 4th AnniversaryFujicoin celebrated its 4th anniversary. Looking back on this one year, we were able to achieve various improvements. · Activation of SegWit: This opens the way to lightning network and atomic swap. · Enriching the wallet: electrum-FJC, Coinomi Android & i-OS, TREZOR. These have greatly improved the usability of Fujicoin. · Enriching official pool: We have launched 4 pools. · Enhanced communication: fujicoin slack, and reddit. · Anti 51% attack: Deployed in version v 0.16.1. These improvements were achieved through the support of community members. Please look forward to the strong growth of Fujicoin in the future.  But as far as I can tell. Fujicoin is just a direct clone of btc but using scrypt n. So What does it have to offer over any of the other hundreds of also copied clones in the same Manner? I see no hook to differentiate this coin from btc, but for it being later than btc protocol As a copy and scrypt n  It is the same as litecoin that fujicoin is a simple fork of bitcoin. litecoin just adopted scrypt for the algorithm. However, fujicoin has better points than litecoin. That's the coin issuing algorithm. Bitcoin has already issued 82% of coins. And bitcoin has the problem of only a few people have a very large proportion of it. In contrast, fujicoin currently only has 13% coins issued. The supply of coins exceeds 80% is around 2030. Supply of Fujicoin is determined based on the theory of Diffusion of Innovations (S-Curve). The adoption of this supply method is the greatest feature of Fujicoin and realizes fair allocation of coins. Still don't get it. Litcoin has speed increase. Fujicoin fair distribution is just fine...but it comes down to if it is identical to bitcoin and has fair distribution ..it is just another clone of bitcoin, using scrypt-N ..it is not enough. Litecoin had the advantage of being first and the transaction speed angle....getting fair distribution of a lot more fujicoin than ever was pumped out of the 21 million bitcoin..still seems too late to the party and not enough to differentuate fujicoin from other coins you need some new features IMHO, just saying it is fair..making more coins...making it scrypt-N and following along...hell, a mess of other coins do such......the dev needs to add more to this coin in features or will be lost in the crowd IMHO....if it was gonna happen it would have started in 2014 at your launch...again, not to be an ass, but not seeing it happening without further enhancements or hooks on this coin to attract the masses..then the fair distribution may come into play..but not till fujicoin has more depth...again IMHO. As far as lightning and the seg witness aspects...all those other clone coins of many scrypt flavors identical in all (but maybe the fair distribution) also just added the 16.1 features etc etc...again....treading water is nice...but coin needs more work, in my view. brad  You should speak after studying Fujicoin properly. I made a comparison table with Litecoin for you. Fujicoin's transaction is more than twice as fast as Litecoin. In addition, Fujicoin forked from Bitcoin in 2014, but how do you evaluate BCH forked in 2017? Point taken....however, with not a lot of progress since 2014...you still need more 'hooks' on this coin IMHO,(ask around I'm sure others on here will agree) I've no idea what, masternode>partial pos? etc etc even with the speed etc...the fact is LTC is struggling against BCH as a fork of BTC...just saying..you need something hopefully 'more innovative' then simply keeping up with BTC patches again, no idea what, if you have such and are keeping it to yourself fine, I have some ideas pm me.... but again, it likely, imho is just not enough to 'float the boat" in 2018 vs 2014 innovativeness for a coin not a slam, but anyway, send me a pm...I'll let you in on something I think you should exploit.... otherwise, I'll keep my views to myself now....but again 2014 innovations and just keeping up with BTC just, don't seem to me ...to be enough or this coin would have 'popped' with the others in 2014 onward as well anyway my 2 fujicoin's worth brad To be fair, this coin did pop in '17 and lasted through early '18 ... now its back to 4 sats where it was pre '17 bubble. Thats ok tho, nearly all coins are going back to near pre '17 bubble by beginning of '19... no worries. |

The reason why remittance of electrum-FJC-3.0.5 is unstable was found to some extent. Upgrading the electrum to 3.0.x makes it necessary to upgrade the version of the server, but there seems to be a factor that makes the connection with the electrum unstable on the server side. Also on the electrum side it seems that problems on the P2PKH relation are left behind due to the influence of the fix for native segwit corresponding to 3.0.x series. Based on these results, we will make the following policy regarding electrum-FJC. · Release electrum-FJC-2.9.5 which took measures against the vulnerability of JSONRPC interface. · Restore server to old version. (Electrum-FJC-3.0.5 can not be connected) · The release of electrum-FJC-3.0.x will be postponed until it can be determined that the original electrum and server have become stable.

