This week we talked to @waxwing about Bitcoin privacy and SNICKER, a non-interactive two-party variant of coinjoin. We also discussed:

- Joinmarket
- Payjoin / p2ep
- Wasabi & Samourai Wallet
- Confidential Transactions
- Zcash & Monero

Be sure to check it out!

@FreePietje Well I find you ridiculing the lack of my capabilities deeply offensive. Who do I speak to on Mastodon to ensure that people don't comment on my capabilities (or lack of) again? The NYT wouldn't publish the drivel that I am typing so why should FB, YT or Mastodon?

@michaelfolkson @jon @harding thanks for writing on this !

just noting: although most of the good first issues require Python or C++, there's also some "good first issues" that require only shell scripting knowledge; see for example

I've drafted an article for Bitcoin Magazine on Good First Issues for Bitcoin Core. If anyone has any feedback or suggested edits please let me know cc @jon @harding @orionwl

If you don't have the time to check out the Stephan Livera podcast w/ @jon on contributing to Bitcoin Core give the transcript a read. Was a great interview
