I would like to do a Ukrainian translation.

Could you add the appropriate language file to the repo?

Shall we exchange answers (and reasoning) for 3, 4, and 13, and 14 to see which of us is mistaken?  Here are my hashes:


Hi Danny, good effort. I wont be putting any more time into it. Sorry that you lost it bc of my post about u's and v's.



Nicely done, mskwik.

Thanks for the research. Wanted to send 0.025 BTC but bitcoind says to your signature address:
Code:
<./bitcoind validateaddress 19VYu6KyJ56jegfYCqSWxgZDnSkHLb8gsv
>{
>   "isvalid" : false
>}


hmm, 9 transactions have been successfully processed to this address: http://blockchain.info/address/19VYu6KyJ56jegfYCqSWxgZDnSkHLb8gsv

edit: I think if you capitalize the last V it works:

19VYu6KyJ56jegfYCqSWxgZDnSkHLb8gsV


I don't know how that happened. thank you, btw!

On https://1broker.com/?c=about_privacy there are 7 occurrences of "Personal identification information." The conventional way to state this according to http://en.wikipedia.org/wiki/Personally_identifiable_information is in one of four ways:

Personally Identifiable Information
Personally Identifying Information
Personal Identifying Information
Personal Identifiable Information

For anyone else doing the Bible quiz, where are you getting the 1611 text? I've tried the following two:
http://www.kingjamesbibleonline.org/1611-Bible/
http://av1611.com/kjbp/kjv-bible-text/

However, the spellings are not quite the same between the two. Sometimes a "u" is written as a "v" and sometimes a "v" as a "u". Other times, they're the same. In one, a word might have an "e" appended to the end, in another version, there is no "e'. It would take too much effort to go through all possible combinations. What do you guys think is the "official" 1611 version?

Hi folks,
I've finally been let out of newbie "heaven".

I am interested in collaborating with others on this quiz (and obviously sharing the prize). If you PM me, I'll be more forthcoming about my answers, but here I will post the sha256 hash of my answers so far, so that we can compare. These are the answers to the Bible dig. I am using lowercase spellings for everything that I have. All answers contain only letters (even the one that asks for the number of horns). All answers are one-word, except for 12, for which I've included two possibilities.

Code:
1. fb613b14eef090eef0e73ae6f5948bf34d7974a0cd107125d55257273236f11b

   b605d13993abc3abf71d233cac374b641d3b2fb3162c3e2e7494a6a7ab24ce70 (from the second word, without the modifying noun)

15.36fc81e0b52fd7b92d4360ee156a5cb6e20ccf04fdb8dc832759fcc3cedc48aa


These hashes are just the sha256 hash of the answers. They can be computed in one of several ways:

1. On bitaddress.org, paste
Code:
javascript:alert(Crypto.SHA256('answer'));
into the address bar, substitute "answer" with your own word and hit enter. The popup will contain the hash.

2. In node.js use
Code:
crypto.createHash('sha256').update('answer').digest('hex')

3. On unix/linux type the following in the command line:
Code:
echo -n "answer" | shasum -a 256

For testing purposes, the sha256 of "answer" is 0db52f4076c082518412afd3dd3576e2cb0c63703fd7fed5e23ade60efef31d9

Re: How to regain anonymity for bitcoins after their owners have been revealed
by

I think you are confused.  How does knowing a single address let you know how many coins someone has?

For example say you were involved with someone who provided this (just one I grabbed randomly from blockchain.info) as his address.

http://blockchain.info/address/1BJQDc7c9k9GGiBfoqZmnigGvEuQZCsVGP

How many Bitcoins does this person have? 

My question is not really about the total bitcoin holdings of a particular user, but more about the balance of a particular address, and the flow of bitcoins in/out of this address. As I wrote earlier:

Quote from: 53rv3r
anonymity is lost forever for these particular bitcoins.

How to regain anonymity for bitcoins after their owners have been revealed
by

Hi all, I am aware that anonymity has been, and will continue to be, one of the most-discussed topics here. However, I couldn't find a good discussion about solutions to this problem:

Every time bitcoins are exchanged, clearly the two (or more) parties must know the addresses that are involved in the exchange. From that point on, these parties can track the flow of bitcoin using these addresses and will always know how much the others have and where their bitcoins go. Anonymity is lost forever for these particular bitcoins.

I understand that it's generally recommended to use many addresses, and the address specifications support a large number of addresses, so there is little concern of "running out." But if you make a large sale ( a house, or a car), you will eventually want to use these funds for yourself, and anonymity is not increased by spreading these funds around many addresses that you own. The other party will forever be able to know where these funds go.

Sure, not everyone cares about strong anonymity. However, if bitcoins gain widespread use, this non-anonymity can cause large problems for people, whether they care or not. Just the fact that others will know how much money I have is troubling; never mind that they can see where it goes.

Right now it's possible to use an exchange, convert to local currency, then purchase bitcoins to a new address again. But this method incurs fees, and is inconvenient, and, most importantly, is not feasible when/if bitcoins become the primary currency of the world (which I suspect they will). This method works well for small transactions, but is difficult for large sales.

Other than using mixing services, and the additional security risks that they present, are there other solutions to regaining anonymity for bitcoins after their owners have been revealed to each other? Is there any way to address this in the underlying protocols?

I know this must have been discussed before, and if someone can point to recent discussions, that would be useful, too.

bitcoin-analytics.com has been around for a while, and seems to have the most comprehensive amount of data. The free version is delayed by 6 hours, but there are three paid tiers (0.05 BTC per day, 0.3 BTC per month, 0.5 BTC for 2 months.)
