Speakers

Adam Gibson (aka Waxwing) is a Bitcoin developer and privacy researcher best known for his work on JoinMarket, one of Bitcoin's most prominent CoinJoin implementations. He is one of the most respected voices in Bitcoin privacy and fungibility.

Dan Gould is a Bitcoin privacy developer, lead developer of the Payjoin Dev Kit and founder of the Payjoin Foundation. His work on serverless payjoin (BIP 77) makes privacy-preserving payments practical for everyday wallets and exchanges, and is shipping in integrations with Bull Bitcoin and Cake Wallet.

Daniel James is the founder and CEO of Wallet of Satoshi, a wallet built on the Bitcoin Lightning Network (a Bitcoin Layer 2 technology for fast, low-cost payments). Since its launch in 2019, Wallet of Satoshi has processed more than 19 million transactions and established itself as the most widely used Lightning wallet in the world. Before Wallet of Satoshi, he founded and ran Living Room of Satoshi in 2014, which allowed users to pay utility and household bills with Bitcoin — making him one of the entrepreneurs with the longest hands-on track record in the Lightning payments space. At this conference, he will speak on strategies for mainstreaming the Lightning Network and expanding Bitcoin payment infrastructure.

Duncan Dean is a Bitcoin Lightning Network developer, currently contributing to Bark, Second's implementation of the Ark protocol. Ark is a next-generation Bitcoin Layer 2 solution designed to address Lightning's channel management complexity and liquidity challenges, enabling users to make instant, low-cost off-chain payments without operating their own channels.

Fabian Jahr is a Berlin-based Bitcoin Core (the standard reference software for the Bitcoin network) developer. His work spans a wide range of efforts to improve the stability and scalability of the Bitcoin protocol — from research on Schnorr signature–based technologies, to in-depth review of critical pull requests, to development of ASMap (a technology that improves the geographic and network decentralization of nodes). In recognition of his research, he was recently selected as a CISA (Cross-Input Signature Aggregation, a Bitcoin signature aggregation technique that can significantly improve transaction efficiency) Research Fellow at the Human Rights Foundation (HRF), and published a 38-page industry report analyzing the impact CISA could have on the Bitcoin ecosystem. At this conference, he will draw on this experience to discuss recent developments in Bitcoin Core, and what the next generation of protocol upgrades — including CISA and Schnorr signatures — means for Bitcoin.

Jimmy Kostro is an American entrepreneur and U.S. Marine Corps veteran, and a passionate Bitcoin advocate based in Chiang Mai, Thailand. He co-founded two logistics companies and grew them into multi-million-dollar businesses spanning 24 markets across the United States. A steadfast Bitcoiner since 2017, Kostro has devoted himself to building one of Asia's most active Bitcoin hubs, and has become a leading voice in showing how Bitcoin can be a powerful tool for financial freedom and sovereignty — especially for people living under authoritarian regimes in Southeast Asia. He serves as chairman of The Kostro Foundation, a U.S. 501(c)(3) non-profit that provides education and Bitcoin literacy programs to underserved communities in Thailand. A passionate ultramarathon runner who has competed in races around the world, Kostro loves to draw a powerful parallel between endurance on the trail and Bitcoin's long-term resilience.

Based in Waterloo, Canada, Matthew Vuk works as a researcher at Second, the company developing Ark, a Bitcoin Layer 2 payment protocol. Ark is a Layer 2 protocol that aims to enable off-chain Bitcoin transactions at very low cost, without complex pre-setup such as opening channels. It works directly on top of today's Bitcoin without consensus rule changes or new op_codes, offering easy onboarding, low and predictable fees, instant settlement, Lightning Network compatibility, and control over one's own funds. The protocol revolves around an 'Ark server': users connect to this server to transact directly with one another, and can also transact with the broader Lightning Network through the server's Lightning gateway. At the heart of Ark is a new scaling model called the 'virtual UTXO (VTXO)' — a series of pre-signed off-chain transactions that a user can broadcast on-chain to reclaim their funds at any time in an emergency.

