1  Bitcoin / Mining speculation / I know it's too late, but aren't we shooting ourselves in foot by buying ASIC? on: June 21, 2013, 10:16:32 PM
Buying ASIC miners goes against the common good. It give an individual the upper hand for a while until most miners upgrade to ASIC. By that time, a 5Ghps miner will give the same a amount of bitcoins as a 200Mhps GPU miner gave 6 month before.

In the long term, we all loose and the only winners are the ASIC manufacturers.

This is a fine example how group behavior eventually goes against the common good.

But I guess it's too late for that now... the hash rate snow ball is rolling faster and getting bigger by the minute.

אתה רציני?! למה שמישהו ילווה לאדם זר? איזו יכולת גביה יש לאדם מן הישוב? זה לא שוק אפור כאן Smiley

אתה רוצה, תשלם ותקנה.

היום יש FPGA של ALTERA בטכנולוגיות של 22nm. הם אמנם יקרים בטירוף אבל נותנים ביצועים לא רעים בכלל לעומת ASIC בטכנולוגיה של 65nm כי על אותו שטח סיליקון יש פי 10 יותר שערים לוגיים.

אם אתה רציני, תתחיל עם FPGA מהדור החדש. המעבר מ- FPGA ל- ASIC הוא יותר קל. מה גם שזה פחות מפחיד משקיעים כי אתה יכול להראות תוצאות תוך כמה שבועות.
לפתח ASIC מהתחלה זו השקעה מינימלית של 4 מיליון דולר, לא כולל עלות שכר מהנדסים.

It seems there is room for more start ups like coinbase and bitpay to offer such solutions.

If I generate addresses on the fly for each transaction, this mean I have to save the key to each address on the server. For many small business the use shared hosting, security will be a major issue.
And even if I have an address for each transaction, one can still figure out how much I am selling. I will have to turn those coins into fiat money in some market. So I will have to transfer them to some main address...
If I generate the addresses offline, it solves the security problem. But I don't see a way to hide my income from a determined "spy".
Bitcoin may be anonymous, but its open ledgiure blockchain may eventually kill it.

You are right

ok, understood.

I am not a troll but I am skeptical.
I understood bitcoin is that one should hold a few addresses and use them, but I was wrong.

Considering them as a one-time transaction id makes more sense.

My store is not in English, but you can take a look at www.zolkan.com

Does it matter if it's ASUS, ATI, AMD, Sapphire? Or all that matters is that it's HD5750 Radeon?
12  Bitcoin / Development & Technical Discussion / Can bitcoin support a blockchain that is 1000 times bigger? Is it scalable? on: May 09, 2013, 02:10:04 PM
The current blockchain is about 10GB big. What's gonna happen when bitcoins become what we all want it to be? We are gonna have 1000 times more transactions a day. The blockchain will become a monster. Can the bitcoin network/clients can handle such a huge blockchain?

I am sorry to say, but it not user friendly at all.
Keeping track of so many addresses can be a real pain especially if I am a successful shop with 10 - 100 transaction a day.
It seems that bitcoin is not suitable for large scale # of transactions.


14  Economy / Trading Discussion / As a store owner who accepts bitcoins, anyone who wants can track my income on: May 09, 2013, 12:29:53 PM
I decided to accept bitcoins in my online store only to realize that anyone who wants can type in my wallet address into the block explorer and see each and every transaction made to my address. This way, anyone can know hoe much money my business is making.  Today I obviously keep this data secret and never publish sales data...

Isn't that a HUGE reason for businesses not to accept bitcoins?

I am interested in BitForce 5 GH/s SC, but I can't figure out their current status... do they ship now? if not, when? do they actually work?

Thanks for the answers.
17  Other / Beginners & Help / Re: What reason does a miner have not to choose as many unconfirmed transactions? on: April 25, 2013, 04:11:21 PM
Isn't it in the best interest of the network that each block will contain as many transactions as possible? Why make transactions wait? If it takes the same effort to create a block with 10 transactions or 1000 transactions, why the system does not enforce choosing the the latter?

Theoretically, a node which has considerably more computing power vs the rest of the network, can choose to include 1 transaction with each block, deliberately delaying confirmations (or controlling them)  since it has the biggest chances of finding a new block...
18  Other / Beginners & Help / What reason does a miner have not to choose as many unconfirmed transactions? on: April 25, 2013, 03:25:20 PM
When mining for a new block, the miner choses unconfirmed transactions to include in his block (should he find one before another miner).
Why a miner will not choose ALL unconfirmed transactions (until reach the maximum block size)? What are the considerations when choosing transactions (other than the highest fee)?

Thanks.

If not, what do I need to run so I can be a part of the network and contribute to it?
