In the last few days, a record transaction was made on the Bitcoin blockchain that saw a whale move 101,857 BTC from one address to another.
It involved, at the current price, a little less than 1 billion dollars and the fee was only $0.49 dollars.
As we can see from the summary of the transaction, the fees per byte that have been paid amount to 13 satoshis and, thanks to the recent introduction of the privacy feature of the Blockchair block explorer, we discover that it has a value of 60 out of 100, hence not very secure.
It is therefore possible to start an identification process by tracing the various movements and understand who is behind it.
Who is the whale?
With the appropriate research, it is actually possible to trace who owns the wallet. It belongs to the company Xapo, a famous crypto asset custody platform.
As demonstrated, the privacy parameter shown by Blockchair correctly predicted that this transaction was not protected enough and allowed us to do a simple backward check to understand the identity of the wallet.
How to make a transaction private
It should be noted that the bitcoin blockchain is far from being a tool for money laundering or criminal or illegal activities of various kinds, because if very complex measures are not taken, then it is only a matter of time before discovering who owns a bitcoin address and identifying the person or company behind a transaction.
This is because, among other things, the Bitcoin blockchain is not anonymous but only pseudo-anonymous, contrary to what is often stated.
For more anonymous solutions it is possible to choose Zcash or Monero and/or use transaction mixers.