Starting from Corn Gang, Korea's first Lightning node community, Pororo is building Corn Wallet, an easy and convenient Lightning wallet. Believing that Bitcoin should be simple, Pororo is also active as an educator and lecturer.

Rama is a software engineer and Bitcoiner who has devoted himself to making the future of self-custody simpler and more robust. The tool he created, Penlock, is a printable encryption wheel that lets anyone split a seed phrase into a 2-of-3 multi-phrase backup using nothing but paper and pen — no electronics required. Because only two of the three pieces are needed to recover assets, the setup stays secure even if one is lost or stolen, and a breach of any single location never exposes the whole. Most importantly, even if the original mnemonic (seed phrase) is lost entirely, the full seed phrase can be reconstructed from any two of the three pieces using the Penlock wheel. This lets users design remote recovery and inheritance plans on their own, without relying on any company or third party. No power, no battery, and no internet connection is required — Rama has focused on 'low-tech' solutions that anyone can hold in their hands and use directly, rather than flashy technology. His work is an attempt to realize Bitcoin's ideal of 'being your own bank' without compromising on privacy, security, or sovereignty.

Respect is a YouTuber who runs the channel 'Respect Investment Plan.' From the perspective of a working professional pursuing financial independence and freedom of time, he focuses on understanding the essence and volatility of Bitcoin and interpreting it through a long-term lens — delivering the big-picture market flow and asset allocation strategies through in-depth interviews with a wide range of experts. What sets him apart is his ability to translate the complexity of Bitcoin into everyday language, and he has built lasting influence in Korea's Bitcoin content ecosystem on that strength. At this conference, he will speak on the structural value of Bitcoin and strategies for navigating market cycles.

Robin is a European-born developer who has lived in Korea for more than five years, and the founder of 'Bitcoin in Pusan,' a Busan-based Bitcoin community. Before starting Bitcoin in Pusan, he worked as an open-source developer in the ecash space, contributing to Bitcoin ecosystem projects, and has long been interested in connecting Bitcoin technology to the lives of real users. He created Bitcoin in Pusan at a time when the region had no Bitcoin community at all; within just one year of its launch, it grew into a community with regular meetups, lectures, workshops, and events — as well as its own physical space. At this conference, Robin will share the experiences and lessons he gained over the past year building Bitcoin in Pusan, and will talk about how anyone can build their own Bitcoin network.

Spector is a Bitcoiner who has devoted himself to building up Korea's Bitcoin community on a solid foundation. He has consistently held offline meetups to grow the domestic community, and personally runs education programs for newcomers encountering Bitcoin for the first time. By planning and building out the (former) Bitcoin Mini Conference — the largest 'Bitcoin only' event in Korea — he proved firsthand what the power of community can be. He has also taken the stage as a speaker at overseas conferences, bringing diverse cultures from abroad into Korea while serving as a bridge that introduces Korea's Bitcoin industry to the world. Rather than flashy discourse, he has steadily devoted himself to the 'work on the ground' — helping people gather, learn, and take sovereignty over their own assets in person. His path is bringing Bitcoin's ideals to bloom in the language of community, on Korean soil.

Stephan Livera is the host of the Stephan Livera Podcast (SLP), a show that dives deep into the economics and technology of Bitcoin. A longtime student and advocate of the Austrian school (an economic tradition emphasizing free markets and sound money), he is listed on the Mises Institute's official profile page and has consistently worked to interpret Bitcoin through an Austrian-economics lens. SLP has surpassed 6 million cumulative downloads and holds an average rating of 4.9 across more than 700 reviews worldwide — placing it in the top 0.5% of global podcasts and establishing it as one of the flagship podcasts in the Bitcoin space. On the strength of that influence, he is a regular speaker at major Bitcoin conferences around the world. At this conference, drawing on the rich body of interviews he has accumulated over the years, he will share insights on the economic and technical currents in Bitcoin and the latest developments in global markets.

네딸바 is a Bitcoin YouTuber and translator. He translated 'The Blocksize War' and 'The Bitcoin Standard' into Korean, helping bring foundational Bitcoin literature to Korean readers.
