The Migration of Hashrate

A network moves through machines

China’s 2021 mining restrictions drove a sharp fall in reported Bitcoin hashrate and a rapid relocation of equipment and firms. The protocol did not need a migration policy. Machines were sold, shipped, warehoused, restarted, or abandoned as owners searched for electricity, legal tolerance, capital, and operating partners elsewhere.

A clean graph hides a rough journey

Network charts can show total hashrate falling and recovering. They cannot identify every physical machine behind an IP address, distinguish ownership from location, or record the price at which equipment was liquidated. A smooth global recovery can contain bankrupt sellers, stranded workers, emergency power contracts, and communities receiving new load.

Geography returns through energy

Mining is digitally coordinated but materially local. It competes for generation and grid capacity, responds to tariffs, creates some jobs, and can leave quickly when conditions change. The same megawatt can be described as monetizing surplus, stabilizing demand, raising local prices, or extending fossil generation depending on place and time.

Mobility distributes bargaining power unevenly

Capital and machines may move faster than workers, towns, and infrastructure. A borderless reward can therefore bargain with places that cannot exit at the same speed. Measuring decentralization requires more than the restored global total. We must ask who owns the moving capacity and who remains with the consequences after it leaves.
