After a year inside the Ark protocol, the rabbit hole got way deeper.

What started with basic Bitcoin payments and batching has evolved into something much bigger: a complete execution layer.

Today we're announcing the next chapter: Arkade

Our journey began implementing Ark's core primitives: VTXOs, presigned transaction trees, and batch settlements.

Months of production code revealed to us these weren't just payment optimizations, they were the building blocks for something far more ambitious.

That realization changed everything.

We're unveiling Arkade: a virtual execution layer that transforms these primitives into programmable money while preserving Ark's security guarantees.

This announcement is also an opportunity for us to share our implementation journey.

Everything we've built developing Arkade is now open source.

Follow our evolution through code, research, and real implementation work:

🔧 Arkade Compiler (experimental Ivy meets CashScript) h/t @danrobinson

Arkade Language lets you write Bitcoin-native smart contracts in a high-level syntax, compiling to Arkade Script for fast, secure, offchain execution.

github.com/arkade-os/compiler

📱 Arkade Mobile Wallet (PassKey auth, no app store required)

A progressive web app with modern authentication and VTXO management built-in.

Arkade in your pocket

This is how Bitcoin wallets should work in 2025.

github.com/arkade-os/wallet

⚙️ Custom Script Interpreter

Conceptual implementation showing how enhanced scripting fits natively in our existing Ark infrastructure.

Features 30+ new opcodes including OP_CAT, introspection, and arithmetics, all VTXOs compatible

github.com/arkade-os/arkd/pull/577

Developers can dive in immediately with SDKs for Rust, Go, and TypeScript, making Arkade accessible across the entire Bitcoin dev ecosystem.

Follow along as we build Bitcoin's virtualization layer and we gear up for mainnet launch.

I’ve got a question for you guys and it might be incredibly dumb but anyway. nostr:npub1e85mms9s8ssm6vm6ztw0tdrr6j0a4l5gf2sjhw2scxpwnexmaxuqcev9em 2500

Obviously self custodial wallets are better than custodial because you have your own keys but surely if you rely on someone else’s node then you haven’t actually gotten rid of much trust compared to trusting them with your private key. My thinking is that if you trust their software to display the right number according to the Bitcoin blockchain then how easy is it for them to redirect a transaction meant for you to themselves and just display the number you were supposed to receive in your wallet.

Am I being retarded? +500 sats for good answers.

#asknostr

Only use self custodial wallets that are open source and that passed all the https://walletscrutiny.com/ tests.

Bonjour!

Ports that are blocked by browsers – Keenformatics – A (not so) tedious blog about informatics.

Turns out that some ports are explicitly blocked by browsers. This is done in response to the so-called Cross-protocol scripting vulnerability (VU#476267). Through this vulnerability, an attacker could forge malicious HTML code to send data to other services used by the victim (for example crafting spam emails, or printing through a network printer). IMAP, SMTP, NNTP and POP3 are just a small portion of the affected services.
