The chance to hit a address in use is about:

1.34*10^-43 %

0.000,000,000,000,000,000,000,000,000,000,000,000,000,013,4 %

So there is a chance? Grin

LOL

BTW nobody answered my question:

How does one actually SAY this : 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976

http://en.wikipedia.org/wiki/Names_of_large_numbers

Start from there to: find the largest number and then start going down.

There are currently around 200.000 adresses in use:

https://blockchain.info/de/charts/n-unique-addresses

with a total of 2^160 is 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 possbile addresses.

soooooooooooooooooo Cheesy

pretty small number, huh ;-)

How many addresses does need to be generated to have 50% change for one clash?

I assume this is same problem as birthday paradox, just with very large numbers?

Avram's law: As the length of a BitcoinTalk thread increases, the probability of a quantum computer being mentioned approaches 1.

OK, your point being?

My point is that as the length of a BitcoinTalk thread increases, the probability of a quantum computer being mentioned approaches 1.

For sure it does.
Even though Quantums right now cannot crack SHA-256 it still remains a thread.
Don't you think?

Would it be possible for someone to write a malicious program to generate a massive amount of addresses continously?

I am thinking of a large botnet, all generating thousands of addresses a second?

Good question.

What about Quantums.
Can they not generate thousands of addresses per second?

That could also be an attack on the network (of some sort).

'The right to privacy matters'

All very interesting but here is a question how many addresses can be generated in a day one 1 fast pc?

1 per second seems easy with a code written for it.

Lets say I want to possess all the address not used. 1 per second comes to 86,400 a day or 31,536,000 a year.

I also say lets use a factor of 10 which means 315,360,000 a year lets say everyone on the planet does that.

10,000,000,000 is more then our real count of people but WTF makes the math easy.

315,360,000 x 10,000,000,000 = 3,153,600,000,000,000,000 in one year while a big number it is no where near the amount possible.

3,153,600,000,000,000,000 is a lot smaller then 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976

So even if people try to 'corner' the BTC address market it would take a long time to do so.

And addresses could be increased in length if really needed to do so.

How does one even say this number: 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 Huh

I bet it would be a whole paragraph Grin

you will win many time at loto games before you run out of addresses.

The max amount of Bitcoin Addresses is more or less equal to the number of atoms that are in this world..

It's Money 2.0| It’s gold for nerds | It's Bitcoin

When you create an address nothing happens to the network. Only when payment is sent to that address is when the network will have a record of that address.

It would be possible, in theory (but extremely unlikely) for two people to "create" an address but neither send any BTC to it so neither would ever know that the other had created such address.

This does actually happen with brain wallet miners as they are "mining" the same kind of potential brain wallets.

Long after man has fallen, future civilizations, possibly evolved from mice or cockroaches will still be generating Bitcoin addresses.

There are this many addresses

1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976

Is that actually how many there are or did you pull that out of your behind?
If that's the number... wow.

That's the actual number (assuming that all possible 160 bit values will result from a SHA-256 hash followed by a RIPEMD-160 hash of all possible 256 bit ECDSA public keys using the Secp256k1 curve).
