6  Alternate cryptocurrencies / Altcoin Discussion / Speed or "transaction speed" misconceptions on: May 03, 2013, 04:18:09 AM
Ok there seems to be a huge misunderstanding running around about transaction speeds, which coin is faster, etc etc.

Speeds are a function of security, how long it takes before a transaction is considered "final".

Here is what affects security (and as a consequence, speed) -

1. Total Hashrate
2. Time

Nothing else. Not the number of confirmations, block times, nothing.

Now, #1 affects security because it determines the likelihood of an individual gaining a significant portion of the total hashrate. Obviously it's easier for someone to gain 50% of the SHA2 hashrate for a coin that has a network  hash rate of 1 GH/s than it is for 1000 TH/s. Number #2 is important because as time elapses, the probability of someone achieving a higher block count and successfully forking the block chain lessens.

So why the speed of confirmations have nothing to do with it -

Confirmations are simply announcements of a progress of time. If I get a conformation every 1 minute, it would take 5 conformations to be as secure as a single confirmation being given once every 5 minutes. Just because I'm updating you that time has elapsed more often, doesn't mean any more time has elapsed. 5 minutes is 5 minutes, regardless if I notify you in 10 second progress updates or a single update at 5 minutes saying "done". So, let's say we have two coins. Coin A has blocks every 1 minute. Coin B has blocks every 5 minutes. Both have an identical hash rate. After 7 minutes Coin A has 7 confirmations, Coin B has 1, which is more secure? They are both exactly the same. They have the same hashrate, and the same amount of time has elapsed. "Faster" coins simply because confirmation times are lower are a myth.

So, as a result...

CHNCoin is not faster with 1 minute blocks.
Litecoin is not faster with 2.5 minute blocks.
If anything, Bitcoin is the fastest as it has the highest total hash rate.

Please stop spreading this myth.

9  Alternate cryptocurrencies / Altcoin Discussion / Offering Escrow Service on: May 02, 2013, 08:45:26 AM
Well I've seen a ton of people get scammed on this forum and quite frankly I'm getting pretty sick of watching people lose out. As a result I'm going to try and do something small about it. I tend to be on here a lot, and when I am I'm willing to offer myself as an escrow service.

I'm not prepared to do anything complicated. Basically you PM me with what the deal is. X amount of coins from person A for Y amount of coins from person B. You send them to me and I pass them on to the opposite person once I've received payment from both sides. If there is any mucking around, lack of payment etc I simply refund your money and so on loses.

So, that's what I'm offering. Hopefully it can help others out. Can do most of the major coins immediately and ill chase up some other wallets if needed. (Have BTC, LTC, FTC, CNC).

So some questions I feel I'd commonly get.

How do I go about it?
Work out a deal with someone and once both parties are ready PM me with the forum name of both members of the deal and the exact agreement. I will reply to both parties with the addresses you need to send coins to so you can track it. Once received the coins are exchanged, otherwise refunded.

Why should I trust you?
I've got some trades here, but other than that its simply a case of having a lot of time invested in the forum and not willing to waste reputation and lots of hours of forum time for silly amounts of coins. In addition if popular I hope to eventually introduce a token fee of something like 0.5%, so ripping anyone off cuts my own throat with that regards. Finally, if it makes you feel more comfortable I'm happy to do it in small increments (say 20% of the deal at a time).

What of you're not on?
As you can see by my forum time I'm on a lot. I'm in the AEST timezone so that should give you an idea of when I won't be on. You have the choice of PMing me and waiting for me to reply or finding someone else. Otherwise when I'm online it should only take time between instantly and 5-10 minute.

Since its free what do you want in return?
At the moment all I ask is after a successful use of the service both parties come back and vouch all went well.

So, not much more to say, the offer is now open.

12  Bitcoin / Mining speculation / List of ASIC power coming? on: April 22, 2013, 10:41:36 PM
Hey all,

I'm trying to come up with a slightly more accurate forcast of what's going to happen with mining difficulty in the future. As a result I'm trying to compile a list of known ASIC power that will be coming online at some time in the future. If there isn't a list out there I'm happy to compile a list in the OP here, if you could help me out by posting the TH that the group / company is planning on adding, it would be greatly appreciated.

So..

ASICMiner:  50 TH/s short term, 200 TH/s long term
Avalon Batch #2: 36 TH/s ?
Avalon Batch #3: 36 TH/s ?
Avalon Chips:
BFL: ~ 375 TH/s ?
100th: 200 TH/s ?

Miss anyone?

