Decrypting Bitcoin Transactions: A Guide to Identifying Payments from Individuals

In the world of cryptocurrency, transactions are made under pseudonyms, so it is essential to verify who paid for a certain amount of bitcoin. While public keys and addresses can provide some clues, there are other ways to determine whether or not a person has paid. This way, you can distinguish between two different payment providers.

The Case of Public Keys

Bitcoin transactions include both a sender (S) and a receiver (R) address. If the amount matches, the sender address can be used as a key to identify the payer. For example:

• From: S = "bitcointalk"

• Receiver: R = "0x1234567890abcdef"

In this case, if you receive two payments with the same sender address (“S”) and receiver address (“R”), it is likely that both people are paying from the same wallet.

The Public Key Case (continued)

If the amount is different, public keys can be a valuable tool to determine who paid. For example:

• From: S = "bitcointalk"

• Receiver: R = "0x1234567890abcdef"

In this case, if you receive two payments with different sender addresses (“S”) but the same recipient address (“R”), it is likely that one person is sending money from their own wallet, and another person is receiving it on behalf of someone else.

More clues

While public keys can be a starting point for an investigation, there are other factors to consider:

• IP addresses: Bitcoin transactions are pseudonymous, but IP addresses can reveal the location of the sender. If you notice a consistent IP address for a particular wallet or account, it may indicate that the person is using a fake identity.

• Transaction Fees: Transaction fees can be related to who paid for a transaction. If you notice a significant difference in transaction fees between two payments from different individuals, it is possible that one person is using a cheaper service or paying inconsistently.

• Network Activity: Monitors network activity to detect unusual transactions, such as sudden spikes in IP address usage or irregularities in transaction amounts.

Conclusion

To successfully determine who paid for a Bitcoin transaction, you need to combine your understanding of Bitcoin transactions with additional methods, including:

• Public Key Analysis

• IP Address Analysis

• Transaction Fee Analysis

• Network Activity Monitoring

Using these methods, you can increase your chances of accurately determining who paid and who did not. Remember, no method is foolproof; a thorough investigation requires careful analysis and consideration of multiple factors.
