This was our @rawBit_io graduation call where we covered Taproot, Wrapped Segwit and more.
Congratulations to @andywong311 and Gradale who completely nailed the very first rawBit study cohort by exceeding the expectations with their results and attending 10 weekly sessions in a row. Well done guys!
Join the @rawBit_io study cohort tonight to:
- Build a 2-input P2WPKH transaction
- Understand shared midstate hashes
- See how SegWit ended quadratic hashing

On today's @rawBit_io call we discussed MultiSig, went through the exercises and discussed bip110, difficulty adjustment, potential 51% attacks and more. See you next Monday!

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.

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

One week left until we start our @rawBit_io study cohort.
- Scripts, SegWit, multisig, timelocks
- Hands-on with an interactive tool
- Accountability with bitcoiners

@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.

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 🫡
The students at @BitcoinBerlinSV are diving into the legendary Programming Bitcoin seminar by Jimmy Song! We’re forging the next generation of developers through decentralized, permissionless education in Berlín.
Support our initiative 🙏🇸🇻

🔥¡MUY bueno! lo de @rawBit_io
➤ (rawBit) es una herramienta para aprender a construir transacciones Bitcoin desde cero
-> puedes viajar entra todas las opciones:
-> No es evolución lineal… es evolución de:
-> privacidad, eficiencia, superficie de ataque, diseño de custodia
L1–2: 🟧 P2PKH (1...) | 🟥 P2PK | 🟧 P2SH (3...) | 🟨 multisig (legacy)
L3–4: 🟩 Timelocks (nLockTime/nSequence), CLTV/CSV
L5–6: 🟨 OP_RETURN, 🟪 Spilman payment channel
L7: 🟪 Pre-SegWit malleability
L8: 🟩 SegWit P2WPKH (bc1q...) BIP143
L9: 🟩 SegWit P2WSH (multisig & conditionals)
L10: 🟪 Fee savings: wrapped SegWit vs legacy
L11: 🟩 Taproot key-path (P2TR, Schnorr)
L12: 🟩 Taproot script-path (taptree, control block)
L13: 🟦 Taproot multisig (NUMS + OP_CHECKSIGADD)
L14: 🟦 MuSig2 (BIP327, aggregated Schnorr)

Should we start another weekly study cohort? 😇 Who’s in?
After learning this - try out rawBit - you can assemble raw Bitcoin transactions in visual way + check Script execution step by step

Thanks for the addition! You're right—each node reveals the underlying Python code, giving advanced users a deep dive into the mechanics. Love the vision of rawBit as a playground for exploring all Bitcoin tx types, new OPs, and concepts. Excited to see it evolve!

Replying to @rawBit_io @nic_carter
Nic's analysis captures real trends: incentivized AI slop has flooded feeds (per user complaints and reports), crypto's shift to stable assets reduced hype, and X's For You algo prioritizes broad appeal over niches (evidenced by 2025 updates reducing crypto reach 40-80%).
For niche visibility: Focus on X Communities, build email lists/Telegram groups, cross-post to Substack, and create evergreen content that sparks genuine engagement. Diversify to avoid algo dependency.
