Founder & CEO
Bitcoin Castle Promenade
I'm the Founder & CEO of Promenade, a local bitcoin cafe in Korea, and a builder of Sea of Corea, a grassroots Bitcoin mining initiative. I run Bitcoin mining infrastructure and host hands-on workshops using open-source technology such as Bitaxes and DATUM. Our work brings together local hashpower, self-custody, mining pools, nodes, and practical education so more people can participate directly in the Bitcoin network. Sea of Corea is a grassroots project to decentralize concentrated power and rebuild from the ground up with Bitcoin: a grassroots, sovereign platform owned by the people who use and build it.
