Any others?


(*) I will only consider addresses that have an actual owner, not things like:

12345678googr7AWKah5kpLnx2h8zDS6NK      (11-char vanity address??)   

7 char vanity address. The "goog" is almost certainly just a coincidence. I can see someone wanting an address starting with 12345678, but why would they go for 12345678goog? There's no way it was deliberate.

1111111111111111111114oLvT2             (21 ones in a row, weird length)

Not a real address, it is literally just the number 0 encoded as a bitcoin address. It's nice that someone's sent some coins to it, though. If those coins ever go anywhere, it'll constitute absolute proof that the whole system is completely broken and we're all doomed.

See Sig?

1MrPonzi - I wasted enough luck on that one... Been screwed ever since...

[casascius]

My Casascius Coins website issued a payment address starting with"1Fake" and the customer did not know if he got a real or a test address. Suspicious, he redid his order and paid the new (non-1Fake) address he was issued, then wrote to tell me about it.  The 1Fake address was a real address and a genuine coincidence.

I am starting a list of the most bizarre / improbable addresses found in the blockchain.  
 

Any particular address you listed as as probable as any other one. The bizarreness is in our heads.

This: validateaddress 1111111111111111111114oLvT2
Returns true

It's valid but can't be used?

I think he ment if someone "found" the private key then Bitcoin is doomed as that could possibly conclude that sha256 mechinism is flawed which in turn means the banks are teh sucks and Bitcoin two!

Wow This might be a reason to consider a new feature for future Bitcoin clients: the user could optionally provide a wordlist and the client should make sure that newly generated addresses contain none of the words in that list (something like an inverse vanitygen). Such a list might include only some potentially offensive/confusing terms or even be a whole dictionary to go for sure (cost of checking is negligible due to the low risk of accidental matches). In a professional environment such a feature could be quite useful (you don't want to accidentally present your customer with a payment address like 1UAss or something )

This corresponds to a public key hash of    0000000000000000000000000000000000000000

This is likely a bug in an experimental client or pool.

It can't be used. If it could, bitcoin would be broken.

So who was so ingenious to send 2 btc to that address?

I own the first one (it's in my sig).  It's actually not too crazy for a GPU to produce, but you need regex which isn't supported by GPU-vanitygen.  So, I sent a few of my my idling CPUs (on my mining machines) on that task and found it in a couple weeks.  I think I figured out it should've been like 70 days on average, so I definitely got lucky!  I'm not sure it was really worth all the energy I could've spent trying to find it, but it's not like my CPUs were doing anything useful anyway, and my PSUs are adequately overpowered for the GPU load...

The only problem with the address is that it's so strange that many people don't even recognize it as a real address.  It's disappointing to get messages like "What is 1QBD?".

Here's another one starting with 11 digits. I can't remember seeing such a long digit-only prefix before.

[Edit] Found a longer one in the meantime

[Otoh]

The longest to date generated by ThePiachu's Vanity Pool & thread btw is 9 chars after the initial 1 for 1ELiZABETHdzGTuQeg2RnCcWBMVo3ySfTz that I'd requested as a gift for someone.

Nice! Adding it to the list.
