On this day in 2011, Amir Taaki published BIP 1 — the very first Bitcoin Improvement Proposal — establishing the formal process by which anyone could propose changes to the Bitcoin protocol.
Modeled after Python's PEP process, the BIP system gave Bitcoin a structured way to evolve through community consensus rather than top-down decisions.
Every major upgrade since — from P2SH to SegWit to Taproot — has gone through this process.
