Rupee is based on scrypt mining algorithm. Rupee can be mined like any other scrypt based coin (litecoin, and others). The third-party pool which Rupee team promotes is https://rup.miningfield.com/
Rupee can be mined with GPU, ASICS, but for new people GPU has much less mining power compared to ASIC. Each unit has a hashing power which means how much calculations can it perform in one second to mine the next block. GPUs have 20 times less mining power compared to ASIC. The price of ASICs are close to 3000 USD if bought from Amazon or Ebay. GPU cost close to 400 USD.
Mining is difficult for new people, and with less hashing power
Role of Multipools
Multipools are mining pools where people can combine mining power, and this way they have a better chance of mining the next block. But, multipools are a trouble for new and small coins. As new coins don’t have much dedicated power, so multipools basically mine all blocks, and leave as the difficulty goes up. The dedicated miners mine the next block, as soon as the difficulty comes down, multipools comes back. The fact that multipools have huge hashing power compared to dedicated miners ( especially in new coins ), Multipools mine all next blocks, and sell those in market, and as difficulty goes up leaves. As multipools leaves the next block takes some time to mine ( typical 4 to 5 hours ), in some cases we have seen 9 hours .
The same issue is true with every other coin. Bitcoin Cash, and Bitcoin Gold also experience the same issue
Rupee difficulty retarget was changed to dark gravity wave algorithm in November to overcome this issue, and adjust the difficulty every other block. More information about dark gravity wave algorithm is given in the end.
At the moment there are two multipools mining us ( https://www.mining-dutch.nl/ and http://zpool.ca/ ) . These pools come and go. Once they come, they mine effectively all blocks, as the difficulty goes up these pools leave, leaving the dedicated miners to solve the next block.
How to mitigate Multipools
Rupee team has decided to keep mining decentralized, the only way to do it is always to have a memory intensive mining algorithm. Equihash, and Lyra2Rev2 are the two memory intensive algorithms. Rupee code will be updated in future to Equihash to protect us against multipools, and allow normal people to mine Rupee with readily available mining equipment (GPUs ).
Blocks not coming for few hours/Slow transactions
This is due to Multipools coming and leaving, which causes the slow blocks. We are using the best difficulty readjustment algorithm ( Dark Gravity Wave algorithm ), to decrease the mining difficulty after every other block. This is totally normal for all new coins. Even Bitcoin Cash experienced the same issue. We will be changing mining Algorithm to Equihash to overcome multipools, and make mining decentralized again.
If your transaction is stuck, don’t be alarmed or panic. It will go through when the next blocks are mined.
Expected time line of code change
Team is working on a private test net to test the code changes, but at the moment, Rupee is coming on few new exchanges, and if we implemented the code it might cause some issue. So, we are checking when to have the code changes done. We will announce it after consulation with exchanges, and mining pools.
