Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

Since looking at Bitcoinity, I see they have a section for trading engine lag. Might I ask that when I normally place an order and it's executed by the second I refresh or even after 5 seconds, is that the real "normal" time then?
What do you guys feel is an acceptable amount of delay or what is normal? Under heavy volume I suppose it can't be instant all the time but a 20+ second (or 20 minute) delay is simply not good.

Oh Loaded, who art up in Mt. Gox, hallowed be thy name! Thy dollars rain, thy will be done, on BTCUSD. Give us this day our daily 10% 30%, and forgive the bears, as we have bought their bitcoins. And lead us into quadruple digits

I would say a <20 execution for market orders is acceptable if its the same for everyone, i get the feeling that bots making use of the api directly have an unfair advantage, for example theres people on this forum using a penny bot but i cant trade in those small amounts through the web interface, for a penny bot to be successfull i imagine they have to execute trades pretty fast. but its the cancellation of orders that dosn't work, that is not acceptable for me. |

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."
- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'

You doing 600 sequential write TPS to the same table? Because Gox can't be issuing simultaneous txns -- all trades must happen right against the highest bid and lowest ask. If so, man... something is wrong with my database and right with yours! It can't be the matching... that's just popping the top element off a sorted list in RAM. Lock, pop, unlock. The DB write has the same exclusivity (lock) requirements but the op takes a LOT longer... Actually I suppose they wouldn't have to do it that way; all bids and asks could be in RAM only and just be lost in the unlikely event of a crash (no one would lose $). But based on the performance I think they are not... Edit: Anyway speculation abt this is fun but probably fruitless, Gox is making so much $ right now they aren't going to risk changing anything right now and unfortunately it doesn't seem like the market share will change b/c Gox has "shown" that they can handle holding onto the $ if not the txn speed. We need a trusted player like bitinstant to compete... Its just an informed guess on my part derived from writing the Gox stream to a RDBMS. When you say "producing 600 unique..." it sounds like you are telling me about reads. These can be cached, etc and so respond much faster... I can also run complex queries rapidly across the Gox data I've written to my RDBMS.
Not reads. Writes (update & inserts). I use the word "unique attribute" to ignore the composite keys. But transactional writes cannot be cached -- by the nature of a transaction they need to be written to persistent backing storage before they are acked. And of course its very important to commit a trade as a transaction so there is no chance that person A spends his $ or BTC but person B does not receive it. So essentially the DB performance is chained to the latency speed of the disk -- the time to "seek" and write a few bytes. But because the time to seek and write a few bytes is not much > then the time to seek and write 10k bytes, if the application chunks multiple operations into a single txn you get massive speedup. So even with writes its not the RDBMS, but HOW it is used.
Agreed. But any half arsed SATA (or probably IDE) drive should not blink at the tps produced by Gox. But it all depends on the db logical-to-physical mapping... Anyway, this is just a theory... but just watch Gox unwind a big market buy, ticking through 100's of .1 btc asks at a human readable speed and it becomes pretty obvious that each trade is handled individually. This causes all kinds of problem with efficient price discovery, like "fake" walls. Basically, it looks to me like a bot can use a bunch of .00X btc asks to slow down a big buy and use the time to take down the wall before the buy ticks up to it.
I reckon it is the front end matching algo implementation that is screwing performance. I hazard a guess they are suffering lock/threading issues. |

We're headed to a billion, boys.correction is now
I agree. We just hit 500 Million on the Market Cap. That's huge. We should see something happen right about now. Not a total collapse, but some sort of consolidation or retracement.

You doing 600 sequential write TPS to the same table?
No. Across (on average) 50 tables. The 600 attributes equates to about 80 rows. Because Gox can't be issuing simultaneous txns -- all trades must happen right against the highest bid and lowest ask. If so, man... something is wrong with my database and right with yours!
They should be able to. Consider a single buyer hitting 6 different sellers at the same price. It should be matched as a set and serialised sequentially. It can't be the matching... that's just popping the top element off a sorted list in RAM. Lock, pop, unlock. The DB write has the same exclusivity (lock) requirements but the op takes a LOT longer...
It's hard to tell what algo they are using but I am starting to think they have bids and asks in the same table and then attempt to pull data and match in <Language>. Personally (and given the lack of info), I would have spun the bids and asks into separate tables and used a JOIN for the matching algo. (You can tell I am a DBA because I shove as much data logic into the back end) Edit: Anyway speculation abt this is fun but probably fruitless, Gox is making so much $ right now they aren't going to risk changing anything right now and unfortunately it doesn't seem like the market share will change b/c Gox has "shown" that they can handle holding onto the $ if not the txn speed. We need a trusted player like bitinstant to compete...
Agreed. The worst critics are programmers. If I didn't write it, it sucks :-) |

There is something weird about looking a prices of things that you know the value of in dollars to then see the bitcoin value. I think I feel disconnected about the value of the numbers I trade back and fourth. Kind of reminds me of the cliché stories your grandparents say how they could feed the whole family on a nickel back in the day. It is going to be the opposite now with bitcoin, "you whipper snappers have it easy, you can buy a whole car with only a few bitcoins, back in my day a pizza cost 10,000 bitcoins!" |
