ztex already discribed that in his threads, hashrate will be adjusted as error rate changes. Try typing c to set error rate to 0 and hashrate will rise and adjust again as errors occure. It will not make hashing more effective after all.

umm.... "type c"? i had so far the feeling the application wasnt exactly interactive.. and as of now i cant see anything change when typing c.

Thing just is it makes SOME difference here.. it adjusts up to 220MH when starting at night and keeping that way at colder temperatures but drops then, at day to 205 to 210MH at day without ever raising again when it gets colder.. thats what i find a bit odd.

Is anyone using that bitstream on Ztex Singles? Would like to know if it is somehow usable

Totally stupid question about the miner: Does it change the Mhz also upwards? I only see the speed increasing after starting it and then lowering it to a stable value it holds for days in a row, ignoring outside temperature or error rate..
Is that normal behaviour or is there a chance to make it increase speed by itself?

can the btcminer used with ztex single/quad for litecoin mining ?
I mined multichain on two quads without any problem. AFAIK there plainly is no difference in means of hashing, that's why it just works and also should with LC only.

How should the ztex work with ltc? i dont think its possible to mine ltc with fpga yet anyway..

Ausserdem weis ich aus eigener Erfahrung, dass es user im Board gibt, die Spiele auf ihre "fairness" prüfen... hatte schon einige derartige Besucher auf meiner Seite
Wie meinst du das?

Grüsse,

Naja, es gibt user, die entsprechende Seiten testen. Unter https://bitcointalk.org/index.php?topic=75883.0 findest du eine Liste der gängigsten Spiele. Virtualminer ist nicht drunter, da ich keine echte Gamblingseite betreibe - aber Deposit/Withdraw und mögliche Manipulationen wurden bei mir schon zu genüge getestet.
Ich habe demnach, ganz ehrlich, das Gefühl, dass es innerhalb der Community bereits eine art peer review gibt, die Spiele aussondert, die nix sind..

TO make it simple: Do what you would do in Bitcoin Wink

Create a rig, and then join a chain.. or a pool. Its up to you Wink
Ok, but how can I deposit Bitcoins into the game? Sad
My "Deposit Address" is empty...

ohh.. i see this is some bug coming from the new deposit system. will fix it in a few minutes!

Should be fixed. My bad!
I now have the address Cheesy
I will deposit something soon as I get 0.025 BTC Tongue

P.S: This is awesome! Cheesy

Edit: Deposited the amount required to buy a vASIC! Cheesy

Edit 2: lol, I have done so much edits here, and so much smiles...

Better to edit a lot and put a lot of smilies in there than once ranting and making the project look bad Wink

Das ganze klingt, tut mir leid, überflüssig.

Wenn ich echte ZUfallszahlen haben will, dann besorge ich mir die bei Random.org. Wenn ich ein nachvollziehbares Randomisiersystem haben will berechne ich einige tausend zahlen und hashes im voraus und lasse dann den user diese hashes sehen, wenn dieser spielt.

I wonder how you found the faucet. It has been disabled ages ago and removed from the menu 0o
I found it on Google Grin

Google has a way tooo long memory Wink

Hello,
Sorry for this, but I really don´t understand:
Is this just a game, or a game where you can really earn money outside the game Huh
Thanks, it looks interesting!  Wink

It is both. It is a game where you have to build up a mining farm and it is a simulation of cryptochains at the same time. You can earn money, but it is like with Bitcoin, Litecoin etc: You have to trade and make a tradeoff between investing and earning.

Added Poll: "vCPU only chains"

Question: Do you want to have different kinds of "hashing algorithms"?
In the real world there is sha256, scrypt, soiledcoin and some more..

So i wonder: is there any need for a modification that you can also add GPU resistant chains like scrypt (Now.. please dont discuss scrypt/gpu... thanks)?

vASIC prices are all 25% reduced till July 21st.

