Is that a Virus? No!

Like all miners, JCE gets detected as a virus by most Antiviruses, including Windows Defender. But it’s not. Read more about Privacy and Security below.

Is it just yet-another fork of a common miner? No!

You’re not losing your time testing a made-up rip of a common miner, JCE is brand new, using 100% new code.

Are the new Monero-V, Cryptolight-V7 and Cryptonight-Heavy forks supported? Yes!

The --variation parameter let you choose the fork. More details below.


In short, JCE is:

Crazy fast on non-AES 64-bits, usually 35-40% faster than other miners
Still faster on non-AES 32-bits, usually beating even the other miners 64-bits versions
And still faster on non-AES 32-bits Cryptonight-Heavy, with usually +50% speed.
Barely faster than the other best on AES 64-bits, beating them by ~1%, +2.8% on V7 fork
Also a lot faster on AES 32-bits, but it’s a rare case (mostly seen on Intel Atom tablets)

Here’s a benchmark against three other common miners.
The test is fair: run on the exact same Win10 Pro computer, all Huge Pages enabled, no background task, best configuration.

XMRStak means: the released Unified binary from github (not recompiled myself)
XMRig means: the respective best released binary gcc (32-bits) and msvc (64-bits) from github (not recompiled myself)
Claymore means: best Claymore CPU (3.4 for 32-bits, 3.9 for 64-bits)
When not supported, score is zero, if not tested yet, score is ?

Basic topics

Q. Is it free (as in beer, as in freedom)?
No and no. It has fees, and is not open source. But the program itself is free to distribute.

Q. How much cost the fees?
Current fees are:

3.0% when using at least one mining thread with non-AES architecture, or 32-bits
1.5% when using only 64-bits AES architecture

The fees are twice higher in non-AES mode and/or 32-bits because JCE offers a huge performance gain here.

Q. Can I avoid fees?
Not really. I plan to offer a paying per-licence-no-fee (pay-once-for-all) version, but it’s a lot more complicated to set up than a fee-based miner.
Also, JCE never takes any fee during the first minute, so if you run it, and kill it after one minute, and repeat again and again, then you’ll never pay any fee, but JCE takes a few seconds to start, and your Pool probably won’t let your reconnect continuously.

Q. Will it work on my computer?
Minimum is Windows 7 32-bits, with a SSE2 capable CPU. 64-bits is faster, prefer it.
For best performance, Huge Pages must be enabled, JCE will try to auto-configure them, but it may work or not depending on your Windows version and security configuration.

Q. What currency can I mine? On which pools?
You can mine any coin on any pool.
If your coin is listed, all is automatic.

Run the miner with --coins parameter to get the up-to-date list. Current list is:

Monero (XMR)
Monero-V (XMV)
Electroneum (ETN)
Karbowanec (KRB)
Bytecoin (BCN)
Sumokoin (SUMO)
Bitcoal (COAL)
Bitcedi (BXC)
Dinastycoin (DCY)
Leviarcoin (XLC)
Fonero (FNO)
Turtlecoin (TRTL)
Graft (GRFT)
Dero (DERO)
Stellite (XTL)
UltraNote (XUN)
Intense (INTS)
Crepcoin (CREP)
Pluracoin (PLURA)
Haven (XHV)
FreelaBit (FBF)
BlueberriesCoin (BBC)
B2BCoin (B2B)
Bitsum (BSM)
Masari (MSR)
SuperiorCoin (SUP)
EDollar (EDL)
Interplanetary Broadcast (IPBC)
Masari (MSR)
Alloy (XAO)
BitcoiNote (BTCN)
Elya (ELYA)
Iridium (IRD)
Italo (ITA)
Lines (LNS)
Niobio (NBR)
Ombre (OMB)
Solace (SOL)
Triton (TRIT)
Truckcoin (TRKC)
Qwertycoin (QWC)
Nicehash Cryptonight v7
Minergate Cryptonight
MiningPoolHub Cryptonight
MiningRigRentals Cryptonight v7
Suprnova Cryptonight

Otherwise, use the --any parameter, plus the --variation N parameter, with N the fork number, see list below. The fork detection is automatic on known coins, but manual on unknown coins. The coin list is periodically updated.

