As I understand RBF should be enabled by default but it is not. All "category": "send" transactions show "bip125-replaceable": "no". I have put walletrbf=1 in bitcoin.conf file and restarted bitcoind but no change. Are there any changes in RBF functionality from previous versions I have missed?

Following latest round of sanctions even their biggest banks are now not able to transact internationally. North Korea is the only truly independent county. It is also independent from international banking oligopoly. They have nothing to lose. Introducing bitcoin as a settlement unit in their international economic relations is an exceptional opportunity for this country!

Is there any SQL or NoSQL db that is particularly suitable for bitcoin related projects? I mean things like specific data type for bitcoin addresses that will make address validation easier and app more secure in general. What was the reason behind to use Berkeley DB in Bitcoin Core client?

What's wrong with their margin trading fees?
They've started their margin trading with 0.05% rollover fees per day for both long and short positions. Today they informed me there are changes effective immediately. XBT/EUR rollover fee for maintaining a position is now 0.01% per 4 hours. Aside from the fact that fees are outrageously high, it is for the first time I see charging rollover fees per hour. Is rollover fees per hour a common practice among bitcoin exchanges? What's next - rollover fees per minute?

It may sound weird but that's the way it is!
Possible XT fork will have beneficial effect on current bitcoin price. If you buy bitcoins before the split, if it ever happens, will give you the opportunity to spend same coins twice both on Bitcoin and XT networks. So, if you buy 1 bitcoin now you actually buy 2 bitcoins if XT altcoin succeeds in being true and equal alternative to bitcoin!

Reference is made to RT's Google Hangout with Pirate Party Founder Rick Falkvinge and the question Stacy Herbert asked. http://rt.com/op-edge/internet-security-google-hangout-499/Very often people get confused while distinction is very simple in my view. Privacy is a right. It is one of the universal human rights. As with every right it is up to you to choose when you want to exercise this right and when not to. Anonymity is a tool/method to fight for your rights when they (incl. the right of privacy) are violated and not respected by the powers. |

Don't sell bitcoins if your only intention is to speculate on bitcoin exchange rate! Risk is too high for the next couple of years. In addition to that, if you're true bitcoin supporter, this will damage your positive attitude and your desire and ability to develop bitcoin related applications. Please don't sell, unless you know exactly what you do!

Obviously, they don't have enough bitcoins and are processing only partial refunds. They have speculated and sold large part of the bitcoins they got from their customers as "pre-orders". They were wrong expecting a lower bitcoin rate, however. This is why bicoin/$ exchange rate will now continue to rise as they need to buy bitcoins to make even partial refunds! PS The original title of this thread was: "WOW! BFL refuse full bitcoin refunds."However, using his moderator privileges gmaxwell decided to change it to match his own preferences. Go on, gmaxwell. Mock at other forum thread you don't like! To help you avoid partial bitcoin refunds by some ASIC startups, here is a short manual I've compiled for you: https://bitcointalk.org/index.php?topic=136615.0 |

We all must draw our conclusions from what has happened to bASIC "customers". I was quite active recently on this forum and I think I've spotted quite a large number of problems. Let me try to help you avoid future troubles following step by step considerations below:
1. There is nothing wrong with investing in ASIC startups as soon as you understand that you are investor, not customer!
2. There will be a lot of companies manufacturing ASICs, including bitcoin ASICs, by the end of 2013. It is just another question how successful their products will be and to what extend their specification will correspond to what was originally announced. Most of products will be complete failures.
3. Don't be greedy. Greed is the worst possible advisor of inexperienced investors.
4. Get rid of all your unprotected investments! Risk/reward ratio for unprotected investments is very unreasonable at this stage. Unprotected investments are all payments you made to an ASIC startup other than with a credit card not older than the 3 months chargeback window.
5. You should contact your credit card issuing bank and find out what is the maximum period of a payment you can request chargeback for! Be absolutely confident about that! About three months is the standard but your might be different.
6. You can get rid of an unprotected investment either by selling it or by requesting a refund from the ASIC startup company. I'm not aware of a third method.
7. Of all the unprotected investments the worst possible one is paying with bitcoins. I understand that this a bad advertisement for bitcoins but those are the merchants that refuse full bitcoin refunds that make it to appear that way! This should not be allowed by the bitcoin community if we want bitcoin to be addopted as a commercially viable currency!
8. ASIC startups strongly oppose full bitcoin refunds as they are a big profit source. Firstly, because bitcoin is still unregulated as a currency and as a method of payment and secondly, because receiving bitcoins and later refunding in $, gives those companies free option call to profit from BTC /$ exchange rates differences between payment and refund dates. Of course, what is profit for them is a loss for you!
9. If the chargeback window is about to close ask for a refund. If refund is not honored by the merchant within 48 hours then contact credit card issuer and request a chargeback!
10. If you successfully got your money back you might want consider paying for a pre-order again.
11. Don't be fooled by someone yelling at you that you'll lose your spot on the queue!
12. Maximum time loss might be couple of weeks. On the other hand, you can win big. If your ASIC is finally delivered you might find out that it does not match the announced specifications. If you are lucky you may have couple of month for finding such discrepancies and still be under the protection of chargeback window!
Good Luck

Chinese: 比特币
Hebrew: ביטקוין
Cyrillic: биткойн
Hindi, Marathi: बिटकॉइन
Arabic: بتكوين
Greek: μπίτκοϊν
Your input as addition or correction is highly appreciated.

On my end it appears the site is down for the last 2 days. http://www.bitcoinwatch.com/The following message is triggered irrespective of the browser used: Offline due to broken code. Recent changes in bitcoind are incompatible with our software and at the moment we don't have time to patch it. Do you see the same or it is just my ISP? |

Seems I have quite unusual problem.  I intend to help the bitcoin community and help it big but I have to convince the central bank that bitcoin is NOT money. What would be my best arguments? Thank you all for caring to respond. |

Bitcoin mining process consists of repeatedly increasing "nonce": payload = <some data related to things happening on the Bitcoin network>
nonce = 1
hash = SHA2( SHA2( payload + nonce ) ) It merely tries to find the right number. If SHA-2 is so secure then why have National Institute of Standards and Technology (NIST) announced an open competition for a new SHA-3 function to replace the older SHA-1 and SHA-2 after 2012? http://en.wikipedia.org/wiki/NIST_hash_function_competitionIs SHA-2 algorithm hard coded in the bitcoin protocol or not? Is it possible to upgraded it to SHA-3 after 2012? |

Current network hashrate is 103915 teraflop/s while a single super computer is able to make 8.2 petaflop/s. “It’s a very impressive machine,” Mr. Dongarra said. “It’s a lot more powerful than the other computers.”
The latest ranking of the top 500 computers, to be released Monday, is determined by running a standard mathematical equation. The winning computer was able to make 8.2 quadrillion calculations per second, or in more technical terms, 8.2 petaflops per second.
The performance of K is equivalent to linking around one million desktop computers, Mr. Dongarra said.

The transfer from another person can almost instantly be visible in your wallet, but it can take around 10 minutes until I can use it. So far so good. On FAQ page of one of the mining pools, however, you can read that transactions on the bitcoin network can take up to 120 blocks (20 hours) to be verified. Anyone willing to enlighten me how block chain of 120 blocks can be verified?

I believe I know what is a daemon in computing, but what is a headless daemon? Besides bitcoind what other examples of headless daemons that are both clients and daemons we have in mass use currently?
