Bitcoin receipts, also known as transaction records or confirmations, are created through the process of Bitcoin transactions. Here's a simplified explanation of how they are generated:

1. Initiating the Transaction: When someone wants to send Bitcoin to another party, they create a transaction using their wallet software. This transaction includes information such as the recipient's address and the amount being sent.

2. Signing the Transaction: The sender signs the transaction with their private key(s) to prove ownership and authorize the transfer. This ensures that only they have control over their funds.

3. Broadcasting to the Network: The signed transaction is then broadcasted by the sender's wallet software to other participants in the Bitcoin network—nodes and miners—via peer-to-peer communication protocols.

4. Verification and Inclusion in Blocks: Network nodes receive this broadcasted transaction and verify its validity by checking various factors like digital signatures, available funds, etc. Once verified, miners include it in a block—a group of transactions—with other pending transactions.

5. Confirmation on Blockchain: Miners compete to solve complex mathematical problems through mining processes for each block within specific time intervals (approximately 10 minutes). Once a miner successfully solves it, they add that block—with all included transactions—to the blockchain as an immutable record.

6. Availability of Receipts: With each new block added to the blockchain, including your confirmed transaction(s), multiple copies of these records exist across numerous nodes within decentralized network infrastructure accessible via explorers or APIs for anyone interested in viewing them—the bitcoin receipts we refer to earlier.

These steps outline how bitcoin receipts come into existence during regular Bitcoin transactions while leveraging consensus mechanisms among network participants like miners and nodes.

Is there a distinction between a signed and an unsigned transaction?

Absolutely, there is a significant distinction between a signed and an unsigned transaction in the context of Bitcoin.

1. Unsigned Transaction: An unsigned transaction is essentially a proposal or draft of a Bitcoin transaction. It contains all the necessary details such as sender and recipient addresses, amounts to be transferred, and any additional data required for the transaction. However, it lacks the crucial cryptographic signature that verifies the authenticity and authorizes the transfer.

2. Signed Transaction: A signed transaction is an approved version of a Bitcoin transaction that includes all necessary information along with digital signatures created using private keys associated with the sender's address(es). These digital signatures provide proof of ownership and ensure that only authorized parties can control their funds.

The signing process involves using mathematical algorithms to generate unique digital signatures tied to specific transactions. When these signatures are added to transactions, they become valid on the network and can be propagated across nodes for verification by miners before inclusion in blocks on the blockchain.

In summary, an unsigned transaction lacks cryptographic proof through digital signatures while signed transactions include these essential signatures generated by private keys—the key element enabling secure transfers within Bitcoin's decentralized system.

Do Transaction Hash/Id that have been confirmed means they have been digitally signed?
