Bitcoin Optech newsletter #204 is here:
- summarizes continued discussion about adding package relay to the Bitcoin P2P network
- shares a summary of the recent LN developers meeting
- describes an argument for how spenders and routing nodes on LN can optimize for both reliability and low fees in a way that benefits both groups
Late but worth it! bdk 0.19.0 brings experimental taproot 🥕🥕🥕 support including tr() descriptors, taproot PSBTs, signing key and script spend taproot PSBTs, and tr() in descriptor! macros. Plus new OldestFirstCoinSelection, a sqlite-db fix, and more, see: https://github.com/bitcoindevkit/bdk/releases/tag/v0.19.0

'kubectl': The definitive pronunciation guide
The official pronunciation in this house is the one that most easily rolls off the tongue:
"CUBE ECK TAL"
...but I concur with his takeaway, and raise him a completion:
source <(kubectl completion bash )
complete -F __start_kubectl k
New issue of The Lightning Lab newsletter!
Back to the Bitcoin Future: Now's the Time to Build With Lightning
Built an enclosure for an Antminer S9, to manage sound and heat.
- Duct quick-connects for easily swapping intake/exhaust
- Finished w/speaker carpet over 1/4” padding for appearance and sound reduction
- Sound reduction from muffler on exhaust, baffle+underhood material on intake side
- Power & Ethernet extensions, will primarily control remotely
Made a few tiny adjustments to account for
cut width, should be easy to figure out.
Bitcoin Optech newsletter #202 is here:
- describes experimentation by developers working on silent payments
- HWI 2.1.1 and LND 0.15.0-beta.rc3 releases
Meanwhile, took the opportunity to install LIT on my raspiblitz. Web-based GUI looks pretty slick. I think I will try out the new Lightning Pool feature, even though I have special need for more inbound liquidity, I'm really curious to see what it's like making a bid and getting it filled:
Have run these ⚡️ benchmarks on a 64bit RaspberryPi4 with a USB SSD and got relieved that this common setup is not a bottleneck for the Lightning Network.
Find all the details and how to reproduce the results here: https://github.com/openoms/lightning-benchmark/blob/master/install.aarch64.md

We've been digging a little deeper into Lightning node performance 🤓

Peer-To-Peer Is Patriotic.
"Peers freely electing to interact with each other could be used to describe citizens constituting a constitutional republic such as the United States of America or nodes in the nebulous network of Bitcoin."
Worth a read; h/t @belcher
this is an oft-discussed scenario, I tend to think it will be a less significant effect than portrayed in this article; I am probably influenced by the history of bitcoin; I haven't seen evidence that prices are ever lower outside centralized exchanges (the opposite?), seems mostly surmise, not data.
The author may be under-stating the importance of the perfect verifiability (and doesn't understand intrinsic fungibility).
Learned of this via TFTC h/t @mattodell ;
there's a short video demo and a slide deck, basically this is a mobile-to-mobile BIP78 payment implementation (interestingly, seems to be iPhone) using onion service for receiver as Joinmarket does. Was part of an MIT hackathon.
Most interesting if this BIP78 implementation makes its way into production mobile wallets, will be a great selling point ...
My GUIX #Bitcoin bootstrapped deterministic build worked. After 4 days compiling through sources it was done.
