When a sender is ready to send a cryptocurrency to the receiver’s wallet, they will be assigning the ownership of the cryptocurrency to the receiver’s wallet address. If the receiver needs to enjoy cryptocu-rrency ownership, then his private key should match the address to which the currency is assigned. Once it matches, cryptocurrency in the receiver’s wallet increases, whereas the cryptocurrency in the sen-der’s wallet decreases and vice-versa.

Here the ownership will be given with an encrypted message to the receiver’s wallet address in the form of a signature to have a secured transaction. There are two types of signature, and they are namely

•Signature:It is an encrypted form of the sender’s private keys to sign the tran-saction to be sent to the receiver’s wallet address. •Multi-Signature: It is an encrypted form of the sender’s private keys and the re-ceiver’s public key to sign the transaction to be sent to the recei-ver’s wallet.
