Panel discussion

Money Backed by Energy

Europe’s energy crisis has exposed the flaws of centralized planning and short-sighted green policies. Bitcoin offers a new path—one where energy and money are aligned. This session explores how mining can incentivize local energy production, support grid balancing, and unlock stranded power. We’ll cover legal precedents, policy threats, and the latest in mining tech like Stratum V2. As the world rethinks energy and sovereignty, Bitcoin is emerging as a bridge between the two.

Bitaxe Open Source Bitcoin Mining

While Bitcoin is dominating the world, the systems that create new Bitcoin "mining devices" are closed source to the public. The Bitaxe project aims to solve this problem and bring open source back to the mining industry.
