From Grok :
A Bitcoin PayJoin, also known as a CoinJoin or P2EP (Pay-to-End-Point), is a type of transaction that enhances the privacy of Bitcoin users. Here's how it works:

Privacy Enhancement: In a standard Bitcoin transaction, the inputs (where the coins are coming from) are explicitly linked to the outputs (where the coins are going). PayJoin disrupts this direct link by combining the inputs from multiple parties into one transaction, making it harder for outside observers to determine who paid whom.

Transaction Structure: In a PayJoin, both the payer and the payee contribute inputs to the transaction. For instance, if Alice wants to pay Bob, instead of just Alice sending coins to Bob, both Alice and Bob might include their own coins in the transaction. The transaction then sends the payment to Bob and might also return change to both parties.

Advantages Over Traditional CoinJoin:

Less Obvious: Traditional CoinJoins are often identifiable because they typically combine inputs from many users into one large transaction with multiple outputs. PayJoins can look like normal transactions since they might only involve two parties.

Reduced Fees: Since it can be structured with fewer inputs and outputs than a traditional CoinJoin, transaction fees might be lower.

Better Privacy: By mixing funds directly in payment transactions, it adds an extra layer of obscurity, making it more difficult to trace the flow of coins back to their original source.

Implementation: PayJoin requires coordination between the payer and payee, which can be facilitated through specialized software or protocols. This coordination means both parties must agree to participate in a PayJoin, making it less anonymous but more private than regular transactions.

Compliance and Legal Considerations: While PayJoin increases privacy, it's important for users to understand that in some jurisdictions, enhancing privacy might raise legal or compliance issues, especially if it's used to obscure the source of funds for illegal activities.

Support: Not all wallets or services support PayJoin, so users need to use compatible software or services. Notable implementations include features in wallets like JoinMarket or plugins for wallets like Sparrow Wallet.

By using PayJoin, Bitcoin users can maintain better privacy without necessarily relying on large-scale mixing services, which might be more noticeable and potentially more risky from both a privacy and regulatory perspective.