I'm confused what state I'm at in the process. My Titan has been running flawlessly since 2014 getting app 350 Mh/s with the stock settings of 325 MHz and -.0366 V but has always run hot. I never saw any real benefit to running the GenTarkin firmware but after recently adding an L3+ to my home mining, I thought I try the GenTarkin firmware Energy Saver feature in an attempt to get some heat out of my environment. I started the Energy Saver and it immediately made some changes including turning off dies with temps over the 90 degree threshold (e.g.: Dies currently throttled due to DCDC over temp threshold) and reducing a few to 300 MHz
Based on a reading of the documentation, I was expecting nothing to happen immediately since it says:
When energy saver is turned on. Stage 1 of 3 begins: It will restart bfgminer, have an initial 1.5hr cooldown then the first voltage adjustments will be made. All enabled die voltages will be lowered a single “notch”.
I didn't experience a 1.5 hr cooldown before adjustments were made but experienced immediate adjustments.
Also, the Energy Saver immediately went into an "IDLE" state which I interpret as nothing happening based on Status – IDLE – when no tuning is in progress from the documentation
Is something taking place? If not, how do I leave the IDLE state and restart the Energy Saver process?
Thanks
Sorry for the confusion, The documentation on "energy saver" states this as well: "Is there anything I should do prior to enabling “Energy Saver”? To get the quickest and most reliable results: Please turn off dies which are very unstable or problematic. Please set dies listed in auto-byass state to “OFF” and clear the bypass list. Please ensure that NO dies are in a throttled state." So, those dies which were throttled at the onset of your "ENABLE ENERGY SAVER" .... probably caused some weird behaviour w/ the dies that were throttled. I would recommend ... doing as the documentation says. If ur running 90C on the DCDC temps .... thats quite a risk, you can adjust the maximum DCDC threshold up higher if you want to start energy saver reliably ... but I dont recommend it at your temps at all. |

Stock voltage should be fine. At this point there is not a lot to be gained banging on the Neptunes. Hash rates and such are gotten by using the APIs from BFGMiner.
C
Thanks again. Yeah, I realize they aren't really profitable. A friend brought them over and it's difficult to watch specialized hardware sit idle. I have some BFL's, Antminer S1's & S3's, over 80 Gridseeds and some KNC Neptunes. Have you ever made any instructional/educational videos regarding electronics? You must not pay for power =P |

Hi GenTarkin I loaded today your firmware and started the energy save mode but somehow the first step don't finish. I get the following message like three times in 5h:  After the last time the miner didnt load anymore the settings, just came this picture:  I shows me BFG Miner 5.0.0 and I recognized in some of your pictures on the webpage I visible 5.1.0. Is there a newer update available I might should try? Thanks for your help Looks to me like your Titan image is borked .... BFGMiner being version 5.0.0 tells me you probably loaded my firmware upgrade on KNC firmware older than 2.00 ... my firmware is only officially tested and working on that version or 2.02 |

"Under the most adverse scenario, the price of the cryptocurrency could fall to $2221" $2200, he said $2200?  Reached $4400 to fall to $2200, that's a big fall, I want to believe it falls to $3600, but no more back below $3000 Well when this bubble ultimately pops, we will land back at a stable floor of $700-1200 for a good year or 2 , just like the pattern observed in previous crypto bubbles =) |

Looking to sell 9 KNC titan miners. 8 are Second batch ( 5 cubes) and the other one is first batch (4 cubes). There is only 4 dead die For all the cubes. Shipping from Canada. Dm your offers. Please only serious buyer. Can send pictures if needed.
Arent these already obsolete in the mining business? Im still interested depending on the price? Kind regards emiL932 They are close to being obselete but not quite there yet =P ... They've been probably one of the most profitable ASIC's for the longest amount of time in crypto mining. |

