# NestBFT NestBFT is a **Byzantine Fault Tolerant** consensus mechanism designed to provide fast, scalable, and fault-tolerant blockchain operations across all Canopy chains. It ensures that sub-chains can maintain high uptime and security, even if up to one-third of validators fail or act maliciously. 💡Unlike Proof-of-Work (PoW), NestBFT does not rely on intensive computation, making it environmentally friendly while guaranteeing that Canopy chains can operate smoothly during all phases of their evolution, including independence. {% hint style="success" %} In this section, you'll read about some of the core features of Canopy's unique consensus algorithm {% endhint %} --- # 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.
