This lead is a little awkward. He is a slight improvement though not my favorite:

Suggested change

next week. The seminar focused on the role of Bitcoin technical

- **Grokking Bitcoin** Kalle Rosenbaum led a [Socratic

Seminar][] at London Bitcoin Devs and gave a presentation the

following week. The seminar focused on the role of Bitcoin technical

I'm not sure Kalle led the seminar (the transcript is unattributed for privacy, but it seemed to me that someone else was leading).

I've rebased on master since this wasn't a clean fast-forward merge.

Looks good. I've left a bunch of nits inline. Because my review is late, I've pushed those suggested changes in a commit. @harding - please feel free to revert any of those changes that you don't like.

+- **QR codes for large transactions:** QR codes can practically contain

+  typical user transactions but far too small to contain the largest

nit: I suggest removing "(about 400 kilobytes)". I believe you're right that the largest transaction allowed under standardness rules would be 101k vbytes, which would equate to 404k if the entire transaction consisted of witness. There's also overhead in the PSBT format, which carries additional data. I think it's best to just remove the number here.

+[Bitcoin Improvement Proposals (BIPs)][bips repo], and [Lightning

+
+*Note: the commits to Bitcoin Core mentioned below apply to its master


This boilerplate warning was added last week as well. What's the justification for doing this? Doesn't the same warning apply to commits for other repos?

This boilerplate warning was added last week as well.

Variations on the notice also appear in newsletters 9, 10, 11, 12, 13, 14, 37, 40, 41, 42, 43, 67, and 68. (Search for "master" in any of those newsletters.)

What's the justification for doing this?

Without the warning, I think people will expect the changes we describe to appear in the next Bitcoin Core release (e.g. 0.20 in a few weeks).

Doesn't the same warning apply to commits for other repos?

No. Both LND and C-Lightning RCs releases are just tags on their master branch. I think that's also the case for Eclair, but I'm not sure. Rust-Lightning has tags that GitHub shows as releases but there's no release notes and they're all version 0.0.x, so I've been assuming they're not real releases. The other repos don't do releases.

In short, AFAICT, Bitcoin Core is the only project we monitor that branches from master prior to a major release. (Indeed, I'm unable to think of any other free software project I've followed that does that.)

As an alternative to the warning, we could simply not report on Bitcoin Core commits to master during RC cycles, though that would leave us with a huge backlog when at the end of each cycle.

ah ok. Makes sense. Thanks!

Nice newsletter this week, team!

@harding @michaelfolkson and @rorp from Suredbits all authoring. Also thanks for edits from @jnewbery and reviews from @jonatack and @adamjonas

michaelfolkson · 2020-05-06T12:39:24Z

Thanks @bitschmidty. Very impressed with the rigor and thought that goes into these. I was already a fan but you get a new perspective trying to get something in. Keep me posted with how the transcript section is received. I'm interested in how much use people get out of the transcripts (if any) and which ones in particular are useful. Other than engagement with Bryan's tweets I am flying a little blindfolded on this. Thanks for all your work on this, it is a fantastic resource.
