Under Dorsey's leadership, Block made a big jump into bitcoin, including a years-long effort to design and build mining rigs.
Block's open bitcoin mining system is called Proto. Ahuja said on the earnings call that the company expects the initiative to start benefitting growth in the second half of 2025.
Dorsey has long said Block's goal is to open bitcoin mining up to the masses.
"We do think the market is large, and we do think we're poised to take a significant percentage of it," Dorsey said.
