Reading Time: 4 minutes

1982: David Lee Chaum introduces the idea of digital cash and the blockchain protocol with his dissertation “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups.” Bloomberg would later refer to Chaum as the Godfather of Crypto.

1997: Adam Back, who reportedly discussed this idea as early as 1992, proposes a proof-of-work algorithm called HashCash that would later serve as the basis for Bitcoin mining.

November 1998: Wei Dai proposes the creation of B-money, an “anonymous, distributed electronic cash system” with a proof-of-work protocol, on the Cypherpunks mailing list. Back supposedly referred Bitcoin creator Satoshi Nakamoto to Wei’s work.

September 1999: An anonymous post on the same mailing list introduces an idea called “ecash” that bears similarities to Bitcoin, leading some to theorize that the author might have been a young Satoshi.

October 31, 2008: Satoshi Nakamoto, an anonymous person or group, posts the “Bitcoin: A Peer-to-Peer Electronic Cash System” paper to the Cypherpunks mailing list. This paper arguably served as a Declaration of Independence for decentralized finance.

January 3, 2009: Satoshi sends bitcoin to software developer Hal Finney. This resulted in the mining of the “Genesis Block” (or Block 0), marking the birth of Bitcoin and the start of the Bitcoin blockchain. Another transaction took place six days later, creating Block 1, with some suggesting the wait time was a nod to the six days of creation in The Book of Genesis.

November 18, 2013: During a U.S. Senate hearing, federal officials acknowledge that digital currency networks offer benefits for the financial sector, showing a growing awareness by the government that Bitcoin is more than a fad. That month, the value of Bitcoin rose sharply to a peak of $1,100, having started the year at $13.

December 18, 2013: HODL, an acronym for “Hold On for Dear Life,” is born after a semi-coherent Bitcointalk forum user types “I am hodling” in reference to “holding” Bitcoin. The typo sparked the creation of a phrase that would define a movement.

January 9, 2014: Overstock becomes the first major retailer to accept bitcoin, reportedly selling $124,000 in goods paid for with bitcoin in the first 21 hours. Microsoft, Dell, Expedia and other major retailers followed suit later that year.
