added a striking message from The Times newspaper to the data of block #0, which launched the Bitcoin network: “03/Jan/2009 Chancellor prepares a second bailout for banks.” This statement, referencing The Times headline, symbolized a critical stance towards the banking system immediately following the 2008 global financial crisis. The Genesis block contained only a single transaction, and the block reward was set at 50 BTC.

At the time of writing, Bitcoin’s price is hovering around $90,011, while its total market capitalization exceeds $1.8 trillion.

Before Bitcoin, there were many initiatives in the digital currency field. ecash, developed by David Chaum in the 1980s, failed to gain widespread adoption due to its centralized structure. In the 1990s, Cynthia Dwork and Moni Naor proposed the idea that computational problems could generate value, while Adam Back developed Hashcash, a proof-of-work system, in 1997.

In 1998, Wei Dai (b-money) and Nick Szabo (bit gold), prominent figures in the cypherpunk movement, presented their ideas for distributed digital currencies. However, none of these projects were fully resistant to double-spending and Sybil attacks.

The Bitcoin.org domain was registered on August 18, 2008. On October 31, 2008, Satoshi Nakamoto shared a technical document titled “Bitcoin: A Peer-to-Peer Electronic Cash System” on a cryptography mailing list. Initially met with little interest in academic circles, this work, through a combination of diverse ideas, laid the foundation for a decentralized, Sybil-resistant, and Byzantine fault-tolerant digital currency system.

The Bitcoin software was released as open source, and the network officially launched on January 3, 2009. Nine days later, developer Hal Finney made the first Bitcoin transfer in history, receiving 10 BTC from Satoshi.
