How to know onwer of address???

[DannyElfman]

Exchanges are centralized, so a simple analysis could uncover who they are. Individuals who have only made a handful of transactions -- not so easy IMO.

And it is much harder if people create new addresses for each transaction.

Yes, but one must be careful not to share inputs from multiple addresses when sending, so as not to link those addresses.

[JerryCurlzzz]

Addresses can be linked anytime a centralized service / business with a brick and mortar presence is used.

I would like to know too,.

I don't think it's possible " the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. "

If you were running a full node and a TX that is broadcast by that address was broadcast directly to you node then you would know their IP address.

You won't know if the transaction is initiated by that IP, or is just relayed by that IP.
Also, people can push their transactions using sites like https://blockchain.info/pushtx and https://blockr.io/tx/push.

If you run a high enough of a percentage of the total nodes then it makes it easier to tell.

Light wallets make it more difficult to tell the originating IP address/node to most attackers.

i dont thing so, the whole point of bitcoin is annonimity, and creating a new address each time u use bitcoin.
the reason u know some of the addresses is that owners are not hiding , f.e. they have their info public.

The point IS NOT anonymity it is Pseudonymity, people can still see your transactions but it is hard to figure out who youre sending to and why.

It's usually impossible to find out the owner of the address (not exchanges, but regular addresses generated by average joes like me) unless they are posted online and linked to a profile or something, such as a forum.

Should be less likely, from the outset, Bitcoin advocates anonymity

[bitcoinforhelp]

there is no away to know owner, you can see some name beside it, but you can't be sure its the owner

Point of BTC is to keep annonymous, so all your efforts will payout low. Everyone should keep beeing annonymous and that's the way to spread btc network even further.

Didnt know that site. Thank you.

My question is that how someone can know who is the owner technically?

You don't, unless the owner claims the ownership of the address himself.

Or if you are even sending funds to another person (inter wallet transfer, transfer to a different wallet)

Some days ago, I knew block explorer site (http://chainz.cryptoid.info).

The site provides block explorer for 32 altcoins, but no bitcoin and popular altcoins like ltc, nmc, doge, etc...

no way to find who is the owner of the address unlesss you if the owner itself tell you that i am ..
