Hey everyone, this got me thinking about something I recently read called the Dual Vanity Address Attack (DVAA). It’s where attackers can generate Bitcoin addresses that match patterns at both the start and end of an address. By doing this, they reduce the randomness we usually rely on for security, making it easier to pull off phishing or impersonation scams. It’s not quite brute-forcing keys, but it's another angle that shows how address generation can be vulnerable.
Hey everyone, this got me thinking about something I recently read called the Dual Vanity Address Attack (DVAA).
Dual Vanity Address Attack (DVAA) is not about brute-forcing private keys but rather reducing the address space that attackers need to search by matching both the prefix and suffix of Bitcoin addresses.
This drastically lowers the randomness, shrinking the area we rely on. As a result, it makes impersonation or phishing much easier. This method doesn’t replace brute-forcing I guess but complements it, further it shows one more weaknesses in address generation.
Please explain:
1) why you create a fresh new account to anonymously spread such crap and try to back it up without any technical explanation while maintaining to disguise your real and regularly username used on this forum
2) what exactly you have not understood about the avalanche effect and the result is that you assume you can use it to reduce the address range (which is not true)
3) why you bring randomness into play, that doesn't fit in with what you said, technically speaking in that context
Let's take your last username used "

two characters to look for...

4) please explain the reduction of keyspace on the shown example
