These days everyone seems to be rather busy being anti-this and anti-that and anti-everything-in-between.

You know what? I'd rather people tell me what they actually stand *for*, not everything they are *against*.

A while ago, for the one-year anniversary of the Bitcoin Core PR Review Club (@BitcoinCorePRs), Antoine Riard collected some comments---many which mentioned @jfnewbery. The comments are public, but today I'd like to tweet some of the things people said about this amazing mentor.

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:

I'm publishing my work diary following week-by-week all the work I do on bitcoin privacy. gist.github.com/chris-belcher/ It may be interesting to anyone who wants to follow how my projects, such as CoinSwap, are going

Got blown away by the UX of @CryptoAdvance Specter!
One thing is the great looking browser interface and app option, but connecting to Bitcoin Core only under the hood makes me more excited than any button!

@verretor I call anyone who contributes to any Bitcoin project a "Bitcoin contributor". If they contribute to Bitcoin Core, then I call them a "Bitcoin Core contributor".

App stores have a track record of acting capriciously & are also easy targets for gov't censors (including Trump). This is why alternatives like @fdroidorg are so important for user freedom.

@SimpleAristocrats Anything new is going to be risky. That was true once of Bitcoin multisig (hello off-by-one bug), P2SH (hello 520 byte push limit), and segwit (hello fee overpayment attack). It'll also be true of schnorr. However, one of the nice things about the commitment to soft forking in new features is that they're optional---you don't need to use P2SH or segwit if you don't want to and you'll also be able to let other people take the early adoption risk of trying schnorr/taproot.

Writeup on #bitcoin network topology. Didn't read it all, but looks like a nice writeup, especially if you've ever been confused about what a full node is, or how a miner interacts with the network, or how a wallet on your phone works.

@Sosthene I've been having problems myself with anxiety for the first time in years---and I haven't even been directly affected by covid in any big way (e.g. my income is still stable, nobody I know is sick, etc...). I can very easily believe there's a huge amount of psychological issues being created or made worse every day this goes on.
