# 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 ](https://www.scribd.com/document/854130348/Bitcoin-Thunderbolt-A-Formally-Verified-Protocol-for-Off-Chain-Bitcoin-Transfers)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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
