October 31, 2026 marks exactly 18 years since Satoshi Nakamoto published the Bitcoin whitepaper, "Bitcoin: A Peer-to-Peer Electronic Cash System," on October 31, 2008. The foundational document outlined a decentralized digital currency using proof-of-work and a distributed ledger to solve the double-spending problem without requiring trusted intermediaries. The anniversary highlights Bitcoin's evolution from an obscure cryptography mailing list post into a global asset class with a market capitalization exceeding hundreds of billions of dollars, institutional adoption through spot ETFs, and recognition as a store of value by sovereign entities and corporations worldwide.
