The Blueprint for Bitcoin’s Next Era

Bitcoin Thunderbolt is not just an upgrade, it’s a blueprint for the future. Outlined in a whitepaper authored by the Nubit team as core contributors and leading researchers, Thunderbolt introduces a breakthrough off-chain transaction model that redefines speed and scalability for Bitcoin, without compromising its core ethos.

At the heart of Thunderbolt is a carefully engineered system: tweakable Schnorr signatures, threshold signature committees, and rigorous cryptographic design all working together to bring Bitcoin into a new era of efficiency and programmability.