They seem to be the same price they always were.
Yeah.. i just checked it.. they SHOW the same price, but buying them is cheaper than regularly. My bad *changing this*



This is interesting as a concept and I hope it does well.So this is like:
1.Buying a 'virtual' mining rig which you then buy with BTC
2.Then buy virtual upgrades in hashpower to mine more coins.
3.You then exchange these coins for BTC/another currency.
If I understand correctly and explain this in a simplified manner,the steps I wrote above shoul more or less reflect what you're doing in this 'game'.
Thats the most basic idea.
The whole Virtualminer idea started back when Ixcoin, I0coin, Tenebrix, Fairbrix, Soiledcoin etc started. I was rather tired of this game that everyone needed to spawn his own little Bitcoin clone in order to test one or two features.. so back in the days Virtualminer was more aimed towards simulating a BTC like chain with somewhat changed parameters (payout, blocks till diff change etc). Within a short time very very early testers (Aug 11) found this to be rather a game then a simulation and since then i followed that idea and kept writing a game out of the main idea.


There are pros I see in this:
1.You don't need physical space to store regular mining rigs that physically exist.
2.No need to use electricity at your end so no utility bills for mining.
3.No noise and heat as this is hosted elsewhere and virtualised.
4.No need to constantly tweak and struggle with miner settings as this is all standardised (from what I can see) when you buy an upgrade.
5.You can still make BTC/alt currency while doing this.
That was yet another idea of having a total virtual cryptocurrency... for mining i0coin (e.g) people always removed physical mining power from the bitcoin blockchain and also chance was higher a newly created altcoin could get killed off by only a small amount of users. Therefore this total virtual approach

The only con I can see is that you need BTC initially to start off with but it's easy enough to acquire (buy at an exchange,mine them normally for we short while,offer services/products,etc) but that's kind of obvious since nothing is free without a catch.
Well... yes. You need BTC initially to start competitive playing - but the reason for this is simple: if people dont invest money, how should they give value to the chains? In real life you have to invest in mining equipment as well. If mining was completely for free Bitcoin had no value (in my opinion...). So this game bases arround the idea that users have to pay a little something in order to give them a feeling of "a coin has value". I have tried to strengthen this now by allowing to buy shares of the game with virtual coins, so users get real BTC for something they buy with virtual coins.

And thats one of the main problems with the game: with about 280 users there is still only a low amount of players who really invest time, and money and really try to make the chains work with some real value. Unfortunately the volume is so low that it is still cheat prone (sell a few days your own coins to yourself for a few BTC and you have the best selling chain) but i hope users can control that... at the moment the market is quite self regulating and i hope it will stay that way.. and of course that more people will join of course Wink


------
By the way. There was a short downtime between 2am and 9am today morning (CET) when the database somehow died.. nothing was lost though and the game continued normally.
437  Bitcoin / Project Development / Re: VirtualMiner 2.0 - Mothlabs vASICs have finally arrived! on: July 14, 2012, 10:30:43 AM
I think i found the exploit and fixed it...

Anyway.. i have now added some minor stuff to the game and finally added the option to buy shares.
Dividend will be paid every 1st of the month automagically and consists of Trade Fees and the fees for upgrading the global hashing power. Therefore some of the money flows back to the users. Shares can only be bought with actively traded virtual coins - it is somewhat cheat prone in a sense that you cant just buy your own chain up easily, but this has to be tightened.. but as i dont have a real 24hr volume (yet! i hope) i have to do some workarround. Once i have real 24hr volumes the 24hr average algorithm will change.

About the API: I am still quite busy here but leave me a pm and let me know what API calls you need.. i then will implement them.


