Hi Insiders. This is Tuma, open-source reporter from the Insider Edition.
This week’s update features the latest major release, v3.0.0, of BDK wallet. This version brings major API changes to the Rust wallet library.
We also cover the new release for Core-lightning, v26.04. This version activates splicing by default, improves privacy through message padding, and increases payment reliability.
We also discuss PR630 in ldk-node, which adds support for configuring a node as a BIP353 resolver for human-readable names.
We finally feature the recent pubilication of BIP361 and some interesting interviews from the MIT Bitcoin Expo.
Highlights from the bitcoin developer ecosystem
I spent 10+ hours in open-source developer calls in the Bitcoin ecosystem last week. Here is what caught my eye:
v3.0.0 is the latest major release for BDK Wallet, the descriptor-based wallet library written in Rust.
During the weekly call, on Tuesday 14th, BDK contoributors discussed the latest major release v3.0.0. Developers are now discussing which fof the new features will be included in the UniFFI bindings.
Major updates includes persistent UTXO locking, to keep track of those UTXOs that should not be chosen automatically for a transaction, it adds support for importing/exporting the Caravan wallet JSON format, and improves network handling by using the latest features from rust-bitcoin.
Moreover, due to some changes in the SQLite database, developers provided utilities to allow projects to upgrade from BDK versions older than v1.0.
v26.04 of Core-lightning, named “Negative Routing Fees” is out.
During the biweekly call, on Monday 13th, CLN developers reviewed the final release requirements for v26.04. The new version was officially published today, Monday 20th.
Splicing is now enabled by default, after the recent merge of its specifications, offering simple commands, such as
spliceinandspliceout, to manage channels without closing them. Moreover, messages are now padded to a uniform length, making it harder for attackers to infer node activity from message sizes.This release also offers improved payment reliability through parallel path-finding, allows users to include fees in the requested amount, effectively making receiver paying them, adds support for payment notes in
xpay, and allows to configure specific peer nodes to direct payments through.
PR630 in ldk-node is adding support for resolving BIP353 human-readable names.
During the biweekly call, on Monday 13th, LDK contributors discussed PR630 which aims to introduce the possibility to configure a node as an BIP353 human-readable names resolver.
BIP353 proposes a standard format to encode URI schemes in Domain Name Service (DNS) records. Basically, it allows to store Bitcoin payment information into human-readable strings which can be easily verified on hardware wallets.
PR630 allows to configure an LDK node to act as a human-readable address resolver for other nodes. The goal of the resolver is to translate the human-readable string into an actual payment instruction.
A BIPs Update
In the last days there was some movement in the BIP repository. Specifically, one new BIP has been published by BIP maintainer Murchandamus.

BIP361: Post Quantum Migration and Legacy Signature Sunset
Authors: Jameson Lopp, Christian Papathanasiou, Ian Smith, Joe Ross, Steve Vaile, Pierre-Luc Dallaire-Demers
Published On: Apr 14th, 2026
Layer: Consensus (soft fork)
BIP361 is a proposed soft fork to implement a post-quantum output type and to provide a multi-phase plan to sunset legacy ECDSA/Schnorr signatures. According to the authors, the goal is to make upgrading to post-quantum outputs a matter of incentives, providing a clear timeline to align the entire ecosystem.

Does Bitcoin scale?: BTC++ Insider reporter Niftynei chatted with Jonathan Harvey-Buschel, MIT graduate and Chaincode Labs researcher, about his work on the Lightning gossip protocol at the MIT Bitcoin Expo. See what he had to say about networking clusters, minisketch considerations, and how he’s repurposing insights from the Erlay paper to make the Lightning Network scale to the next 100k nodes.
Quantum FUD vs Quantum Compute: Bitcoin++ announced a one hour formal Oxford debate on the topic “Quantum FUD is a greater risk to bitcoin than quantum computers”. The Villain Edition conference will take place at the Hoover Dam this week, Thurs + Fri (Apr 23+24). Alex Pruden from Project Eleven will argue the negative; Brandon Black, the affirmative. David Zell, Director of the Bitcoin Policy Institute to moderate.
