[CLAIMED!] Bounty: 0.25 BTC. Find the Bitcoins hidden in plain sight.

[mmdough]

"This string contains 0.25 BTC hiding in plain sight."

Which string?

The encapsulated one.

That's implied but not stated.

I doubt it's a trick question... but go off on that tangent if you want. 

That's my MO. I start with the liar's paradox as an axiom and go from there.

It makes politics more interesting, I'll tell you that.

They're in plain sight.


He told us where they were.


Yet they're hidden behind the address.


and he pointed out that he already sent them so he wouldn't be able to say they weren't there yet.

[casascius]

When they are "found" in the proper sense of the word, you should see them spent on the block explorer into the winner's wallet.  This spend will have been done by the winner, not by me.

[GeniuSxBoY]

...

[mmdough]

If you find it you will be able to send it to yourself.

Implies that unless you can get at that address, you haven't found 'em yet.

It's not a riddle in the sense that he wants you to answer-- it's a race to grab the coins.

BUT HOW

[AtlasONo]

Plain site is an e-wallet

[SgtSpike]

I bet the SHA-256 of that message is the private key needed to claim the bounty.

Doesn't look like a private key to me...

47510706d76bc74a5d57bdcffc68c9bbbc2d496bef87c91de7f616129ac62b5f

Lots of 5's in there though... maybe it starts at a midpoint and goes to whatever characters are necessary for a private key?

Every 256-bit value is a valid private key.

I tried importing it, and the python script I am using says "Bad private key".

[AtlasONo]

I know what it is but i don't know the specifics of what I have o do

[mmdough]

I'll bet you anything the e-wallet is a spruce code somewhere.

Well, I'll bet you .25 BTC that it is.

No, wait, I won't.

Your scripts expects the key to be encapsulated in an X.509 DER object, including the particular type of key it is and so on. It was not designed to import the raw private key data.

[cuddlefish]

protip: It's a deterministic wallet, we have our seed here, now figure out the PRNG

or it may be an encoded private key, sha256, so single-seed no nonce.

[gentakin]

Your scripts expects the key to be encapsulated in an X.509 DER object, including the particular type of key it is and so on. It was not designed to import the raw private key data.

Code:

$ ./pywallet.py 
A mandatory option is missing

Usage: pywallet.py [options]
[..]
  --importprivkey=KEY  import private key from vanitygen

(vanitygen seems to output base58-encoded privkeys)

Code:

$ ./pywallet.py --importprivkey=9MYaow1fLJHwaYgZVs6fLeALpTWuZY4zTA2NfFz8eMNQAiGQmzqeaHAYstXQ81vgVc
Bad private key

So I probably got the hash wrong. I used an online sha256 tool, copied that sentence into the form field, got the hash in base64, then converted base64 to hex using another online tool, then used a copy-pasted python script to create this base58 key. It was worth a try.

[julz]

I think I'm gonna have to give up.  I can't find a website that imports private keys - and bitcoind crashes on my one working linux box.

Someone try importing TssgcsBChginpnst

Just a guess!

[BitcoinPorn]

I need the programs and intelligence from this thread http://forum.bitcoin.org/index.php?topic=23081.0

Someone read that and got splitsies with me when you get it.

[mmdough]

How does one import a private key anyway? Do I need a new version of the client? I have an old one, I believe.

Bitchin, thanks

edit: Looking at it now, it doesn't do what I wanted... actually at all. But thanks anyway, it's neat.

[julz]

I'm pretty sure some of you are overcomplicating the key import process.

If it's hidden in 'plain sight' - you probably don't need to hash it etc and use python or shell scripts.

Just work out which letters to read off  e.g 1st and last letter of each word?

And follow the instructions on bitbills to import.

The impossible part for me is running a bitcoind that has the 'importprivkey' command.
The paper wallet thing looks interesting.. once the gui allows key import.

[casascius]

You guys are on the right track.  It is likely to be found soon.

This is not a valid Base58-encoded wallet import string.  Valid Base58-encoded wallet import strings always start with '5'.
