What is the Toccata Mainnet pre-release?

The Toccata Mainnet pre-release is a test build of the upcoming Toccata upgrade released to the Kaspa community for sanity-testing before the final rollout. Kaspa protocol upgrades go through staged community testing to verify compatibility across real-world node setups — different upgrade histories, pruning states, and operator configurations. This particular pre-release does not activate Toccata on mainnet; its only goal is confirming that existing mainnet behavior stays compatible with the new release before anything changes for real. Node operators, pools, and miners are encouraged to test on a limited subset of their infrastructure rather than fully migrating. For everyday Kaspa users, this staged process means major protocol changes are carefully vetted by the community before they affect your wallet or transactions.
