Sounds like you're running out of RAM.

No, I know you can't. I hope the following clears up what I meant.

Yeah, I meant I was just noting that I didn't know you couldn't just transfer in one transaction.

Announce that I won the lottery.

Although you're sourcing that from a wiki dictionary and not a word authority like Merriam-Webster, I agree. Just be aware that your usage of digit in your details page is a bit vague if you don't specify the hexadecimal numbering system.



That's odd, I didn't know you couldn't just transfer whatever balance you had.  Well with all the hackings and malware going around if I won I wouldn't publicly announce it.  Looks like you're running the most popular lottery, I don't think anyone is even close to $1,200 USD in payouts.

Ah alright, just I misinterpreted "digit" as a traditional 0-9 number, not as a hexadecimal digit.
I see you transfer the payment via 1 bitcoin transactions, that's an odd way to do it.

1% is a really small operator's fee, it might be wise to take a bit more to invest in advertising and to put some coins as the jackpot minimum at the start of every round.
both would benefit the players after all

Sorry about that, don't know how I missed that page.


I'm not sure I'm clear on the formula yet.  What exactly does the secret hash mean?  I don't see a reference to it on the details page.
Did the winning picks come from the secret hash? or did you hash block1 & block2 together?
If the only relevant part of the winning picks are the digits, why does "ec" win? Those aren't digits.


cheers

This is an interest debate. I've read through Bitlotto's website and statements in this topic, and I've found a way he could cheat.

The algorithm he uses to compare the sha-256 hash of the block hash and the mega ball number, against the transaction hash.  I haven't seen any place where he's disclosed this algorithm.

So as of now he could be cheating.  This is easy enough to fix though, by just disclosing the process so anyone can replicate it.

I'm working on a new Windows & OS X miner.  The goal is to provide a user friendly miner for people new to bitcoin, that can be installed and run on either platform without a problem. I'd appreciate some help, it's not an easy project.

thanks, that's an excellent suggestion.  seeing how we're dealing with random numbers and the doors aren't guaranteed to have prizes I don't really doubt that statistically this method is completely unsound.  However I didn't know about chi-square tests and I've got other ideas I'd like to map out using this method.

When the host picks the right door at the start you win. No more need to switch.

When the host picks the wrong door, then what exactly is the situational difference between this and the monty hall problem? In both cases you've gotten one wrong door open, and two doors closed. That gives you 2/3 of a chance if you switch.

I wrote a C implementation, source here http://pastebin.com/PN2k6HZP

Basically it makes a hash from a random number between 0-99,999, then the number is found via two methods, each run 99 times.
The first method is an implementation of the monty hall problem.
The second method is purely random.  Neither ever tests the same number twice.

example output

Most times I ran it the monty hall implementation ran with the lowest average tries, but when the purely random method won it would usually win by a larger margin than the monty hall problem.

Many of you may be familiar with the three doors problem, aka the Monty Hall problem. (info on wikipedia).

Basically it states that you have three doors presented to you, one which holds a car behind it.  You pick one giving you 1/3 of a chance of having the right answer, but then you're presented what's behind one of the doors you didn't pick, and it's not the car. If you switch your pick, your chances of being right increases to 2/3, instead of your original chance of 1/3.

Here's the results of a simulation


So what if we give miners the monty hall problem? We could increase the chances of finding the right hash by a nice margin.

So in a pool you could effectively have it so 90% of miners ditch 1/3 of the hashes that need to be tested, and 10% of the miners work on the ditched ones.

so how many hashes/sec can you get with the actionscript?

looks like the chinese manufacturers don't need much convincing http://www.alibaba.com/product-gs/453448294/AMD_ATI_Radeon_HD_5970_D5.html

they're selling $35-$120/unit, with a supply ability of 8,000 a week

I've been working on this.  I'm very familiar with Actionscript 3, and ABC - Actionscript ByteCode, having written a decompiler & flash injector.
However I'm getting familiar with the bitcoin protocol and code right now, so no ETA for the moment.

That's quite a large and risky investment.  Why not invest in mining hardware? You'd get your bitcoins, and keep profiting.

Wow, I thought paypal didn't allow USD->BTC transactions because it was alternative currency... but linden is fine?

Speculation like this is likely to drive the market up.  While it may seem good to be getting all this press, the negative attention from US senators and the labeling of bitcoins as a hacker's currency by the guardian makes bitcoins seem like something illegal.  The public doesn't understand the concept, and with the cryptography aspects it's likely to never understand it.  I think what we'll continue to see will be biased and uninformed reports, including fear mongering about the illicit drug trade, money laundering, and about a potential pyramid scheme.

well that's interesting, but they should re-do the video with actual voice overs instead of robots

thinking about mining, but it looks like all 6990 cards are sold out.
