Before the term "Bitcoin" became synonymous with digital currency and financial transformation, the groundwork for its creation was laid by a series of ideas, innovations, and social movements. Among these, the cypherpunk movement stands out as a key element in the prehistory of Bitcoin.

In the heart of the technological evolution of the 1980s and 1990s, a group of people began to deeply question the role of privacy and freedom in the digital age. These individuals, who would later be known as "cypherpunks", firmly believed that cryptography could serve as a tool to protect individual rights against the interference from governments and large corporations.

Iconic figures such as Julian Assange, Wei Dai, Tim May, and David Chaum played a pivotal role in shaping the philosophy and vision of the movement. These thinkers shared their ideas on an influential mailing list, where participants from around the globe engaged in debates about the best ways to leverage technology for greater individual freedom.

The cypherpunk movement, deeply rooted in digital activism and cryptography, drew upon several foundational texts to articulate its principles and vision for the future. Among these writings, three stand out in particular:

written by Eric Hughes in 1993, asserts that privacy is a fundamental right. The author argues that the ability to communicate freely and confidentially is essential for a free society. The manifesto states: "We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy [...]. We must defend our own privacy if we expect to have any".

written by Timothy C. May in 1992, this document explains how the use of cryptography could lead to an era of cryptographic anarchy where governments would be powerless to interfere in the private affairs of citizens. May envisioned a future where people anonymously exchange information and money without the intervention of a third party.

although not exclusively cypherpunk, this text reflects the sentiments of many participants in the movement. Written in 1996 by John Perry Barlow, it is a response to the increasing regulation of the Internet by governments. The declaration asserts that cyberspace is a distinct realm from the physical sphere and should not be subject to the same laws. As it states, "We have no elected government, nor are we likely to have one".

Before the emergence of Bitcoin, there had been several attempts to create a digital currency. For example, David Chaum introduced the concept of "anonymous electronic money" with his project "DigiCash" in the 1980s. Unfortunately, due to various constraints, DigiCash never boomed.

Another important precursor is Wei Dai's "B-money". Although it was never implemented, it presented the idea of an anonymous digital currency where fraud detection was performed by a community of evaluators rather than a central authority.

The image below clearly illustrates the development of the movement through its many technological innovations.

It was in this fertile environment that the mysterious Satoshi Nakamoto published the Bitcoin whitepaper in 2008. In this document, he combined several ideas from the cypherpunk movement, such as proof of work and cryptographic timestamps, to create a decentralized and censorship-resistant digital currency.

However, Bitcoin was more than just that: it represented the achievement of the cypherpunk ideals. Beyond its technology, it symbolized a revolution against traditional financial systems and offered an alternative based on transparency, decentralization, and individual sovereignty.

The prehistory of Bitcoin is deeply rooted in the cypherpunk movement and the collective quest for greater freedom in the digital age. By combining the principles of cryptography, decentralization, and integrity, Bitcoin has become much more than a currency. In fact, it is the product of a philosophical and technological revolution that continues to reshape our world.

Therefore, Bitcoin is a protocol that stretches over long periods of time, and encourages us to question our relationship with energy, time, and money.

However, is Bitcoin a "real" currency? To understand this, we first need to understand the concept of money and its various forms, which we will explore in the next chapter.
