Transmitting the transaction
Once the asset transfer information has been signed by the user, other information, such as the user's public key for verification, the destination public address, and other information that is necessary for verification, is provided. This information is broadcast to all the nodes so that it can be included in the blockchain:
Figure 3.4: Information in a transaction
As shown in the preceding Figure 3.4, Alice will include information such as her public key and Bob's address in the transaction. The information provided in the transaction should suffice for Bob to claim that the asset belongs to him once the transaction has been included in any of the blocks in the blockchain.
The public address of the node acts as an identifier for the node and is constructed from the public key by performing hashing and encoding. Chapter 5, Cryptocurrency, will cover this in detail.
