Zcash mining giant Fortitude Mining plans Nasdaq listing via reverse merger

Fortitude Mining, a subsidiary of Digital Currency Group (DCG), is pursuing a Nasdaq listing through a reverse merger with HeartSciences. The company, which mined approximately 28% of all ZEC in the first half of 2026, has appointed former Hut 8 CEO Jaime Leverton to lead the transition. The combined entity will operate under the ticker 'TUDE'. Meanwhile, the Zcash network is preparing for the Nu7 upgrade on November 5, which will reduce block times from 75 seconds to 25 seconds.
