This kind of address was really popular back then, I've seen people offering services to generate vanity address using split key method.

Not really popular now though because people just want to use bitcoin and generating random address is more efficient.

To be honest there is no anonymity over as someone could be tracked or traced through that address that is attached with their username. Before I was thinking it is that safe to use their username on the beginning of their wallet.
But people can do that even if you use a random address, though, especially if you publish it to the public. It depends on how someone manages their privacy properly in the end. CMIIW.

I remember making a few vanity addresses for a sign message or other things in the past. Looks really cool, just like how some onion addresses started with some easy-to-identify chars. But yeah, if it's long-term storage, you have to consider a lot of things, not just how cool your address sounds.

I have read a few things about vanity addresses before and I think the problem with vanity addresses lies in the fact that many people who try to generate it always try to trust third parties or pass through shortcuts to generate the address. For those who cannot go through the stress of generating the address offline or don't know the right sources to generate it, it will still be considered unsafe for them.
Yeah, but that's like saying bitcoin addresses are not safe because you can also let someone else do it for you. Tongue

I've used the split-key method mentioned above to generate addresses to someone on the Portuguese board. I couldn't steal his coins even if I wanted to.
Hmm, now I am learning something new. I have always assumed that it is automatically risky giving another person the chance to help you generate your address for you. With the split-key method, isn't there any chance the wallet can still be compromised if there is any error during generation or if handled by a hacker with advanced skills?

I am just wondering if there could be any possible loophole that still puts the address at risk or are you saying it is generally safe as long as the address was generated correctly and not through shortcuts like many people do?

Person I do not actually think it’s safe to actually use vanity address for large bitcoin storage or cold storage bitcoin, mostly because of enough entropy for seedphrase generation
I think you mean "entropy" here not "seedphrase" because there is no seed phrase in a vanity address generation process (it is not a deterministic wallet). They can be as secure as any regular address as long as the code you are using is secure.

Yeah it was a typo,

What they usually do is they start from a random entropy (just like you would when generating a regular random key) and then produce its corresponding address, if it contains the characters user wants, the code stops and prints the result. If not it increments the entropy and repeats the same thing. Incrementing the random entropy does not reduce its security.

I know that their is 128 bits of entropy for keys security and could be more (up to 256) or less, but this your explanation draws me a question is there possibility of that since we are starting from a random entropy that we could get an address with bits of entropy security less than the 128 bits which is the most consensus secured entropy or the randomness starts from that 128 bits and increments until the required address is generated and if it’s that then is there possibility of having higher bits of entropy say more than 256 bits and as we know bits higher than this is said to be much unnecessary in terms of security

Is this even possible?

I was playing around with ninjastic.space today and came across something that ive never thought to be possible until now.  Someone needs to explain to me how this person end up with a Bitcoin address that has it's username imprinted into the address itself.  I thought I know many things, I am just laughing myself because I know nothing.



Explain to me how Ffrankie has 1Frankiee in is Bitcoin address or there are Bitcoin wallet address that can do this? Don't tell me that this is coincidence.  

Imagine having this the ability to stick your username in your Bitcoin address  Cool Cool



Wow, i have been seeing such addresses and  little did i know that there is something called "vanity address".  OP i must say that your thread just add to my knowledge and i feel good knowing about the vanity address and also how its being generated randomly using the entropy seed phrase.

it still make sense to know that  it is as safe as the normal addresses that start with B1, 1c and....

You can create yours and the required resources are mentioned in this thread but it is not good for your privacy, never reuse your bitcoin addresses which keeps your privacy and also in future if quantum attack becomes possible, still your funds can be resistant to those attacks.

OP, I've read comments from other users who have posted here and I can see/say that you've already gotten your answer as to what such address is and how to get one for yourself, so I am not going to bother myself explaining anything again as doing this will simply be me repeating what others users have already..

But one I just want to let you know is that you are not alone in your being surprised, I too was super surprised the first day I got to find out about this same possibility, I created a thread about it just as you did now, and from the thread, I connected some a user here on the forum who helped me generate a bitcoin address with my own forum username as well, it's amazing to have (maybe good for showoff) but not important, I stopped using mine a long time ago due to lack of privacy..

Yeah vanitygen used to be big back in the day, now I am not sure why nobody uses it. Most likely because since segwit came out all addresses start with bc1. Also ETH has that ENS service so people just used that instead to get the exact address they want instead of having to search for hours for their desired string.

I remember there was a service which you used a split key and people would use their CPU to find you a vanity address using the split key method so your key was never actually exposed. I never used it because I never understood the mechanics behind it and always worried that there might be an exploit and get the private key leaked somehow.

It isn't a coincidence. This is achieved through vanity address generation, a space where one make use of special software to build a Bitcoin address that begins with chosen characters. It doesn't alter they way wallet operates; it only requires a lot of time to compute in order to find an address that has exact pattern you are looking. Names that appear simple yet demands strong guessing, though it is definitely possible. That's how an address can begin with anything like 1Frankiee.

There are vanitygen implementations for segwit... A quick google turned up: https://github.com/MakisChristou/vanitybech

Here's my bech32 vanity address (starts with m0ca, since "o" isn't an allowed character): bc1qm0cawdcdya3taqgqsww5wrvcydmh4xtzlmtkq6

There's even one that supports taproot: https://github.com/10gic/vanitygen-plusplus

Here's my taproot vanity address (start with m0cac): bc1pm0cac4uxjgm7ctc06sl9s7ka39nwcw3q84mehle7lah7a489n9psd873vj

Warning: i do not vouch for these vanitygen applications, they just appeared after a quick google DYOR
