How does Kaspa schedule a network-wide opcode upgrade?

Kaspa ties major network upgrades to a predetermined DAA score that is announced well in advance, rather than a calendar date. A DAA score is a network-level counter that all participants can track, so everyone can see exactly when the change will take effect. Announcing the target DAA score early gives node operators the time they need to download and install the updated software before the threshold is reached. This coordination matters because it keeps the whole network moving together — by the time the activation point arrives, operators have had a clear runway to upgrade and avoid being left behind.
