We said explain Blitzar in 30 seconds, and ZK-Jay delivered ZK proofs are compute-intensive, which makes them both slow and expensive to run. One solution is offloading some of the compute to specialized hardware, like GPUs. The GPU accelerates the proof, making it faster and more affordable to run. Blitzar is the layer that sits between the proof software and GPU hardware to facilitate this acceleration.
