🧠 How Did We Get to Bitcoin? This timeline traces the evolution of the core ideas behind Bitcoin — not just the launch itself in 2009, but the decades of breakthroughs that made it possible.
The infographic maps out key concepts like: 🔸 Linked timestamping 🔸 Proof of work 🔸 Public key cryptography 🔸 Smart contracts 🔸 Byzantine fault tolerance 🔸 Peer-to-peer networks
It starts in the 1970s with early cryptography work and runs through milestones like: 🟢 Diffie & Hellman’s 1976 paper on public-key crypto 🔴 Haber & Stornetta’s 1991 research on timestamping 🟣 Adam Back’s Hashcash (1997) 🔵 Nick Szabo’s smart contracts (1997) 🟠 The Cypherpunks movement and early digital cash attempts 🟤 Bitcoin’s 2008 whitepaper and 2009 launch ⚫ Ethereum’s rise and the emergence of proof-of-stake chains
You’ll also spot major forks, regulatory moments, and projects that carried these ideas forward. It’s all in one place — a dense but clear map of how cryptographic theory, digital rights activism, and open-source code led to a monetary revolution.
