Understanding Bitcoin Transaction Outputs and Source Addresses

When sending cryptocurrencies such as Bitcoin (BTC), it is essential to understand the concepts of transaction outputs and source addresses. In this article, we will look at what happens when additional Bitcoin is sent to a source address after a specific transaction outcome has been set.

Transaction Outputs

In Bitcoin, each transaction includes multiple outputs, which are essentially “spends” or “amounts spent” to different recipients. A transaction output consists of the following components:

• Output Index: A unique identifier that identifies the output.

• Script Signature: A digital signature that verifies the authenticity and authorship of the outputs.

• Script

  : The actual code that makes up the output, which specifies how much of the output value is allocated to each recipient or address.

Source Addresses

A source address is a unique identifier used in Bitcoin transactions to specify where funds should be sent. When sending cryptocurrency from one wallet to another, it is common for multiple wallets to share the same source address. This allows users to consolidate their funds across different accounts without having to manually transfer them.

Additional BTC sent to source address

Let’s revisit our example with 3 addresses and a specific transaction output:

• Destination (source) address: 0.1yMvTbYf2P3B9G4J4C6c2X5VQDz7Uxg

• Initial transaction output:

+ Script signature: 304a01e56d00cfcbe8d5d078dd2e8c454b64a9df53f1ccf6f6bb35ef5f4caebd9

+ Script: 0x... (encrypted script code)

• Initial output value: 1 BTC

Additional BTC sent to source address

To send additional Bitcoin (2 BTC) to the destination address, you would:

• Open a new transaction output in your wallet.

• Set the output index to match the original output index.

• Add the script signature and the encrypted script code for that specific output.

In this example, 2 additional BTC would be allocated to the same source address (0.1yMvTbYf2P3B9G4J4C6c2X5VQDz7Uxg) without creating a new transaction or reusing an existing one.

Processing and Verification

When you create a transaction with additional Bitcoin sent to the source address, your wallet software needs to process and verify the transaction. The wallet will:

• Verify the script signature: Make sure the output was properly signed by the sender.

• Validate the script code: Verify that the encrypted script code is valid and matches the expected format.

• Update the transaction output values: Increase the output value for the destination address (0.1yMvTbYf2P3B9G4J4C6c2X5VQDz7Uxg).

Conclusion

In conclusion, when sending additional Bitcoin to a source address after setting a specific transaction outcome, it is essential to understand how your wallet software processes and verifies transactions. By following these steps, you can ensure that your cryptocurrency funds are properly allocated and consolidated across multiple wallets.
