Liana 13.0: Encrypted Descriptor Backups, Fiat Conversion, and Improved Usability

This release introduces encrypted descriptor backups, a major step toward safer, simpler self-custody, along with optional fiat value display, a re...

I like Bitcoin

This "trojan horse" bullshit isn't working the way you believe. It's about telling people holding zombie stocks is the same as holding a hard asset. It's about these "companies" not even keeping their own coins, but putting it all at custodians. So when it's gone, they won't take the blame. Just hold your own bitcoin, stop chasing extra return that will end up costing you everything.

I guess when the "treasury company" bubble burst, they'll all go down together. Cheap coins then!

Liana v11 brought the multi-wallet feature, v12 will bring a tab view and split view so you can open and see multiple wallets at the same time. It was one of the big hurdle I had managing multiple Liana wallets on the same PC

I was AFK for 2 weeks, traveling to the @Bitcoin FilmFest and @The Bitcoin Conference in Warsaw and Vegas. Both were great events. As usual a the large one, the techies are in their corner, the "open source stage" which has a workshop area, the Nostr zone and a proper stage for talks. These 2 events are very far from my hardcore technical gatherings, and a great reminder that Bitcoin users aren't just on X or here on Nostr, many are just random people with some btc somewhere. Sadly not enough in self custody, but hey, that's our job to fix.

We are doing some user interviews to figure out what would the perfect "inheritance dashboard" look like for your family. Basically once they access your coins for the first time, after you pass away. Are they technical enough to figure out how to unlock their Hardware wallet? To set up their own wallet? When you die, would they just want to dump the coins and be done with it? We want to make sure your family will be able to get the coins and do what they want with them, it's not easy! Manu from our team want's to hear from you, even if it's just random thoughts.

Bitcoin Custody for Organizations – Research Interview - Manuel Gatti

We're exploring new ways to improve Bitcoin key management for organizations. This short call is part of early product research to better understan...

My god, here is even worse than Twitter regarding the uneducated op_return takes? There has been so much content put together, how can people still not understand anything about how Bitcoin works? Understand where the "spam" and other data is currently put in Bitcoin first. Hint: not in op_return. Then understand why there is mining centralization and services like Slipstream and others. Then understand the different level of harm different ways of writing stuff to Bitcoin does, and how to possibly mitigate each of them. Then decide if these mitigations are worth it, in their current form. I believe pretty much everyone wants to get rid of non-transactional data, or at least jpeg spam. The problem isn't what we want, is what we can do today, and what impacts it has. Once you can argument how we can prevent jpegs to enter Bitcoin, in a way that does not involve a strong censorship committee that can also block legit transactions, it will get added to Bitcoin. Until then, it's all virtue signaling. And NO, removing OP_return won't do anything to jpegs. But you know that already.

Just created a Delving Bitcoin post. How to make sure users don't reuse xpubs across wallets?

Portugal (mainland) still without power. Most data/phone network seems down too now, that's why you don't hear from them much.

Rust-miniscript CVE 2025-43707: the @Liana Wallet team found a bug while preforming extensive testing on our v10rc1. I'm super proud of the team for contributing to Bitcoin security while showing how to build and test wallets. Also thanks to Antoine who now works at Chaincode, and did the CVE report and responsible disclosure to the @Blockstream miniscript team.
