Edit: No longer offering service due to lack of interest. Thank you.
I'm offering bitcoin vanity addresses (bitcoin addresses that begin with a chosen prefix, e.g. 1BitcoiN
If you choose the split-key method, please send me the public key generated by private message or post it here. It's safe to post these.
You can generate a public key part at http://bitaddress.org
with your chosen prefix, keep your part-private-key safe somewhere, post or message your prefix, then I get to work on generating the partial private key which completes the vanity wallet address generation. This ensures you do not have to trust me at all, since I will never see your private key.
Example: visit bitaddress.org, navigate to vanity wallet, and click generate. You have a public key and a part private key. Keep the part private key safe. Below these generated keys, at Step 2, once I have generated the vanity address and give the part private key, you would enter your private part of the key, then the private key part that I generate. When this is successful, your vanity address is presented with chosen prefix and public and private keys. The private key you can import directly into Bitcoin Core, Bitcoin Classic, Bitcoin XT.
I'm offering prefixes of length up to 7 valid characters (case sensitive or case insensitive) in the ordinary case (asking 0.005 BTC), others by agreement and a small bitcoin deposit which helps cover the cost of my compute resources.
The bitcoin price of a good vanity address you might want depends on whether you think it's worth anything and the estimate time length of computing the address. For most 7-char prefixes, I think 0.005 BTC is fair. I can generate most valid prefixes of that length over night on a machine with 16 Xeon cores.
Thanks, questions or comments welcome.
