So....  move too fast and we maybe introduce a forking bug or a security vulnerability.

Move too slow and maybe we get fired-- somebody faster at incorporating safe changes releases their own fork.

For me, "move slow" is the right answer.

But I would be completely happy contributing patches to somebody else running a fork who solves the "move fast but be safe" problem.


Ok, start a "Bitcoin-QT Poweruser" fork, and let people submit their heart's desire. Without you doing this it will have 0 credibility, including from me.


Edit: Hope you're not coming in from above just to go back again after you said only 2 words.

Why don't you make a bitcoin fork, but not a network fork?

Here is a response from gmaxwell regarding at least one of your questions (max size).

https://bitcointalk.org/index.php?topic=154682.msg1667934#msg1667934

Thanks, then if the minimum currency unit was .01 the max unspent outputs would only be 44 gb

You want people to be only able to spend ~$1 (at current ex rates), and likely $2-$10 later on?

Amount of noise unit generates is important concern for me and few guys I know, all of us aiming to become ASIC miners.

Why? Covert mining?
Mining at home maybe. I love the word 'covert mining', makes me think of someone sneaking into a library or electronics store and mining..

Hi there,

Possibly an obvious answer to this, but I only have a small investment on bitfunder and would like to make new investments on the basis of dividends paid per share price (maybe last dividend/share price) or even on %. Without clicking on each share and reading the amount is there an obvious way to sort the shares? (I am viewing the website on an ipad and maybe this information is scrolled off the right of the page?)

Thanks!

Myrdd

You can click on 'My Assets' and 'Dividend Reinvestments' tab.
You can pretty much set everything there. Smiley


Thanks! But I am looking to diversify and invest in shares that I do not already own. I have often looked at my existing dividends (quite happy that my bitcoins earn more all by themselves!) but I would like to invest in other shares (that I don't already own) based on return dividends.

Thanks again!

Myrddin.

Shameless plug for BTCINVEST - it invests in good dividend paying assets and loans / lines of credit Wink

Also, widely used hashing algorithms are not an "unknown algorithm". hashes are the core of bitcoin.
Yes and this is good so. But does not have much to do with the distribution of its random numbers.


"Provably Fairness for Dummies"

1. casino generates a random string, called the 'secret'. Use whatever random system you're using now.
2. hash("sha256", $secret). Show it to the player.
3. player provides their own secret, via txid, or normal input. Generate player's secret by collecting mouse movement. Let player specify their own secret.
4. output = hash("sha256", $casinoSecret . $playerSecret)

Of course you are underlining the advantages of "provably fairness" as you self advert for such a casino. But the problem lies in the $playerSecret. A hash calculated on the clients computer does not provide as much proof as you tell. It can be manipulated too. To exclude that you have to make statistics too what needs the same amount like every statistical proof else. As long as such a "provably fairness" isn't certified by a trusted 3rd party it's not so "provable" as it seems for an customer.

If the hash $playerSecret comes from a 3rd party like the bitcoin network it is a legit process to use this to make a gambling service provably fair. But as long as the $playersecret is generated by some shady javascript on the casino website the "provably fair" is not as proved as you say.

Yes we could implement a "provably fair" algorithm, but it only would suggest the user a security he can't have. So we decided that the user should decide on realistic parameter if he wants to trust us or not.

The user should always be aware to get cheated on the internet. And we don't want to lull our customers into a false sense of security with algorithms which only look good.  


But everyone can see their JavaScript code. I can modify the code so I pick my own secret. bitZino let's you do that with a user interface.

By the way, learn about double spending, before someone runs off with your entire wallet. I bet you haven't modified bitcoin.conf to prevent trivial double spending attacks. There's a reason why the biggest bitcoin gambling game now pretty much requires 1 confirms, and it is for a good reason - because you'd be losing money otherwise when you get large enough.

Thank you for your concern.

This is why we only pay out if we have three confirmations. But you can play with zero.
Seriously? No, you cannot show results for 0 confirm bets because I can doublespend if I lose, and not doublespend if I win.

Now read more about Bitcoin.
5710  Economy / Gambling / Re: Diceeno.com on: March 29, 2013, 12:23:56 PM
Well we have discussed the provably fair topic for a long time, during the development process. And we concluded that the only real proof is to make statistics with the transactions log. Everybody who knows statistic will very quick recognize if something is not fair on the casino.

As we don't have a payment for every bet we can't use hashes from transactions to generate random numbers.

We studied the „provably fair“ solutions on the Internet which came without such a transaction hash. Normally there are some hashes generated on the server and some on the client. Those calculate in a known algorithm and a huge documentation of all calculations give some feeling of proof.

Everybody who tried to generate a random number with a mathematical formula knows the challenge. In fact it is not possible. To generate a random number you need the most unpredictable event as possible what contradicts with the philosophy of math to predict everything. So we normally trigger physical events like the memory or CPU usage to make the random number less predictable.

To get the most unpredictable random number for diceeno.com we have implemented a hardware application which measures the noise on a Diode junction. With that we initialize our random generator. This gives us a very realistic distribution of random numbers. The prove of that lies in making statistics.

