Building the open-source developer community that keeps Bitcoin free, decentralised, and unstoppable — from Southeast Asia to the world.

Globally, only ~41 developers power the $1.7 trillion Bitcoin Core codebase. Across all of Southeast Asia — 700 million people, many living under currency debasement, capital controls, and financial surveillance - that number is close to zero.

Code Orange Dev School exists to fix that.

Founded by Keypleb, co-founder of Bitcoin Indonesia (40+ monthly meetups across 40 cities, ~55,000 Bitcoiners engaged) and Bitcoin House Bali, Code Orange is a Bitcoin-only, open-source developer education program training regular developers and technical Bitcoiners into active open-source contributors. Our graduates don't just learn about Bitcoin — they build it, run it, review it, and teach it.

All curriculum is free and open-source. All materials are published on GitHub. Every graduate is a permanent asset for the Bitcoin ecosystem.

"If someone in Asia wants to become a Bitcoin open-source contributor, Code Orange is the starting point.”

Before we explain what we do, here's what we've already done:

• 21 graduates from our Bitcoin Dojo cohort (partnership with Chaincode Labs BOSS Challenge) — 49 registrants, 7-week intensive building Bitcoin primitives from scratch. Graduates now pursuing Good First Issues across Bitcoin Core, rust-bitcoin, and BDK.
• 13 active contributors from our Decoding Bitcoin cohorts are now contributing to Bitcoin open-source projects — with 75+ PRs opened and 45+ merged to Bitcoin Core, rust-bitcoin, BDK, rust-payjoin, rust-lightning (LDK), peer-observer, hex-conservative, rust-miniscript, and more.

• Privacy Track — 12-session curriculum covering chain analysis defence, Silent Payments (BIP352), Payjoin (BIP77/78), CoinJoin, and privacy-preserving wallet development. Built with guest speakers from Fedi, Nunchuk, and the Bitcoin privacy community.
• rawBit Study Cohort launched (10 weeks) - building raw transactions from scratch with @rawBit_io, the open-source visual transaction builder.
• Developer community spanning 8 countries — Indonesia, India, Romania, Nigeria, Kenya, Zambia, Brazil, and South Korea — with contributors working across privacy protocols (BIP352 Silent Payments, BIP77 Payjoin), Rust Bitcoin infrastructure, Lightning tooling, and Bitcoin Core itself.
• Peter (@pzafonte) contributing to Bitcoin Core — PR #34885 to the most critical Bitcoin project, plus Silent Payments integration into kernel-node.
• Keypleb, active bitcoiner in the community Bitcoin Asia 2026 speaking at local and international Bitcoin conference - representing Southeast Asian Bitcoin developer education on the global stage.
• Sovereign Bitcoiner Mastermind hosted at Bitcoin Indonesia Conference 2025 — Bali's flagship Bitcoin event (250+ attendees, alongside speakers like Alex Gladstein).
• Biweekly in-person workshops at Code Orange Dev Schoo, Canggu, Bali.
• Part-time Bitcoin educator jobs created through our train-the-trainer program — building a sustainable technical educator economy.

Structured, peer-driven learning tracks taking developers from foundational Bitcoin knowledge to active open-source contribution. Full syllabi, exercises, and facilitator guides are in our open-source curriculum repo (CC0 licensed).

Recommended learning path:

Bitcoin Dojo (7 weeks) → rawBit (10 weeks) → Decoding Bitcoin (8 weeks) → Privacy Track (12 sessions) → Open-source contribution

