This has been brought up several times in the past, and I agree with Jonas' comments about users being unaware of the privacy losses due to BIP37. One thing also mentioned before but not int he current thread is that the entire concept of SPV is not applicable to unconfirmed transactions. SPV uses the fact that miners have committed to a transaction with work to give the user an assurance that the transaction is valid; if the transaction were invalid, it would be costly for the miner to include it in a block with valid work.
Transactions in the mempool have no such assurance, and are costlessly forgeable by anyone, including your ISP. I wasn't involved in any debate over BIP37 when it was being written up, so I don't know how mempool filtering got in, but it never made any sense to me. The fact that lots of lite clients are using this is a problem as it gives false assurance to users that there is a valid but yet-to-be-confirmed transaction sending them money. -Tadge _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
