according to The Block, Thumzup (NASDAQ: TZUP) will acquire Dogehash Technologies in an all-stock deal. This acquisition appears to be one of Thumzup's moves towards a new direction in cryptocurrency mining.

Dogehash is an industrial-scale blockchain mining company focused on the Scrypt algorithm used by Dogecoin and Litecoin. According to the terms of the agreement, Dogehash's shareholders will exchange all their shares for 30.7 million shares of Thumzup. The company will be renamed "Dogehash Technologies Holdings, Inc." and will trade on NASDAQ under the new ticker symbol "XDOG." The transaction is expected to be completed by the end of this year.
