CryptoNight-Heavy review[edit]

Cryptonight heavy is a version of CryptoNight hashing algorithm. It is implemented in such cryptocurrencies as Ryo Currency (RYO), Sumokoin (SUMO) and Loki (LOKI). CryptoNight Heavy is ASIC-resistant and not adopted widely enough to gather attention of ASIC developers. Cryptocurrencies choose CryptoNight Heavy to provide themselves with a robust and long-term protection against being a target for ASIC development. As a member of CryptoNight-based algorithms, CryptoNight Heavy shares most of the features that made CryptoNight popular. With CryptoNight Heavy implementation, developers provide users with:

  • Untraceable transactions
  • Blockchain analysis-resistant network
  • Double spending protection
  • Ring signatures

Mentioned features make CryptoNight Heavy-based networks as secure and private as famous examples of CryptoNight-based cryptocurrencies like Monero and Bytecoin.

Advantages[edit]

  • CryptoNight Heavy is yet to become a target for ASIC developers and can provide miners that use GPU with steady cryptocurrency gains
  • CryptoNight Heavy implements adaptive network limits, which means that block reward, fees and other specifications of blockchain are adjustable for the whole lifetime of the network
  • CryptoNight Heavy is well suited for miners with advanced mining gear

Key differences from CryptoNight[edit]

The main difference between CryptoNight Heavy and CryptoNight is that it provides an increase in scratchpad size from 2 MB to 4 MB. CryptoNote Heavy also changes the way implodes and explodes are handled. These changes differentiate it from the largest target for ASIC miners which is CryptoNight V7 of Monero.

Mining[edit]

CryptoNight Heavy mining is available for the central processing units, graphic processing units and cloud mining solutions. However, most CPUs won’t be able to mine CryptoNight Heavy-based coins profitably. Cloud mining is not really profitable most of the time and the service you may choose for mining can turn out to be a scam. So, the best option for mining of CryptoNight Heavy-based coins is to use highly efficient GPU. Not all mining software developed for CryptoNight algorithm family cryptocurrencies supports CryptoNight Heavy. Examples of CryptoNight Heavy-compatible mining software are Cast XMR and SRBMiner CryptoNight AMD GPU Miner. You may have mentioned that miners specify their compatibility with a developer of the GPU. Both of mentioned software works only with AMD GPUs. AMD graphic processors are also widely considered to be the best option for the mining of CryptoNight coins by the cryptocurrency community. Mining of coins based on CryptoNight Heavy with NVidia hardware is less efficient for almost all CryptoNight coins. If you want to try CPU mining out, you may consider using JCE Cryptonote CPU Miner or XMRig. Both examples of software are only working with CPUs, however, there are solutions that are managing the CryptoNight mining with both GPU and CPU. Various mining solutions offer different users conditions such as developers fee, opportunity to work with source code and so on, so better check these in advance. As CryptoNight Heavy is very resource-hungry, hashing power of ordinary miner’s hardware can be insufficient to mine solo. The best option to choose whether to mine solo or to join a mining pool is to check the gear with various benchmarks and see if its powerful enough to mine profitably. Solo mining is great, but has its flaws as it does not provide miners with stable rewards and may be too difficult in terms of required hashing power for some cryptos. Mining pools, however, offer steady rewards but take some of the income to cover the fees.
