HashCash 1997 (HASHCASH): Hashcash — 1997 Created by cryptographer Adam Back, Hashcash was originally designed to fight email spam and denial-of-service attacks by requiring a small amount of computational work before sending messages. This introduced the concept of Proof of Work (PoW) — work that is costly to produce but easy to verify. While not created as a digital currency, Hashcash later became one of Bitcoin’s key technical foundations, forming the basis of its mining system. The idea itself traces back to earlier research such as the 1992 paper “Pricing via Processing or Combatting Junk Mail.” Today, many proof-of-work cryptocurrencies still carry traces of Hashcash, making it one of the earliest and most enduring building blocks of modern crypto. https://bitcointalk.org/index.php?topic=245722.msg2605637#msg2605637