Tarkin, something to be aware of: I think each supply is programmed slightly differently to take advantage of a master clock signal. The supplies beat at 180 degrees out of phase with each other, which is why you can't swap a top and bottom supply in a pair for a die. However I think each supply actually beats off an 8 phase clock. In other words:
First pair beats 0,180
Second pair beats 45,225
Third pair beats 90,270
Fourth pair beats 135,225
Result is the board runs like a friggin 8 phase power supply. No wonder the filter caps are small.
But it means each supply is programmed to be what it is based on it's position on the board. very clever.
C
Im pretty sure you are correct. From what Ericsson told me, each pair of DCDC's is configured as its own common current group, which I can see evidence of in certain registers of each DCDC. Also, it seems they use interleaving for each of the 4 groups, the interleaving w/ the combined common setting of automatic phase control in each group ... I think gives it the unique phases per board =) Does any of this help the 'magic' gen tarkin firmware from going in and doing some kinda diagnostic ..to get dead dies back in some manner (or say comes back with a list of recommended settings to attempt) long shot here...but I'm 'barely' following the conversation..so maybe all this work you are doing on this...that the above idea is 'implied' and I'm too far behind the curve on the tech speak to realize this as an aside you and lightfoot really need to get out more....find some new asics to toy with...contact bitmain or something ...god knows enough of the stuff could use some tweaks or how to fix ..that you guys know how to do..if given the proper specs and motivations I dont think theres much more tweaking that can be done to Titan, aside from switching speed to 200khz to shave another few watts off the meter. But, at this point in Titan's life cycle ... it may be a moot point to write all the code to implement the changes so its easy for end users =/ time will tell tho. I still got my Titan =) ... Ill be getting an L3+ in late september and Ill dig around in the firmware see if anything can stand to be optimized. |

This is interesting:
So I've been thinking about the power supplies and some of Tarkin's thoughts. He discovered that the supplies have different programming and I was wondering why. Why are the supplies programmed differently and what can you do with that?
Out came the scope to take a look at the phase varience on each supply. We know that two supplies should beat 180 degrees out of phase with each other, that's the master/slave relationship on each side. Provides smooth power for the chip with less capacitors required.
What I see now is that they had a master clock signal coming from one of the supplies, and the 4 pairs adjusted their phase to be 180 degrees from their pair as well as 45 degrees offset from each other pair.
In other words, the first set fired at 0 and 180. The second set fire at 45 and 225. The third set fire at 90 and 270, and the fourth fire at 135 and 315. That way the 12 volt rai sees an 8 phase power supply pulling from it, which once again makes for a smooth ride.
It also means you can't swap supplies without knowing the exact position, and why new supplies don't work right. Fascinating.
Meantime I fixed some more boards, most complex was one that had two supplies blown and 3 of the 4 drivers. Interesting.
C
Yeahp, I get that same feeling when looking at the register configurations on each DCDC. It seems they have each pair of DCDC's for a die set to be a current sharing group and auto phase control is turned on for the pair. Furthermore, each pair has its own unique group identifier and unique interleave setting ... which may be the phase variance between each group you mention. If not then theres some other group registers that seem to be configured similarily. I imagine if someone wanted to swap the 40A ones for the 50A DCDC variant, all they would have to do is ensure the configuration of each is copied over. When I spoke w/ Ericsson, they have a usb-pmbus adapter which you could use to hook up to the 10pin connector on each cube, this can be used to run their free gui software suite for configuring the DCDC's. Fascinating stuff to say the least. Also, Im happy to report my Titan is now going on 203+ hrs of uptime w/o any dies going to sleep ... think this is a record. Been like this since I changed to 200khz switching freq, could just be coincidence tho w/ some cable rearrangement on the power side of things haha! Also, DCDC's are still bout 2-4C cooler each. One thing thats also different which I didnt think of before is ... since I updated to 200khz and RESAVED the USER_STORE_ALL values for each DCDC ... that means my custom voltages are now set in the USER_STORE_ALL ... so from the very first power on of the DCDC's they are supplying the specified voltage to the dies(not default voltage which I think is .85v) and not waiting till the rpi boots up fully to run waas to set voltage values from the advanced.conf file. I have no idea if that would really affect anything. |

The only "real money" that exists today and has been used a money for thousands of years is gold & silver. So, the answer is NO ... cryptocurrency cannot make something physical ... simply "disappear".
If youre talking about FIAT CURRENCIES(not money) .... then yes, theres a slight chance ... in a world w/o central governments ... but since thats probably never gonna happen, theres always gonna be some form of fiat government backed currency.
.. I really wish people knew this difference between "currency" and "money" =/
