The DERO project is another crypto that last year had announced their plans to switch the mining algorithm to a RandomX variant and they are finally doing it. Tomorrow, March 7th at block 4550555, marks the time that DERO will be switching to the new CPU mining POW called AstroBWT. So if you are into CPU mining you might want to give it a try after the fork and see what DERO will do with the new algorithm. The project itself has been available for quite some time and has been in constant development, relying on the CryptoNight algorithm prior the upcoming fork to their new AstroBWT algorithm
AstroBWT is a CPU mining only algorithm and apart from the official miner for the algorithm, there is also the latest XMRig 5.8.x major release that added support for the algorithm a few days ago and the minor releases since then have improved it by fixing issues and significantly increasing mining performance. So make sure you try XMRig on your CPU mining hardware it time for the fork in order to be ready when the hardfork happens, that is if you do plan to try mining DERO with the new AstroBWT algorithm.
