   @josibake Sent you some, using a light client so I hope this worked.

   @setavenger received, 0.00021000! I tried sending it back but it appears your address is invalid PEBCAK. I’d like to keep this issue focused on the integration for Bitcoin Core, but feel free to join the silent payments IRC channel (#silentpayments) or reach out on twitter (@josibake) so we can keep testing!

   • Move base protocol to libsecp as a module (not started)

   FWIW, I’ve started digging a bit deeper into that and started a corresponding discussion in the libsecp256k1 repo: https://github.com/bitcoin-core/secp256k1/issues/1427 (still trying to figure out a sane interface…)

    From what I can see it will be possible to enable/disable Silent Payments support using the compilation flag, but most users don’t compile Bitcoin Core, they download it from the official website, and if the official release binary will have Silent Payments activated, this means that a lot of users will have code they don’t need in their nodes. From my point of view, Bitcoin Core should remain as minimal as possible, to decrease the surface of possible attacks, and to make it easier to update and maintain.

    I’m interested in exploring the reasons behind this choice. Sorry if this might not be the best place for discussion, in case, let me know where I can ask!

    Hey @Turtlecute33 , this issue is meant to track the status of the PRs and keep track of any follow-ups that might arise. I don’t think it’s a good place for a general discussion on what should or shouldn’t be in Bitcoin Core. I’m not sure of a good place for meta discussions about the project but I’m happy to continue this conversation in the #silentpayments IRC channel

    PRs ready for review:

    • Add BIP352 module (take 3) bitcoin-core/secp256k1#1698

    Add BIP352 module (take 3) bitcoin-core/secp256k1#1698 has been replaced with Add “silentpayments” module implementing BIP352 (take 4, limited to full-node scanning)

    Anyone looking to try out silentpayments on bitcoin-core can use #32966, which has sending and receiving support and works on the bitcoin-core gui.
