Dear Customers,

We are extremely happy to be shipping the first batch of the SP31.

To build the SP31, we were able to improve the performance of our 2nd generation ASIC (“RockerBox”). We’ll continue to push the envelope and improve the ASIC further in next batches.

Testing of the new units resulted in the following modifications to the original specifications:

•   The SP20 will reach the expected 1.7TH/s +- 5%. Current power draw measurements show usage of 1.2kW with 90% efficiency PSU
•    The hash rate of the SP31 will be 4.9TH/s +- 5%. Power consumption will remain the same 3kW at the wall as in the previous SP30.
•   The current results are expected to affect the specifications of the SP35 as well with units currently under test showing 5.5TH/s +- 5% using 3.65kW at the wall.

Ever since the launch of our first product in March we have been pushing the boundaries of power efficiency and quality of design, to make sure our customers have access to the best technology available. We are proud to have continued to do so with the SP31 and SP35.

Our commitment to our customers is as it has always been: to preserve the USD per GH/s ratio that was promised to them. We will compensate all customers for the difference in hash rate based on preserving the USD per GH/s ratio of the original deal.

As with previous batches, delivery dates will not be affected by these changes

We remain at your disposal for any concerns or questions and we look forward to continue serving you in the future.

Best Regards,

Guy
