Grin is a 3rd generation cryptocurrency focused on privacy, scalability, and fungibility. This coin is built by implementing the MimbleWimble protocol, which was proposed by Tom Elvis Jedusor (fictional name) in 2016.
With MimbleWimble protocol, Grin is able to verify transactions without revealing the values being transferred. This coin has no addresses or identifiable information in a transaction. Grin is private by default. Using MimbleWimble protocol, Grin is also able to remove old transactions on the blockchain, which is the approach they take to tackle the issue of scalability.
If you want to mine GRIN, there are few things you need to know. You can mine GRIN using GPUs or ASICs. This coin uses a concept called Cuckoo Cycle. Cuckoo Cycle is a combination of two algorithms; namely CuckARoo and CuckAToo. CuckARoo is designed for GPU mining and CuckAToo for ASICs.
The amount of memory required by these 2 algorithms is vastly different. For CuckARoo (CuckARoo29), you need at least 6 GB of video memory and for CuckAToo (CuckAToo31), you need 11 GB of memory.
Roughly 80% of GRIN blocks are mined using CuckARoo29 and 20% using CuckAToo31. CuckARoo percentage will gradually decline and eventually, all blocks will be mined with CuckAToo31+, the ASIC friendly variant. The next phase CuckAToo32 will result in 55% of blocks being mined using CuckAToo31+. In the final phase CuckAToo33, all blocks will be mined using CuckAToo31+.
As of now, you have 3 algorithms confirming GRIN’s blockchain. CuckARoo29, CuckAToo31, and CuckAToo32. If you have a GPU that has 11 GB of memory, you can mine all 3 algorithms. As a GRIN miner, you should select the algorithm that is most profitable to you.

If your graphics card is not listed here, you can calculate mining profitability manually. All you need to know is the power consumption of your graphics card, the hash rate for each algorithm, the electricity cost where you live, and the pool fee.
Power Consumption – You need to know the power consumption of your mining rig when mining GRIN. You can learn how to check your rig’s power consumption here.
Hash Rate – You can find the hash rate of your GPU by downloading mining software and mining GRIN. Alternatively, you can search on Google for mining benchmarks for your GPU.
Electricity Fee – The electricity cost in the area you live for every kWh consumed. Find this by inspecting your electricity bill.
Pool Fee – This is the fee charged by the pool you mine at.
Once you know all this information, you can easily input these values to a mining calculator like WhatToMine and check the profitability.
Mining GRIN With ASICs
There is a handful of ASICs available for GRIN mining. Here are the best ones:
This is a PCIe card manufactured by Innosilicon. It is capable of generating a hash rate of 21.5 GPS when mining CuckAToo31 and a hash rate of 4.5 GPS when mining CuckAToo32 while consuming just 140W.
This card weighs just 1.2 KG. You can install G32 – Mini just like a GPU card. G32 – Mini is self-contained with software, WiFi, and an Ethernet. You can power this card with your standard computer’s PSU.
G32 – 500 is capable of generating a hash rate of 100 GPS for CuckAToo31 and a hash rate of 20 GPS for CuckAToo32 while consuming 520W. This ASIC is slightly heavy weighing nearly 5 KG. If you do not already have a 110V/220V compatible PSU, you may have to buy one. If you want to own this ASIC, you have to preorder one from their official website and wait for the next shipping batch. They also ship with compatible PSUs.
Weighing just near 12 KG, G32 – 1800 model can generate a hash rate of 328 GPS while mining CuckAToo31 and a hash rate of 66 GPS when mining CuckAToo32. In the normal mode, this ASIC consumes 1800W of power. In terms of efficiency, this puts G32 – 1800 at 5.5W/H for CuckAToo31 and 27W/H for CuckAToo32. You can preorder this ASIC here.

How to Earn GRIN Without Mining
Mining GRIN is not for everyone. As you have noticed, mining GRIN requires somewhat high-end graphics cards or an ASIC. These are expensive hardware. If you have a low budget but still want to mine GRIN, there is a way around it. You can buy hash power from a service like Nicehash or MiningRigRentals and allocate that power to mine GRIN. The best thing about these services is that you can mine GRIN with a very little amount of money. If you do not like the slow process of mining GRIN, you can always buy some GRIN from an exchange like KuCoin.
When determining the best hardware for mining GRIN, you must consider the hash rate of your hardware, power consumption, electricity cost in the area you live, the total cost of the mining rig, and the estimated profit. Before you make an investment decision, always remember to use a mining calculator to estimate the profit.
