Some technologies that changed the world were once dismissed. It took people willing to build businesses around them to show what they could do.

At the @btckoreaconf, @powdae shared those stories with a challenge for

Bitcoiners: What do you wish existed? Go build it.

Louis (@powdae) of @Coconut_BTC @Nonce_Lab presents bitcoin through a Korean cultural frame. 🇰🇷

He compares the adoption of Korean Hangul alphabet to the adoption of Bitcoin.

Using a native alphabet instead of Chinese characters was good for Korean sovereignty and independence from China. Yet, it was still met with resistance.

It took hundreds of years for Hangul to become mainstream. Today it is foundational to the independent Korean nation.

Louis draws big crowds, and is a respected elder of the Korean bitcoin community.

Proud to have Louis (@powdae) on stage at @btckoreaconf this Sunday.

CCOS and the builder network are on the table — Korea's builders, devs, and community leaders each get a stage to show what they've been building.

If you're at @btckoreaconf, this is the one🚀

Our Bitcoin Center Seoul team was on Korean national TV (SBS) this morning, invited to talk about exchange security after a recent hack.

We naturally brought up self-custody. That part got cut, and we were introduced as 'people using crypto exchanges' 🥲

If you cover exchange hacks, you should cover self-custody too.

오늘 SBS 모닝와이드 3부에 비트코인센터서울이 나왔습니다.

최근 바이낸스 해킹 ���건과 관련해, 국내 거래소 보안에 대한 우려를 비트코인 투자자의 관점에서 듣고 싶다는 인터뷰 요청이었어요.

거래소의 위험성을 잘 알고 있기에 자연스럽게 셀프커스터디 이야기를 꺼냈는데요. 현장에서는 그 이야기는 그만하고 투자자 관점에서 얘기해 달라는 요청을 받았습니다.

그렇게 방송에 나온 저희의 소개는 ‘가상화폐 거래소를 사용 중인 사람들’ 🥲

거래소 해킹이 걱정된다는 이야기는 나갔지만, 비트코인을 직접 보관하는 방법에 대한 이야기는 편집됐습니다.

거래소 해킹을 다룬다면, 셀프커스터디도 함께 다뤄야 하지 않을까요.

갑작스럽게 잡힌 일정임에도 선뜻 촬영에 참여해 주시고 이야기를 나눠주신 @powdae, @nldd21, @JIN_1337, @dongguri2100 께 감사드립니다 🙏

저희 출연 장면은 유튜브 영상에��� 없지만, SBS 공식 홈페이지의 오늘 모닝와이드 3부 8996회 다시보기에서 보실 수 있습니다.

시드사이너랑 크럭스 멀티벤더로 멀티시그 구성하신 분들은 조심하세요.

멀티벤더, 멀티시그를 하는 이유는 한 기기가 뚫려도 비트코인을 지키기 위해서입니다. 그래서 보통은 서로 다른 제조사의 지갑을 섞어서 구성하곤 합니다.

실제로 많은 분들이 제조사 리스크를 피하기 위해 SeedSigner와 Krux로 멀티시그 지갑을 구성하시는데, 이 조합은 완벽한 분산이 아닙니다.
왜���까요?

겉모습도 개발 팀도 다르지만, 깃허브를 확인해보면 둘 다 embit이라는 동일한 ���트코인 라이브러리를 기반으로 작동하고 있습니다.

만약 embit에 치명적인 버그가 발생하면 두 기기가 동시에 동일한 오류를 일으킬 수 있습니다. 결과적으로 2-of-3 멀티시그에서 두 키가 같은 이유로 무너지면 멀티시그의 의미가 사라지게 됩니다.

멀티시그의 핵심은 단순히 서로 다른 '기기(하드웨어)'를 쓰는 것이 아니라, 서로 다른 '소프트웨어 구조'를 조합하는 것입니다. 멀티시그를 구성할 때는 제조사뿐만 아니라 내부 라이브러리 의존성까지 확인해 보는 습관이 필요합니다.

최근 BOSS Summit에서 Krux 개발자를 직접 만나 나누었던 이야기입니다. 비트코인 센터 서울@BtcCtrSeoul 에서 크럭스를 판매하고 있다니까 깜짝 놀라했습니다.

