Sichuan Orders Bitcoin Mining Operations to Shut Down

Authorities in Sichuan ordered all cryptocurrency mining operations to shut down, marking the effective end of legal Bitcoin mining in China.

The historically important point is the procedural stage captured by this event: Sichuan Orders Bitcoin Mining Operations to Shut Down. The action affected Bitcoin directly where Bitcoin fell within the rule or market being discussed, while broader digital-asset language is not treated as Bitcoin-specific.

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.

The shutdowns drove Bitcoin's hashrate sharply lower and produced unusually slow blocks until the protocol's difficulty adjustment mechanism caught up. By early July, the network recorded its largest-ever downward difficulty adjustment, while later 2021 data showed mining capacity being re-established in other jurisdictions.
