 to the sender its related private key.

Neither the recipient nor the sender reveal their private keys in a transaction, because the private key authorizes transfer of the funds in that address to other users. Therefore, if a user loses his or her private key, the user may permanently lose access to the Bitcoin contained in the associated address. Likewise, Bitcoin is irretrievably lost if the private key associated with them is deleted and no backup has been made. When sending Bitcoin, a user’s Bitcoin Network software program must validate the transaction with the associated private key. The resulting digitally validated transaction is sent by the user’s Bitcoin Network software program to the Bitcoin Network to allow transaction confirmation.

Some Bitcoin transactions are conducted “off-blockchain” and are therefore not recorded in the Blockchain. These “off-blockchain transactions” involve the transfer of control over, or ownership of, a specific digital wallet holding Bitcoin or the reallocation of ownership of certain Bitcoin in a pooled-ownership digital wallet, such as a digital wallet owned by a Digital Asset Trading Platform. In contrast to on-blockchain transactions, which are publicly recorded on the Blockchain, information and data regarding off-blockchain transactions are generally not publicly available. Therefore, off-blockchain transactions are not truly Bitcoin transactions in that they do not involve the transfer of transaction data on the Bitcoin Network and do not reflect a movement of Bitcoin between addresses recorded in the Blockchain. For these reasons, off-blockchain transactions are subject to risks as any such transfer of Bitcoin ownership is not protected by the protocol behind the Bitcoin Network or recorded in, and validated through, the blockchain mechanism.

Summary of a Bitcoin Transaction 

In a Bitcoin transaction directly on the Bitcoin Network between two parties (as opposed to through an intermediary, such as a custodian), the following circumstances must initially be in place: (i) the party seeking to send Bitcoin must have a Bitcoin Network public key, and the Bitcoin Network must recognize that public key as having sufficient Bitcoin for the transaction; (ii) the receiving party must have a Bitcoin Network public key; and (iii) the spending party must have internet access with which to send its spending transaction.  

The receiving party must provide the spending party with its public key and allow the Blockchain to record the sending of Bitcoin to that public key. After the provision of a recipient’s Bitcoin Network public key, the spending party must enter the address into its Bitcoin Network software program along with the amount of Bitcoin to be sent. The amount of Bitcoin to be sent will typically be agreed upon between the two parties based on a