크럭스와 시드사이너를 섞어 멀티벤더를 구성하는 비트코이너들이 많으니 "이 위험성을 한국에 꼭 좀 전해달라"고 당부했습��다.

비트코인 커뮤니티의 안전을 위해 선뜻 이 위험성을 공유해 준 개발자분께 감사드리며, 저 역시 더 많은 분들과 공유하고자 이 글을 작성��니다.

A HUGE thank you to our sponsors that made Bitmela happen ✨

[Bitshala @bitshala_org]

From three days of BOSS Summit in Jaipur to two days on the Bitshala FOSS Stage at @thebitmela, it has been quite a journey.

We went deep into the work: Bitcoin Core, wallet development, Lightning, privacy, Nostr, cryptography, security, open-source infrastructure, and much more. We saw developers take apart difficult problems, share code, run workshops, test ideas, and put their projects in front of the community.

Few highlights: We mined testnet coins with @powdae, raced to claim 36,000 sats through Coconut Wallet, explored fuzzing Lightning implementations with @nishant282003, built with CDK, saw the Formstr stack by @HeyFormstr, CryoBrick by @apalok21, OpenSwap by @citadelfoss, and witnessed the official launch of Shroud by @theanmolsharma_.

We also had conversations that matter just as much: how to teach Bitcoin, build stronger communities, create sustainable businesses, protect privacy, and make self-custody accessible to more people.

And perhaps the best part was watching people learn from one another. First files uploaded to Formster Drive, sats earned, questions asked, ideas challenged, connections made, and new friendships formed.

To every speaker who shared their work, every builder who showed up with something to demonstrate, every attendee who asked a question, every volunteer who made things happen, and everyone who spent these five days with us: thank you 🙇‍♂️

This is what building an ecosystem looks like. Not just big announcements or finished products, but people showing up, sharing knowledge, helping each other, and putting in the work.

We came together to build, and we leave with more ideas, stronger connections, and plenty of work still ahead.

The stages are coming down, but the building continues.

Until next time 🚀🧡

[Raj⚡🌋 (🏗️ bitshala) @RajarshiMaitra]

The best feedback I have ever received on the summit from one of the dev was "wtf, this can't be real".

We exist to bring the dream down to reality. Something that otherwise wouldn't have existed, that wouldn't have scaled, not only exists but also going strong. And I cannot be more proud of the @bitshala_org team and what we have achieved so far. This feels dreamy for me too.

My sincere thanks and gratitude to all those who participated, all those who displayed extreme high energy in a continuous doomsday news cycle, and to those cypherpunks who commit their lives to bring Freedom Tech into existance. Thank you for all that you do. We exist to serve you.

Thanks to all our supporters who beleived in us and guided us along the way. We couldn't do it without you. @HRF @OpenSats @btrustteam.

And lastly thanks to @Vinteum_org @Coconut_BTC and @CodeOrangeDevs for sending their representatives to share the space with us. We learned a lot from each other.

What each summit brings is the hightened sende of belonging, reminder of the mission, and guides for the path forward. To fix the money. And in turn, to fix the world.

One line of code at a time.

Onwards and upwards. 🚀

[Bitmela @thebitmela]

It was amazing having the @Coconut_BTC team with us in Jaipur, connecting with the Indian Bitcoin community and sharing their experiences of building in Korea.

Here’s to stronger connections between India and Korea and many more such meetups ahead! 🇮🇳🇰🇷

[Bitmela @thebitmela]

What does money mean where you live? 4 people. 4 perspectives. Join us at the Cake stage now!

[NonceLab (Team Coconut) @Nonce_Lab]

We loved spending four days with the @bitshala_org, getting to know the developers and sharing what we’re building at @Coconut_BTC. Their passion for Bitcoin and the conversations we had gave us plenty to learn from.

At @thebitmela, we got to share our experiences building Bitcoin communities in Korea and meet so many of our users in India face to face at the booth. Hearing their questions and perspectives was especially meaningful for our team.

Thank you to the Bitshala and Bitmela teams for welcoming us so warmly.

We’re leaving Jaipur grateful for the old friends we reconnected with and the new ones we made. We hope these connections with India continue to grow!
