How does Kaspa's Rust rewrite enable block parallelism?

Kaspa's Rust rewrite enables parallelism — the ability to process different blocks on different CPU threads simultaneously. Modern computers contain many processing cores that can work independently at the same time, but older software designs often leave most of those cores idle. Rust allows race-ready concepts that fully utilize this modern computing hardware, so Kaspa can spread block processing across multiple CPU threads at once rather than handling each block in a single queue. Go, the original language, was suited for proving the design concept but was not built for this kind of hardware-level throughput. For beginners, parallelism means the network is not bottlenecked to one task at a time — it can work on many blocks in parallel, which is foundational to Kaspa's ability to operate at high block rates.
