Zcash has announced "Project Tachyon," an upgrade designed to significantly enhance its network's capabilities. This initiative aims to scale Zcash's shielded transaction throughput to thousands of transactions per second (TPS) using a technology called "oblivious sync." This development is expected to make privacy features more instantaneous and globally accessible, potentially marking a pivotal moment for Zcash akin to Solana's "Firedancer" upgrade.
