Vulnerability Disclosures
00:05:16 “AJ Towns censoring on Delving Bitcoin to cover Bitcoin Core backdoors?” Stacker News Post
Claims being made by @theariard
Noticed vulnerabilities in Bitcoin Core PRs, questioned reviewers, proposed testing in real-world conditions, but was ignored.
AJ Towns revealed existence of private discussion rooms for Bitcoin Core contributors on Delving Bitcoin forum, bypassing transparency standards of FOSS.
Some vulnerable code enhancements pointed out publicly may have gone through this closed-door process.
Pieter Hintjens emphasized transparency’s importance in FOSS for rapid criticism of ideas and work in progress.
AJ Towns threatened to cancel account and deleted post after raising concerns about communication standards on Delving Bitcoin.
Concerns raised about potential insertion of backdoors in Bitcoin Core by subset of contributors for political motives.
Decision to cease engagement or contribution on Delving Bitcoin due to perceived lack of transparency.
00:13:43 LNbits Demo Server to Disable Cashu Extension
“Warning: if you have a mint running on the LNbits demo server, close it down. They just announced that they are going to rug all mints running on that server by end of March. Run your own infrastructure!” ~ @callebtc
“Seems some are using our demo server to run production ecash mints, using someone elses demo server for a service is irresponsible. We will disable the Cashu extension at the end of March, please move. Our demo server is JUST for testing, please don’t use for production services.” ~ lnbits

Keystache by Resolvr: Desktop Client for Managing Nostr Private Keys
Keystache is a desktop app that enables you to keep all of your nostr keys in a single application rather than pasting your nsec into every application you install on the desktop. It’s similar to the nostr support that web extensions like alby or nos2x provide.
Keystache provides an API (Over a Unix Domain Socket) for other MacOS desktop applications to request a public key (used to sign in to other apps) or request an event be signed.
Keystache works with Resolvr’s bounty desktop app (or any other desktop nostr client!) to zap bounty payouts (or any other zappable event!) with ANY bitcoin lightning wallet through a simple QR code interface

Lightning + L2+
Software Releases & Project Updates
1:20:36 Phoenix
Android v2.2.1
🇸🇰 Slovak and 🇻🇳 Vietnamese localisation
Settle in-flight payments in the background
When needed, Phoenix will run a background job to try to settle in-flight payments (incoming or outgoing). The objective is to avoid payment timeouts when the wake-up push notification from the ACINQ node fails. This is especially useful for devices that don’t support FCM notifications.
Android/iPhone v2.2.0
Use taproot addresses by default, and rotate addresses
The address displayed by Phoenix for on-chain to Lightning swaps is now a Taproot address. This address is not static anymore. Phoenix will generate a new swap-in address upon receiving a transaction. This improves privacy, and also makes deposits cheaper.

Trustless onchain betting on potential soft forks:
ZmnSCPxj posted to Delving Bitcoin a protocol for giving control over a UTXO to a party that correctly predicts whether or not a particular soft fork will activate
The basic idea has been proposed before but ZmnSCPxj’s version deals with the specifics expected for at least one potential future soft fork, [OP_CHECKTEMPLATEVERIFY] (https://bitcoinops.org/en/topics/op_checktemplateverify/).
Overview of Chia Lisp for Bitcoiners:
Anthony Towns posted to Delving Bitcoin a detailed overview of the Lisp variant used by the Chia cryptocurrency.
Towns has previously proposed a soft fork introduction of a Lisp based scripting language
Updating BIP21 bitcoin: URIs:

