On November 26, 1998, computer scientist and cryptographer Wei Dai published an essay on a Cypherpunk mailing list titled “B-Money: An Anonymous, Distributed Electronic Cash System”. This document described the foundation of a peer-to-peer payment system based on cryptography, laying the groundwork for what would become Bitcoin 10 years later.

25 Years Ago, Wei Dai Laid the Foundation for Bitcoin

Exactly 25 years ago, on November 26, 1998, computer scientist and cryptographer Wei Dai published a paper titled “B-Money: An Anonymous and Decentralized Monetary System”

The key idea of b-money was to use computing power as proof of work to create currency. Participants would create value by solving cryptographic problems, and this value could then be exchanged through anonymous transactions based on digital signatures.

Wei Dai also proposed decentralized governance and voting mechanisms to make decisions about the system’s rules. His visionary concepts thus laid the groundwork for a self-managed electronic currency, without the need for a central authority.

However, although revolutionary, the B-Money system conceived by Wei Dai never moved beyond the theoretical stage. It would take another decade before someone would pick up and materialize his concepts.

Bitcoin: The Realization of B-Money’s Vision

With Bitcoin, the decentralizing vision outlined in b-money would finally become a reality. Where Wei Dai’s project was just an outline, Bitcoin provided concrete solutions to the problems of double spending and sybil attacks. Most importantly, its blockchain technology offered a secure and transparent mechanism to record the history of transactions.

In fact, B-Money profoundly influenced the technical and philosophical design of Bitcoin:

  • Decentralized control through a peer-to-peer network,
  • Validation of transactions through distributed consensus,
  • User anonymity,
  • Absence of central authority or single issuer,
  • Currency creation based on proof of work.

Therefore, it’s no exaggeration to say that without the visionary work of Wei Dai, there might not have been a Bitcoin, at least not in its current form. Dai’s ideas thus fertilized the ground for the advent of the most famous cryptocurrency in 2008.

Is Wei Dai Satoshi Nakamoto?

The identity of Satoshi Nakamoto has spurred much speculation. In the face of this mystery, some have delved into the past of key figures from the early days of Bitcoin to find clues. Wei Dai has thus come under suspicion, being one of the few people informed by Satoshi during the initial months.

Yet, despite his conceptual influence on Bitcoin, there is no evidence to suggest that Dai and Nakamoto are one and the same. Dai has even stated that Satoshi had reinvented the notions of B-Money before discovering his work.

Regardless, the true Satoshi Nakamoto remains unidentified to this day, and his foundational innovation continues to thrive. Bitcoin thus follows its path, paved with the seminal ideas of B-Money from 25 years ago.

Beyond Bitcoin, thousands of cryptocurrencies have emerged, introducing real competition in currency issuance. The 2020-2022 pandemic also exposed the limitations of a centralized financial system, thereby strengthening public interest in decentralized cryptocurrencies.

These not only offer a savings alternative, but also the prospect of a more democratic and transparent future for global finance. Indeed, the market experiences turbulence, yet the movement initiated by Wei Dai’s vision of an emancipatory and decentralized digital world does not wane. It is likely just the beginning…
