Well, I was bumping this every month. At the end of +3 months from receipt, now. This will probably be the my last bump ever, as I now have (also linked in the OP) the White Paper discussion here: https://bitcointalksearch.org/topic/white-paper-receipt-of-btc-from-unknown-person-155112

Ok, I'm locking this topic until there is proof of ownership, significant news, or technical/legal questions or answers PMed or otherwise communicated to me (I'm not hard to get a hold of). The "it was mine" bit wasn't even funny the first time. You will still be able to delete your douchebaggery posts, through the thread lock.

it was mine, lost it somehow, silly me

please send 500 BTC to 17ws1xeoufHkKJdBR71p6kfHiTz5qqPGbH

keep the rest as finders reward

thx!

sad part: this idiot was serious...

I'd like to offer a better option
Send 400 BTC to 1JSTuR14XLBSDKzUxjiwkXguLPyW8mqkWQ
and you can keep the rest as a reward.

Actually, if you send 450BTC to me, you can keep the rest. If the owner comes back, I'll pay for 50BTC out of my pocket.

Once who ever sent the funds to 1TBZjmXho6mdGhoESaMV2svtqJXYtWfEp realizes they messed up I expect that they would google the address, as it's in your profile it brings up some of your posts ie: https://bitcointalksearch.org/topic/why-not-direct-trade-with-dwolla-129037 where they would be able to see who to PM, but this current thread doesn't show up or isn't prominent in search as yet but may become more so if you added the address to the thread title, eg: Re: Random sweeps into my public wallet 1TBZjmXho6mdGhoESaMV2svtqJXYtWfEp totaling 519.704 - Lost and Found?

If they search the forum for 1TBZjmXho6mdGhoESaMV2svtqJXYtWfEp though then this thread is the first hit already here. We should make side bets on when they will find out what they've done & the total they'll have sent by then - I'll guess the 28th Dec after sending another 500 coins to it.

Putting the address in the title probably ought to help with search. I imagine anyone moving that kind of btc with any regularity would at least know of this forum to search for it. The OP's concern about this being a portion of some ill-gotten sum might have some merit though. Given the way that Mt Gox has flagged some coins before that might have been connected to Bitcoinica, a party might attempt running the coins through a lossy mixing that sacrifices some coins to addresses known to be in use. I don't know how plausible spreading the taint could be as a serious laundering strategy, but it is something is probably only possible with bitcoin.

Thanks for the analysis molecular - that's exactly the path I was going down. I've worked on a project that specially seeded a SecureRandom (with other random input) to init the cryptographic functions, but bitcoinj does not appear to provide a direct way to provide the randomness, so it falls to the underlying library. Since that's the BouncyCastle/SpongyCastle crypto lib, I'm confident it is performed as well as reasonably possible.

my bet: Jan 2nd, no more coins will be sent.

The implementation of SecureRandom is probably platform-dependant. Do we know the jvm/platform used to generate 1BTZ?

if it was a collision, win for sure Wink

Not for sure. It's still possible there are some java runtimes out there that have insecure implementations of SecureRandom.

maybe some old ass java.

nope, TheButterZone PMed me his version info. It's not "old ass". (edited my previous post accordingly).

Also see my post before this one for more info on SecureRandom

The file which controls the configuration of the SecureRandom API is located at: $JAVA_HOME/lib/security/java.security

TheButterZone, can you try to locate that file?

In my installation it contains a line:

Code:

securerandom.source=file:/dev/urandom

specifying the underlying system source of random.

It'd be interesting to know how your source for SecureRandom is configured.

I looked at VanityAddress.jar:

Random Key is generated in class VanityAddr using com.google.bitcoin.core.ECKey.

Code:

import com.google.bitcoin.core.ECKey;
...
key = new ECKey();

ECKey constructor is implemented as:

Code:

import java.security.SecureRandom;
...
private static final SecureRandom secureRandom = new [b]SecureRandom()[/b];
...
public ECKey()
  {
    ECKeyPairGenerator generator = new ECKeyPairGenerator();
    ECKeyGenerationParameters keygenParams = new ECKeyGenerationParameters(ecParams, secureRandom);
    generator.init(keygenParams);
    AsymmetricCipherKeyPair keypair = generator.generateKeyPair();
    ECPrivateKeyParameters privParams = (ECPrivateKeyParameters)keypair.getPrivate();
    ECPublicKeyParameters pubParams = (ECPublicKeyParameters)keypair.getPublic();
    this.priv = privParams.getD();

    this.pub = pubParams.getQ().getEncoded();
    this.creationTimeSeconds = (Utils.now().getTime() / 1000L);
  }

So the random number generator used was: java.security.SecureRandom.

Quote from: http://docs.oracle.com/javase/6/docs/api/java/security/SecureRandom.html

This class provides a cryptographically strong random number generator (RNG).

A cryptographically strong random number minimally complies with the statistical random number generator tests specified in FIPS 140-2, Security Requirements for Cryptographic Modules, section 4.9.1. Additionally, SecureRandom must produce non-deterministic output. Therefore any seed material passed to a SecureRandom object must be unpredictable, and all SecureRandom output sequences must be cryptographically strong, as described in RFC 1750: Randomness Recommendations for Security.

EDIT: TheButterZone pmed me his java runtime info. Nothing obscure, so it should use a "good" implementation of SecureRandom.

I suggest a donation to [url]http://www.videoneat.com/]http://www.videoneat.com/][url]http://www.videoneat.com/[/url] !

They just came up to accept BTC donation because I've suggested them to do so. They did'nt knew about BTC before !

This site is quite good.

It host Lectures and Documentary. The site was built by 2 people. 2 people who have spent thousands of hours of work on it over the period of 8 months. This is related to TROM (The Reality Of Me), a must see !

2 peoples have invest all their time and economy into this effort, for at least 8 month. They are now completely broke. If this came to a lost, it would be such a waste Sad

I urge anyone reading this to donate some BTC. If anyone reading gives 1% (or more, or less) of their BTC, they will see the number of donator, and will have some more time to keep it on !

I hope you will take a look at it, and will donate some.

Thanks for your time, and please, at least, give some time to look at their awesome work !

Have a nice life !

.. Are you videoneat?