Salvatore Ingala posted to Delving Bitcoin about minimizing the amount of state needed to perform multiple [MuSig2] (https://bitcoinops.org/en/topics/musig/) signing sessions in parallel.
Ingala proposes generating a single state object for an entire [PSBT] (https://bitcoinops.org/en/topics/psbt/) and then deterministically deriving the per-input state from it in a way that still makes the result indistinguishable from random.
Discussion about adding more BIP editors:
Ava Chow posted to the Bitcoin-Dev mailing list to suggest the addition of BIP editors to help the current editor.
Also discussed was whether the additional editors should have the ability to assign BIP numbers.
GitLab backup for Bitcoin Core GitHub project:
Fabian Jahr posted to Delving Bitcoin about maintaining a backup of the Bitcoin Core project’s GitHub account on a self-hosted GitLab instance.
Jahr provided a preview of the project on GitLab and plans to keep backups going forward to allow rapidly switching to GitLab if necessary.
Trustless contract for miner feerate futures:
ZmnSCPxj posted to Delving Bitcoin a set of scripts that will allow two parties to conditionally pay each other based on the marginal feerate to include a transaction in a future block.
Coin selection for liquidity providers:
Richard Myers posted to Delving Bitcoin about creating a coin selection algorithm that is optimized for LN nodes offering liquidity via liquidity advertisements.
His post describes an algorithm that he implemented in a Bitcoin Core draft PR. Testing the algorithm, he found “a 15% reduction in on-chain fees compared to Bitcoin Core’s default coin selection”.
Simple vault prototype using OP_CAT:
Developer Rijndael posted to Delving Bitcoin about a Rust-language proof-of-concept implementation he’s written for a vault that only depends on the current consensus rules plus the proposed OP_CAT opcode.
Sending and receiving ecash using LN and ZKCPs:
Anthony Towns posted to Delving Bitcoin about linking “[ecash] (https://bitcoinops.org/en/topics/ecash/) mints to the lightning network without losing ecash’s anonymity or adding any additional trust”.
His proposal for achieving that goal uses a zero-knowledge contingent payment (ZKCP) for sending payments to the user of an ecash mint and a process of committing to a hash preimage for withdrawing ecash funds to LN.
DNS-based human-readable Bitcoin payment instructions:
Matt Corallo posted to Delving Bitcoin a draft BIP that will allow a string like example@example.com to resolve to DNS address such as example.user._bitcoin-payment.example.com, which will return a DNSSEC-signed TXT record containing a BIP21 URI such as bitcoin:bc1qexampleaddress0123456.
Thinking about mempool incentive compatibility:
Suhas Daftuar posted to Delving Bitcoin several insights into the criteria full nodes can use to select which transactions to accept into their mempools, relay to other nodes, and mine for maximal revenue.
Daftuar notes:
Pure replace by feerate doesn’t guarantee incentive compatibility
Miners with different hashrates have different priorities
Finding incentive-compatible behaviors that can’t resist DoS attacks would be useful
Cashu and other ecash system design discussion:
Several weeks ago, developer Thunderbiscuit posted to Delving Bitcoin a description of the blind signature scheme behind the Chaumian ecash system used in Cashu, which denominates balances in satoshis and allows sending and receiving money using Bitcoin and LN.
Developers Moonsettler and Zmnscpxj replied this week to talk about some of the constraints of the simple version of blind signing and how alternative protocols might be able to provide additional benefits.
Continued discussion about 64-bit arithmetic and OP_INOUT_AMOUNT opcode:
Several developers have continued discussing a potential future soft fork that could add 64-bit arithmetic operations to Bitcoin
Also discussed was whether to use signed integers or only allow unsigned integers, and whether to allow operating on larger numbers, potentially up to 4,160 bits.
Chris Stewart created a new discussion thread for a draft BIP for an opcode originally proposed as part of OP_TAPLEAF_UPDATE_VERIFY
The opcode, OP_INOUT_AMOUNT pushes to the stack the value of the current input (which is the value of the output it is spending) and the value of output in the transaction that has the same index as this input.
If the opcode were added to Bitcoin in a soft fork, it would make it much easier for contracts to verify that the input and output amounts were within the range expected by the contract
Improved reproducible ASMap creation process:
Fabian Jahr posted to Delving Bitcoin about advancements in creating a map of autonomous systems (ASMap) that each control the routing for large parts of the internet.
The ASMap project aims to provide approximate information about which ISPs control which IP addresses directly to Bitcoin Core
A major challenge faced by this project is allowing multiple contributors to create a map in a reproducible manner, allowing independent verification that its contents were accurate at the time it was created.
Jahr described the tooling and techniques that he says has “found that there is a good chance that within a group of 5 or more the majority of participants will have the same result.”

Lightning
Richard Meyers proposed a coin selection and UTXO management algorithm tailored for liquidity providers.
Problem: Current wallets are not optimized for liquidity providers like Lightning nodes.
Characteristics of liquidity provider wallets:
Frequently spend utxos of known amounts for liquidity transactions.
Infrequently refill the wallet when the balance is low.
Liquidity transactions may not confirm before the next spend.
Liquidity transactions may not confirm at all due to inputs from other wallets.
Goal: Fund liquidity transactions with a single input and no change output to minimize fees and avoid tying up funds.
Proposed Solution:
Import a user-defined set of target utxos for liquidity transactions.
Proactively refill buckets in low fee rate situations or when a bucket is extremely depleted.
Opportunistically refill buckets if coin selection adds a change output.
Split the change output, if any, to refill buckets.
Testing:
Tested using a modified fork of coin_selection_simulation and changes to Bitcoin core in draft PR #29422.
Results:
Initial results show a 15% reduction in on-chain fees compared to default coin selection.

Apple PWA ban halted Announcement
Apple will continue to let users put web apps on their home screens after iOS 17.4 arrives. They will, however, have to be “built directly on WebKit and its security architecture,” rather than running in alternative browsers.
Apple announced that they “have received requests to continue to offer support for Home Screen web apps in iOS, and will continue to offer the existing Home Screen web apps capability in the EU. The support means Home Screen web apps continue to be built directly on WebKit and its security architecture, and align with the security and privacy model for native apps on iOS.”
Apple added that “Developers and users who may have been impacted by the removal of Home Screen web apps in the beta release of iOS in the EU can expect the return of the existing functionality for Home Screen web apps with the availability of iOS 17.4 in early March”
