If you have used Bitcoin, you would know that the owner’s true identity is not disclosed. Anonymity is maintained in Bitcoin or other cryptocurrency transactions through private key codes and addresses. The owner of Bitcoin has to undergo a KYC procedure, but they are given an anonymous code generated to maintain the secrecy of any online transaction. The person will make the payment through that code and move further on the blockchain.
At this point, the owner can be tracked through the payment chain. But, as soon as the payment is made, the provided code is burned, and again the anonymity continues. This public display of the blockchain movement prevents double-spending and illegal transactions. However, your true identity and location are concealed throughout the process, and thus, anonymity is maintained.
