Bitcoin (BTC) transactions are messages, such as emails, that are digitally signed using cryptography and sent out across the whole Bitcoin network to be verified. Bitcoin (BTC) users cannot divide a transaction into smaller amounts, and only the full output of the transaction may be spent. The difference between the input and output is a fee that miners collect to perform work (see Bitcoin mining vs. Coinbase transactions).
A coinbase transaction has no inputs, and one is created at every new block mined in the Bitcoin (BSV) network. A Bitcoin transaction is verified by a mining node and included in the transaction block, which is recorded in the Blockchain. A node is a miner connected to the Bitcoin(BSV) network, which finds blocks and processes transactions.
Mining is a process where new transactions between parties are verified and added to Bitcoins (BSV) public ledger, and it is the way that blockchains are secured. Bitcoin uses public-key cryptography to provide the integrity of transactions created on the network. With a unique public key and a digital signature, anyone on the Bitcoin network can validate and accept a Bitcoin transaction as valid, verifying that the person who transferred Bitcoins owned the Bitcoins at the time the transaction was made.
Using a private key associated with his or her Bitcoins, the user can sign transactions, thereby transferring the value to the new owner. Each owner transfers BitcoinA to the next, by digitally signing a hash of the previous transaction and the public key of the next owner, and adding them to the end of Bitcoin. Then, an example transaction is broadcasted to the rest of the network, where nodes check whether its private key can access inputs (by checking that Alice’s private key matches Alices’ claimed-owned public key).
The transaction is broadcast across the network, with each participant validating and broadcasting the transaction until it has reached nearly all the nodes on the network. A transaction must make its way onto the Bitcoin network for it to be propagated to a miner to be included in the public ledger (blockchain). Every time you make a transaction, sending or receiving Bitcoins from or to a Bitcoin wallet, this transaction is propagated on the blockchain.
In broader terms, transactions are placed on the blockchain by nodes as one party sends Bitcoin to another. To best illustrate how values are transferred on the network, we are going to go through an example transaction which Alice sends.05 Bitcoins to Bob. Alice Sends.05 Bitcoins to Bob.
Because the Bitcoin transaction is signed and contains no sensitive information, private keys, or credentials, it can be broadcast publicly using whatever basic networking medium is convenient. Once recorded in the blockchain and confirmed with enough later blocks, the transaction is permanently a part of Bitcoin’s public distributed ledger and is accepted by all participants as valid.