• Bitcoin Dojo (7 weeks) — Build Bitcoin's cryptographic primitives from scratch using Jimmy Song's Programming Bitcoin. Partnership with Chaincode Labs BOSS Challenge. Covers finite fields, elliptic curves, ECDSA, keys, addresses, and transaction construction. 49 registrants, 21 graduates in our first cohort — many now pursuing Good First Issues across Bitcoin Core, rust-bitcoin, and BDK.
• rawBit Study Cohort (10 weeks) — Build raw Bitcoin transactions from scratch using rawBit, an open-source visual transaction builder and Script debugger. Covers legacy transactions, multisig, timelocks, SegWit, and Taproot — all hands-on with an interactive tool. In partnership with @rawBit_io.
• Decoding Bitcoin (8 weeks) — An intensive cohort where participants self-study Bitcoin transactions, Scripts, Taproot, PSBTs, and Bitcoin Core contribution workflows through hands-on sessions. Built on world-class open-source resources from Chaincode Labs and the Bitcoin Dev Project. Our 2nd cohort produced 12 graduates now contributing to Bitcoin open-source software.
• Sovereign Bitcoiner Crash Course (5-10 weeks) — A hands-on deep-dive covering full node operation (Umbrel), BitAxe mining, multisig setup (Nunchuk, Casa), inheritance planning, BTCPay Server deployment, and privacy tools (eCash, Fedimint). Graduates leave with deployed, working systems — including a running node, a BTCPay server, and a multisig inheritance plan. Also covers Bitcoin culture: why we run nodes, why self-custody matters, and how to defend against the $5 wrench attack.
• Privacy Track (12 sessions, biweekly) — Our most advanced curriculum. Covers chain analysis defence, CoinJoin mechanics, Silent Payments (BIP352), Payjoin (BIP77/78), Tor integration, Lightning privacy, and contributing to privacy-focused Bitcoin FOSS. Graduates leave ready to submit PRs to projects like rust-payjoin, Fedimint, and Wasabi. Built with input from Fedi, Nunchuk, and the Bitcoin privacy community.
• Vibe Coding on Nostr (Monthly) — Monthly workshops exploring Bitcoin-adjacent open-source development: building on Nostr, Lightning integrations, and FOSS tooling. Now includes in-person OpenClaw workshops at Bitcoin House Bali.
• Monthly Bitcoin Reading Club — Every 4th Wednesday, an ongoing peer-learning community for technical Bitcoiners.

Practical, hands-on workshops at Bitcoin House Bali and beyond, where participants leave with deployed, working Bitcoin infrastructure. Topics include:

• Bitcoin mining — BitAxe setup, Braiins, Stratum V2, solo mining (BitAxe Workshop)
• Multisig & key management — Nunchuk, Casa, SeedSigner, hardware signers, inheritance planning
• Full node operation — Bitcoin Core + Lightning node deployment via Umbrel
• Private eCash payments — Fedimint, Cashu, chaumian ecash protocols
• Nostr — Identity, relays, NIPs, and building on the open protocol
• BTCPay Server — Merchant self-custody payment infrastructure
• Privacy tools — CoinJoin, PayJoin, Tor integration
• Off-grid living — Bitcoin self-sovereignty beyond the grid

Delivered in English and Indonesian — making technical Bitcoin education accessible across the entire region.

Bitcoin education scales through community, not curriculum alone. We are building the physical and social infrastructure for a Southeast Asian Bitcoin developer network — targeting to inspire 10 more Bitcoin Houses across the region by end of 2027.

Our flagship hub, Code Orange Dev School, is a converted structure of Bitcoin mining containers in Canggu (Part of Awan Connection) that serves as a community hub and education centre — hosting workshops, co-working, and technical Bitcoin education sessions. We are replicating this model to launch community-led hubs across Thailand, Vietnam, Indonesia, Malaysia, Korea, and beyond.

Code Orange is not just a community — it is a pipeline into the global Bitcoin open-source developer ecosystem. We identify exceptional graduates and actively guide them toward:

• Fellowship and education programs at Chaincode Labs, base58, ₿Trust/Qala, and Vinteum
• First contributions to Bitcoin Core, Lightning, Fedimint, BDK, rust-bitcoin, rust-payjoin, and related projects
• Grant applications to OpenSats, HRF, and Brink
• Active participation in the global Bitcoin developer community: mailing lists, IRC, pull request review processes

We headhunt and empower technical community leaders at Bitcoin hubs across Asia to independently run Code Orange workshops. Monthly train-the-trainer sessions maintain curriculum quality and ensure our educational model scales without centralising. This program creates local gig-economy jobs for Bitcoin educators — building a self-replicating education network across the region.

We equip communities with practical Bitcoin payment infrastructure for everyday use: Fedi federated mints, Koral, and PlebQR — giving everyday users across Asia access to real, sovereign, private Bitcoin payments. Bitcoin Indonesia's own Fedimint federation is estimated at 10,000-20,000 members.

Every graduate who runs a full node, submits a pull request, or teaches another Bitcoiner represents a direct, measurable strengthening of Bitcoin's open-source network.
