Shoutout to @andywong311 Gradale, @Harrisbigboy89 and other bitcoiners on the call for contributing to the session. We went through the flows, built a raw transaction and even broadcasted it to the testnet! See you next Monday.

rawBit now has Help💡 Interactive tutorials that auto-assemble on the canvas full searchable docs. rawbit.io

Another nice call today, team. Special shoutout to Gradale, @andywong31 and @Harrisbigboy89 who shared their @rawBit_io transaction flows. Keep up the good work.

rawBit demo - refreshed design and grouped transaction flows ✨

First cohort of our raw Bitcoin TX course @CodeOrangeDevs just started. Today we built P2PKH from scratch in rawBit. Thanks to @HRF and @OpenSats for making it possible. x.com/CodeOrangeDevs/status/…

Join the rawBit transaction cohort ✨ In this cohort we will go through : P2PKH, P2SH, P2PK, multisig, timelocks (nLocktime, nSequence, CSV, CLTV). Building raw transactions visually on the canvas, executing Bitcoin Script and sending them to testnet. x.com/CodeOrangeDevs/status/…

One week left until we start our @rawBit_io study cohort. - Scripts, SegWit, multisig, timelocks - Hands-on with an interactive tool - Accountability with bitcoiners Sign up now: forms.gle/MfhS2u2dt13rJd4a8

@rawBit_io has been one of the most practical tools I’ve used to understand Bitcoin transactions. After a few weeks of hands-on use, the learning clarity is undeniable. It enables visual transaction building, live byte level inspection, and step-by-step script execution with a stack view. We’re looking to adopt it at @osguildHQ and @BitDevsMRU to strengthen hands-on Bitcoin education.

just shipped a rawBit flow that walks BIP39 mnemonic with address verification on a physical @Trezor. check it out in 'Flow examples' on rawbit.io @planb_network @TrezorAcademy

This is a nifty new visual bitcoin transaction builder & script debugging tool! x.com/i/status/1996554245412…

Today I’m giving a short intro live demo of raw₿it to the Vinteum community. discord.com/events/100363315… Would love to see some of you there! ⚡️ @Vinteum_org @lucasdcf @andreneves

rawBit features that make saving and organizing flows much easier ✨ Standard Save/Load, Simplified AI export, Share links, Groups and Flow Map

Most Bitcoin tutorials (like @ChristopherA excellent “Learning Bitcoin from the Command Line”) teach you bitcoin-cli. Great for real-world use, but they hide the internals. rawBit is different: you build transactions visually and see the exact Python code behind every node.

NEW: 🇹🇭 Bitcoin developers from Thailand launch Visual Raw Transaction Builder & Script Debugger 👀 An interactive tool to build and understand Bitcoin transactions visually. • Connect predefined nodes → see every byte update live • Step through script execution with live stack view • Full Python code behind each node 10 hands-on lessons included (P2PKH → SegWit, multisig, timelocks, payment channels, etc.) — all broadcast to testnet. More coming (Taproot, Lightning, covenants…). 👀👇

rawBit features that make flows much faster ✨ Multiple tabs, multi-select copy/paste, click-to-connect, Copy Inputs tool, and edge highlighting.

Bitcoin Under the Hood ⚡ An Intro to raw Transactions with Anika & rawBit

I'm teaching this awesome course by @jimmysong in Spanish to the Berlin students I'll add: @savingsatoshi game and the @rawBit_io platform to make it easier to understand ( some other tools) Building builders! Because we will need more Bitcoin Developers in the future 🫡

Want to contribute to rawBit? I’ve collected the main directions here: github.com/rawBit-io/rawbit/… Flows, docs, reviews, videos, bugfixes)

Very happy to start this with @CodeOrangeDevs . There is still time to register. Students will not only study raw Bitcoin tx from scratch, but also get the chance to contribute to rawBit under my mentoring and help build new flows. x.com/CodeOrangeDevs/status/…

rawBit is now part of Summer of Bitcoin 2026 🚀 Excited to explore new educational flows for Bitcoin protocols together summerofbitcoin.org/2026-org… @summerofbitcoin
