1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][ZEN] ZENCASH: Permanent, Distributed, and Fully Anonymous cryptocurrency on: June 05, 2017, 11:05:54 PM
Anyone else having issues with the Eleos wallet and/or importing the ZClassic wallet?  I have been running the ZClassic Swing wallet and have been trying to pull in the ZEN wallet.  Initially, I would try to pull in the wallet and would get a java error when it tried to restart.  After allowing it to fully sync, I was able to pull in the wallet, but every time I restart it, the wallet starts syncing at about 85% again.  I'm having similar issues running zend.exe directly, but I assumed the issue was that it wasn't quitting gracefully because Ctrl-C wasn't passing into the VirtualBox VM gracefully, but similar issues with eleos.

Also, after fulling syncing, I am not seeing any ZEN balance in the wallet, but I do have ZCL in the Swing Wallet, and I am copying the wallet.dat file directly from one folder to the other.  I have tried to do the ZCL wallet import and still have a 0 balance, so I'm striking out in multiple ways here...

I'd appreciate any thoughts/suggestions.

There is nothing on the blockchain on etherscan

Shows fully funded.  I got stuck at where to increase the GAS and didn't get in in time either.  Bummer.  I have been waiting for this for weeks.

From the whitepaper:

Maximum financing: 181,818.2 ETH -this may change with exchange rates.
• Minimum financing: 45,454.6 ETH -this may also change with exchange rates.
• Exchange rate: 1 ETH = 5,500 Basic Attention Tokens (BAT) -this may change
with ETH exchange rates.

Greets, Hank

This was updated in the blog post posted on May 29:   https://basicattentiontoken.org/bat-smart-contract-deployed/

We are pleased to announce that the BAT smart contract is available on the Ethereum mainnet.
The sale of BAT will begin at the time that mining commences on Ethereum block 3,798,640 and continue until the time that 156,250 Ether has been received or mining commences on Ethereum block 3,963,480, whichever is earlier. This is the “sale period.”
Based on current Ethereum block mining times, we estimate that Ethereum block 3,798,640 will be mined on or about 8:00 am PDT on May 31, 2017, and that Ethereum block 3,963,480 will be mined on or about 30 days thereafter.  For the avoidance of doubt, these estimates are provided for informational purposes only, and the sale period will commence and conclude strictly according to the block based definition above.

Look like ZEN difficult equal x2 Zclassic difficult   Cry

so disapointing  Cry

But one of the DEVs is enjoying his rum, so who would want to interrupt that?

The last info I was able to glean from Slack/Telegram is the devops team is working on resolving another error they found when trying to bring up the live-net related to the replay attack fixes they put in to appease Bittrex and avoid a DAOesque disaster.  

Timeline sounds like the chain should be live anytime within the next 24-36 hours for mining, but right now any miners showing successful blocks will likely be made invalid when the fix is put in.

As far as Bittrex, I've heard, but not verified that they will have trading live within 36 hours of the genesis block being propagated and the chain going live successfully.
Hey OC and other pool owners, what about this?
Can we still mine?

I'm unsure.. as said before, the pool is now finding blocks as I've hacked something together but the coins is still broken.. usually invalid blocks shouldn't be accepted by the local daemon
Suprnova is now finding blocks, i've hacked together something that it works.

Hashrate display is wrong, I'll fix that within 48h !

thanks for your patience


Thanks OC, would you recommend leaving my miner pointed at supr overnight or is this likely to make me rage in the morning?

Also could someone link me to a block explorer for Zen? I can't seem to find one. Another thing that should be provided at launch.


i think you should be fine


OCMiner, the suprnova ZEN pool is showing block height at 110009, but the node I am running is showing that the block height is stil 110007, so I think something still isn't right?  Thanks for everything you are doing to try to get this resolved.  The efforts are sincerely appreciated.

Hello,

I have a somewhat similar setup in my 2 car garage as well.  I have 46 x 400/500 GPUS all mining.  I also have a set of those exact fans behind my rigs.  I keep both garage doors opened about 4 - 5" and have a couple box fans trying to pull some cooler air in, and not enough clearance for someone to crawl in.  I have considered buying a couple carpet drying fans to see if they help pull cooler air in, but I haven't done that yet.  I don't have the same issues that you do with the heat being 100 deg F (I'm closer to mid 80 - mid 90)

A couple of additional thoughts:
   - I would rotate the PSUs 90 deg so they are more flat.  This may help with the air flow
   - I would push the rigs back so that the GPUs are closer to the fans.  On my setup, I created alternating shelves and have the PSU/MB on one shelf and the GPUs on another shelf.  I used 2 sets of the inexpensive $40 Home Depot shelving, but cut the vertical tubes in half.  It created a pretty nice, dense setup and because the posts are 1/2 length, it's really rigid too.  On your setup, rotating everything 90 degrees and having the fans behind the GPUs and nor passing through the PSU/MBs may field similar results?
   - I would also look at how the fans line up with each rig.  The middle of the fan behind the plastic disk moves less air then the outsides.  From top to bottom, I am thinking rigs 2 & 4 may be having additional issue for this reason?

Hope this helps,

Another difference to me is that the 7970 cards were in the ~$550 price range if I remember correctly, and with the 400/500 cards that can be found in the $200 - $250 range, the ROI is still very strong for GPU mining.  I started GPU mining BTC back in 2012 and 'retired' from all mining back in mid-2015, thinking that that particular ship had come & gone and got back into the game in early 2016.  I'm as bullish about GPU mining now as I have ever been.  I feel like for the foreseeable future there will be something worth mining with GPUs for quite some time.

Basically its like deja vu all over again like in Winter of 2013.

The RX470/570 which is the 7970/R9 280X equivalent is sold out globally and nowhere to be found.

The RX570 basically makes exactly the same profitability as the 280X did back in 2013. Actually a little more profit since it uses less power than scrypt.

From those of you that weren't around. Mining was crazy profitable at the beginning of 2014. A 280X made somewhere around $7-8USD/daily. Fast forward 6 months later in Summer 2014, it was borderline profitable since it consumed more electricity than made profit.

What killed GPU mining back then were introduction of Scrypt ASICs which made the difficulty skyrocket exponentially and combined with the MtGox bankruptcy and falling BTC price.

Now since its 2017 there are many factors that can kill these amazing profit-abilities.

1) Ethereum goes POS or reduces its block reward.

2) Ethereum (ZEC) prices crash.

3) Bitcoin price crashes due to hard-fork UASF

4) Difficulty skyrockets. This I doubt since ASICs are very difficult to manufacture and sales of GPUs only provide linear difficulty growths. Currently there are GPU shortages which are capping the difficulty growth.




Gpu will flourish  and BTC will fade a bit.

It is not at all like 2013

first off alts have more value then btc does at the moment .

and this is a new thing  never happened till now.

http://coinmarketcap.com/

Market Cap: $77,116,169,677

of which Bitcoin   $37,205,556,335

this means   $39,910,6133,342 is alt coin

as recently as Jan of 2017 btc was well over 70%
now under 50%

the question is will btc ever be the giant it once was?
not what will kill the alt coin market?

Of course as usual I am often wrong.
one of my worst predications made  was the iPad would be a failure and never do well at all.
