JCE Cryptonote CPU Miner Welcome to the Fastest Cryptonote CPU Miner ever! You can download it from the Mega page here: MEGA 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-V7, Cryptolight-V7, Cryptonight-Heavy, IPBC, Alloy, MKT and XTL forks supported? Yes! The --variation parameter let you choose the fork. More details below. Speed In short, JCE is: Crazy fast on non-AES 64-bits, usually 35-40% faster than other miners Compared to other 32-bits miners, still faster on non-AES 32-bits, sometimes 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, +4% on Cryptonight-Heavy 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 ?

The most common is Monero. Get a wallet, that’s a ~95 character long identifier. If you don’t have one yet, you can create it Choose a pool to mine on, and its port. For example Pool pool minexmr com and port 4444 Edit the start.bat that’s shipped in the .zip Change the example POOL by yours Change the example PORT by yours Change the example WALLET by yours You can leave the default password x (Optional) If your coin is exotic, maybe you also need to change FORK=0 to another number. See the list in the start bat Run start bat 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 Vista 32-bits, or Linux, with a SSE2 capable CPU. 64-bits is faster, prefer it. For best performance, Large 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) Alloy (XAO) BBSCoin (BBS) BitcoiNote (BTCN) Elya (ELYA) Iridium (IRD) Italo (ITA) Lines (LNS) Niobio (NBR) Ombre (OMB) Solace (SOL) Triton (TRIT) Truckcoin (TRKC) Qwertycoin (QWC) Loki (LOK) Ravencoin(RVN) Gadcoin (GAD) MarketCash (MKT) ArtoCash (RTO) Nicehash Cryptonight v7 Minergate Cryptonight v7 MiningPoolHub Cryptonight v7 MiningRigRentals Cryptonight v7 Suprnova Cryptonight v7 Otherwise, if your coin is not listed, or your wallet not recognized, 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. What if my wallet is not recognized, or as a different coin? Some coins use a wallet syntax so close that they’re hard to differenciate, like Lines and Loki. If JCE fails to detect the coin, force it with --any --variation N (with N as listed below) and let the miner run. It will still display the wrong coin but mine the good one. And of course proof-check pool side that you correctly get the shares. Q. Is there a HTTP server to monitor the miner? Modern pools provide all you need to monitor your miners (average hashrate, worker-id…). Monitoring is now a pool’s job. Still, a minimal HTTP Json server is available with parameter --mport P (P the port number) to ease integration of JCE into mining tools, but not intended for human reading. Forager was the first tool to integrate JCE, take a look! For more compatibility, with extra parameter --stakjson, the JSON will be in XMR-Stak format. Advanced topics Q. Are there requirements or dependencies? No. JCE is just a big standalone executable. Q. Is there a Linux version? Yes, starting from version 0.29 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, for both Linux and Windows. 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. What if the Architecture codename is wrong (e.g. my CoffeLake is detected as Core2)? It may be because of an option in your BIOS Max CPUID or the microcode is not up-to-date. However the codename displayed is mostly cosmetical and JCE will still choose the good assembly based on your CPU instruction set. If a normally available instruction set is missing (e.g. your Westmere has no AES) again, that’s to be unlocked in your BIOS. 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. Can I mix coins when mining (i.e. thread 1 mines XMR, thread 2 mines ETN)? No. Q. Can I mix simple-hash and multi-hash? Yes, and it’s a very common case when mining TurtleCoin or IPBC. Q. What is “use_cache”:false useful for? The no-cache mode means the cache is mostly bypassed, depending on your hardware. When using a lot of cache but few cores (typically when mining Cryptonight-Heavy) assigning unused physical cores to no-cache mining can give you a few extra h/s for free. However mixing cache and no-cache of logical CPUs of the same physical core causes terrible performance. 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).
