00:42:57 Mercury Wallet releases mercury-node, a lightweight Bitcoin Lightning node implementation [Announcement/Project Github]
00:44:21 Parmanode by ArmanTheParman: An easy AF Bitcoin Node installation/verification/menu for desktop Linux [Announcement/Github]
00:44:48 LNProxy.org
Creates wrapped invoices
VPN-like privacy but for lightning
Usage:
Request that an lnproxy relay generate a “proxy invoice”: an invoice with the same payment hash
Once you verify the amount and payment hash, you can use the proxy invoice wherever would have used the original invoice and know that the only way for the payment to succeed is for the lnproxy relay to pay the original invoice.
When an lnproxy relay accepts an htlc for the proxy invoice, it immediately pays the original invoice and uses the revealed preimage to settle the proxy invoice, so you don’t need to trust lnproxy relays with your payments.

Preventing stranded capital with multiparty channels and channel factories
John describes how always-available nodes can continue using their funds to forward payments even when they share a channel with a node that’s currently unavailable (such as the user of a mobile LN wallet). This requires the use of multiparty channels.
He also restates a known benefit of channel factories of allowing channels to be rebalanced offchain, which may also allow better use of capital. He describes how to use both benefits in the context of his previous innovation of the tunable penalty layer for LN.
00:59:34 245
Watchtower accountability proofs
Sergi Delgado Segura posted about holding watchtowers accountable for failing to respond to protocol breaches they were capable of detecting.
For example, Alice provides a watchtower with data for detecting and responding to the confirmation of an old LN channel state; later, that state is confirmed but the watchtower fails to respond. Alice would like to be able to hold the watchtower operator accountable by publicly proving it failed to respond appropriately.
01:00:49 246
Splicing specification
Ongoing work on the draft specification for splicing
Splicing allows some funds in an offchain LN channel to be spent onchain (splice-out) or for onchain funds to be added to an offchain channel (splice-in). The channel can continue to operate while an onchain splicing transaction is waiting for sufficient confirmations.
Proposed BIP for transaction terminology
Mark “Murch” Erhardt posted the draft of an informational BIP to the Bitcoin-Dev mailing list that suggests a vocabulary to use for referring to parts of transactions and concepts relating to them.

Bitcoin
01:01:16 The Bitcoin Whitepaper Is Hidden in Every Modern Copy of macOS [Andy Baio Blog Post]
Lightning
01:02:56 Resizing Lightning Channels Off-Chain With Hierarchical Channels [Proposal]
Dynamic management of Lightning channel capacity is required to support efficient Lightning Network (LN) payments
On-chain resizing introduces delays, adds costs and limits scalability
Fast and cheap resizing may be required to support watchtower-free LN payments for casual users
Channel factories allow off-chain channel resizing, but only by exchanging capacity within a single factory
Hierarchical channels allow flexible, off-chain resizing of channels
They don’t require an exchange of capacity within a limited pool of users
They also support watchtower-free casual users without stranding any channel capacity
Hierarchical channels do for channel capacity what the LN does for bitcoin
No change to the underlying Bitcoin protocol is required

Nostr
01:12:17 [Civ Kit: A Peer-to-Peer Electronic Market System] proposed by Nicholas Gregory, Ray Youssef & Antoine Riard [Whitepaper]
A peer-to-peer market system to enable censorship-resistant and permissionless global trading in all parts of the world. While the design aims in priority to serve on-ramp/off-ramp trading, it can be extended to support any kind of trading: goods, services, bitcoin financial derivatives like discreet log contracts.
The design combines the Nostr architecture of simple relays announcing trade orders to their clients with Lightning onion routing infrastructure therefore granting high-level of confidentiality to the market participants.
The market boards are Nostr relays with a Lightning gateway, each operating autonomously and in competition.
The market boards can be runned as a federation however there is no “decentralized orderbook” logged into the blockchain.
The trades are escrowed under Bitcoin Script contracts, relying on moderations and know your peer oracles for adjudication.

01:20:55 Sweden to increase data center taxes by 6,000% [Coindesk]
The last remaining stronghold of bitcoin miners in Europe, is abolishing tax incentives for data centers in July – potentially putting the last nail in the coffin for the industry in the region.
The tax will increase from SEK 0.006 ($0.0006) to SEK 0.36 ($0.035) per kilowatt hour (kWh) starting July of this year, according to the financial budget published in November 2022
The upcoming tax will likely stop any new investment in Sweden, which is currently home to about 150 megawatts (MW) of mining.
