Before Bitcoin, numerous pioneers explored the concept of electronic payment systems. However, only Bitcoin achieved ultimate success, while other projects fell short. A detailed examination of Satoshi Nakamoto’s approach to implementing Bitcoin reveals a process of tackling issues as they arose during development.
Although most of the technologies employed in Bitcoin were proposed over a decade earlier (1990+), Satoshi successfully integrated them by introducing the Proof of Work (PoW) + Nakamoto consensus mechanism. This article offers a comprehensive review of Bitcoin’s development process, providing readers with an intuitive understanding of the purpose of these technologies and the problems they aim to solve.
Bitcoin prehistory, 1974 – 2008
Revisiting the trailblazers of Bitcoin
In 1983, David Chaum first applied a digital signature to paper currency and developed blind signature technology to solve the double-spending problem. He established DigiCash, Inc. and patented his technology.
Many attribute Bitcoin’s success to its non-corporate, open-source community development model.
Adam Back devised Hashcash in 1997 as a solution to spam, using mathematical calculations to increase the cost of server resource abuse (PoW). Cynthia Dwork and Moni Naor initially proposed this concept in 1993, primarily to address spam. Bitcoin’s PoW is a direct adaptation of Hashcash, explicitly referenced in the white paper.
Later, Wei Dai proposed b-money in 1998, while Nick Szabo, the originator of smart contracts, suggested the concept of bit-gold in the same year. These projects closely resembled what eventually became Bitcoin, functioning as peer-to-peer networks. However, without a consensus mechanism, each node maintained its version of the ledger, unsynchronized with other transactions.
Satoshi’s unique approach to building and problem-solving involved writing code before formulating theories. This method differed from the typical academic approach of theorizing before implementing ideas. Satoshi believed that making the code public was necessary before detailing the theoretical specifics.
Bitcoin’s success highlights the significance of deductive methods, particularly first principles. In its early days, many professionals doubted Bitcoin’s viability, as previous attempts had failed. This skepticism stemmed from a lack of knowledge or unwillingness to explore the underlying details of Bitcoin.
