There have been ongoing discussions and debates within the Bitcoin community regarding the necessity of filtering unconfirmed transactions. One of the main points of contention is the trade-off between privacy and transaction notification in Bitcoin wallets.The current method of filtering unconfirmed transactions, known as BIP37, has been criticized for its resource consumption and lack of long-term value for Bitcoin. Some argue that relying solely on BIP37 availability is fragile and exploring alternative methods is reasonable.In a discussion thread on the bitcoin-dev forum, it was suggested that users may be willing to sacrifice privacy by using client-side filtering in exchange for not having an "incoming transaction" feature or fetching all received transactions only when they need 0-conf. However, others argue that immediate feedback on transactions being broadcasted is necessary for basic usability.It has been noted that there are privacy issues associated with BIP37, but they are not a significant concern for most regular users. On the other hand, delayed or missing transactions are a much more common issue faced by Bitcoin wallet users.The concept of Simplified Payment Verification (SPV) was brought up in the discussion, with the reminder that it is not applicable to unconfirmed transactions. SPV relies on miners committing to a transaction through work to provide assurance to the user that the transaction is valid. However, unconfirmed transactions can be easily forged by anyone, including the user's ISP.The debate also touched on the use of mempool filtering, which gives users false assurance that there is a valid but yet-to-be-confirmed transaction sending them money. It was pointed out that unconfirmed transactions are not final and can still be rejected by the network.In addition to the discussion on filtering unconfirmed transactions, there have been proposals for new light client Bitcoin Improvement Proposals (BIPs) that aim to improve the usability and efficiency of Bitcoin wallets. These proposals include suggestions for different types of light clients and potential solutions to address issues in the construction and lookup of filters.Overall, there is ongoing dialogue within the Bitcoin community about the balance between privacy and transaction notification in Bitcoin wallets. Various proposals and ideas are being discussed to improve the usability and efficiency of Bitcoin wallets while considering the trade-offs involved. Feedback from users and developers is being sought to further refine these proposals.
