I created a short and simple tutorial on how to make silent payments on signet. https://gist.github.com/w0xlt/72390ded95dd797594f80baba5d2e6ee In this tutorial, the user will generate an address, publish it, receive and spend coins from it and still no transactions are shown from this address in a blockchain explorer.
Hi woltx,
Thanks for implementing silent payments in Bitcoin Core. I tried the steps shared in tutorial and everything works as expected.
I have updated the silent payment address (signet) as TXT record for domain alice.silentbitco.in
$ dig -t txt alice.silentbitco.in +short "tb1px3kma8e8y8z9l7e640v0x2chzrzww9cu06mqvwyrz805ffletu3s067sgh"
I have also added basic information about silent payments proposal, implementation and tutorial on https://silentbitco.in
I had no issues with performance of the UTXO Set and the blocks scan. I don't mind using flag but a new address/descriptor format should be a better approach. I could not review the code in detail or test edge cases however these suggestions by Pavol Rusnak make sense: https://gist.github.com/RubenSomsen/c43b79517e7cb701ebf77eec6dbb46b8?permalink_comment_id=4177027#gistcomment-4177027

i like the 00 || X_spend || X_scan + mandate address reuse prevention.
might as well start with something strict
easy to loosen it later - if needed - harder to tighten it later because of back-compatibility with addresses in-use