We won't give the feeling of a proved security because this just does not exists. The only proof that a casino is fair lies in the played games. And we hope that the users make their statistics while playing and check the fairness of every casino they use and don't just believe in some white papers distributed by the casino owner never certified by a third instance.


Oh god, another casino operator thinks provably fairness is pointless again. Seriously.

Statistics can be faked. How do I know the house isn't making up fake bets where they always win, just so it appears it's fair? It is impossible to prove that a casino is fair via statistical analysis unless you play hundreds of thousands of games yourself. Statistics are not a plausible way to verify fairness.

Also, widely used hashing algorithms are not an "unknown algorithm". hashes are the core of bitcoin. They're how the blockchain works. They're how mining works. Without hashes, there would be no mining. Hashing systems aren't magic, they are pretty much used everywhere.

"Provably Fairness for Dummies"

1. casino generates a random string, called the 'secret'. Use whatever random system you're using now.
2. hash("sha256", $secret). Show it to the player.
3. player provides their own secret, via txid, or normal input. Generate player's secret by collecting mouse movement. Let player specify their own secret.
4. output = hash("sha256", $casinoSecret . $playerSecret)

You don't need TXIDs for provably fair verification! TXIDs are commonly used as a secret, but it's an option.

Process output how you wish depending on what your game is. As long as you publish how you generate it, it doesn't matter which way you do it, because as long as any party and verify the result it's OK. Like I can say "0 is heads, 1 is tails" or "1 is heads, 0 is tails", or even "if fourth bit is 1 and second bit is 0 then it's heads", as long as anyone can verify it then it's provably fair. Provably. Sure the casino can have 1% breakeven odds, but everyone will be able to see AND VERIFY that before playing.

Provably fair casinos when done right cannot cheat without being caught.

The only logical conclusion for sidestepping provable fairness on a dice game is that you are trying to cheat, or you are too stupid to implement a hash function. Statistics cannot feasibly prove you are not cheating.

Apologies for the rant, but I have never seen more concentrated "studying" ignorance or shenanigans.  

By the way, learn about double spending, before someone runs off with your entire wallet. I bet you haven't modified bitcoin.conf to prevent trivial double spending attacks. There's a reason why the biggest bitcoin gambling game now pretty much requires 1 confirms, and it is for a good reason - because you'd be losing money otherwise when you get large enough.

Due we faced much more traffic than we expected, the server crashed. A hardware upgrade is on its way.

The user gets a log with all his transactions. The statistic will prove that it is fair.
Why not just make it provably fair?

We include whatever fees bitcoind includes automatically.

Are you sure? I've never seen this happen when I use the defaults in the satoshi client. Here's my transaction, still unconfirmed, maybe 3-4 hours after it was sent:
https://blockchain.info/tx/6543e55d8c83b26d84adfaab78aa4354b0b546697b43b278682344457b6b84fc

Positive.  I'm not sure what's been up with the network lately, but I've noticed crazy delays on a lot of transactions.  Maybe we should set a fee on all transactions.
Growing pains? The bitcoin network is getting bigger..

Thanks for the tip, but I thought bitinstant was having major problems? The other problem for me is that I live in rural wisconsin and don't have constant access to transportation. Even the closest wallyworld is 35 miles away. We have no BOA...etc. Its ruff.
Bitinstant was (and might still be) having major problems - hit or miss really. But if you contact them you should be able to get any problems resolved.

Srry guys, I meant to buy. He has a great rep, and a post referencing selling. Worked with him before, on a sale, NOT A LOAN.
I explained in my post why I decided to try the loan option when I actually have the cash to buy. I know its a bit confusing. Now I feel like I may have said too much or something. Im not really sure where to draw the line when it comes to discussing transactions. Hope I didn't just fuck up!
Look, I live in the middle of no where, no working vehicle. Nearest wal mart is 35 miles away. No BOA...etc. On top of all this, I am trying to get these before the weekend, hopefully tomorrow morning. Had a chance tonight, but it only came through after stores were closed, so no mp or wu.
Do you have a credit card? Try btcQuick if you do.
5719  Other / Meta / Re: Considering BTC exponential growth... on: March 29, 2013, 05:05:29 AM
and at least the UK house price fell alot 10% +

unlike Australia where it fell 1% or stayed the same or goes up still!

in Australia property is the religion

Australia's practically the most expen$ive country on earth now (outside Japan, Monaco and a few others), especially Sydney and Perth - it's unbelievable. (OT) I'd still like one of your women, though, whether or not you're still wont to refer to them as "sheilas" in this day and age. Grin
Definitely. In most good suburbs, houses are 800k ~ 1.1 mil..

Cost living is also high, but so is wages

Data centers in china are extremely expensive.  It isn't a 1:1 comparison.

All the more reason to start looking for cheap power at data centers outside of China.

Iceland, Canada, Washington, and Nevada all have cheap power.  So do Belarus and Ukraine, from what I hear around here.
Currently it might be more worthwhile to deploy it in China for faster turnarounds - no shipping, export/customs issues ..
