Can Kaspa add additive addresses without a network-wide upgrade?

Yes — additive addresses can be deployed on Kaspa using only the existing P2SH mechanism, with no consensus changes required. A consensus change (sometimes called a hard fork) means every node on the network must update simultaneously, which is complex to coordinate. P2SH (Pay-to-Script-Hash) is an already-live Kaspa feature: a custom spending script is written, then hashed, so the address only stores the hash and not the full script. A public key and a threshold value can be bundled into such a script to enforce additive-only spending rules — and because P2SH only stores the hash, the original script details cannot be reverse-engineered from the address. For beginners, this matters because features that skip consensus changes are simpler and safer to introduce, meaning additive addresses could arrive sooner and with less risk than a full protocol upgrade.
