Your identity may be private when you use Bitcoin, but an account̵7;s transactions are not. If you know someone’s Bitcoin address – the same number you use to send money to them – you can look up their transaction history and current account balance.
This is especially interesting when dealing with fraudsters. For example, in the massive Twitter hack on July 15, 2020, many news organizations and individuals reported how much money had been sent to the scammer’s Bitcoin address. This is how they discovered that number – and how you can do the same for all Bitcoin addresses.
To find this information, you need to research the Bitcoin blockchain. It is a public, shared register of all Bitcoin transactions that take place. The easiest way to access this information is through a website that makes the information available to you. We like Blockchain.com’s Blockchain Explorer for this.
Just visit the website, paste the Bitcoin address you want information about in the search field and press Enter. You can choose which currency you want
For example, Twitter attackers used the following address:
You see a list of transactions linked to that address.
As of the evening of July 15, the account had received 12.86 Bitcoin and sent 7.16 Bitcoin to other addresses.
To see how much money in US dollars, click on “USD” at the top right of the screen. (You can select another currency from the drop-down list to the right of the search bar.)
We can see that the account has received Bitcoin worth over $ 118,000,
Tools like this can also show you other details from the Bitcoin blockchain, including the current value of a Bitcoin account and transaction information. The information is out there, and you do not have to download the entire Bitcoin blockchain yourself to find it.
