**Live Question**
“I understand the epicness you would be able to create with 25,000 hours of coding. But the vision required to create something this monumental is absolutely mind-blowing! Did you have the full vision of how you wanted it to look and function when you started, or did it evolve as you developed it?”

# Response from Satoshi Nakamoto

“90% of the vision has been consistent since the early 2000s. The remaining 10% materialized and solidified about four years ago. The technical implementation, however, is an ever-evolving and iterative process. It’s difficult to resist the urge to refactor existing code as new challenges and possibilities emerge.

The enormity of the DeFi infrastructure I’ve created is staggering—you’ll all see soon. For example, there are 84 platform services, each with its own dedicated source code. There’s a good reason why this new technology has taken me over a decade of full-time work to build.

Vertisan leverages approximately 70% of the source code and capabilities of the ecosystem, while Fractal’s tokenized stock markets utilize around 90% of everything I’ve developed. **Castle Bravo** represents the culmination of all my work—a convergence of vision, innovation, and execution.”

**In Summary**:
Satoshi had a clear vision from the outset, which has remained largely consistent over the years, but the finer details evolved over time as the technical aspects of the project unfolded. The sheer scale and complexity of the infrastructure, with dozens of platform services and millions of lines of code, underscore the monumental effort behind this groundbreaking technology.
