Is it possible to identify the sender of bitcoins on the blockchain

It is possible to identify the sender of bitcoins on the blockchain to some extent. Every bitcoin transaction is recorded on the blockchain, and each transaction has a unique identifier. By using a blockchain explorer, it is possible to view all of the blocks on the blockchain and see the addresses and transactions related to them, as well as the addresses that it has been sent to. This means that if a person knows the address of a bitcoin wallet, they can see all of the transactions that have been made to and from that wallet.

However, it is important to note that while the transactions on the blockchain are transparent, the identities of the people behind the transactions are not. This is because bitcoin transactions are pseudonymous, meaning that they are not directly linked to a person's real-world identity. Instead, each bitcoin address is associated with a public key, which is a string of alphanumeric characters. The private key, which is used to sign and authorize transactions, is kept secret by the owner of the wallet.

In summary, while it is possible to see the transactions on the blockchain and the addresses associated with them, it is not possible to directly identify the sender of bitcoins without additional information. The blockchain provides a transparent record of all transactions, but the anonymity of the users is preserved through the use of pseudonymous addresses.
