In 2018, Solana founder Toly introduced himself and Solana's precious images

In this precious interview video from 2018, Solana founder Toly talks about his technical background: he is engaged in operating system development at Qualcomm, is the core developer of the BREW kernel, and even writes more than half of the kernel according to the volume of objects, and is responsible for the compiler and code generation part.

He then delved into the DSP structure on the processor, understanding how modern mobile chips compress many components onto the same silicon wafer, and thinking about how time-stepping solves synchronization problems from the perspective of “distributed systems.”

It is on the basis of these underlying engineering experiences that Toly leads to Solana’s key innovation – Proof of History. He describes it as a way of “encoding time into data,” allowing on-chain nodes to advance state updates at a faster and more uniform pace. This design eventually became the core idea of Solana’s high-performance architecture.
