I think @bitcoinKeeper_ is the best Bitcoin Wallet to test stuff. If you change it to testnet you can just click on "receive testnet coins". It just works.

Helping with measurements to speed up the Specter DIY ESP32 P4 Port.

If you're a vibecoder looking for something useful to build for Jev: Build a clean browser tab manager plugin that automatically understands which tabs belong to the same task and groups them together. I would use this every single day.

We are very early. Every time I want to make a Tutorial about a Bitcoin App I see something that should be fixed. Logical Feature Request or Bug Fix.

You are only to allowed to choose one layout for your future @SpecterDIY. Which do you choose and why?

I’ve updated my offline web Bitcoin Inheritance Planner. Now you can see a detailed graphical overview of your Bitcoin Security Setup.

I do not get why human readable BIP-39 Seedphrases are not a Standard for Nostr yet. You could easily derive the Nostr Nsec from it and so you would help so many people trying to write their cryptografic nsec on paper.

With Specter DIY, we established an air-gapped connection via QR code.

I love BIP85. I have 10+ Bitcoin seed phrases and even more wallets. But it's enough to back up only one properly.

Highly appreciate!

Nostr-Schlüssel kann man schon jetzt aus jeder Hardware Wallet ableiten die BIP85 unterstützt:

Dein eigener Blog scheitert nicht am Schreiben, sondern oft schon an Hosting, WordPress und laufenden Kosten. Im neuen @Einundzwanzig Video zeige ich dir, wie du mit EINUNDZWANZIG Media ein Konto erstellst, einen Artikel schreibst und mit dem Nostr Protokoll veröffentlichst, andere Beiträge entdeckst sowie Bitcoin-Spenden über dein Profil empfängst.

Did you know that in 2018, while Specter DIY was still in early development, another DIY hardware wallet project was being built? It used Trezor 's open-source codebase. Today, almost nobody knows about it. PiTrezor adapted the Trezor One firmware to run on a Raspberry Pi.

Hatte vor einem Jahr einen 21-Euro Schein verschenkt. Die 14 Jährige hatte ihn bis heute in ihrer Handy-Hülle um ihn wo wenn möglich ihren Freundinnen zu zeigen.

Brauch nicht mehr sagen

Was able to connect the web Specter DIY Simulator I'm currently building with the Specter Desktop on my PC via simulated USB connection👀 Will release it soon

After my post someone sent me the simulator of mineracks which is amazing!

You can simulate: - any Hardware Wallet - any Software Wallet And let them communicate on Signet. It is a bit buggy cause he probably has the VPS architecture I had in the beginning but the communication between the Hardware Wallet and companion App works very well. Also probably it makes problems when to many people are using the site, as they are probably all using the same devices at the same time.😅 Highly recommend checking that out.

People use at least three different meanings of “Bitcoin Layer 2”: 1⃣Network L2: an interoperable protocol cryptographically pegged to Bitcoin in a trustless manner. It preserves Bitcoin’s peer-to-peer nature and disintermediated verifiability, and does not use IOUs.¹ 2⃣Broader technical L2: a protocol that extends Bitcoin’s functionality. Bitcoin is locked on L1 and represented or used on L2. This can involve additional trust in centralized actors or network operators, with eventual settlement back to Bitcoin.² Übersetzen mit DeepL 3⃣Monetary L2: any off-chain interaction that transfers a BTC balance from one entity to another, whether as an IOU or as actual ownership.¹ When I say “Bitcoin L2”, I mean definition #1. Under that definition, I do not consider Liquid, Cashu, Fedimint, or Spark to be Bitcoin Layer 2s. They can still be useful technologies built around Bitcoin. I just would not call them Bitcoin L2s. --- ¹ The Semantics of the Bitcoin Layers, Bitcoin Magazine bitcoinmagazine.com/culture/the-semantics-of-the-bitcoin-layers ² Bitcoin’s Layered Design: The Key to Greater Utility, Blockstream blog.blockstream.com/bitcoins-layered-design-the-key-to-greater-utility/

Bitsaga Rob built a SeedSigner Simulator in the browser. I did the same for Specter DIY even month before. But my build was bad. It run the Specter as a simulator on a VPS and connected to the VPS to the browser. Allowing only 5 persons at once using it. Never released it cause it was buggy. Only internally for testing the new Specter Firmware variations we are building. But now I saw how elegant Rob had implemented it. I'm now also rebuilding mine on micropyhtong directly allowing to simulate SD-Card, QR-Scanner and Smartcards. Updates soon
