Taproot Upgrade Officially Locked In

The Taproot upgrade was officially locked in for activation after over 90% of miners signaled support during Speedy Trial.

This stage is kept distinct from nearby proposal, release, signaling, lock-in and activation stages. That separation is especially important in Bitcoin development, where code availability and network activation can occur months apart.

Placed in the broader 2021 chronology, the event helps show how Bitcoin was simultaneously becoming a subject of institutional finance, public policy, technology development and mass culture. Its inclusion reflects the specific historical development described above rather than a claim that every related market reaction was caused by this event alone.
