Title: Is it possible to know if an address is owned by blockchain.info? Post by: glub0x on June 19, 2017, 07:34:40 PM So, couple years ago i gave 0,5 btc to someone.
Now we have some trouble to access them. I belive he made an account on blockchain.info and gave me his public address. So here is my questions: -I have the public adress, Is it possible to verify that it is on blockchain.info so i don't waste my time to try to find his ID? -He only have one e-mail address. Was it possible before to register on blockchain.info without giving your e-mail? Blockchain's Id recovery doesn't send him his Id ... Thanks :) Title: Re: Is it possible to know if an address is owned by blockchain.info?

When you say public address are you talking about the Bitcoin address? If so, you can't get a ID/Email or even any info from the address itself.-He only have one e-mail address. Was it possible before to register on blockchain.info without giving your e-mail? Blockchain's Id recovery doesn't send him his Id ... I can't remember but if he doesn't have his ID and he can't recover with any email, then there is no way to find out his ID. Sorry =/The only thing you guys can do is try to find his ID in any PC/Email he had in the time he owned that wallet. Title: Re: Is it possible to know if an address is owned by blockchain.info?

When you say public address are you talking about the Bitcoin address? If so, you can't get a ID/Email or even any info from the address itself.Maybe there is a way for blockchain.info to say "yes this is the public address of a webwallet we have" this way it narrow our search... Now i realise that blockchain.info doesn't double check if your e-mail is valid. So i realise maybe he miss-spelled his e-mail address ...

Post by: ranochigo on June 20, 2017, 04:24:46 AM It is actually to deduce, up to a certain degree of certainty that the address belongs to a Blockchain.info wallet. Has he made any transactions from that address?
You have to get the a transaction ID that spends the coin from that address. Blockchain.info does have a feature which says where the transactions are first relayed by. This is mostly inaccurate but for their Blockchain wallet, the relayed by will be shown as Blockchain.info as opposed to a random IP address.

It is not always accurate but mostly it works for the big companies from bitcoin area. Title: Re: Is it possible to know if an address is owned by blockchain.info? Post by: glub0x on June 20, 2017, 09:41:06 AM Ok so i can't find anything!
I belive i sent him from my old mtgox account to this address 1YEnZd4y1LYXy8egBc3ZCsi2vpuPutQFa then he made a transaction to test bitcoin sending this address 129KL2hPChjcNKWvvZYUtmXgChhWPyZvSW and nothing happen... I belive this is a blockchain.info address but i am not sure. Title: Re: Is it possible to know if an address is owned by blockchain.info?

It only works because the addresses are sending funds to a known cold storage/hot wallet that is controlled by the said companies. Else, there is no way for them to identify where the address came from.It is not always accurate but mostly it works for the big companies from bitcoin area. 1YEnZd4y1LYXy8egBc3ZCsi2vpuPutQFa Doesn't look like a blockchain.info wallet address to me. Of course I can be wrong but I am almost certain about it. |
