You need to take an SHA256 hash of the 4 word pass phrase (upper and lower case characters have been used) and then use that in brainwallet.org as its pass phrase in order to get the private key (public address is https://blockchain.info/address/148cWMjpGsDtkVMNEb5oH8GU8yvSbgGbTK).

Initial clues are "wild" and "strain" (more will follow until the private key is revealed and if you discover the private key be sure to sweep the funds before posting it).

BTW - the first 8 characters of the SHA256 hash that you will need to use as the brainwallet pass phrase is 4c46256d - happy hunting!

You are welcome to ask questions and anything not as direct as "what is the pass phrase" will be answered to help with the guessing. Smiley

No questions yet so I'll expand on the clue "strain" - it has to do with nationality.

BTW - this is also a test of the safety of "brainwallets" so it is entirely possible that a bot *could* get the funds first (let's see).

Next clue is that the phrase is taken from a song (funds are still there so the bots haven't one yet).

It's old and quite famous (in the "strain" context).

Case sensitively could be the issue (hint second word starts with a lower case letter).

Reply sent - the "strain" clue is relevant here.

Hmm, this worked so well I didn't even check it fits all the clues

It's not a "Captain Obvious" song. Grin

(or perhaps it is - your guess was the first song that I sang publicly and won a prize for doing so)

Next clue is "state of origin" (that ties in with the "strain" clue and should narrow down your searching a lot).

Close but not exactly right - actually if someone has a large text file of song titles then that might really narrow things down with a regex so won't give more info on this now.

I will help out with an earlier clue though and say that a "strain" would understand "strine". Wink

Yay, I think I got it. I'm waiting for a block before I publish the answer. Didn't even need to use a bot Smiley. And I'm Canadian too. That must've been a lucky guess Tongue.

Well done!

Was it the last clue that helped out?

Yes, indeed. The nationality helped tremendously.

Edit: Transaction has been confirmed, so I'm publishing the answer.

The what: "The wild Colonial Boy", which hashes to 4c46256d89e3d5ce17d8ea5aff2b31852bc6d09d293e9c324658d914ead92fc9, which is the Brain Wallet passphrase.

The how: This is what I did to get the answer:

1. A "strain" would understand "strine". I didn't know what this meant, so I googled "strine". It's Aussie slang for Australian.
2. The remaining clue is "wild". So next, I google "wild Australian".
3. Nothing useful comes up, so I look at the remaining clues. "from a song"... so next I googled "wild Australian song".
4. First result was "The Wild Colonial Boy". Tried it, but didn't work. Looked back in the thread... "second word starts with a lower case letter"... Tried "The wild Colonial Boy", and it worked!

This is slightly abbreviated. There were a few detours I took during the sequence of events (the Australian national anthem, "Come along my hearties", etc.).

BTW I am guessing if the reward was a lot higher then someone might have actually created a bot just to crack it.

Even so by doing something unusual (here I just hashed so probably something a little more exotic would be preferable) - and of course not publishing that information - brainwallets can be made much more secure.
