There are a large number of Proof of Work cryptocurrencies with each powered by a different hashing algorithm. The most adopted algorithms are SHA-256, Scrypt, Ethash, Equihash, CryptoNight, NeoScrypt and Keccak. Among these some of the algorithms are ASIC friendly and some of them are designed with CPU and GPU miners in mind.
Most cryptocurrencies either implement algorithm that supports ASIC mining or they aim to be ASIC resistant coin. On the other hand there are few cryptocurrencies that uses several different hashing algorithms in order to give fair opportunity to both ASIC and GPU miners. For example: Verge (XVG) which uses Scrypt, X17, Lyra2rev2, Myr-Groestl and Blake2s. Another example is Shield (XSH) coin which is also a multi algorithm coin. Here we are not going to specifically discuss about Shield or Verge coin but one of the algorithm that they both use and that is X17 hashing algorithm. We’ll see the list of coins that uses X17 algorithm and the miners that you can use to mine this algorithm.
X17 Proof of Work algorithm
In order to prevent the use of ASIC miners Dash created an algorithm that is much complicated than SHA-256. They chained 11 different hashing algorithm into one and hence the name X11. However unfortunately both ASIC and FPGA cracked X11 and that is what gave rise to X13, X14 and X15. Later on ASIC became available for all these algorithms and the only one that is currently left is X17.
X17 is a combination of 17 different hashing algorithms and the 17 hashes that make up X17 are:
Blake, BMW, Groestl, JH, Keccak, Skein, Luffa, Cubehash, Shavite, Simd, Echo, Hamsi, Fugue, Shabal, Whirlpool, Loselose and Djb2.
X17 is an ASIC resistant mining algorithm. It can be cracked but currently there are no ASIC miners available for X17 yet which makes both CPU and GPU mining possible. Following are the CPU and GPU miners that you can utilize to mine X17 algorithm.
X17 mining software
A lots of miners are capable of mining X17 coins but we’ll not be sharing them all here. Instead we’ll only share miners that are largely chosen by the community and produces best results.
First of all x17 isn’t very CPU efficient and due to GPU power CPU mining is not recommended. Anyways if you are looking for a CPU miner for X17 then you can give the following miner a try.
Remember; NVIDIA is much better than AMD on mining X17 algorithm. Mining X17 coins directly using AMD won’t yield profitable results. So our suggestion would be to mine other coins and exchange them or you can mine Lyra2rev2 or you can dual mine XVG / XSH with Eth and Blake 2s. Anyways if you are interested in mining X17 using your AMD GPUs you can use the following miner.

Wide range of miners are available for NVIDIA but the best X17 Miner is CCminer Alexis version.
It is an open source miner which gives around 10% better performance than regular CCminer. In addition to this there are some closed source miners which also performs better. You can try both T-Rex NVIDIA miner and Enemy Miner.
Alright! Now before you mine you may wish to know the performance. Following are the X17 hashrates that you can expect from your hardware.
GTX 1080 TI: 15 Mh/s GTX 1070 TI: 13 MH/s GTX 1070: 11 Mh/s 1060 6 GB: 7 Mh/s 1060 3 GB: 5 Mh/s RX 470/570/580: 5.9 to 6.9Mh/s RX Vega cards: 11 to 12 MH/s
Note: X17 is core based and not memory so to achieve best performance increase core clock. Also compared to Lyra2v2 and Blake 2s; X17 runs cooler. Okay, now let’s see the list of coins that you can mine using X17.
All X17 coins
The first cryptocurrency to implement X17 is Peoples cryptocurrency (PPL) but this coin is no longer active. Currently there are only 4 coins that uses X17 and out of all only one coin uses X17 alone. Rest all three are multi algorithm coins. The four currencies that uses X17 are:
- Verge – XVG
- Shield – XSH
- MktCoin – MLM
- Volvox – VVX
Verge is a decentralized, open source, anonymous and secure cryptocurrency that is designed for everyday use. It uses multiple anonymity-centric networks such as TOR and I2P. Some of the other features includes: Atomic swaps and Multi algorithm mining.
