no upper/no lower address giveaway

[ryanc]

What?
Want an address that has no upper case letters (e.g. 184wwh1dtg8xv858d1n1ktj2cpvvbjugft) or no lower case letters (e.g. 1GNGTB96XPDHQ47Y6SNP8KN3YNPLFUP6B8)? I can do that - for free. I have some custom software that lets me do this a lot faster than vanitygen.

Is this safe?
Yes. I do split-key address generation, which prevents me from ever seeing your private key.

Instructions
These are based on ones provided by LoyceV and shorena.

1) Go to https://www.bitaddress.org/ move your mouse/type in the field until it shows 100%, then wait a few seconds. Optionally (but recommended), you can download the code, verify the signature, and run it offline.
2) Click "Vanity Wallet", then click the "generate" button to make a keypair.
3) Save your private key somewhere safe.
4) Reply to this thread with your public key, and whether you want "all letters uppercase" or "all letters lowercase". Addresses will still include numbers.
5) I'll reply with your "part private key".
6) Go back to the "Vanity Wallet" screen on https://www.bitaddress.org/.
7) Under Step 2, paste your private key in the first field and the part private key in the second, then click "Calculate Vanity Wallet".
8) Copy your "Vanity Private Key".
9) Click "Wallet Details", then paste your "Vanity Private Key" into the box and click "View Details". Your address will be under "Bitcoin Address Compressed" and your final private key under "Private Key WIF Compressed". Import it into your wallet.

Can I choose a prefix?
No. I may offer this for a fee in the future.

Why is this free?
I'd like to offer some high end address generation services, such as all upper case and all lower case letters (except the leading 1) in the future (please PM me if interested). Before I do that, I want to make sure there are no issues with the process.

Disclaimer
I may stop or change the terms of this giveaway at any time, and I reserve the right to refuse service to anyone for any reason. This service is offered without warranty of any kind.

I'll take an all uppercase address. Here is my step1 public key:

Code:

04E9FAC8DE731A020C6ED543F3ECB05858D4837C521EA216BD00751B605D77FD742D8CB833F57FAFA3C41E95766BC7614C4C04DBC89276117DDA3B8B74768CBD2D

Any idea roughly what it would cost for an all lowercase/uppercase letter address? I might be interested.


Edit: Any chance I could get an all uppercase & and all lowercase?

Thank you for this great offer to our community, I would take an all uppercase address, my public key generated is:

Per the free offer, these do have numbers sprinkled in:


PrivPart (WIF): KzhVUATVxF2F8tbEu9Czv11goAxu7JTRTdeN3W4zg4acsC8hzujT
Address (WIF):  1KT1C2KR3B5JP5GPL3MUEYN8RX8HWQ59L5

PrivPart (WIF): L3gJUkoM97hvbMX9Co7mouRQfjjMMwp6ebTsa2veUoEici94LP3s
Address (WIF):  1942t5fx93in6emv9ibdd4cz9xcnt4ewrk


Please note that the full private key for either address can be used to compute the private key for the other.

Any idea roughly what it would cost for an all lowercase/uppercase letter address? I might be interested.

Probably the BTC equivalent of $100-$200 for all uppercase except for the leading 1 and $300-$500 for all lowercase except for the leading 1. Those prices are estimates based on testing I did (which is where my donation address came from), I would need to actually do the math on my costs before taking orders.

Thank you, sorry If i sound like a noob but I am getting another address, I pasted the private key in the first field and in the second field the part PrivPart generated from you.
Vanity Bitcoin Address: 1LJ4mCnxas7SZUfSLVQYprpeE6FAfxLxJP, there is something wrong but I can't find where.

The Vanity Wallet tool generates "uncompressed" addresses, but I'm finding "compressed" addresses because it's a little faster and they result in smaller transactions with lower fees. You have to convert to compressed format using steps 8 and 9.

Thank you very much, this generates a private key which I did paste in 'wallet details' page.
Now I have 2 addresses, right? One compressed and one uncompressed (both of them look valid in blockchain search)
I tried signing a message with both of them and works, thanks.

I went through all the steps and got my address imported. Still looks like a typical address until you look closely, wish there were less numbers
Thank you and good luck with your business.

hm... both types are cool but I would prefer uppercase

is it possible to buy all lowercase, too? If yes how much?

[ImHash]

So you are taking from $200 up to $500 just for an address including no numbers except the 1 at the beginning? then we must do a large transaction for it to worth the money lol. I want an address with prefix ImHash and will get it from loyce for free.

Here you go. Please be aware if you use both of these addresses, the private key for one can be computed from the other. I don't recommend importing them into different wallets.

Some people like such things. If you don't, that's fine by me.

That kind of address takes a lot of processing power to generate, so you'd have to pay for that. I'm not quite ready to do that yet, but when I am it will be several hundred dollars worth of BTC. If you're interested, I can PM you when I'm ready.

I guess I will satisfy myself with an uppercase address then. No need if you are trying to make it ready just that I had requested. Anyway curious about the software you developed. Also mind telling me what is the difficulty of such addresses ( I mean one you are doing it right now) and power you are having.

The difficulty for all lowercase, no numbers except for the leading 1 is about 1.16x10¹³, and for all uppercase, no numbers except for the leading 1 is about 2.81x10¹². I do the computation on AWS. The software is based on libsecp256k1. The free addresses will all have numbers mixed in.

I am not sure what the difficulty is for the addresses with numbers mixed in, but it generally takes me under a minute to create those.