*edit*
vASIC prices are all 25% reduced till July 21st.
438  Other / Off-topic / Re: Are you vaccinated? on: July 14, 2012, 08:41:57 AM
Got to just say one thing:

Vaccacines are a good thing if you put some common sense on them:

You dont need a Flu vaccacination every year if you are not prone to flu anyway. Never had a flu vaccacination and never had a flu even though i deal a lot with random people.
You dont need a hepatitis vac if you sue to stay at home 99% of the time.. but if you are at places that you cant be sure of water qwuality such a vac is indeed useful...
But you HAVE to keep your children vaccacinated - at least for those common "child" illnesses... Take Polio as an example.. its a painless vaccacination because children only have to swallow a cube of sugar yet people choose their children not to get vaccacined.. and here comes the argument i read above "If you dont vac your child, mine will get infected." Thats NOT bullshit.
In my extended family we had the case that a 2yr old was infected with Polio because some shithead had his son not vaccacined. That infected youth was 11yrs old - and vaccacination happens here at 6yrs to 8yrs.. he didnt "believe" in that stuff. Nevertheless his son died, that 2yr old is disabled for the rest of her life and who knows who else got infected.

So i just got to say: Vaccacines have to be applied with common sense, but since children dont have common sense they HAVE to be vaccacined till they can decide theirselfes and "Oh no.. i dont want no injection" doesnt count as "decision".

440  Local / Mining (Deutsch) / Re: Welche Voraussetzung braucht Hardware für optimale Mhash/s? on: July 13, 2012, 07:28:22 AM

... der effektivste Chip immernoch S6LX125 ist. Es gibt zwar alternativen (BFL Single) - aber deren Lebensdauer ist unbekannt..
Das ist aber kein Chip, oder?

S6LX150 ? Spartan 6 LX150 - doch doch, ist ein Chip - nur eben in Kurzfassung geschrieben. Wink


Frage:
Welche der FGPA Prozessoren kommen denn noch in Frage, oder werden von Leuten in gewissen Mining Projekten verbaut?

Has anyone tried the fpga miner on a Xilinx ml507? (Virtex 5 LX 70)
https://bitcointalk.org/index.php?topic=39536.0

Butterflylabs benutzt afaik Stratix Chips in ihrem Design aber die sind afaik die einizigen, die einen grundlegend anderen Chip nutzen.
Das Problem bei den FPGAs ist folgendes - man sollte nach Möglichkeit eine Logikeinheiten Menge haben, die nahe an einem vielfachen von 120000 ist.
Die Zahl kommt daher, dass SHA256 etwa 60000 Logikeinheiten Platz braucht - und Bitcoin macht SHA256(Sha256)), also demnach einen Berechnung, die 120000LUT lang ist.
Der S6LX150 hat 147,443 Einheiten und ist damit recht passend.
Hinzu kommt beim S6, dass er relativ wenig Strom aufnimmt und sehr gut gekühlt werden kann, was nicht bei allen FPGAs der Fall ist. WEnn du dich ein wenig mehr über die Dinger einliesst schau dir die Geschichte der Butterflylabs Singles an - dort stößt du auf genau das Problem, dass das Külen bei denen nicht immer optiomal war...
Hinzu kommt, dass ein einzelner Spartnaer  etwa 150Eur kostet (http://www.digikey.de/product-detail/de/XC6SLX150-3FGG484C/122-1725-ND/2339800) , der XC5VLX155 als erster Virtex5 mit mehr als 120k Logikeinheiten kostet 2000Eur (http://www.digikey.de/product-detail/de/XC5VLX155-1FFG1153C/XC5VLX155-1FFG1153C-ND/1957125).. ist damit etwas unfreundlicher fürs Hobby bei etwa selber Leistung.

Größere Chips gibt es natürlich auch, aber da der nächste wirklich große Sprung erst bei 240000Lut zu erwarten ist (2 hashes pro Takt) - derartige Chips aber unerhört Teuer sind bleiben viele beim etwas behäbigererem aber gut zu benutzenden S6LX150. Eher erwarte ich da, dass es irgendwer schafft die Codes so weit zu verbessern, dass sie weniger als 120k Lut brauchen um einmal durchgerechnet zu werden beziehungsweise anderes berechnen, so, dass das ein wenig effizienter wird - da arbeiten im Forum ja auch einige dran...
