even though it's mathematically improbable, i'm still tempted to try and generate tons of bitcoin wallets trying to duplicate a big wallet

What mechanism is there, if any, for handling wallet address collision?
-
address isn't what matters for this purpose, it's basically just a hash of a pubkey
-
if you could collide a privkey ("master"? idk much about bitcoin beyond "stuff on top of basic public key crypto")
-
then you could act just as the owner for all purposes (aside whatever other validation methods may exist again idk)
-
the important bit is the "if" is, colliding a 256-bit keyspace requires 2^128 computations
-
which is "all current computers working past heat death of the universe" type shit
-
the thing about powers of two is each addition to the exponent is a doubling
-
this sounds obvious but thing to stress is people don't have intuitions about this unless they work with it a lot

more feasible: looking for flawed (in concept or implementation) generation mechanisms, like that insanely dumb brainwallet thing

Thanks, this was very interesting. So if all processors currently mining had to switch to brute forcing collisions, would that make a dent?
Thanks. Twitter will use this to make your timeline better. UndoUndo
