$KAS . New Capabilities In Toccata According to the official Toccata hard fork node guide, the upgrade activates at a specific difficulty adjustment score, roughly June 30, 2026, 16:15 (UTC). Toccata adds “native L1 covenant programming,” meaning transactions can enforce rules on how outputs are spent in the future, and it provides infrastructure for zero knowledge based applications directly at the protocol level. This moves Kaspa beyond simple transfers toward more expressive, programmable transaction logic while keeping its proof of work blockDAG design. These changes align with earlier roadmap work around the Rust rewrite and high throughput testnets, positioning Kaspa as a high performance, more programmable PoW network rather than a basic payment chain.
