PSBT allows multiple participants to sign transactions without revealing their private keys. This enhances the security and reliability of transactions, while also addressing privacy issues to a certain extent.\n\nThe main advantage of PSBT is its offline signature capability. Offline signing means that participants can sign transactions without directly handling Bitcoin assets. This signing method reduces the risks involved in the transaction process because it avoids exposing private keys directly during the transaction. With PSBT, participants can submit signed transactions to the blockchain."}]}],"pr":"9e4789a8665165cfb3a3156f6a26ac84a4a76a8a9c86d73184871e6ea232c04e"}
