grin cuckarooz29 hardforkOn July 16, 2020, the third GRIN cryptocurrency hard fork is planned for block 786240. In addition to some changes in the network operation mechanism, the mining algorithm from the current Cuckaroom29 to Cuckarooz29 will be changed in the new version 4. For other GRIN cryptocurrency POW algorithms - Cuckatoo31 and Cuckatoo32, there will be no changes in the current hard fork. To switch to the new version of the GRIN cryptocurrency software, you can now download the wallet version 4.0 on the official Grin.mw website. But the miners will have to wait a little longer, because miners Bminer, Gminer, Lolminer, popular for mining, have not yet announced support for the new Cuckarooz29 algorithm.
