Lokotech AS, a wholly owned subsidiary of Harmonychain AS, has today made
important progress on verification of the MPW chiplet.

The prototype is now hashing live on the main network from Norway. The hashing
is verified by an independent third party.

It is an important milestone to go from testing in a simulated environment to
verifying that the design also works as expected when receiving real computation
jobs from the Litecoin and Dogecoin networks. The technology is now considered
Technology Readiness Level 5 (ISO 16290:2013).

The number of unique customers who have indicated their interest has exceeded
2,200, and this is before customer demonstrations have taken place. We expect
the number to increase as a result of having reached this milestone in the
period leading up to the opening of the pre-sale. The size of the customers
varies from a few to several thousand units.
