## Content

The Sui blockchain operates at a speed and scale previously thought unattainable. Sui assumes most blockchain transactions touch non-overlapping states, meaning that transactions can run in parallel. Sui optimizes for single-writer objects, allowing a design that forgoes consensus for simple transactions. Instead of the traditional blockchain’s fire-and-forget broadcast, Sui's design enables a requestor or a proxy to proactively talk to validators to bring a transaction to finality. This results in near instant finality for simple transactions.
