Posts Tagged ‘Grin hard fork

The Grin project has already successfully hard forked once already earlier this year with a change in the C29 PoW algorithm from Cuckaroo29 to Cuckarood29 and now a second hard fork has been planned. Grin’s Hard Fork 2 is planned for block 524160 that should be reached sometime in January next year (around the middle of the month) with the testnet expected to fork a month earlier. Compatible versions of grin node, grin-wallet, and grin-miner will be versioned 3.0.0 or greater with the first releases of these are scheduled for December.

Grin remains true to its commitment to tweak CuckARoo as part of every network upgrade it does in order to discourage manufacturers from building specialized ASIC mining hardware for it, ASICs on the other hand are encouraged and being developed for the other algorithm C31 that Grin uses. As such, the currently used algorithm Cuckarood29 will be deprecated for a new algorithm called Cuckaroom. This means that if you want to be able to continue mining Grin with the C29 algorithm after mid-January next year after the fork happens you would need to update your miner software to support the new algorithm. The first beta binaries of the software should be available in the next couple of days along with details about the new algorithm, so miner software developers will have enough time to integrate the required changes for the new algorithm by the time the hard fork executes.

Today is planned the first hardfork for the GRIN crypto currency and more specifically its Cuckaroo29 (C29) algorithm to the new Cuckarood29, the C31 algorithm remains unaffected by this hardfork. Grin is expected to hard fork at Block 262,080 which is estimated to happen at some point today (July 17th, 2019). All you have to do to be ready to continue mining GRIN after the hardfork is to update your miner to the latest version, most of the software supports autodetection of the algorithm switch and thus should continue working jst fine after the fork happens.

The miners that have already released updates to support the new Cuckarood29 algorithm to be sued by Grin after the hard fork include: GMiner 1.51, NBMiner 24.1, lolMiner 0.8.5, nanominer 1.5.1 for AMD and or Nvidia GPUs on Windows and Linux operating systems. You can of course also use the official grin-miner 2.0.0 as well, although it is not available for Windows operating systems (only Linux and Mac OS X), unlike all of the other alternatives mentioned.
