[Part 2 of 3]
Host: [unclear] the current average predictive performance of Method C is nearly thirty percent [30%]. Can you improve on that, Francesco?
Gardin: Yeah, I mean we have been before releasing this announcement and we had this data since like November last year. But before releasing the announcement we've been testing and testing again this data from all different perspectives with different devices, GPUs, ASICs, and when we got the confidence, then we released the announcement.
Host: So you also say it results in a reduction of SHA256 computations. Does this make it cheaper for the end user at the end of the day?
Gardin: Yes. Because basically with the same hardware you save 30% of computations which would be, according to the Oracle, not essential. So basically you focus only on the computation which stand a chance to be successful.
Host: OK, but it may result in slightly higher energy usage, though, but that's, I suppose, offset by the more effective nature of the Method C.
Gardin: Sure, you have to look at each input, which has a cost, but you save 30%, so the whole point is that by looking at them 100% of the time, and not processing them 30% of the time, and the final balance is a positive balance.
Host: What's the next steps then for Method C, Francesco?
Gardin: It's to combine with the second patent application. And as we are already doing, implement it on our prototype chip, which we are working on, so that we can implement Method C also for CPUs, and also as a hard-wired ASIC element of a bitcoin mining ASIC.
Host: So Francesco, that prototype chip was also covered in the business update. Can you tell us a little bit more about that, please?
Gardin: Yeah. In order to have more credibility with our potential partners, we not only have to show them the, describe the architecture of the chip, but we want also to show them that the actual chip, this architecture, works. So in order to come up with a prototype chip of 5 nanometers, the investment is in the region of two million (ÂĢ2m). If we choose a bigger scale, like 55 nanometers (55nm), 22 nanometers (22nm), 130 nanometers (130nm), then the investment is one tenth of that. And we can sit at the table negotiation with potential partners say here is the chip, yes it's not 5 nanometers (5nm), 3 nanometers (3nm), but it's just a matter of investment to scale it down, but the chip works. So that's very important for us.
