Butterfly Labs ASIC Pre-Orders
Butterfly Labs opens pre-orders for the first ASIC miners, initiating the industrialization of mining and years of controversy.
On June 23, 2012, hardware manufacturer Butterfly Labs (BFL) officially opened pre-orders for their 'BitForce SC' product line, claiming to have developed the world's first Application-Specific Integrated Circuit (ASIC) for Bitcoin mining. This announcement signaled the end of the GPU mining era. BFL promised devices that were exponentially faster and more energy-efficient than any graphics card on the market—for example, the 'Jalapeno' unit promised 4.5 GH/s for just $149, a hash rate that would have cost thousands of dollars to achieve with GPUs.
The announcement triggered a massive influx of capital into mining hardware, sparking an 'arms race' to secure the network. However, this event is equally famous for the controversy that ensued. BFL accepted millions of dollars in pre-orders but failed to ship products for over a year. By the time customers received their miners in late 2013, the network difficulty had skyrocketed, rendering the machines largely useless.
Despite the operational failure and eventual FTC shutdown of Butterfly Labs, the announcement itself was a pivotal historical moment. It forced the community to confront the reality of mining centralization. The shift to ASICs meant that mining would no longer be a hobbyist activity possible on a home computer, but an industrial operation requiring specialized datacenters. This transition massively increased the network's security (hash rate) while simultaneously concentrating power in the hands of hardware manufacturers.
