According to TechFlow, The Block reported that Jack Dorsey's company Block and Core Scientific have reached an agreement. Block will provide Core Scientific with a new 3nm mining ASIC. The ASIC was built by Block's Proto team and has a hash rate of approximately 15 EH/s.
Block said the main purpose of its Proto Mining program is to increase the decentralization, transparency and resilience of the Bitcoin network by working with the mining community to build mining chips, systems and software solutions in an open and transparent manner, including the Mining Development Kit (MDK) currently in beta.
