The parable of Ruritania:
So BIP78 has been merged (no, don't ask me what that means!) and even has a test vector:
It's interesting how much debate there was about tiny subtleties of fee choice and restriction, and what each side checks - even the most trivial 2 party protocol can be hugely complex with interactivity.
Can't argue with that logic. https://autofreak.com/the-expanse-season-5-release-date-cast-plot-and-everything-detailed/44532/
A new blog post about the gridchain case (see earlier report from OXT Research):
Optech 102 ( https://bitcoinops.org/en/newsletters/2020/06/17/) talks a bit about WabiSabi.
I did spend some time analysing this crypto construction (at the prompting of @nothingmuch and others) but I mostly ended up getting lost in years-old crypto papers (and even finding an error in a 2013 paper security proof) and never really fully analysed the actual idea before getting sidetracked with a million other things ...
Anyway it's a very cool if rather sophisticated idea! Give it a read.
A 0.6.3 release for Joinmarket is imminent, which will be the *last release supporting Python 3.5*.
(next will be py3.6 and above, only, and will be a big change including psbt and other stuff)
Please run the current commit, if you have a chance, to sanity check if there are any final bugs to fix:
@fiatjaf Following up on this after two weeks of use: Fraidycat is great! This is the way I want to follow everyone and everything going forward. One feature I've come to especially appreciate is being able to partition certain people into the Occasional or Sometimes categories---e.g. people who I generally like and want to keep track of but whose political opinions or other content annoys me if I have to see it too often.
Thanks again for the recommendation!
This contains a great writeup on the fee overpayment weakness in BIP143. https://twitter.com/bitcoinoptech/status/1270671824062275586
Optech's news section is particularly excellent this week, kind of required reading (topics are LN eclipse attacks and the segwit double signing attack on hardware wallets - warning there is a *lot* of nuance in this topic, but they break it down better than I've seen anywhere else):
This week's Bitcoin Optech newsletter is up https://bitcoinops.org/en/newsletters/2020/06/10/
I would be heart broken if other hardware wallet fix this like Trezor did. I spent lots of time coding hardware wallet support on BTCPay Server (and the BTCPay Server Vault).
We will have to stop supporting hardware wallets completely depending on how vendors behave. :( https://twitter.com/BtcpayServer/status/1268544252247715849
