Merged PR from kallewoof: BIP-325: Signet [consensus] https://github.com/bitcoin/bitcoin/pull/18267
Who's up for some signet? Next week's Bitcoin Core PR Review Club meeting is on PR 18267 "BIP-325: Signet" by the ever-patient Kalle Alm (kallewoof). If you've ever wondered how to create a new chain, or the how and why of signet, join us on Wednesday hosted by Matthew Zipkin (pinheadz).
Notes and questions are up at:
Joinmarket 0.7.0 release published:
BIP78 payjoin is the main user-noticeable change, you can pay in Qt or on command line, to https servers or onions, with a p2sh wallet or a native bech32 wallet. URIs can just be pasted in and recognized.
There's a lot of other stuff in the background e.g. basic PSBT support. Make sure to read the release notes if you need to upgrade. Py3.6 is a requirement now.
Next Wednesday's Bitcoin Core PR Review Club is on PR 19339 "Re-delegate absurd fee checking from mempool to clients" (rpc/rest/zmq, tests, validation, wallet).
Notes and questions are up -- thanks Gloria Zhao for hosting.

I saw Lloyd Fournier reference this rather interesting new paper on generalized payment channels in a github thread:
One thing it covers (IV C) is single signer ECDSA adaptor signatures (of the type I covered in the recent blog "schnorrless scriptless scripts") and has some thoughts on security reductions for them (and indeed adaptor signatures in general).
(though, to be clear, that is definitely not the main topic of the paper).
I can recommend this as a good discursive read for the casually interested, about what Schnorr signatures are and where they come from:
I believe more blog posts from Nadav to come on this topic. Also if you like you can watch my youtube from summer 2018 on the London Bitcoin Devs ("Unfairly Linear Signatures").
Next week's Bitcoin Core PR Review Club is on PR #19160 "Multiprocess: Add basic spawn and IPC support."
