So this is like all the addresses that exist? I wonder if anyone has found something and just kept quiet about it? This is pretty crazy.
that's what I wonder too... are there addresses with a balance? does this site snipe them before posting them?
they doesn't check or snipe any address because the address are not even stored in any database, they are generated in the server-side with a simple calculation when the page is loading.. it's On-The-Fly generated address. and yes, there are some addresses with balances but it's not easy to get it, you need to search in a billions of billions of Bitcoins Empty addresses.
i have collected a lot of informations about how Bitcoin work technically in my last research about the Cryptography and the Digital Currencies