Cheers.
13  Economy / Service Discussion / MtGox - AUD -> USD? on: April 18, 2013, 11:11:49 PM
Hey. Aussie here, deposited to MtGox using local bank deposit, and as a result obviously my funds were put in as AUD. The AUD exchange seems pretty dead though, and I was hoping to convert my money to USD. Is there any way to do this on MtGox?

Cheers.
14  Alternate cryptocurrencies / Altcoin Discussion / All GPU's Settings / Results Thread on: April 18, 2013, 03:06:48 AM
I humbly suggest we have a consolidated place to post what type of card we have, what settings we're using, and what the results are.

This aids in others trying to fine tune their card for optimum performance, and gives a good idea of what to expect in terms of hashrate. Please try and keep on topic so it's more of a reference for people rather than a discussion surrounding it.

Suggested standard format.

Card(s): 7950 x 4
Algo / Coin: Scrypt / LTC
Miner: Cgminer 2.11.4
Config: --thread-concurrency 24000 -I 18 -w 256 -g 1 (otherwise stock)
Results: 500 kH/s per card - Temp ~75c
Comments: Using Catalyst 12.8, APP SDK 2.7, ADL SDK 5.0
15  Bitcoin / Mining support / Poor Unbalanced Performance - 7950 x 4 - Litecoin on: April 15, 2013, 10:58:41 AM
Hardware
4x 7950, 8GB of Ram, FX-6100 processor.

Software
Catalyst 12.8
ADL SDK 5.0
APP SDK 2.7
Xubuntu 12.04
CGMiner 2.11.4


What was happening before -
Previously I was running this rig with 3 cards. I was getting ~1.5 Mh/s - 500 Kh/s per card. Not mind blowing, but acceptable. I was using the following command to start.

Code:
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

./cgminer --scrypt -o stratum+tcp://stratum.give-me-ltc.com:3333 -u username -p password --thread-concurrency 24000 -I 18 -w 256 -g 1

What is happening now -
So now I've upgraded my rig by adding an extra card. Instead of getting gains it seems my cards are simply running slower apart from GPU0.



It seems even at lower intensities now it's mining unevenly (@ I=13)



Instead of getting 500 Kh/s I'm getting ~ 350 - 400 a card, even though with the same settings before I was getting 500 (same as GPU0). Can anyone suggest trouble shooting methods or ideas as to whats going on?

Help appreciated.
16  Bitcoin / Bitcoin Discussion / Why are people complaining about manipulation? on: April 12, 2013, 12:12:13 AM
Seriously, it's a free market.

To begin with, I'm not even convinced that there is huge manipulation going on. It's just a way for many around here to justify getting burnt and being wrong about the growth of bitcoin this week. If anything bad happens suddenly it's a conspiracy, banker manipulation, secret DDoS attacks rather than simply bitcoin went up, was over priced, corrected itself.

But let's say for argument sake there was some form of manipulation, someone wanted to spark 'panic selling' or whatever your flavour of conspiracy is... so what?

No one forces you to buy, no one forces you to sell. If you follow the heard in a crash then you can't blame others for being 'manipulated', you made the conscious decision to do the same thing. Bitcoin as a currency is still fine thanks to services like Bitpay who insulate merchants from the volatility. Why do we need any protections at all? Why are people suddenly trying to suggest regulation, simply because they got burnt?

18  Bitcoin / Development & Technical Discussion / Bitcoin API? (Bitcoin-QT?) on: April 10, 2013, 03:35:40 AM
Hey all,

I'm looking to try and detect when someone sends me a transaction, and take actions with a little python script.

Does anyone know how I could do this? Is there some type of API call for bitcoin-qt or something like that to do this? Are there alternative wallets that would allow it?

Sorry I know this is very very basic, but I'm just looking into it for the first time.

Cheers.

Can post pics when I get home. Feel free to ask any questions.

Cheers.  

20  Bitcoin / Mining speculation / Will we ever see a reward split? on: April 09, 2013, 03:22:38 AM
These days it's almost insane not to mine in a pool, simply because the amount of rewards (solving a block) to the amount of attempts (hashing power) is so crazily high it would take months for an average person to be successful. This creates the need for pools to combine hashing power, and on average hit the reward more often, then more fairly distribute the rewards among the pool.

Now this is starting to create a few issues. With the centralized nature of pools we're loosing more and more nodes on the network, as people aren't willing to solo mine given the likelihood of no reward.

As a potential solution would we ever (or could we ever) see a situation where the reward is dramatically lowered, but the amount of blocks dramatically increase? For example the reward might drop to 0.25 per block, the amount of blocks raises by 100 times, and the difficulty would lower by 100. This would open up the possibility of solo mining for many more people, yet leave the core fundamentals of bitcoin intact (limited currency, etc). The advantage also is more nodes to help with network resilience.

So, I suppose what's the downside?
