Dr Wright first claimed to have operated a large number of computers (67) at his home in Australia at the start of the Bitcoin system in a blog on 6 April 2019 {L14/420/2} and in a CoinGeek interview on 6 June 2019 {O4/12/13} (this time with 69 machines). These claims were expanded upon in his evidence-in-chief in the Kleiman proceedings {L17/327/105}-{L17/327/108}. He suggested there that he was running 69 machines in four racks spread over his homes in Lisarow and Bagnoo at a monthly electricity cost of AU$11,000.

At Wright1 [116] {E/1/22} he appeared to suggest that he was in fact running 69 racks at those residences, but explained in cross-examination by COPA that he meant 69 computers in racks. At Wright1 [117] {E/1/22} he nevertheless went on to say that the “considerable electricity consumption associated with Bitcoin mining represented a significant expense for me, amounting to thousands of Australian dollars” and confirmed in cross-examination that he stood by the figures stated in Kleiman.

The Developers submitted there were two main problems with this evidence.
