  P2WSH plays a crucial role in preventing transaction malleability in digital currencies. It is a type of transaction output script that requires the spender to provide a witness script that matches the script hash. This ensures that the transaction cannot be modified without invalidating the witness script, thus preventing malleability.

  Transaction malleability refers to the ability to modify the transaction ID without changing its validity. P2WSH addresses this issue by separating the witness data from the transaction ID, making it impossible to modify the transaction ID without invalidating the witness data. This enhances the security and integrity of digital currencies.

By separating the witness script from the transaction ID, P2WSH ensures that any modification to the transaction will result in an invalid witness script, preventing malleability attacks. This feature enhances the reliability and trustworthiness of digital currency transactions.