Q. Is Nicehash supported?
Yes, see list above. The Nicehash-specific Nonce is then automatically enabled.

Q. Is SSL supported?
Yes, with parameter --ssl

Q. I get only bad shares, what happens?
Your coin has probably forked. Add --variation N parameter, with N as listed below, until you find the one that works.

Q. Is there a HTTP server to monitor the miner?
No, modern pools provide all you need to monitor your miners (average hashrate, worker-id…). Monitoring is now a pool’s job.

Advanced topics

Q. Are there requirements or dependencies?
No. JCE is just a big standalone .exe

Q. Is there a Linux version?
Not yet.

Q. Is there a GPU version?
Not yet.

Q. Is there a 32-bits version?
Yes, both 32 and 64 are always in the same release.

Q. How many threads can I setup?
Maximum is 64 threads on 64 CPUs.

Q. Do I get a discount on fees if I use SSL?
I’m not Claymore.

Q. What is that value logged when I find a share?
The amount of hashes your pool will credit you. This is not the amount of crypto-coins.

Q. How is developed JCE?
The network and stratum handling is C++14, and the mining algos are assembly (to be precise, GNU Extended Assembly). Hence the speed increase.

Q. Can I plug it to a stratum proxy?
No, it must mine on a real pool on Internet.

Q. Is it really new? It looks familiar to me…
Yes it is. But it reuses, on purpose, some de-facto conventions from other common miners, like a XMRStak-style cpu configuration, and the colors of Claymore (green=share, red=error, blue=hashrate, yellow=status).

Q. How is the hashrate calculated?
That’s the average speed of the last 512 hashes (not shares found, computed hashes), rounded at 0.01. And it’s fair, the displayed number has no tweak, and includes the fees. The total is first summed from exact per-thread values, then rounded (said differently, it’s a rounded sum, not sum of rounded).

Q. Can I get a long-time speed average?
Better look at your pool’s reports, but JCE also gives the average effective net hashrate when pressing R. It’s usually slightly lower than the physical hashrate because of outdated shares and fees.

Q. Can I do multi-pool auto-switch in case of failure? Or periodically?
Not directly, but the -q and/or the --autoclose parameters, with the help of a simple .bat, can do the job. The .zip comes with an example, open and edit it to match your needs.

Q. Can I mix architectures when mining (i.e. thread 1 uses core2, thread 2 uses pentium4)?
It sounds strange, but yes. However, that’s mostly useful for tests.

Q. I used “use_cache”:false and it still has a strong negative impact on other threads
The no-cache mode means the cache is instantly invalidated once used, not always entirely bypassed, depending on your hardware. And a mining thread always has an impact on TLB. So don’t try to use extra mining threads playing with the no-cache mode, rather use the dual-thread mining, which is made for that precise purpose.

Q. What a great job! Can I make a donation?
Thanks bro. You can, with the --donate parameter which raise the fees to 80%, or by sending coins to the donation wallet (the one in the start.bat file included).

Cryptonight Forks

All current forks are supported:

N=0 Automatic
N=1 Original Cryptonight
N=2 Original Cryptolight (for AEON)
N=3 Cryptonight V7 fork of April-2018
N=4 Cryptolight V7 fork of April-2018
N=5 Cryptonight-Heavy
N=6 Cryptolight-IPBC

The current Automatic mode behaves the old way on alt-coins:

Monero, Monero-V and Stellite are now Cryptonight V7,
Sumokoin is now Cryptonight-Heavy,
Aeon is still Cryptolight
TurtleCoin is now Cryptolight V7
Interplanetary Broadcast has is own Cryptolight-IPBC
Everything else is still assumed Cryptonight
