==== Broadcasting Transactions to the Bitcoin Network
First, a transaction needs to be delivered to the bitcoin network so that it can be propagated and be included in the blockchain. In essence, a bitcoin transaction is just 300-400 bytes of data and has to reach any one of tens of thousands of bitcoin nodes. The sender does not need to trust the nodes they use to broadcast the transaction, as long as they use more than one to ensure that it propagates. The nodes don't need to trust the sender or establish the sender's "identity". Since the transaction is signed and contains no confidential information, private keys or credentials, it can be publicly broadcast using any underlying network transport that is convenient. Unlike credit card transactions, for example, which contain sensitive information and can only be transmitted on encrypted networks, a bitcoin transaction can be sent over any network. As long as the transaction can reach a bitcoin node that will propagate it into the bitcoin network, it doesn't matter how it is transported to the first node. Bitcoin transactions can therefore be transmitted to the bitcoin network over insecure networks such as Wifi, Bluetooth, NFC, Chirp, barcodes or by copying and pasting into a web form. In extreme cases, a bitcoin transaction could be transmitted over packet radio, satellite relay or shortwave using burst transmission, spread spectrum or frequency hoping to evade detection and jamming. A bitcoin transaction could even be encoded as smileys (emoticons) and posted in a public forum or sent as a text message or Skype chat message. Bitcoin has turned money into a data structure, making it virtually impossible to stop anyone from creating and executing a bitcoin transaction.
