Bitcoin Forum

Hi, guys.

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

It has unique feature that we can know who is the owner of an address, for example mintpal, cryptsy, or poloniex.

As I think, it is very thankful feature, but not all coins are designated.

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

Is there any special way to recognize the owner?

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.

its not possible that you can know about owner of address because bitcoin is all about anonymity

The only way to know the owner info if he buy something with btc and have a shipment address. Otherwise its hard to tell if its real.

If address owner is not selling any thing then how can do this  :)

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. "

its impossible, either people post the info (which might be fake) or delivery address.

I am assuming that the seller would have to put your info out there? I would not want that to happen and would never buy from the guy again if that was the case.

Unless the address owner discloses it publicly or use the address to handle payments repeatedly, there is no way you can get the address owner's identity.

You can only work out the name after the address has been used and linked with a service or something, otherwise its impossible to know who owns the address.

You can not know who is the owner of an address, that's impossible !

Only things that you can do, is to see if that address is much utilized. :)

The onus of protecting the pseudonymous nature of an address is on its owner.
It can only be revealed if the owner does so voluntarily or isn't careful about his usage patterns.

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.

If the person wasn't running a client but withdrew from an exchange or gambling sites or online wallets, you will only know their IP.The worst case is that the person ran their bitcoin client behind Tor.

This site does not work. I tried to find out the owner of Satoshi's address 12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX, but it could not say that it is Satoshi. :D

Nope, not possible at all, unless it's linked to someone. I normally Google addresses, or use the Deep Net search engine if I want to see if it's linked.

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.

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. :)

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

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.

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

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.

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)

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 .. :)
