According to Cas Abbé, Sallar is a DePIN network built on Solana that leverages billions of smartphones globally to create a decentralized AI supercomputer. By connecting modern smartphones as nodes, Sallar enables distributed computing for tasks like AI model training, data analysis, and cryptography, rewarding users with $ALL tokens. This model reduces reliance on centralized GPU clusters, making AI development more affordable and accessible while driving the adoption of decentralized infrastructure.
